Incubation method of open-centralized shape mulberry

Abstract

The invention relates to a high-yield culture method for an open-center type mulberry. The method comprises the following steps: fixing a stem for a cultured nursery stock in a first spring; carrying out the summer cutting for the twigs growing on a first stem; after the summer cutting, carrying out the autumn cutting for the twigs growing on the first stem so as to form a second stem; breeding silkworms through the twigs cut from the top of the second stem; and carrying out the cycle. Through the summer cutting for the twigs on the first stem in the second year, the method prolongs the spring growing period of the mulberry and brings about an additional silkworm spring rearing season. Through the autumn cutting for the twigs after the summer cutting in the same year, the culture period is reduced from three years to two years. A plurality of twigs are forked from the top of the second stem, so that the method increases the number of the twigs and improves the yield. The method changes a traditional mode of picking mulberry leaves and adopts mulberry twig harvest to replace the leaf collection, thereby improving the mulberry leaf yield and reducing the workload of mulberry leaf collection. The method has the advantages of saving time and labor, reducing cost and increasing benefits, along with short culture period, high leaf yield and good silkworm breeding effects; therefore, the method deserves generalization.

Description

technical field [0001] The invention relates to a method for cultivating mulberry trees, in particular to a method for cultivating high-yield happy-shaped mulberry trees. Background technique [0002] The low-dry mulberry growing method is the most widely used method for cultivating a high-yield mulberry tree type in current planting. In this method, the planted seedlings are fixed in the first year, the branches growing on the main trunk are cut in spring in the second year, and the branches growing in the third year are cut in summer, so that the mulberry trees cultivated in cycles grow. More vigorous, suitable for close planting. However, the cultivation cycle is long and the growth of mulberry trees is relatively high, so it is difficult to improve the yield and quality of mulberry leaves, which increases the difficulty of management in mulberry gardens and reduces the control effect of mulberry tree diseases and insect pests. Especially mulberry leaves need to be coll...

AI Technical Summary

Problems solved by technology

However, the cultivation cycle is long and the growth of mulberry trees is relatively high, so it is difficult to improve the yield and quality of mulberry leaves, which increases the difficulty of management in mulberry gardens and reduces the control effect of mulberry tree diseases and insect pests.

In particular, mulberry leaves need to be collected manually, which not only increases the labor intensity and labor cost, but also easily withers after collection, which directly affects the quality of mulberry leaves and the benefits of silkworm rearing.
