Can buckwheat and oats be grown in Yuncheng area?

1. Buckwheat and oats can be grown in Yuncheng area.

2. Yuncheng area climate

1. Yuncheng is affected by monsoon activities throughout the year and has a warm temperate continental monsoon climate. In winter, controlled by the dry and cold air flow of Siberia, the northwest monsoon prevails, and the climate is characterized by cold and dry conditions; in summer, controlled by the warm and moist air flow of the Pacific, the southeast monsoon prevails, and the climate is characterized by high temperature, rainy weather, concentrated rainfall, and frequent heavy rains and thundershowers. The annual average temperature is 13.3℃, ​​the average temperature in January is -2.2℃, and the average temperature in July is 27.4℃; the sunshine duration is 2039.5 hours; the frost period is from late October to early April of the following year, and the frost-free period is 212 days.

2. The multi-year average precipitation (1956-2005) is 525 mm, and the rainfall varies greatly between years. The maximum annual rainfall is 945.8 mm, which occurred in 1958, and the minimum annual rainfall of 305.0 mm, which occurred in 1997. Precipitation is extremely unevenly distributed throughout the year, with less in winter and spring, accounting for about 20% of the whole year, and particularly concentrated in summer and autumn, accounting for about 70% of the whole year; the precipitation in July and August accounts for about 40% of the annual precipitation. Affected by topography and climate factors, the regional distribution of precipitation is uneven, decreasing from 750 mm in the southeast to 500 mm in the northwest.

3. Buckwheat growth habits

1. Buckwheat grows in wasteland and roadside. Buckwheat likes to be cool and moist, is intolerant of high temperatures, drought and wind, and is afraid of frost. An accumulated temperature of 1000 to 1500°C can meet its heat requirements. Seeds can germinate in about 4 to 5 days when the soil temperature is above 16°C; the optimal temperature for flowering and fruiting is 26 to 30°C. When the temperature is -1°C, the flowers will die, and when the temperature is -2°C, the leaves and even the entire plant will die.

Buckwheat is a short-day crop. When the day length is reduced from 15 to 16 hours to 12 to 14 hours, the growth period is shortened. Late-maturing varieties are more sensitive than medium- and early-maturing varieties. Each plant can bloom more than 2,000 flowers, but the seed setting rate is very low. Only about 10%, coupled with the weak assimilation ability of the leaves, the flowers and fruits fall off seriously.

2. Buckwheat is a crop that requires more water. It requires twice as much water as millet and twice as much as wheat. When a seed germinates, it needs to absorb approximately 50% of its own dry weight of water. A large amount of water is consumed during the flowering and fruiting period. It takes twice as much water from flowering to harvest than from seedling emergence to flowering. The peak flowering period is the period of peak water demand. Its transpiration coefficient is generally 450~630. It is required that the relative humidity of the air cannot be lower than 30 to 40%. 3. Buckwheat does not have strict soil requirements. The root system is weak and the seed has poor soil support, so the soil layer is required to be loose to facilitate the emergence of seedlings and promote root development. It has rapid reproductive growth and strong fertilizer absorption capacity, and is suitable for planting in newly cultivated land. The soil acidity is required to be pH 6 to 7, and soil with heavy alkaline content is not suitable for planting. Every 100 kilograms of buckwheat seeds produced will absorb approximately 3.3 kilograms of nitrogen, 1.5 kilograms of phosphorus (P2O5), and 4.3 kilograms of potassium (K2O) from the soil.

4. Buckwheat is a crop that is sensitive to fertilizers. Adequately fertilized stems can produce numerous branches. Phosphate fertilizer can promote the formation of seeds and increase the secretion of nectaries. Use bees to assist in pollination, thereby increasing yields. The demand for potassium fertilizer is relatively high, but potassium salts containing chlorine can easily cause leaf spot disease.

5. When buckwheat blooms, it requires a large temperature difference between day and night; it is cold at night and high during the day, sunny and windless, with many flowers and abundant honey secretion. Honey secretion begins in the morning, and the secretion of honey is maximum at noon, then gradually decreases, and stops after 14 o'clock. However, due to sufficient sunshine and large temperature difference between day and night in the plateau area, honey secretion can be delayed until the afternoon. When the weather is foggy and then clear in the early morning after rain, honey secretion is at its peak. The optimal temperature for honey secretion is 25~28℃. When the temperature is below 25°C, honey secretion decreases as the temperature drops.

IV. Growth Habits of Oats

? Oats like cold weather, tolerate drought, salt-alkali, and have a short growing season. They often grow wild on hillside roadsides, alpine meadows, and in humid areas. at.
