Low-yield mulberry gardens are mainly caused by poor management, over-aged trees, messy trees, poor varieties, and excessive ponds. We should keep the mulberry trees growing vigorously according to the cause and targeted transformation.
In addition to the shortage of ponds, the number of acres of plants required to reach 1,800 plants, the lack of plants and ponds to be replanted, to use 2 years of hybrid mulberry seedlings to replant, because of strong roots, strong growth, easy to survive, to be grafted and improved after survival.
Variety structure and improved varieties can not be high-yield, good variety structure can not only meet the leaf nutrition of small silkworms, but also meet the needs of large silkworms with large leaves. The yield of acreage is the highest, and the varieties need to be compared and tested. .
The old tree is rejuvenated and the low-yield mulberry garden with poor management is to be rejuvenated. The method still uses saw pile buds.
In the construction of irrigated land, the mulberry trees are poor due to long-term waterlogging, and the mulberry leaves are yellow or dry, so that the mulberry gardens are low-yielding, it is necessary to dredge the ditches, dit the soil, and carry out the system construction of the mulberry fields. Carry out comprehensive management of gardens, roads and water.
For the mulberry gardens with poor soil quality, shallow soil layer and low organic matter content, and can not produce high yield, we should do long-term soil improvement work, re-apply farmyard manure, and vigorously plant green manure to gradually increase production.
It is forbidden to use excessive leaves, especially late autumn silkworms, to have more than 5 leaves for photosynthesis.
Using spring cutting, cultivating the tree potential, it is not appropriate to use the "two five" (spring shear) to cause the tree to decline.
The cultivated tree type is inflorescences with branches, short tree branches, and dysplastic invisible mulberry trees to be shaped, and the weak branches are removed, and the healthy branches are selected to be re-developed.
Adhere to the comprehensive prevention and control technical measures for mulberry pests and diseases.
