Problems solved by technology

[0007] The reasons for the low survival rate of mango high-branch grafting mainly include the following points: First, the affinity between the rootstock variety and the scion variety is not enough, and there is not enough water and nutrient exchange between the rootstock incision and the scion incision, and sufficient healing cannot be formed. The second is that after the rootstock is cut off the crown during grafting, the transpiration is weakened, and the water and nutrients transported to the incision of the rootstock are insufficient. At this time, if watering is easy to splash on the grafting interface, the survival rate of grafting will be greatly reduced. If it is not watered, the survival rate of grafting will be reduced due to the lack of moisture and nutrients at the incision of the rootstock; third, in order to prevent microbial infection, the scion often needs to be soaked or smeared with sterilized liquid after it is cut, causing the scion to rot. The dormant bud points of the scion are damaged, and the medicinal liquid is easy to soak into the scion tissue from the incision at both ends of the scion, which affects the vigor of the scion, and then leads to a low survival rate of high-branch grafting; the fourth is the impact of environmental conditions, such as water ingress at the grafting port caused by external rainfall. , drastic changes in external temperature, etc., these will affect the survival rate of mango high-branch grafting
[0008] For mango high-branch grafting, especially the problem of low survival rate of mango high-branch grafting with low affinity between rootstock varieties and scion varieties, there is currently no reported technical means to overcome it, especially to overcome the problems that lead to this problem at the same time. The above four reasons of the problem, therefore, this technology needs to be developed

Abstract

The invention discloses a method for increasing mango high-branch grafting survival rate. The method includes the steps that a regulator I is sprayed to a scion tree body of a scion to be collected before collecting the scion; an annular ditch is dug around a rootstock tree body to be subjected to high-branch grafting before grafting, and a regulator II is applied in a burying mode; tree crowns are trimmed before grafting; during high branch grafting, after stock and scion incisions are cut, beta-1,3-1, and 4 glucanase solutions are dipped and smeared on the stock incisions and the scion incisions respectively, and then the scion incisions are connected with the stock incisions for grafting; and a regulator III is sprayed to the whole plant after grafting is completed. By the adoption of the method for increasing the mango high-branch grafting survival rate, the survival rate of mango high branch grafting is increased from 30-40% to 65-85% under the condition that the affinity degree between a stock variety and a scion variety is low, the basic healing speed of a grafting opening is increased by 10-15 days or above compared with a conventional method, new scion shoots do not need to be unbound after being drawn out, the surface of the grafting opening is smoother, and the probability of suffering from microbial diseases in a later period is reduced.

Description

technical field [0001] The invention relates to a method for improving the survival rate of mango high-branch grafting, in particular to a method for improving the survival rate of mango high-branch grafting under the condition that the affinity between rootstock varieties and scion varieties is low, and belongs to the technical field of plant cultivation . Background technique [0002] Mango is an important tropical fruit tree. Its fruit is beautiful in shape, bright in color and rich in aroma. It is widely loved by consumers and is known as the "king of tropical fruits". Although mango occupies an important position in tropical fruit trees, because it is a typical tropical crop, it is sensitive to temperature and can only be grown in tropical and subtropical regions. Due to the constraints of climatic conditions, the production area of ​​mango is relatively limited. Traditionally, most mangoes in my country are planted in front of and behind houses in rural areas in tropi...
