The risk of mulberry trees in spring is "mulberry looper" and "mulberry caterpillar". They mainly feed on Mulberry Shoots and young leaves.

The control method can be sprayed with dichlorvos solution of 1000 times in mulberry bud stage, mainly after artificial mulberry leaves after long night.

The two is fertilization.

Real time application of spring fertilizer can promote the development of sprout. The first spring fertilizer was applied in late March. The second spring fertilizer was applied in late April, and the amount of fertilizer should be 30% of the total annual fertilization.

Summer manure can ensure high yield of mulberry leaves all year round. The first summer fertilizer can be mixed with farmyard manure and chemical fertilizer. The second summer fertilizer is mainly based on quick acting nitrogen fertilizer.

Summer fertilizer application accounted for 50% of the annual fertilizer consumption.

Autumn fertilizer can promote the thriving branches and leaves, delay the hardening of autumn leaves and increase the yield of autumn leaves.

Autumn fertilizer should be applied immediately after leaf picking, mainly with quick acting fertilizers.

The method of "external root fertilization" sprays water-soluble fertilizers on mulberry leaves, and the leaf receives nutrients to increase mulberry leaf yield.

Fertilization outside the root is suitable for the early stage of the development of spring leaves. When the root system has not yet developed vigorously, it can not receive large amounts of fertilizer.
