Kiwi fruit tree low-location grafting method

Abstract

The invention discloses a kiwi fruit tree low-location grafting method and relates to the field of kiwi planting. The method includes the steps of (1), cutting stock, to be specific, cutting or sawingthe stock to be grafted or connected, or the trunk of the original variety, at the smooth and strain position which is 5-10cm above the ground; (2), splitting the stock; (3), cutting scion, to be specific, selecting buds with full and plump tissue, remaining protective piles 1-2cm in length above the buds, cutting to form wedges which are 2-3cm in length and have smooth and straight two sides; (4), inserting the scion; (5), earthing; (6), final-period management. The kiwi fruit tree low-location grafting method is applied to grafting of kiwi fruit trees in the period of dormancy, is easy to operate, and can reduce influence from bleeding and low temperature in winter and increase grafting survival rate; the grafted plants grow strong, shape rapidly and can enter the full bearing period far ahead, particularly, after graftage, in the second year, the yield of the big trees can be equal to and even higher than 40% of that in the full bearing period under management level of standard orchards.

Description

technical field [0001] The invention relates to the field of kiwifruit planting, in particular to a low-level grafting method of kiwifruit. Background technique [0002] Kiwi fruit is rich in nutrition and is known as the king of fruits and the king of vitamin C. At present, the national kiwifruit planting area is only about 3 million mu, of which the standard base is less than 300,000 mu, which is far from the nearly 40 million mu of citrus, apple, grape and other planting scales. There are many varieties of kiwifruit planted in my country, and the planting areas are widely distributed. In recent years, as consumers have become more aware of kiwifruit, its development momentum has been rapid, and it has become a leader among the third-generation fruits after the first and second-generation fruits such as citrus, apples, and grapes. At the same time, kiwifruit is more suitable for large-scale industrial development than third-generation fruits such as strawberries and blue...

Problems solved by technology

The traditional grafting method is high from the ground, and is tied with a grafting film. Often due to spring injury, the bandaging film is filled with tree sap, which affects the survival of the grafting joint.

Especially in the case of low temperature in winter and unstable spring temperature in mountainous areas in the north, the grafting method that can really do a good job and has a high survival rate has not.
