Mulberry can be planted from December to March of the following year. According to the survey, the mulberry winter planting root system is in closer contact with the soil, which is conducive to the improvement of the planting survival rate. After the spring temperature rises, the mulberry tree grows quickly and grows well. The mulberry planting technology is briefly introduced as follows. Careful planning, conscientious planning before planting and planting mulberry, to ensure contiguous planting, avoid mixing grain mulberry, reduce pesticide pollution, ensure silkworm for safety. Reasonable planning is conducive to the establishment of high-yielding and stable production of mulberry gardens and improvement of the economic benefits of sericulture; it is conducive to the establishment of sericultural specialty villages and professional groups to form a scale effect. Distinguish, classify the implementation of the aging mulberry garden with a tree age of 15 years or more, should adopt the method of digging the old or new planting or updating the plant; the low-yielding mulberry garden with a younger age but less dense density should be encrypted. The way of replanting was changed to ensure that there were more than 1,000 mulberry plants per acre. The patchwork mulberry field must be filled in and filled out of the mulberry groves to exclude the silkworm as a safety hazard. Variety selection adhere to the main promotion of 71-1 breeding, multi-type collocation strategy. Yu 71-1 mulberry has the advantages of erect branches, dense internodes, large leaves, thick leaves, high leaf yield, and superior leaf quality. According to the survey, under the same site conditions, the amount of leaves produced per mu per mu is about 30% higher than that of the old variety Husang 32. The disadvantage of this variety is that the mulberry varieties with relatively weak resistance to mulberry disease and higher incidence of mulberry disease should be selected. Planting requires about 1200 plants per acre, usually planted in rows, with a spacing of 1.3 meters and a plant spacing of 40 to 50 centimeters; it can also be planted in wide and narrow rows, with a 1.6 meter wide row spacing and a small row spacing of 1 meter. Dig flat land before planting to improve soil properties to facilitate the growth of new mulberry roots. The planting ditch is excavated according to the predetermined spacing, and the basal fertilizer is applied. The loose soil in the ditch is required, and both ends are connected to the drainage ditch to prevent accumulation of water. Before planting, do a good job of seedling selection, remove bad seedlings, classify and plant, and prevent mixed planting. The roots of the seedlings may be trimmed to a length that is not more than 20 cm in length. When planting must pull the fixed point, so that the line is neat, the same depth, root stretch, when the soil to the edge of the seedlings should be light to raise the seedlings, so that the soil and root system tightly combined, and finally practicable soil, pouring enough water. The soil should be slightly higher than the ground to prevent freezing and drought.
