As the agricultural proverb goes, the white dew is early, the cold dew is late, and the autumn equinox is just at that time. Does this sentence still apply now?
The white dew is early, the cold dew is late, and the autumn equinox is the time to plant wheat. This is a proverb that I read many times every autumn when I was a production captain forty years ago.
At that time, every summer solar term, the commune or county would hold an autumn harvest wheat mobilization swearing-in meeting to give us the wheat planting indicators. We captains also have to make an oath, show our determination, overcome difficulties, grab the harvest and grab the seeds, and we must fight the battle of planting wheat in autumn.
When you come back, you should arrange the autumn harvest, break the sticks and transport fertilizer. Tractors from the commune tractor station are also assigned to teams. Hafnium's task is to rest people and horses and run quickly.
Therefore, we call for mobilization, so we should be busy ensuring the white dew tail and autumnal equinox of wheat, try not to plant cold dew wheat, and resolutely not to plant first frost wheat.
Because, our wheat in Hebei plain is suitable for sowing in autumn equinox. Wheat in Bailu grows too vigorously, and it is easy to jointing before winter. The cold and dew wheat is a little late, and there are not enough tillers. Only the wheat planted at the autumnal equinox tillered long before the arrival of winter, without jointing. Cold dew wheat is a little late, and there is a proverb, "the first frost wheat does not fall, but the cold dew wheat has a small mound", which means that the wheat after cold dew is too late.
In recent years, the climate has changed and become warmer. Wheat does not die in winter, and there is no need to turn green in spring. After the autumnal equinox in beginning of winter, the wheat at jointing stage will not be able to survive the winter, and the tillers in spring will not be separated, resulting in sparse wheat fields and ultimately reduced production.
The climate is getting warmer, autumn is wrong, and winter is not cold. It is impossible to read this old almanac that "the white dew is early, the cold dew is late, and the autumn equinox is planting wheat at the right time". According to the current climate change, this proverb should be changed to "Autumn Equinox is early, beginning of winter is late, and the first frost is cold".
When the greenhouse effect has passed and returned to the previous climate, let's "plant wheat at the right time in the autumn equinox".
The white dew is early, the cold dew is late, and the autumn equinox is the time to plant wheat.
Listen, these jingles are very kind. Anyone who has been to or lived in the countryside knows the meaning of these farmhouses.
Agricultural proverbs are the essence of farmers' productive labor for thousands of years, and they are universally applicable truths in rural areas of China.
In rural areas, every kind of food crops, vegetables and fruits has a set of farm season jingles, which are easy to remember and understand, and can also be passed down from mouth to mouth.
Rural areas attach great importance to farming season. When to plant wheat, when to plant radish, when to harvest wheat and when to pull out radish, there are specific times. If you miss them, you will get into trouble.
Although great changes have taken place in rural planting patterns and vegetables and fruits are out of season, it is still necessary to observe the farming season of food crops.
The planting pattern in the south is different from that in the north, and the details are not clear.
But in the north of Huaihe River, even in the north of Yangtze River, the agricultural season of growing wheat is basically the same.
Today is September 22nd, the autumnal equinox among the 24 solar terms. We have just finished pulling peanuts in rural Jiaodong, and we are going to turn the land out to grow wheat. However, people don't plant around the autumnal equinox as they did a few years ago, and they often postpone several solar terms because the original lunar calendar is no longer applicable.
I remember that a few years ago, we used to plant winter wheat around the autumnal equinox in rural areas in northern China. Agricultural proverbs often say that "the white dew is early, the cold dew is late, and it is the right time to plant wheat", because the time of this wheat is summarized according to the local climate. The autumnal equinox and solar terms have passed. Why are people in no hurry to plant wheat now?
Due to the global warming in recent years, the phenomenon of warm winter has also appeared in rural areas in northern China. If we still sow according to the time of the agricultural proverb, the wheat seedlings will grow sturdily in winter. If the cold wave comes, the wheat seedlings will be frozen, so the sowing time will have to be postponed. According to the current situation, the planting of wheat is basically delayed for about half a month, that is, after the cold dew solar term and before beginning of winter.
It can be seen that the old almanac has fallen behind the times.
The so-called autumnal equinox planting wheat was a thing of the past at that time. In the past, farmers always planted crops according to the solar terms, but now they need to sow according to the weather changes.
If we plant wheat according to the solar terms, these days are just the sowing season of wheat. Today's autumnal equinox, around the autumnal equinox, is the best time to plant wheat in the past, but we certainly can't plant wheat according to agricultural proverbs this year. At that time, what was the autumnal equinox for planting wheat? The crops were still standing in the fields, so we had to plant wheat before the land was cleared.
Maybe it's the leap month this year? Although the autumnal equinox solar term has arrived, many crops are not mature at all. In recent days, peanuts have been pulled out, and the beans in the field are still green. If you want to harvest, it is estimated that you will have to wait for another solar term, and many crops will mature in ten days and a half months.
The phrase "early Millennium" is correct. During the Millennium solar term, no farmers planted wheat, and the weather was still hot. After wheat is planted, it will germinate and grow early. When the soil is frozen, it is estimated that the elders of wheat seedlings are too high, which will lead to excessive prosperity of wheat seedlings, and the roots of wheat seedlings will wither and yellow next spring, or various wheat diseases will occur.
In addition, now that wheat seeds have been replaced, there is no need to have strict requirements on temperature as in the past. Wheat seeds can adapt to the temperature of 16- 18℃. This autumn equinox, the temperature is still above 26℃, so there is no need to sow wheat so early.
We all know that the earth is getting warmer and warmer in general, especially in winter. People often say that it is warm this year, so sometimes it is winter, but the temperature is as warm as spring. Solar terms have long changed according to temperature changes, and sowing wheat is no longer based on agricultural proverbs.
In recent years, farmers have put off wheat planting until the first frost for various reasons, saying that it is too late to plant wheat in the first frost, but farmers have tried. Wheat planted in the first frost can sprout before the soil freezes and will not delay the growth in the coming year.
The weather that can't be seen through has long lost its previous role for agricultural proverbs. Planting wheat should be based on experience and weather changes!
I'm Simon Beaufort. I'll answer this question.
This sentence still applies now.
My hometown is located at the southernmost tip of Shanxi, at the junction of Shanxi, Shaanxi and Henan provinces. The terrain is divided into three steps: the first step is mountainous, with an altitude of about 1000 meters; The second step is on the city wall, about 700 meters above sea level; The third step is the lowest, and the beach on the bank of the Yellow River is about 500 meters above sea level.
The agricultural proverb circulating in my hometown and countryside is similar to this: "Planting mountains in the white dew, planting flat walls in the autumn equinox, and planting beaches in the cold dew", and planting wheat is just in these three solar terms.
There are three towns and villages in my hometown, one is Zhangdian, the other is Qinglan and the other is Guanbu. These three towns and villages began to sow wheat around the Millennium every year. There are eight or nine towns on the second step, and it is most suitable to sow wheat around the autumnal equinox every year. The wheat seedlings in Zhangdian, Qinglan and Guanbu all came out, and planting began when they went to the wall. There were fewer seed fields and more wheat seeds tillered. There is almost no land in the lowest Yellow River beach area along the river, and only part of the three towns are located on the third step. Because the terrain is low and the ground temperature is higher than the second step, seedlings will flourish in the early stage of planting, so it is best to sow before and after cold dew.
There is also an agricultural proverb in my hometown: it is not cold and the ground is not frozen. As long as there are seeds, plant them. This means that as long as the weather is not too cold and the ground is not frozen, wheat can still be sown, that is, it can still be sown in the first frost, but there are more wheat seeds.
Although the technology is developed and the information is well-informed, this agricultural proverb is still very applicable to rural farmers in my hometown, and planting wheat every year is determined according to the solar terms.
Agricultural proverbs are proverbs about agricultural production and a summary of the long-term life and production practice of working people in China. The ancients created the "twenty-four solar terms" to guide agricultural production. Around these 24 solar terms, there are also many proverbs that arrange agricultural activities according to the timetable, such as "the white dew is early, the cold dew is late, and the autumn equinox is the time to plant wheat". However, China is a vast country, and the situation varies greatly in different places in the same season. Therefore, local agricultural production should not be guided by regional agricultural proverbs, but should be arranged reasonably according to local actual conditions, supplemented by agricultural proverbs. First of all, temperature is the main factor that determines the sowing date of winter wheat. The agricultural proverb "early dew, late cold dew, planting wheat in autumn equinox" also depends on the temperature. White dew (September 7-8), autumnal equinox (September 22-24) and cold dew (June 65438+10/October 7-9) are separated by half a month, and the temperature gradually decreases.
As we all know, the temperature in the past winter was much lower than now. Especially in recent years, the climate is getting warmer and warmer, so these ancient agricultural proverbs must keep pace with the times and not stick to the rules.
The second is the change of wheat varieties. We don't know what kind of wheat was sown in the past. At present, we have winter wheat varieties (suitable temperature is16–18℃) and semi-winter wheat varieties (suitable temperature is14–16℃). Due to the different temperatures required, the sowing date is early or late.
Generally speaking, when the average temperature of the day is14–18℃, it is the best sowing date for winter wheat.
I don't know when the suitable sowing date of winter wheat is in your place. As far as Anqiu in Weifang, Shandong Province is concerned, the suitable sowing date of wheat is from 65438+ 10 to 65438+ 10. However, this time period is around the cold dew solar terms, but it is not as "cold dew is too late" as the agricultural proverb says. We have an agricultural proverb here called "Don't apply manure to cold dew wheat", which also shows that it is not too late to sow wheat in cold dew.
Second, in fact, I have a piece of land that is a typical waterlogged depression. In our words here, "this is the land of waterlogged frogs." One autumn, it rained continuously, and the corn in the field was rotten. Other people's wheat was "small" and my land was still in rotation. It's almost over, and it's been several days since the first frost solar terms. Shall we sow wheat?
Some old people said to me, "just sow, plant more seeds and apply more fertilizer." Why is there such a thing as "burying your head" Listen to the old man. Play it. Don't tell me. It's okay. Although the output is lower than others, it is not much different, and the yield per mu is also above 800 kg.
I have a friend whose land grows ginger, but the stinky ginger that year is almost worthless, and 25 cents a catty is not enough to pay for ginger. When he finally finished producing ginger, it was the first 10 day after the first frost. He planted wheat without using seed fertilizer, but the yield was very good later. Because the ginger field is full of fat and full of water.
There are many examples to prove that the agricultural proverb "early dew, late cold dew, autumn equinox just planting wheat" is no longer suitable for today's wheat sowing. In my opinion, it should be "the autumnal equinox is early, the first frost is late, and the cold dew is sowing wheat at that time", which is similar, and the next solar term is just a little later.
There is also an agricultural proverb that says, "You can't plant wheat in the first frost, and you can't bear wheat after the first frost." . It means that after the first first frost solar term, the weather will be hard to feel. Maybe one day, when cold air comes and the ground temperature drops, the wheat will not germinate and even rot. Even if the seedlings can be unearthed, they will suffer because they are too thin to bear the frost, so they will wither without harvest and burden.
Therefore, it is best to sow winter wheat before the first frost. However, due to various reasons, wheat was sown late, so we can make up for the deficiency caused by late sowing by increasing chemical fertilizer, selecting semi-winter, spring-biased or spring-oriented varieties, increasing sowing amount, scientific management and other measures. This is the so-called four supplements and one promotion method.
Well, that's all about the sowing date of winter wheat. Anyway, I think the agricultural proverb "early dew and late cold dew, planting wheat at the autumnal equinox is just the time" is not appropriate here. Today is the autumnal equinox, but the corn cob here is even green. It takes 10 days to harvest corn, which is almost the same as sowing wheat in cold dew. As for my "waterlogged frog" land, because there is too much rain this year and there is no corn, it may be necessary to sow wheat before and after the first frost. Rural proverbs can be said to be very diverse. These old sayings are a summary of the life experience of the older generation and also reflect the traditional wisdom of the older generation. Therefore, the phrase "the dew is early, the cold dew is late, and wheat is planted at the autumnal equinox" mentioned in today's question is actually not in line with the current phenomenon.
As you all know, when there was no weather forecast before, or when people didn't have the equipment to watch the weather forecast, they would summarize the changes of natural meteorology according to the annual weather changes, so this old saying in the question is a proverb about weather changes.
However, now people's scientific and technological life is more and more developed, so everyone can check the weather changes in the past month at any time through the Internet, so at the same time, everyone can choose the right time to sow according to the weather changes.
It's the end of September. At this time, it is the time to harvest corn in the field. After harvesting corn, the next busy thing is to plant wheat. Therefore, wheat planting is usually carried out at the beginning of 10 or at the latest in the middle of 10. According to this time.
The white dew occurred in September, and the so-called cold dew was also in this period, which means that the weather is unpredictable and some changes may occur at any time, so there is something wrong with this old saying now. In a word, we should decide according to the weather change.
After all, planting now pays attention to scientific planting and management. Only in this way can the sown crops have higher yield. Therefore, when we study rural proverbs, we must make a correct explanation according to our present life.
The autumnal equinox is in the middle of the whole autumn, and the arrival of the autumnal equinox shows that half an autumn has passed. On the day of the autumnal equinox, the sun reaches the longitude 180 degrees, and directly hits the equator of the earth, thus making the time between day and night equal. After the autumnal equinox, the direct point of the sun began to enter the southern hemisphere from the equator, and the northern hemisphere began to enter short days and long nights. The climate after the autumnal equinox is characterized by obvious temperature difference between day and night, and the temperature drops day by day.
This year, the Millennium is on September 7th, the autumnal equinox is on September 22nd, and the cold dew is on June 8th. 10.
"The white dew is early, the cold dew is late, and the autumn equinox is the time to plant wheat." The suitable sowing time of winter wheat was defined, but the sowing time of winter wheat in most areas this year began in the first half of 10, and the sowing time of winter wheat was regional.
In other words, in the past, wheat was planted in the autumn equinox in most areas, but now the global climate is warming, and the climate zone in the northern hemisphere of China has moved northward. At present, the sowing time of winter wheat in most parts of the north has become a suitable time to plant wheat in cold dew, while in the south, it has been pushed to the first frost, and only particularly cold places choose to plant it at this time of the autumn equinox.
So this sentence will not be inapplicable now, which varies from region to region. However, for most areas, "the autumn equinox is early, the first frost is late, and the cold dew is planting wheat at that time" is more appropriate.
This agricultural proverb is wrong: it should be that the white dew is early, the cold dew is late, and the first frost is the time to plant wheat!
This agricultural proverb is still valid! This is the conclusion that farmers have grown wheat for hundreds of years. It depends on climate, wheat temperature and surface temperature. If planted too early, wheat will germinate, but it is easy to flourish before winter and will frostbite wheat seedlings, which will affect the normal growth of wheat after the New Year. If the plant is planted too late, the low surface temperature will affect the normal rooting and germination of wheat. At the same time, it will also affect the growth period of wheat and greatly affect the yield of wheat!
The first frost in the early autumn equinox was when Chi Hanlu planted wheat.
