Knowledge Release: Cotton'S Top Dressing Strategy

:

Light, partial or no fertilizer application: when cotton enters the growth stage, the competition of nutrients between plants is intense.

When the basal fertilizer is sufficient and the emergence is uniform, the new high lipid film is used to protect the original nutrients from losing. The seedlings can be lightly applied or not applied. When the seedlings are tall, short, strong and weak, they should be partial applied to the dwarf and weak seedlings, and then the new high lipid membrane should be sprayed to improve the yield, effective interest rate, and promote the weak to strong, and achieve high yield.

Stable application of bud fertilizer: after the emergence of cotton, fruit branches begin to appear, and the amount of fertilizer needs to increase rapidly. We should properly apply nitrogen fertilizer and spray cotton Zhuang Ti Ling to supplement the deficiency of nutrients, so that the growth function of cotton tree can be pformed into reproductive function, so as to increase the fruit setting rate of cotton buds.

Heavy application

Top cover fertilizer should be applied: cover top fertilizer properly.

Combined with pest control, foliar spraying can be carried out, and adding 15 cotton liquid to every three kilograms of liquid can improve the quality of autumn peach cotton and effectively improve the quality and high yield of cotton.
