How to water wheat from flowering stage to filling stage? What are the points for attention?

Dig a small pit directly in the wheat field with a depth of seven or eight centimeters. Look at the color, light yellow means less water. You can also grab this and dig it out. If it is loose and shapeless, it also means that there is little water and it needs to be watered in time. According to the soil moisture, irrigate grouting water timely and properly, and the watering time should be controlled within 15 days after wheat flowering. Strong gluten wheat is forbidden to be watered with wheat yellow water; Pay close attention to the weather forecast when pouring slurry, and do not water before the rainstorm to avoid lodging.

There is still one month before the wheat is harvested from the filling stage to the yellow maturity (around June 10, and around June 5, the wheat will be harvested along the Yangtze River). If there is a slight drought during the wheat filling period, there is no need to water it. In order to obtain high yield of wheat, the traditional understanding is to multicast seedlings and apply more fertilizers to improve the natural yield of wheat seedlings, which is similar to the fattening of white feather chickens now. However, if we consider the index of 1000-grain weight, it is actually not a high yield.

If there is no rain, or the rainfall is not up to standard, the field is dry and the wheat in the field is not growing well, water it in time at this time to promote wheat production. Don't worry about wheat lodging after watering. Wheat varieties with strong drought resistance and water saving ability can be planted without watering. High quality and strong gluten wheat varieties can improve grain quality without irrigation. However, it has a certain effect on improving irrigation yield of conventional varieties. After flowering and heading, wheat will enter the filling stage, with swollen ears and full grains. At this time, it is the peak water demand of wheat, and the water supply of wheat is sufficient at the filling stage (the field water capacity of wheat is 70-80%).

Generally, water for grouting should be used when there is no wind on a sunny day in the early stage of grouting, so that it can be poured quickly when there is no wind and stopped when there is wind. Pay close attention to the weather changes, avoid watering before the storm and prevent lodging. Now in May, when wheat enters the flowering and filling stage, it needs to be watered in time, which directly affects the grain plumpness and yield of wheat (spraying pesticides to remove midges and aphids).
