A two-year-old Camellia oleifera seedling raising method with light substrate

Abstract

The present invention relates to the technical field of Camellia oleifera planting, in particular to a method for raising seedlings of two-year-old camellia oleifera with light substrates, including seed selection and pretreatment-sand storage-germination-acceleration-soil preparation-ear picking and grafting-planting-seedling management-replanting-density adjustment The first step is to move one of the two surviving plants into the empty bag when replanting, which improves the utilization rate of the nutrition bag. Compound bactericidal granules. The light-substrate seedling raising method of two-year-old camellia oleifera of the present invention increases the steps of replanting and density adjustment, improves the emergence rate per unit area to a certain extent, and the proportion of qualified seedlings reaches more than 95% after successful grafting, effectively improving the The emergence rate of seedlings and the survival rate of Camellia oleifera afforestation have saved the cost of seedling afforestation to a certain extent.

Description

technical field [0001] The invention relates to the technical field of Camellia oleifera planting, in particular to a method for raising seedlings of two-year-old camellia oleifera with a light substrate. Background technique [0002] Camellia oleifera is an evergreen small tree belonging to the family Theaceae. The camellia oil extracted from camellia oleifera seeds is clear in color, fragrant in taste, rich in nutrition, and durable in storage. In recent years, my country has vigorously developed the camellia oleifera industry. Camellia oleifera seedlings are the basis for the development of the camellia oleifera industry. Without high-quality seedlings, the success rate of camellia oleifera afforestation and industrial benefits cannot be guaranteed, which increases the investment cost and industrial risk of the camellia oleifera industry. At present, the camellia oleifera afforestation seedlings in my country are mainly biennial bare root or container seedlings, and the ...

Problems solved by technology

[0003] In the production of light matrix seedlings on the market, for convenience, they are grafted or cut and transplanted directly into a nutrition bag or a nutrition cup to produce two young matrix seedlings. However, due to factors such as density, overlord seedlings, and survival rate The proportion of qualified seedlings that can go out of the nursery is relatively low, and the qualified rate of seedlings out of the nursery is generally less than 80% of the survival rate of grafting or cuttings; and the phenomenon of well-developed taproots and underdeveloped fibrous roots of cultivated tea seedlings is also common, resulting in a low survival rate for afforestation. After the seedlings come out of the nursery, empty nutrition bags can be seen everywhere in the nursery, which not only pollutes the environment but also increases the cost of seedling cultivation
