Second, proper application of nitrogen and phosphorus nutrition is necessary to promote the early delivery of wheat and cultivate strong seedlings. However, for wheat fields with high levels of soil fertility, it is necessary to prevent “Akihaw†due to excessive nitrogen fertilizer. Adequate phosphorus nutrition at the seedling stage is conducive to the safe wintering of winter wheat, and it also plays an important role in preventing “small old seedlingsâ€.
Third, we must apply topdressing nitrogen fertilizers. The amount of nitrogen fertilizer and the application period should be determined according to the seedling condition. For weak seedlings with insufficient total stem number per mu and poor population growth, the green seedlings should be applied as early as possible to help spring for tillering. For Wang Miao who has more delivery and over-population of the group structure, nitrogen fertilizer should be postponed, focusing on the application of joint fertilizer.
How to Fertilize Winter Wheat Growing Period
First, it is necessary to apply basic fertilizers, mainly organic fertilizers and phosphorus and potassium fertilizers, which are crucial for the harvest of wheat. Some wheat fields do not rely on organic fertilizers and rely on chemical fertilizers. This is unscientific, and although it can also increase production, it is difficult to stabilize production in drought years.
