Immature leaf mulberry leaves are immature, with more water content, less dry matter, more organic acids, used to feed silkworms, which will make silkworms malnourished, weak constitution, easy to induce pus and softening disease.
The weather of drought-affected leaves is long and dry, the water and nutrients of mulberry leaves are reduced, and the amount of cellulose is increased. This mulberry leaf is difficult to meet the growth needs of the silkworm body, which will significantly reduce the blood water content of the silkworm body and cause silkworm disease.
The water content of the old leaves of mulberry leaves is below 70%, and the hand-crushed people are aged leaves. The old hard-shelled silkworms are not easy to eat and difficult to digest. The silkworms are slow to grow and lose weight due to lack of nutrition.
The water loss rate of wilted leaf mulberry leaves in transport and storage is 10%-20%, and the food consumption of wilting leaves will be significantly reduced, resulting in slow development.
The mulberry leaves in which the pests and diseases are infested by pests and diseases are accompanied by various pathogens, which may cause the silkworms to become sick and reduce the yield of silkworm cocoons.
