Pruning and pruning mulberry leaves from winter to early spring will greatly increase the yield of mulberry leaves and mulberry leaves in the next year.

Softwood cutting is to cut off the unfinished 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.

1. Cutting period: Mulberry was cut too early and did not stop growing. When the temperature rises, the winter buds of the middle and upper branches germinate in autumn, but they consume nutrients; It is too late to cut the shoots, because some nutrients in the branches have been lost due to respiratory consumption, which reduces the pruning effect. The suitable period should be from June 5438+065438+ 10 to early spring after mulberry leaves fall naturally.

2. Length of cutting tip: The length of cutting tip depends on mulberry variety and branch length. For varieties with short branches, dense internodes and high germination rate, pruning should be short, and vice versa. Generally, 1/3, 1.5m-5m branches with a length greater than 1/6 are cut off, and the non-lignified parts are subtracted from lm.

3. Note: When cutting the tip, leave the cut bud, cut it at the lcm above the cut bud, and cut it into a horseshoe-shaped inclined plane. The cut top should be picked out in time and burned, which can kill some pests and diseases.

Pruning mulberry trees means pruning the fibers on mulberry trees with mulberry scissors or saws and blocking the holes in the trees with lime. Pruning in winter can reduce unnecessary nutrient consumption, eliminate pests and diseases, enhance the tree potential, make the tree neat, and facilitate random shaping in the future.

Fruit mulberry can be pruned in winter after mulberry leaves fall, after pruning and before early spring sap flow. This period is the dormancy period of mulberry, which has little effect on mulberry physiology; At the same time, it is also the period with the most latent trunk of pests and diseases, which can reduce pests and diseases. When pruning, the tools should be close to the trunk scissors, and the cutting mouth should be smooth, without damaging the healthy branches and splitting, which is beneficial to wound healing and latent bud germination. Pruned branches of pests and diseases should be removed from mulberry fields and the source of pests and diseases should be completely eliminated.
