Problems solved by technology

[0003] However, the grafting survival rate of black olives is far lower than that of green olives. In general, the grafting survival rate of black olives is about 40%. Therefore, it is urgent to study a method to improve the grafting survival rate of black olive fruit trees.

Embodiment 1

[0030] A method for improving the survival rate of black olive fruit tree high-graft replacement, comprising the following steps:

[0031] (1) Moderate shortening and truncation: the black olive fruit trees aged 15-25 years in the orchard are moderately shortened and truncated, the height of the tree is appropriately reduced, and the strong and evenly distributed main branches are retained to facilitate rejuvenation;

[0032] (2) High grafting and planting replacement: During the period of severe cold to rain every year, select the full branches of high-quality black olive fruit trees with full buds as scions, and use the embedded grafting method to graft black olive fruit trees. The diameter of the interface is 5-10cm, and each plant is grafted. 8-12 ears; after grafting, the scion, interface and main branch are evenly wrapped with transparent film, and the ungrafted branches are sawed off along the bottom of the branches;

[0033] (3) Tree wrapping: wrap the whole tree with ...

Embodiment 2

[0039] The experimental group data of table 1 is the growth condition investigation data of the black olive fruit tree after the inventive method is processed; Olive fruit tree growth survey data.

[0040] Table 1 Experimental group data

[0041]

[0042] Table 2 Data of the control group

[0043]

[0044] Note: The investigation time was one and a half years after the black olive fruit trees were treated with high grafting and replanting.

[0045] It can be seen from the above table that the survival rate of grafting of black olive fruit trees treated by tree body wrapping method increased by 53.8% compared with those without treatment, the average yield per plant increased by 2.7kg, and the yield growth rate was 117%.

Embodiment 3

[0047] The data of the experimental group in Table 3 is the survey data of the growth status of the black olive fruit tree after being moderately shortened and truncated.

[0048] Table 3 Experimental group data

[0049]

[0050] Table 4 Data of the control group

[0051]

[0052] Note: The investigation time was one and a half years after the black olive fruit trees were treated with moderate shrinkage and truncation.

[0053] As can be seen from the above table, there are black olive fruit trees treated with moderate shrinkage and truncation than those without treatment, the length of new shoots has increased by 83cm, and the yield has increased by 5kg. Although the black olive fruit trees built without moderate shortening and truncation can survive through tree wrapping and high grafting, their growth is not ideal.

Abstract

The invention relates to the technical field of fruit tree cultivation and discloses a method for improving the survival rate of top grafting variety change for black olive trees. The method comprisesfollowing steps: (1) moderate cutting: lowering the trees and keeping main branches which are strong and uniformly distributed; (2) top grafting variety changing: selecting full branches of high-quality black olive trees with plump bud eyes as scions, using the notch grafting method and bundling the scions, the interface and the main branches with transparent thin film after grafting; (3) tree bundling: bundling the whole tree with opaque films at positions 1.5m above the port facing wind. According to the invention, the moderate cutting method is adopted to lower the black olive trees and increase the fruiting rate; at the same time, the black olive trees can be recovered in a short time to promote the quick growth of scions and form fruiting crowns; by means of the top grafting varietychanging method, the black olive of poor variety and low economic benefit are changed into black olive trees having high economic benefit; the bundling of trees is aimed at moisturizing, protecting against cold and freezing, and ensuring the normal supply of nutrients, which is good for bud eye germinating and shooting new branches, therefore increasing the survival rate of top grafting variety changing.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for improving the survival rate of black olive fruit trees after high grafting and replacement. Background technique [0002] Olives are divided into two types, table olives and oil olives, and table olives are divided into green olives and black olives. Black olive is an evergreen tree distributed in southern China and Vietnam, and often grows in low-altitude mountain forests. Black olive is known for its purple-black skin and pulp. Its fruit contains calcium and vitamin C. It is rich in nutrients and easily absorbed by the human body. It has extremely high medicinal and nutritional values. [0003] However, the grafting survival rate of black olives is far lower than that of green olives. In general, the grafting survival rate of black olives is about 40%, so it is urgent to study a method to improve the grafting survival rate of black olive fruit trees...
