Oil-tea camellia cuttage and grafting integrated seedling breeding method

Abstract

The invention relates to the technical field of oil-tea camellia seedling propagation, in particular to an oil-tea camellia cuttage and grafting integrated seedling breeding method. The method comprises the following steps of using a wild oil-tea camellia or non-high quality oil-tea camellia branch to cut; after the cuttage branch forms self-healing tissues, timely plugging the cuttage branch out of a seedling breeding matrix, using as a stock and a high-quality oil-tea camellia branch to graft, then cutting into the seedling breeding matrix in a nutrition pot, and performing routine management. The method has the advantages that the scaled production and seedling breeding can be realized, the limitation by seasons is avoided, the requirement on high-quality oil-tea camellia branch is greatly decreased, and the problem of insufficient resources of high-quality oil-tea camellia is solved; the seedling breeding cycle is short, the grafting success rate is higher than 85%, the continuous production and seedling breeding in the whole year can be realized, the transfer of seedling breeding yard is not needed, and the seedling can be bred in the nutrition pot until the grafting survival seedling is take out of the garden; the operation is simple, the learning is easy, the cost is low, the root of grafted survival oil-tea camellia seeding is developed, the growth condition is good, the leaf is thick, and the pests and insects are avoided.

Description

【Technical field】 [0001] The invention belongs to the technical field of Camellia oleifera seedling propagation, and in particular relates to an integrated seedling raising method of Camellia oleifera cutting and grafting. 【Background technique】 [0002] 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. [0003] 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...

Problems solved by technology

[0004] However, the above-mentioned propagation method of cutting first and then grafting has a long seedling raising cycle. 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 new buds drawn out 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
