Number of leaves left: In the area where the silkworm was cultivated during the first stage of the harvest, the leaves on the shoots were more when harvesting, and only the cutting was performed when the cutting was performed. The lower leaves could not be removed for the first time. Leaves trees on branches. In the second-stage autumn silkworm area, when the first-stage autumn silkworm picks leaves, it must be neat and the height should be as consistent as possible. After cutting, each shoot should have 2-3 leaves, and the end bud must have leaves. 3, the degree of stay: grow good long mulberry leaves, mulberry gardens with poor growth potential to stay short, generally leave 80-110 cm, such as clipping under the first bud when there is no mulberry leaf, can be appropriately increased cut height Make sure to leave the first bud under the cut after the leaves, while cutting off the horizontal branches, thin branches.
