How to do boron deficiency in cotton fields
At present, some cotton fields suffer from boron deficiency. When cotton is deficient in boron, it will cause small and small flowers and poor flower opening. It is prone to flowers but not bells. There are few bells, and the bell is light and has a sharp hook shape. The serious shortage of boron in the cotton field highlights the veins, the leaves become brittle, the leaves are shrinking, and the curling is reversed, which affects the yield and quality of the cotton.
In order to avoid boron deficiency in the cotton field, the following measures should be taken: In the base fertilizer, there is no plot of boron fertilizer, and the combination of flower and bell fertilizer should be used to make up 200-250 g of boron per mu. During the period of boll-lining, the abundance of boron solution was sprayed on the foliar surface of the cotton, and it was sprayed evenly before 9 o'clock in the morning or at 4 o'clock in the afternoon on sunny days. The application of 0.3%-0.5% urea was better when applied.
