First, it is necessary to apply the base fertilizer, mainly organic fertilizer and phosphorus and potassium fertilizer, which is essential for the harvest of wheat. Some wheat fields do not use organic fertilizer and rely on chemical fertilizers. This is unscientific. Although it can increase production, it is difficult to stabilize production in the dry years.
Second, proper application of nitrogen and phosphorus nutrition is necessary to promote wheat early tillering and cultivating strong seedlings. However, for wheat fields with high soil fertility levels, it is necessary to prevent "Qiuwang" caused by excessive nitrogen fertilizer. Adequate phosphorus nutrition at the seedling stage is conducive to the safe wintering of winter wheat, and plays an important role in preventing "small old seedlings".
Third, it is necessary to properly apply nitrogen fertilizer. The amount of nitrogen fertilizer and the application period should be determined according to the condition of the seedlings. For the weak seedlings with insufficient total stem number per acre and poor growth of the group, it should be followed early to apply green fertilizer, which is conducive to fighting for spring tillering. . Wang Miao, who has more tillers and excessive group structure, should postpone the application of nitrogen fertilizer, with emphasis on the application of jointed fertilizer.
