Are there any tips for watering corn? Can corn be watered as long as it is dry?

Corn plants are tall, with wide leaves, rapid evaporation and rapid growth. Different growth stages have different reactions to water. Rational watering is the basis of high yield of maize. However, there is no need to water in case of drought. Timely watering at the peak of water demand has obvious yield-increasing effect, so it is not allowed to irrigate with large water to avoid lodging. It is reasonable to say that corn needs less water when sowing. Unless the soil is very dry and the seeds can't germinate, it needs to be watered, especially in the land with sticky soil. If there is not enough water, it must be watered. Some people think that the above watering effect is good, but the water fee is too high and uneconomical. In summer, you can use corn with wheat yellow water or wheat yellow water to kill two birds with one stone. Spring maize can effectively solve the problem by deep ploughing, fertilization and water storage in winter.

If the soil moisture is low, when sowing corn, 300~500 grams of diluted human excrement can be watered without digging holes and covered with soil, so that the emergence rate is high and Miao Zhuang. Practice has proved that plastic film mulching cultivation of corn can realize water-free circulation in the film, save water to the maximum extent, harvest corn about one month in advance, and increase production by more than 40%. Water the ceiling at most once when it appears. Corn is a tall stalk crop with developed root system and stronger drought resistance than other crops. It's not very dry, and it basically doesn't need artificial watering. Under what circumstances does corn need watering? If you find corn in the field, the leaves are rolled up at noon until the sun goes down, which means that the corn drought is very serious and needs artificial watering.

Corn is a vigorous growth period in summer, and drought or flood disaster is prone to occur in hot summer. Therefore, if you want to water the corn, you should listen to the weather forecast more. It is estimated that the corn can be watered without heavy rain for ten days. If there is heavy rain, I suggest you don't water the corn in case it rains and floods after watering. When pouring corn, we should master the following principles: try not to flood irrigation as much as possible, and the skill is to spray water in the corn field with a one-and-a-half-inch or two-and-a-half-inch sprinkler pipe, which can not only solve the problem of corn drought, but also prevent flooding from encountering sudden rainfall and floods.

In a word, I don't think corn should be watered if it is short, especially in drought. This is because corn is a tall crop, and it is easy for farmers to water the corn fields in the dog days. A few years ago, a farmer in my village watered it in the corn field in the dog days, because he died in the corn field at dawn. Therefore, I hope farmers will pay attention to it and advise them to weigh the pros and cons and think twice before acting.
