Carya illinoensis large-root stock grafting method

Abstract

The invention discloses a carya illinoensis large-root stock grafting method. According to different sizes of root stocks and different grafting positions, different watering methods are adopted; the carya illinoensis large-root stock grafting method adopts bark cuttage and tongue grafting; and managements after grafting, such as bud picking, sprout removal, belt untying, water-preventing post erection and the like, are performed in time, so that the survival rate of carya illinoensis large-root stock grafted seedlings is improved.

Description

technical field [0001] The invention relates to a grafting technique, in particular to a method for grafting large rootstocks of thin-shell hickory nuts with high grafting survival rate and good fruit quality. Background technique [0002] Thin-shelled hickory, also known as long hickory and American hickory, has a large fruit with a thin shell and rich nutrition. It is a world-renowned top ten fruit with high economic value and a promising market prospect. Thin-shell pecans are native to North America, mainly in the United States, and have been introduced in my country for nearly a hundred years. However, due to various reasons, the quantity of pecans with thin shells is still too small to enter the commodity market, and the market supply depends on imports. Jiande City, Zhejiang Province is one of the few cities (counties) that first introduced hickory nuts in China. It began to plant seedlings in 1952. The earliest grafted orchards were built from 1981 to 1983. The avera...

Problems solved by technology

However, due to the low survival rate of grafting, the supply of grafted seedlings is in short supply, and some thin-shell pecan bases had to plant seedlings first.

The seedlings are put into production late, the nuts are small, and the palatability is poor. They are not popular in the market and must be replaced with high-quality strains.

At the same time, some thin-shell hickory bases built in the early stage were not equipped with pollination trees or were improperly configured, resulting in poor pollination, severe flower and fruit drop, and could not be put into normal production. Some plants had to be replaced with pollination trees.
