Harvest and cultivation management method for white mulberry strips and leaf all the year

Abstract

The invention discloses a method for harvesting and cultivating mulberry strip leaves in the whole year. Proper mature mulberry leaves on new shoots are harvested when silkworms are 1-3 years old; shootlets, and three blades are harvested when the silkworms are 3-4 years old; the new shoot leaves are harvested when the spring silkworms are 5 years old; after the shoots are cut, the operations of worm controlling, weeding and fertilizing for the mulberry are carried out; mulberry shoots are harvested in the mid-July in summer; namely, summer silkworms are raised since last third of June, and the disbudding leaves are harvested by combining with the mulberry disbudding when the summer silkworms are 3-4 years old in the first third of July; 2 / 3-1 / 2 of the shoot intermediate cuttings on the mulberry are picked during middle third of July; meanwhile, 15-25cm of the remained mulberry shoot boots are remained and others are harvested by cutting; meanwhile, 10-15kg of pure nitrogen fertilizeris fertilized for each mu area; when later autumn silkworms are raised in October, the strip leaves on the shoots budding in autumn are harvested; detailedly, 15-25cm of roots are remained and othersare picked. The method of the invention can improve the labor intensity and sufficiently exert the productivity of the mulberry field.

Description

Technical field: [0001] The invention relates to a method for cultivating tubes of mulberry leaves. Background technique: [0002] Mulberry tree cutting is generally divided into two types: spring cutting and summer cutting. In order to increase the yield of mulberry leaves and facilitate the management of mulberry gardens, summer cutting is often used to form mulberry trees into a certain tree shape. Mulberry leaf harvesting is generally divided into leaf harvesting. Both are harvested with strip leaves. In order to prevent the decline of tree vigor and increase the yield of mulberry leaves, in the middle and later stages of silkworm production, the method of harvesting new shoots and cutting leaves in late autumn is generally used. Leaf harvesting is generally used, especially in late autumn combined with winter cuttings of mulberry trees. Strip leaves, often due to the phenomenon of germination of visceral buds in "October Xiaoyangchun", sometimes affect the vigor of mul...

Problems solved by technology

In order to prevent the decline of tree vigor and increase the yield of mulberry leaves, in the middle and later stages of silkworm production, the method of harvesting new shoots and cutting leaves in late autumn is generally used. Leaf harvesting is generally used, especially in late autumn combined with winter cuttings of mulberry trees. Strip leaves, often because of the phenomenon of "October Xiaoyangchun" that the internal buds germinate, sometimes affect the vigor of the mulberry tree and affect the mulberry leaf output of the mulberry garden in the next spring

At the same time, because harvesting leaves is time-consuming and labor-intensive, it affects labor production efficiency
