Bud-stock grafting method for camellia oleifera abel green branch with leaves

Abstract

The invention discloses a bud-stock grafting method for a camellia oleifera abel green branch with leaves. According to the method, a half-lignified green branch which is selected as a scion is grafted onto a nutritional bag stock seedling. A method for raising the green branch seedling with leaves through bud-stock grafting comprises the following steps of: seeding in a sand bed, bedding out at the seedling stage, and transplanting a nutrient cultivation stock seedling, wherein a stock is a camellia oleifera abel seedling, so that the root system is developed, and the capacity of absorbing inorganic nutrients and water is strong; the lignification degree of the scion is low, and tissue cells are active, so that a callus is formed quickly; and the reserved leaves can perform photosynthesis to generate organic nutrients for healing a graft union, so that the grafting survival rate is high, and the survival rate of forestation on mountains is higher than that of bud-stock grafted seedlings. Therefore, by adopting a novel technology of clonal reproduction for grafting the half-lignified green branch with the leaves, the grafting survival rate is more than 90 percent, the height of an annual grafted seedling is higher than 40cm, the ground diameter of the annual grafted seedling is 0.4cm, the root system is developed, the survival rate of the afforestation on the mountains is high, and stock seedlings of all seedling ages can be grafted all the year round as long as the stock seedlings have half-lignified green branches. The bud-stock grafting method for the camellia oleifera abel green branch with the leaves is suitable for large-scale industrial seedling raising application and the like. By adopting the novel bud-stock grafting method, the technical problem of low survival rate of forestation planting by using the bud-stock grafted seedlings is solved.

Description

technical field [0001] The invention relates to the field of agricultural science and technology, in particular to a grafting method for camellia oleifera green branches with leaves. Background technique [0002] Camellia oleifera (Camellia oleifera Abe1), an evergreen small tree belonging to the family Theaceae (Theaceae) and the genus Camellia (Camellia L), is a unique woody edible oil tree species in my country. Oil plants, Chinese tallow tree, tung tree and walnut are called my country's four major woody oil plants. Camellia oil is clear in color, fragrant in taste, rich in nutrition, and durable in storage. It is a high-quality health-care edible oil, and can also be used as lubricating oil and anti-rust oil as industrial oil. It takes 8-10 years for seedling afforestation to bear fruit, 3-4 years for grafted seedlings to bear fruit, and 5-6 years for early fruit bearing. Hard branch grafting, the wood is brittle and hard, and it is difficult to survive grafting. Graf...

Problems solved by technology

Grafted seedlings are cultivated by grafting with bud-stock. Grafted seedlings with bud-stock grow slowly, have weak root system, low grafting interface, shallow penetration of root system into the soil, and low survival rate of planting seedlings in mountain afforestation. Moreover, grafting has very strict requirements on rootstock, and rootstock seedlings are old. The nutrient consumption in the cotyledons is high, and the survival rate of grafting is low; the seedlings of the rootstock are young, and the tissue is tender. During the process of taking anvil, washing the anvil, grafting, planting, etc., it is easy to damage the young buds and break the cotyledon petiole, which will affect the survival rate of grafting.
