Problems solved by technology

[0003] Over the years, Guangxi has never solved the problem of mulberry seedling cultivation. As a kind of fruit, mulberries are more and more popular among consumers. At the same time, mulberry trees are also seedlings needed for planting mulberry trees. The cost is high, and the mulberry seedlings are easy to lose water, resulting in a low survival rate after planting. At the same time, some quarantine mulberry pests and diseases are brought in. In order to get rid of this passive situation, we are now vigorously developing the cultivation of grafted seedlings. 5 million plants, according to statistics, the survival rate of some plots and some planting rows is as high as 90% or more, and the survival rate of some planting is less than 30%. In the spring of 2010, self-cultivation and self-grafting were adopted. 5000 plants, the average survival rate of planting is 65%

Embodiment 1

[0019] A method for grafting mulberry seedlings, comprising the following steps:

[0020] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0021] (2) select the scion: select bud fullness, fullness and completeness, no side branches, appropriate thickness bar as the scion on the fine-bred mulberry fringe branch without diseases and insects of clipping, 1 year old and strong; The kind of described scion is special Excellent 2;

[0022] (3) Grafting: Grafting is carried out in March every year, adopts bag grafting method, while scion is grafted to rootstock, smears grafting healing agent around the grafting joint, then binds the grafting joint with plastic film; The healing agent is prepared by mixing the following raw materials in parts by weight: 9 parts of rhubarb extract, 2 parts of saponin extract, and 4 parts of senecio extract; extracted with n-butanol at 70-80°C, filter...

Embodiment 2

[0024] A method for grafting mulberry seedlings, comprising the following steps:

[0025] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0026] (2) Select the scion: select the full-bodied, full, complete, no side branches, and appropriate thickness bar as the scion on the 1-year-old healthy mulberry fringe branch without disease and insects that are clipped; the kind of the scion is Cantonese Mulberry 11;

[0027] (3) Grafting: Grafting is carried out in January of each year, adopts bag grafting method, while scion is grafted to rootstock, smears grafting healing agent around the grafting joint, then binds the grafting joint with plastic film; The healing agent is prepared by mixing the following raw materials in parts by weight: 8 parts of rhubarb extract, 1 part of saponin extract, and 2 parts of senecio extract; extracted with n-butanol at 70-80°C, filtered, recovered n...

Embodiment 3

[0029] A method for grafting mulberry seedlings, comprising the following steps:

[0030] (1) select rootstock: select annual, ungrafted, adapt to local growth, and the mulberry seedlings whose rhizome is 0.5~0.7cm are used as rootstock;

[0031] (2) Select the scion: select the full-bodied, full, complete, no side branches, and appropriate thickness bar as the scion on the fine-bred mulberry fringe branch without disease and insects and 1-year-old robustness of clipping; the kind of the scion is osmanthus Sanyo 62;

[0032] (3) Grafting: Grafting is carried out in April every year, adopts bag grafting method, while scion is grafted to rootstock, smears grafting healing agent around the grafting joint, then binds the grafting joint with plastic film; The healing agent is prepared by mixing the following raw materials in parts by weight: 10 parts of rhubarb extract, 3 parts of saponin extract, and 6 parts of senecio extract; extracted with n-butanol at 70-80°C, filtered, reco...

Abstract

The invention relates to a method for grafting mulberry saplings, and belongs to the field of agricultural planting. The method for grafting the mulberry saplings includes steps of (1), selecting certain annual mulberry seedlings to be used as rootstock; (2), selecting certain solid and complete branches from shorn annual robust improved-variety mulberry cladus without diseases or pests and usingthe certain solid and complete branches as scions; (3), grafting the scions to the rootstock by the aid of bark grafting processes, simultaneously smearing grafting healing agents around grafting openings, and then binding the grafting openings by the aid of plastic films. The certain selected annual mulberry seedlings are not grafted and can adaptively locally grow, and the sizes of rhizomes of the selected annual mulberry seedlings range from 0.5 cm to 0.7 cm. The selected solid and complete branches to be used as the scions have plump buds and appropriate thicknesses and are free of lateralbranches. The method has the advantages that the survival rate of grafted mulberry sapling can be obviously increased by the aid of the method and can range from 90% to 96%, the sapling recovery periods can be effectively shortened, withering of nursery stock can be prevented, and growth of the mulberry saplings can be promoted.

Description

【Technical field】 [0001] The invention relates to the field of agricultural planting, in particular to a method for grafting mulberry seedlings. 【Background technique】 [0002] Grafting mulberry seedlings has the characteristics of a large number of seedlings per unit area and strong growth of mulberry seedlings after survival. It is a rapid seedling raising method and approach to meet the needs of large-scale planting. At present, the national project of "moving mulberries from east to west" is being implemented steadily. In the next few years, this project alone will require about 500 million mulberry seedlings every year. Therefore, identifying the factors that affect the survival of mulberry grafting and raising seedlings, and taking effective countermeasures will not only help improve the efficiency of seedling raising per unit area, but also help meet the needs of the national "Moving Mulberry from East to West" project, and steadily promote the smooth progress of the ...
