Mulberry Park's spring management focus is as follows:
The transformation of the low-yield mulberry gardens has seriously dampened the enthusiasm of the silkworm farmers in planting mulberry and silkworm sericulture because of the sluggish silk industry in the past few years. The existing mulberry gardens are old, overgrown with weeds, and have low yields of mulberry leaves. For this part of the mulberry garden that is almost abandoned, the mulberry garden should be immediately renewed and transformed. Digging out the old mulberry trees with old trees and few branches, timely replanting new saplings, or interplanting new and old mulberry trees, and adding organic fertilizers in time to increase the number of mulberry branches and increase the amount of leaf production.
Doing a good job of gullying and draining water in the mulberry field will not only cause the mulberry root to rot, but also cause the loss of mulberry fertilizer and increase of pathogens, which will seriously affect the normal growth of spring mulberry trees. Therefore, the silkworm farmer should open a good mulberry garden drainage ditch in the spring, with a ditch depth of about 30 centimeters, so that no water accumulates after the rain, and water will be found and eliminated in time.
Strengthen Fertility Management The mulberry spring fertilizer is generally applied 15 to 20 days before the spring silkworm leaf stage (the lunar convulsions to the vernal equinox). Spring fertilizer should be based on fast-acting nitrogen fertilizers. Normally, decomposed manure, livestock manure or urea can be used, but organic fertilizers can also be used in combination. About 1,000 kilograms of human and animal dung are applied per acre, and urea is generally 15-20 kilograms per acre. The fertilization is applied by ditching or acupuncture, and the soil is covered immediately after fertilization. About 15 days before silkworm leaves are used, the green manure is buried in a timely manner, combined with the application of green manure, and at the same time, the mulberry field weeding is done well.
