Top grafting method for macadamia nut

Abstract

The invention discloses a top grafting method for macadamia nuts. Through cutting stems, grafting, and managing after grafting and other methods, top grafting is performed on grown-up low-yield macadamia nut trees. The method is simple in operation and low in production cost, and dwarfs tree forms. In spring and autumn, grafting survival rate is high. The method is suitable to be used for variety transformation of a low-yield macadamia nut orchard.

Description

technical field [0001] The invention belongs to the field of agricultural planting, and in particular relates to a method for plant high grafting and planting replacement. Background technique [0002] Macadamia is native to Australia. Its fruit is nutritious, crispy and delicious. It sells well in the market and has good economic benefits. It has become one of the emerging fruit trees in the world today. Tropical regions around the world have introduced varieties one after another, and the varieties used in production are all imported from abroad. The ecological environment of the trial planting area is very different from the place of origin, which makes the quality and output of macadamia nuts in my country lower than the place of origin, and the gap is very large. The commerciality and market price of macadamia nuts have been reduced, and the income of fruit farmers has been reduced. In order to improve the economic benefits of macadamia nut production, for macadamia nut...

Problems solved by technology

Tropical regions around the world have introduced varieties one after another, and the varieties used in production are all imported from abroad. The ecological environment of the trial planting area is very different from the place of origin, which makes the quality and output of macadamia nuts in my country lower than the place of origin, and the gap is very large. It reduces the commodity and market price of macadamia nuts, and reduces the income of fruit farmers

In order to improve the economic benefits of macadamia nut production, for macadamia nut varieties that are not suitable for local ecological conditions, low-quality and low-yield trees, and lack market competitiveness, some fruit farmers directly cut down low-yield trees and replant high-quality varieties. This method is costly and takes a long time to put into production. , Time-consuming and labor-intensive. At present, some fruit growers use sawing off the main side branches for high-level grafting. This method has the problem that the crown cannot be dwarfed.
