Cultivation method for American pecan grafted seedlings

Abstract

The invention discloses a cultivation method for American pecan grafted seedlings. The method includes the following steps that a nursery based on wood walnut rootstock is built and sowed, and seedling cultivation is carried out by means of degradable cloth bags; a cutting orchard is built, wood walnuts serve as rootstock, and fruiting branches of grown trees of American pecans are used as scions; walnut seedlings grow downwards, and principal roots penetrate out of the cloth bags by 2-3 cm and are cut off; nursery stock is transplanted in winter, and it is required that the cloth bags and soil are integrally transplanted. After the wood walnut seedlings grow into trees basically, grafting modification is carried out on fruit trees through the fruiting branches of grown trees of American pecans; redundant branches which grafting modification is not conducted on are removed. According to the method, the grafted seedlings can be cultivated, and the time when the high yield period of the American pecans is reached is shortened to 3-5 years from original 10-12 years after grafting is carried out.

Description

technical field [0001] The invention relates to a method for cultivating grafted seedlings of fruit trees, in particular to a method for cultivating grafted seedlings of American walnut. Background technique [0002] The advantages of wood walnut are that the tree grows fast, has strong resistance to diseases and insect pests, and has a short tree-forming time. The disadvantage is that the fruit quality is poor, and the fruit setting rate is low in areas with low altitude and high humidity. The fruit-bearing and high-yield period of American long hickory seedlings is generally 10-12 years, and the fruit-bearing period of American long hickory grafted seedlings is 4-5 years, but the yield is very low. Contents of the invention [0003] The technical problem to be solved by the invention is to shorten the growth and fruiting time period of American pecan walnuts, and improve the walnut output and production benefits. [0004] For realizing above-mentioned object, the techn...
