Quick reproduction method for parasitic depression bar improved variety mulberry

Abstract

The present invention relates to a method for quick propagation of good variety mulberry by adopling parasitical layerage. It is characterized by that said method includes the following steps: (1), cultivating seedling: under the condition of 4-38deg.C excavating groove, downwards bending the mulberry branch and placing the mulberry branch into the groove, applying fertilizer, covering the grooveby using loose soil and making the head of branch be upwards exposed from soil surface, making natural growth for 4-8 months so as to oblain the young tree whose branch embedded in the soil is rootedand the branch head exposed from soil is grown into the seedling; and (2), transplanting: cutting the branch, transplanting the young tree into another tree pit, applying fertilizer, covering the tree pit with loose soil and making natural growth.

Description

technical field [0001] The invention relates to a method for cultivating seedlings of mulberry trees, in particular to a method for rapidly propagating fine mulberry trees by parasitic layering. Background technique [0002] Mulberry is a characteristic planting for the development of agricultural economic production in my country, and it is also a economic crop that farmers have a fast source of income, high benefits, and farmers' favorite planting. In the prior art, there are two methods for seedling breeding and propagation of mulberry trees: cutting propagation technology, seedling seedling propagation and grafting technology. Cutting is to use the regeneration function of plants to cut off a part of the vegetative organs and place them under suitable conditions to make the parasitic roots grow leaves. However, most of the existing mulberry varieties have a low cutting survival rate under natural conditions. It is also limited by the local environment; for example: the ...

Cutting is to use the regeneration function of plants to cut off a part of the vegetative organs and place them under suitable conditions to make the parasitic roots grow leaves. However, most of the existing mulberry varieties have a low cutting survival rate under natural conditions. It is also limited by the local environment; for example: the cuttings should be inserted in an electric heating hotbed, solar hotbed or spraying seedbed to heat up and accelerate the root to significantly improve the effect of root stimulation; also need to use auxin agents, generally NAA indole is commonly used Butyric acid (IBA) and indole butyric acid (IAA) were prepared at 20-500PPM and soaked for 24 hours before rooting and cutting. Pay attention to maintaining the temperature at all times. It can be transplanted after a few months, and it can grow to about 1 year after one year. Mi Gao, this method requires high technical requirements and large investment. Farmers often find it complicated and difficult to accept, and they are afraid of drought and waterlogging.

Seed breeding and reproduction requires attention to the collection of mulberry seeds, the identification of the quality of mulberry seeds, and the storage of mulberry seeds before sowing; in China, seeds are usually used to breed seedlings and then grafted into good mulberry trees. This method has been used since ancient times. The traditional habit of raising seedlings; the current method of raising seedlings adopts cube seedlings and egg-packed seedlings: cube seedlings need a lot of manpower to mix the soil into a ball, then level it into a seedbed shape, and then use a knife to divide the mud ball into one-inch squares, and then Level each square, sow the seeds and cover the seeds with sand; it takes more labor to raise the seedlings in eggs, and the soil and the lumps are separated into small egg shapes, and then each egg shape Sow the seeds, put them in the shape of a seedbed, cover the seeds with sand, and cover the seedbed with a film. After a few days or more than ten days, small saplings will emerge, and they will be transferred to the ground after several months of management. It can only grow about 1 meter high in a year, and a small amount of mulberry leaves can be picked in autumn. After two to three years of growth, the whole stem will be cut off, and then grafted to become a good mulberry. This method requires a lot of manpower, material resources and economic funds. Bears fruit and develops slowly
