Background
Mulberry leaf is the leaf of mulberry, and is the main food for silkworm. The whole mulberry leaf is about 15 cm long and about 10 cm wide, the stem is about 4 cm long, the basal part of the leaf is heart-shaped, the top of the leaf is slightly pointed, the edge of the leaf is provided with saw teeth, and the veins are dense and growing Bai Roumao; the old leaves are thicker and dark green, the tender leaves are thinner, the green and yellow leaves are crisp and easy to hold, and the flavor is light and bitter. The mulberry leaf not only has the effects of dispelling wind-heat, clearing lung-heat, moistening dryness, clearing liver and improving eyesight, but also has unique curative effects on treating common cold, lung-heat, dry cough, dizziness, headache and conjunctival congestion and dim eyesight. In recent years, the nutritional value of the bud heads of the mulberry leaves is more found to be rich, and the bud heads of the mulberry leaves are made into vegetables, so that the mulberry leaves have the value of food therapy and are popular.
China is a large country for planting mulberries, and agricultural families in China continuously and deeply study and obtain rich achievements in the aspects of breeding improved varieties of mulberries, fertilizer for mulberries, control of mulberries diseases and insect pests, management of mulberry gardens and the like, and currently, more than thousand mulberry varieties are collected, tidied and newly bred. For example, zhejiang and Jiangsu have two mulberry species groups of lake mulberry and fire mulberry, the lake mulberry is thick and long in general branches, large in leaf shape, slow in hardening and strong in adaptability, and most of the lake mulberry belongs to medium and late growth species; the mulberry leaves with red Pi Huosang and Bai Pihuo are purple, and the young leaves of the mulberry leaves are all early-growing varieties. In addition, sichuan has Jiading mulberry leaves of Chuannan Leshan, the branches are long, and the quality of She Xishe is good; the branches of the Guangdong mulberry are fine and straight, and the skin is grey. Shandong has Lu mulberry, and the branches are thick, short, dense, early in hardening and cold-resistant. At present, china has greatly developed in the aspect of mulberry planting, but for mulberry picking, as a special leaf harvester for the mulberry leaves is not available at present, the mulberry leaves in China still need to be picked manually by a mulberry farmer, so that the labor intensity of the mulberry farmer is extremely high and the working efficiency is extremely low.
