Seedling growing method of apocarya

Abstract

The invention relates to a seedling growing method of apocarya and belongs to the technical field of fruit trees and forest cultivation. The method includes the steps of sprouting breeding, grafting and post-grafting management. By means of the method, a large amount of scions are obtained each year and are grafted on the stock and the seedling with strong affinity in due time, so that stock grafting survival rate of the apocarya is improved. Grafted seedling preserving rate after large-amount grafting is over 90%. Further, the method achieves tree body stuntedness, shortens the juvenile phase and enables tree bodies to fruit earlier in the fourth year after grafting. The fruiting time is 6-8 years earlier than before. Simultaneously, the method provides a growing method for apocarya stock grafting seedlings and with strong operability for batch and variety seedling growing of the apocarya and greatly increases economical value of the apocarya.

Description

Technical field [0001] The invention belongs to the technical field of fruit tree and forest tree cultivation, and specifically relates to a seedling cultivation method for thin-shelled pecan. Background technique [0002] Thin-shelled pecans, also known as American pecans, are a species in the Juglans family and the genus Hickory. Native to the United States and Mexico, it is one of the most important oil-bearing dried fruit tree species in the world. Its shell is thin and easy to peel, its kernels are thick and delicious, and it has high nutritional value. With straight trunks, beautiful tree shapes, deep and lush roots, it is an excellent tree species for greening and gardening. At the same time, the wood is tough and dense, the heartwood is dark red, the sapwood is yellow and white, elastic, not easy to be deformed and cracked, and is an excellent timber species for construction and high-end furniture. Therefore, the hickory pecan is an excellent economic tree species with ...

Problems solved by technology

However, whether it is spring sowing or autumn sowing, it is difficult for annual seedlings to reach the level of grafting, and the growth is slow.

In order to make the thin-shelled pecans embark on the process of improving varieties and building bases as soon as possible, while accelerating germination and cultivating improved varieties, we started to tackle key problems in rootstock grafting technology. However, due to the low survival rate of grafting, the supply of grafted seedlings was in short supply. However, the seedlings have defects such as late production, small nuts, and poor adaptability, and are not popular in the market. Therefore, there are two key factors restricting the development of production. One is the lack of sufficient seedlings of good varieties, and the other is the lack of scientific systems. cultivation techniques

[0004] The applicant has been engaged in the work of planting a large amount of pecan seedlings for many years, and has focused on asexual propagation experiments such as cuttings and grafting of pecan, but the reproduction coefficient is low, and the quality of seedlings is uneven. Asexual reproduction technology is still in the experimental stage, and a mature method that can be widely promoted and repeatedly verified has not yet been formed.
