Grafting method for promoting high yield of walnut fruits

Abstract

The invention discloses a grafting method for achieving high yield of walnut fruits. The grafting method comprises the following steps: (1) preparing rootstocks, namely adopting fresh twigs with the length being more than 30cm of the walnut tree which is fruitless for ten years as rootstocks; (2) breeding and carrying out scion; (3) grafting; (4) transplanting; (5) fertilizing; and (6) pruning. The improved walnut produced by the grafting method for promoting high yield of walnut fruits has strong early bearing property, has the fruiting rate more than 60%, has the survival rate more than 95% after transplanting, and has high yield; the improved walnut is sowed and grafted in the same year and bears fruit in the second year, the single plant can bear fringy or string fruits, and the walnut tree is vigorous, has strong branching rate and can fruit in inwards-growing twigs.

Description

technical field [0001] The invention belongs to the technical field of grafting, and in particular relates to a grafting method for promoting high yield of walnut fruit. Background technique [0002] Walnut is an excellent perennial economic tree species. In recent years, with people's understanding of the nutritional value of walnut, the price of walnut has become higher and higher. There is an urgent need for a large number of high-quality and stable-yield walnut varieties in production. It is the best and fastest way to re-graft the seedling trees into fine varieties and cultivate and plant seedlings of good varieties. Due to the influence of wounded flow and tannin, walnut grafting is difficult and requires high technology, especially for fine walnut varieties. (Excellent product) Grafted seedlings are difficult to cultivate, and the survival rate of grafting is below 30%, which directly affects the development of the walnut industry.

[0002] Walnut is an excellent perennial economic tree species. In recent years, with people's understanding of the nutritional value of walnut, the price of walnut has become higher and higher. There is an urgent need for a large number of high-quality and stable-yield walnut varieties in production. It is the best and fastest way to re-graft the seedling trees into fine varieties and cultivate and plant seedlings of good varieties. Due to the influence of wounded flow and tannin, walnut grafting is difficult and requires high technology, especially for fine walnut varieties. (Excellent product) Grafted seedlings are difficult to cultivate, and the survival rate of grafting is below 30%, which directly affects the development of the walnut industry. The walnuts on the walnut trees that survive grafting generally all bear fruit on a single branch, and the chest branch does not bear fruit. They all sit on one fruit, and it is rare to sit on two fruits, resulting in low yield and high price of walnut trees
