A kind of one-step cultivation method of camellia oleifera seedling stock light substrate grafted container seedling

Abstract

The present invention relates to the technical field of plant seedling breeding, in particular to a one-step cultivation method for Camellia oleifera bud-stock light matrix grafting container seedlings. The method comprises seedbed preparation, seedling transplantation and incubation management after seedling transplantation. The seedbed preparation comprises the steps of shadow sprinkler system construction, seedbed establishment, overall disinfection, nutrition frame placement and matrix disinfection, the seedling transplantation comprises the steps of sludge preparation, matrix treatment, seedling transplantation, spraying disinfection, rodenticide placement and film covering, and the incubation management after seedling transplantation comprises the steps of complementation and moisture retention, spraying cooling, film-peeling protection, and film and shadow net removal. The present invention aims to provide a one-step cultivation method for Camellia oleifera bud-stock light matrix grafting container seedlings, the conventional method is changed, and a centralized and refined management process is adopted, so that the graft survival rate and seedling growth speed are improved, and then the afforestation efficiency is improved, and the economic effect is increased.

Description

technical field [0001] The invention relates to the technical field of plant seedling propagation, in particular to a one-step cultivation method for camellia oleifera bud seedling anvil grafted container seedling with light substrate. Background technique [0002] Camellia oleifera is a unique high-grade woody edible oil tree species in my country, and is known as the world's four largest woody oil tree species together with olive, oil palm and coconut. In order to ensure the national grain and oil security, in recent years, the whole country has set off a climax of vigorously developing the camellia oleifera industry. However, due to the restriction of seedling quality, the survival rate of Camellia oleifera afforestation in that year was not ideal, resulting in aggravated replanting tasks and increased difficulty in management and protection. Low enough to lose confidence and give up management and protection, the helpless dilemma from losing confidence and giving up man...

Problems solved by technology

In recent years, there has been no research in this area abroad. In China, the Subtropical Forestry Experimental Center of the Chinese Academy of Forestry in Jiangxi, Tianfeng Huamuchang in Ningwei Town, Xiaoshan, Hangzhou, and Hubei Academy of Forestry, etc. Bud seedling anvil grafting container seedling one-step cultivation method" has been studied, but the effect is very poor, there are two main problems: one is that the survival rate of grafting is very low, only 10-20%; the other is that the growth is poor, although some units put The survival rate of grafting has increased to about 70%, but the average height of one-year-old seedlings is only about 3 cm, and a considerable part of them have not grown new shoots

This method of cultivating seedlings in a harsh environment of long-term, high temperature, high humidity and closed anoxic environment is an unprecedented challenge. The existing cultivation methods are relatively traditional and extensive, with few method innovations and no intensification and refined management procedures, resulting in defects such as low graft survival rate and slow growth of seedlings
