Problems solved by technology

[0003] The traditional method of grafting mulberry trees is usually root grafting. The traditional root grafting is to connect the scion to the root of the seedling rootstock with a seedling age of about half a year to one year, then plant it in a nursery, and then transplant it after 4 months. The cultivation cycle Longer, and there is a problem of damage to the tap root of the mulberry tree during the transplanting process, thereby reducing the survival rate of the mulberry tree

Embodiment 1

[0031] The present invention provides a kind of method for rapid propagation of mulberry high position grafting, it comprises the following steps:

[0032] Step 1. Select mulberry saplings with a DBH of 2 cm as the rootstock; keep at least two branches on the main stem of the rootstock as grafted branches, cut each branch 1m above the ground into a smooth cut surface, and cut vertically downward from the edge of the cut surface to form grafting incision;

[0033] Wherein, the cultivation method of mulberry sapling comprises the following steps:

[0034] Step S1, select flat land, spray herbicides to remove weeds, turn the land 40cm deep, expose to the sun for 3 days, then level the soil surface, spray a layer of 0.1% potassium permanganate solution on the soil surface, and get the planting land. Standby; dig multiple 40cm*40cm planting holes in the planting ground, and the distance between any two planting holes is 3m*1m, and put 5kg of organic fertilizer in each planting hol...

Embodiment 2

[0041] The present invention provides a kind of method for rapid propagation of mulberry high position grafting, it comprises the following steps:

[0042] Step 1. Select mulberry saplings with a diameter at breast height of 4cm as the rootstock; keep at least two branches on the main stem of the rootstock as grafted branches, cut each branch 1.2m from the ground into a smooth cut surface, and cut vertically downward from the edge of the cut surface. Form grafting incision;

[0043] Wherein, the cultivation method of mulberry sapling comprises the following steps:

[0044] Step S1, select flat land, spray herbicides to remove weeds, turn the land 60cm deep, expose to the sun for 3 days, then level the soil surface, spray a layer of 0.5% potassium permanganate solution on the soil surface, and get the planting land Standby; dig multiple 40cm*40cm planting holes in the planting ground, and the distance between any two planting holes is 3m*1m, and put 10kg of organic fertilizer in...

Embodiment 3

[0051] The present invention provides a kind of method for rapid propagation of mulberry high position grafting, it comprises the following steps:

[0052] Step 1. Select mulberry saplings with a diameter at breast height of 3 cm as the rootstock; keep at least two branches on the main stem of the rootstock as grafted branches, cut each branch 1.1m from the ground into a smooth cut surface, and cut vertically downward from the edge of the cut surface. Form grafting incision;

[0053] Wherein, the cultivation method of mulberry sapling comprises the following steps:

[0054] Step S1, select flat land, spray herbicides to remove weeds, turn the land 50cm deep, expose to the sun for 3 days, then level the soil surface, spray a layer of 0.3% potassium permanganate solution on the soil surface, and get the planting land Standby; dig multiple 40cm*40cm planting holes in the planting ground, and the distance between any two planting holes is 3m*1m, and put 8kg of organic fertilizer ...

Abstract

The invention discloses a method for rapid propagation of mulberry high-level grafting, which comprises: step 1, selecting a rootstock, and cutting the grafting incision; step 2, selecting a scion, cutting it and placing it in a refrigerator for storage; step 3, inserting the scion Graft the incision, and bandage the grafted part; step 4, after the grafting is completed, remove the newly drawn sprouts on the rootstock in time in the later management to ensure that the scion is at the top. The invention directly grafts the treated scion to the rootstock seedling at a high position, saves the transplanting step, avoids damage to the taproot during the transplanting process, shortens the cultivation time, avoids the establishment of additional cultivation forests, and saves land resources.

Description

technical field [0001] The invention relates to the technical field of plant grafting. More specifically, the present invention relates to a method for rapid propagation of mulberry tree high-position grafting. Background technique [0002] The breeding of mulberry seedlings is the prerequisite for the development of sericulture production, and the high-quality mulberry seedlings are the basis for the high yield of mulberry gardens. Mulberry tree grafting is a technique for asexual reproduction of mulberry seedlings. Asexual reproduction is the continuation of the growth of the vegetative organs of the mother tree and can maintain the excellent properties of the mother tree. The key point of the technique is to use the branches or buds of one mulberry tree as scions and connect them to the branches, trunks or roots of another mulberry tree used as rootstock, and the rootstocks and scions will heal each other to form a new complete plant. [0003] The traditional method of ...
