Can the wheat be watered when it is full?

Wheat needs watering after it is full, commonly known as wheat yellow water.

During the harvest season, the seeds of summer crops begin to be full, but they are not yet mature. Xiaoman is around May 2 1 of the Gregorian calendar every year, and it is the eighth solar term in the twenty-four solar terms of the lunar calendar. At this time, it is the immature "filling" period of wheat, so it is called "Xiaoman".

At this time, special attention should be paid to field management and watering to ensure the growth of wheat. As the old saying goes, "a grain of wheat is dangerous when a villain is dissatisfied." This "one risk" means that wheat has just entered the stage of milk ripening at this time, and it is very vulnerable to dry and hot winds, which leads to insufficient grain filling, grain shrinkage and reduced yield.

Extended data:

Dry-hot wind is very common in China, which often occurs in early summer. It is an agricultural disastrous weather, characterized by high temperature, drought and certain wind force. In the later stage of wheat growth, dry and hot wind will lead to insufficient wheat filling, premature drying of wheat, shrinkage of wheat grains and decrease of yield. Attention should be paid to the following points in agriculture:

First of all, we can reduce the harm of dry-hot wind on a large scale by planting trees and building windbreaks. Afforestation can not only reduce wind power, but also improve farmland climate, reduce temperature and speed up wheat filling, which is the fundamental method to prevent dry-hot wind and increase wheat yield.

Second, select excellent wheat varieties with strong resistance to dry and hot wind, and increase wheat yield through reasonable cultivation and fertilization. In addition, in the early stage of wheat development, irrigation should be timely and appropriate to reduce the humidity of wheat fields. Generally, irrigation water should be poured 2-3 weeks before wheat harvest. If the weather is dry and rainy in the early stage, water it in advance to reduce the harm of dry and hot wind. Note that if the wheat is too dense, there is no need to water it to avoid lodging.

3. Spraying pesticides on wheat leaves at the late stage of wheat growth and before the arrival of dry-hot wind can not only accelerate the growth and development of wheat at the later stage, reduce the harm of dry-hot wind, but also be beneficial to wheat filling and wheat grain fullness, thus increasing wheat yield.
