Winter management techniques of mulberry trees with double bumper harvest of fruits and leaves

Fruit mulberry tree

From winter to early spring, reasonable pruning and pruning of fruit mulberry trees will greatly increase the fruit mulberry yield and mulberry leaves in the second year, and obtain higher economic benefits.

Pruning is to cut off the unsubstantial xylem at the top of the branch after the natural defoliation of the mulberry tree. Pruning can reduce nutrient consumption, enrich branches, enhance cold resistance, increase the germination rate and fruit setting rate of mulberry in spring, and increase the yield of spring leaves and summer fruit.

The main results are as follows: 1. During the period of pruning, mulberry trees did not stop growing a little too early. When the temperature rose, the winter buds in the middle and upper parts of the branches grew in autumn, but consumed nutrients; too late pruning, due to respiratory consumption, nutrients in the branches have been lost, reducing the pruning effect. The suitable period should be from the natural defoliation of mulberry in November to the early spring period.

2. Pruning length: the pruning length depends on mulberry variety and branch length. For the varieties with short branches, dense internodes and high germination rate, the shoots should be short, on the contrary, the shoots should be long. Generally, if the length of the branch is more than 1.5m, the length of the branch is more than 1.5m, the length of the branch is 1.3m, the length of the branch is 1.3m, the length of the branch is about 1.5m, the length of the branch is more than 1.5m, the length of the branch is 1.3m, the branch of 5m is cut, and the part of the unlignified part is subtracted from about lm.

3. Pay attention to the problem: keep the cutting bud when cutting the tip, cut it at the lcm above the cutting bud and cut it into a horseshoe-shaped bevel. The top cut should be picked out and burned in time, which can kill some diseases and insect pests.

Fruit mulberry pruning is to use mulberry shears or saws to trim mulberry trees, to plug holes in mulberry trees with lime, and so on. Winter pruning can reduce unnecessary nutrient consumption, eliminate diseases and insect pests, enhance the tree potential, make the tree shape neat, and facilitate random shaping in the future.

The pruning of fruit mulberry in winter can be carried out after mulberry leaves fall, after pruning and before sap flow in early spring. This period is the dormant period of mulberry, which has little effect on mulberry physiology; at the same time, it is also the period when diseases and insect pests are latent in the trunk, which can reduce diseases and insect pests. When pruning, the tool should be cut close to the trunk, and the cut should be smooth, do not hurt healthy branches, do not split, which is conducive to wound healing and latent bud germination. The pruned branches of diseases and insect pests should be cleared out of the mulberry garden to completely eliminate the source of diseases and insect pests.
