If pruning is needed, pruning mulberry trees from winter to early spring will greatly increase the output of mulberry trees and mulberry leaves in the next year; Softwood cutting is to cut off the incomplete xylem at the top of the branch after the mulberry leaves fall off naturally; Cutting twigs can reduce nutrient consumption, enrich branches, enhance cold resistance, improve the germination rate and fruit setting rate of mulberry in the next spring, and increase the yield of spring leaves and Xia Guo.

cultivation techniques

Mulberries are generally planted in places with good drainage system, flat ground, sufficient sunshine and ventilation. Choose sandy soil, deeply plough the nursery 15 ~ 30 cm, and choose urea or compound fertilizer as the base fertilizer of the nursery.

The suitable planting temperature is 28 ~ 30℃, and the rooting time is 65438+1mid-October-165438+1mid-October and early April-June. Mulberry has strong adaptability to soil and has the characteristics of barren resistance, drought resistance and waterlogging resistance. Common propagation methods include cutting, layering, grafting and seed propagation? [5-6]。

1, layered

Press down the branches from the mother plant, cut off the bark of the branches and bury them in the soil, leaving the branches exposed. When the branch survives and takes root, cut it off. Generally, it is planted in spring or autumn, and the mother plant is buried in the ditch and compacted in early spring. Row spacing and plant spacing are 2.0 m× 0.4 m.

2. Transplantation method

Grafting is to graft the bud or branch of another mulberry tree to the root or branch of a mulberry tree to make it a new plant. Grafting methods mainly include root grafting, branch grafting and bud grafting. Temperature has a direct effect on the grafting effect. Therefore, according to the characteristics of tree species, we must choose the appropriate grafting period, generally 20 ~ 25℃, and do not graft in windy conditions and rainy season.
