Cutting and grafting integrated method for oil-tea trees

Abstract

The invention relates to the technical field of plant propagation and specifically relates to a cutting and grafting integrated method for oil-tea trees. The method comprises the following steps: taking branches of wild oil-tea variety or non-high-quality oil-tea variety for cutting; pulling the cut branches out of a seedbed after the cut branches form callus tissues; taking the cut branches as stock for grafting with the branches of high-quality oil-tea variety; transferring the cut branches into a transplanting matrix in a nutrition pot for daily managing. According to the method, the seedlings can be cultivated in large scale, the cultivation is not limited by the seasons and the problem of insufficient high-quality oil-tea variety resource can be solved. The seedling cultivation period is short; the survival rate of grafting is 85% or above; the use ratio of cuttage nursery land is high; a batch of cutting seedlings with callus tissues formed can be produced per month; a base fertilizer is fully applied to the seedbed, so that the turning over and base fertilizer application are only required after 3-4 batches of cutting seedlings are produced; the seedlings can be uninterruptedly produced in the whole year; the survived grafted oil-tea seedlings have the advantages of developed root system, excellent growth, plump leaves and no pest and disease damage.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of plant propagation, and in particular relates to an integrated method of camellia oleifera cutting and grafting. [0003] 【Background technique】 [0004] Camellia oleifera is an important edible oil tree species unique to my country. It has strong adaptability, drought resistance and barrenness, and is suitable for planting in southern hilly areas. The unsaturated fatty acid content of camellia oil reaches 94%, which is the highest among natural vegetable oils. It is a high-quality functional health care oil and a pure natural green edible oil. [0005] Camellia oleifera is propagated by seeds, cuttings or grafting. Propagation of seedlings with seeds requires a large number of good varieties of Camellia oleifera seeds, and the seedling period is long, which cannot meet the needs of the market, and the propagated seedlings cannot guarantee to maintain the excellent traits of the parents, and the t...

[0006] However, the above-mentioned propagation method of cutting first and then grafting has a long seedling raising period. After the cutting branches survive, the seedlings need to be continued for 2-3 months. Grafting can only be carried out when the root system of the cutting seedlings is mature and stable, and the extracted new shoots begin to lignify; otherwise When grafting, the cutting seedlings are used as the rootstock. When the grafting interface is cut, the cutting seedlings may be pulled out of the seedbed in severe cases, and the root system of the cutting seedlings may be damaged in light cases, and even all the roots are torn off; even in these cases None of them happened, and it will take 1.5-2 months after grafting, before the grafted scion can survive, and it will take a longer time to raise seedlings until the seedlings emerge

Therefore, a piece of nursery land can only produce 2 batches of Camellia oleifera seedlings a year, which is far from meeting the market's demand for high-quality varieties of Camellia oleifera seedlings
