AI Technical Summary

Problems solved by technology

The traditional high-splicing head-changing technology is not effective on kiwifruit trees over 5 years old, mainly reflected in the poor aging and renewal ability of the main vine branches, poor disease resistance, and weak growth, resulting in poor ability to draw new branches and move the resulting parts outward.
[0004] The existing grafting technology cannot solve the problems of poor disease resistance and weak growth of wild white kiwifruit after grafting, and the fruit of kiwifruit obtained by grafting is relatively small, which cannot meet the needs of the market

Embodiment 1

[0019] A kind of grafting method of kiwifruit tree, comprises the following steps:

[0020] 1) Rootstock cultivation: From the end of November to mid-December of the first year, the trunk of the red-heart kiwifruit tree older than 4 years is sawed to a height of 10 cm from the ground. The height from the ground is 100cm, and the middle position of the top surface of the sawn trunk is obliquely cut to form a W-shaped incision, and the rootstock is obtained, and the repair liquid is sprayed on the incision; the repair liquid is composed of 400mg / L naphthaleneacetic acid, 30mg / L A solution composed of L prochloraz, 170mg / L root powder and 40mg / L indole acetic acid.

[0021] 2) Scion treatment: When the highest temperature reaches 25-30°C, select the mature green branches of the current year as the scion from the strong wild white kiwifruit tree. The diameter of the scion is not greater than the diameter of the rootstock, and the scion is cut into a length of 15 cm. Leave 3 full ...

Abstract

The invention provides a kiwi fruit tree grafting method. The method comprises the following steps that a trunk of a red-centred kiwi fruit tree with the tree age larger than four is sawn off, when the tree grows to the middle of the second year, the trunk is sawn to reach the height of 100-120 cm, a scion is selected from a robust wild actinidia eriantha tree for grafting, and a cut is bound finally; the cut of the red-centred kiwi fruit tree serving as a stock is treated with repairing liquid, and a scion branch is soaked in a plant growth regulator. According to the method, the grafting survival rate is high, grafted kiwi fruits are enlarged, and the character is stable.

Description

technical field [0001] The invention belongs to the technical field of fruit tree grafting, and in particular relates to a method for grafting kiwifruit trees. Background technique [0002] Because kiwi fruit is rich in nutrition and high in vitamin content, its medicinal value and economic value are incomparable to other fruits. Therefore, the market capacity is large and there are broad development prospects. According to analysis, every 100g of kiwi fruit contains 150mg-420mg of vitamin C, which is 5-10 times higher than that of citrus, and 20-30 times higher than that of apples and pears. At the same time, kiwi fruit also contains 18 kinds of amino acids necessary for the human body and various mineral elements such as Ca, K, Fe, and Zn. According to the analysis of nutrition experts, if each person eats one kiwi fruit a day, the human body's needs for vitamins can be met. [0003] Among the existing kiwifruit cultivation techniques, the "kiwifruit cultivation techniq...
