Water and fertilizer management is very important after wheat turns green in spring. What should be done in spring wheat planting?

With the temperature rising gradually, winter wheat in many areas has entered the rapid growth period of returning to green and jointing. How to do well the first water and fertilizer management of wheat in spring and the key points of field management at the jointing stage of wheat turning green are the problems that farmers should pay attention to at present.

Below, Bian Xiao will share some experiences of wheat and spring wheat management around these two issues for farmers' reference. How to manage the spring wheat field in wheat planting? When did the first obesity begin? For winter wheat, the key point of wheat field management is to maintain soil moisture and promote the early stable growth of wheat seedlings. In the actual production process, many growers may find that some wheat seedlings have abnormal seedling conditions, such as hard seedlings, old seedlings, yellow seedlings and prosperous seedlings. Of course, before managing according to local conditions, farmers need to be clear about these seedlings, which specifically reflects the growth of wheat seedlings.

Strict seedlings. The growth of wheat seedlings is stagnant, staying in a certain growth period for a long time, and not tillering or rooting. Old Miao. When wheat seedlings grow to a certain number of leaves and tillers, there will be slow growth, short leaves and uncoordinated tiller elongation. Yellow seedlings. Lack of soil nutrients or insufficient soil moisture leads to yellowing of wheat seedling leaves. Prosperous Miao people. Excess or imbalance of soil nutrients leads to vigorous growth of wheat. Generally speaking, there are two reasons for these common abnormal seedling conditions. On the one hand, soil hardening leads to the deterioration of air permeability and fertility; On the other hand, it is caused by improper fertilization and water management in spring. Therefore, the following measures can be taken in spring wheat field management: using the top rake pressure of wheat seedlings to maintain soil moisture and improve soil properties; Rational management of fertilizer and water. In fertilizer moisture management, it involves when to apply fertilizer for the first time and how to apply fertilizer.

Now, let's discuss this problem in detail. Spring fertilization and water management of wheat mainly coordinate the relationship between nutrient growth and reproductive growth of wheat seedlings, especially the first fertilization and water management in spring. However, the specific work needs to be done according to different types of wheat fields. Generally speaking, there is one kind in the wheat field, that is, strong seedlings. In order to "control" the first fertilization, it should be postponed until the jointing stage of wheat. There are two kinds of wheat fields, usually seedlings. In order to promote and control the combination, the first fertilization should be carried out from wheat field to jointing stage; For areas with severe drought, it is appropriate to advance to the period of turning green to rising, and rationally adjust the wheat population structure.
