Problems solved by technology

[0002] At present, pecans are grafted with 2-3-year-old seedlings cultivated from seeds, and the grafting survival rate is low, which cannot meet the requirements of popularization and utilization in production. Therefore, there is no large-scale promotion of pecans in production. Afforestation of variety seedlings has affected the process of hickory varieties and the promotion of intensive management
Some grafted with Huaxiang or maple poplar as rootstock, a small amount can survive, but it is not up to the extent that it can be popularized and used in production

Embodiment Construction

[0021] The present invention will be further described below in conjunction with embodiment: but the content of the present invention is not limited thereto.

[0022] Carya different stock grafting method of the present invention, mainly comprises the steps:

[0023] 1. Collect hickory variety spikes 2 in advance from December to January, and store them under low-temperature and moisturizing conditions of 1-4°C. Thin-shell hickory rootstocks should be seeded before January, and the root system should be trimmed. Seedlings with a ground diameter of 0.6 cm or more can be used as root stocks, and transplanted according to the row spacing of 0.15×0.25 cm. After transplanting, cut the stems at a height of 30 cm.

[0024] 2. Cover the plastic greenhouse before February, the height of the shed is greater than 1.8m, and the width of the shed is greater than 5m, which is beneficial for people to work in the shed. In mid-to-late March, when the average daily temperature is greater than...

Abstract

The hetero stock grafting process for pecan includes adopting thin-shell pecan stock and common pecan scion, raising the soil temperature for the stock to over 10 deg.c and cleft grafting. The present invention has the positive effects of raised grafting survival rate and capacity of providing high quality pecan tree.

Description

technical field [0001] The invention relates to the asexual propagation technique of hickory, and mainly relates to a method for grafting hickory with different stock. Background technique [0002] At present, pecans are grafted with 2-3-year-old seedlings cultivated from seeds, and the grafting survival rate is low, which cannot meet the requirements of popularization and utilization in production. Therefore, there is no large-scale promotion of pecans in production. Variety seedling afforestation has affected the process of hickory varieties and the promotion of intensive management. Some grafts that use Huaxiang or maple poplar as rootstocks can survive in a small amount, but they are not up to the extent that they can be popularized and used in production. Contents of the invention [0003] The present invention aims to solve the above-mentioned defects in the prior art, and provides a method for grafting hickory different anvils that can improve the grafting survival...
