First, the application of fertilizer, control and promote weak.
The early sowing period, the fertilizer and water are sufficient, and the overgrown rapeseed and wheat are sprayed with paclobutrazol to control the growth, promote growth and prevent freezing. For fields with insufficient basic seedlings, weak growth, and poor fertility conditions, pay attention to the application of fertilizer (mainly organic fertilizer). The application of wax fertilizer can not only increase nutrients, but also keep warm and freeze, and promote the normal growth of crops. Before the rapeseed, it is necessary to pick up the moss in time, and the field with the tendency of early moss should be topdressed in time. The amount of wax fertilizer can be customized according to local conditions.
Second, the application of boron fertilizer, prevention and control of rapeseed "flowers and not real" and wheat "light spike".
The soil of rapeseed and wheat growing areas in Hubei Province is generally deficient in boron, and the rational application of boron fertilizer can solve the phenomenon of “flowers and flowers†​​and “empty shells and bright ears†of rape. In the later stage of rapeseed and wheat, 50 grams of “speed-learn†per acre was used, and 60 kilograms of water was applied to spray between the leaves. In mid-to-late February and mid-March, the spray was again applied. At the same time, we should also do a good job of weeding and weeding and pest control.
Spring and winter will increase production
Autumn drought has caused adverse effects on autumn-sown crops in Jiangxi Province. In a considerable part of the region, the rapeseed was not ripe, some live seedlings died due to drought and water shortage, the transplanting time of transplanted seedlings was postponed, and the growth of wheat seedlings was not enough, and the standard of strong seedlings was not reached. In order to ensure the increase in yield and income of summer crops, it is very important to apply fertilizer in winter.
