Micro-graft and fast propagation method of tree

Abstract

The invention relates to a rapid tree micrografting propagation method. The method comprises the following steps: (1) selecting two tree twigs with good affinity or twigs of the current year on a tree as rootstocks and scions respectively; (2) respectively performing sterilization treatment on the rootstocks and the scions; (3) respectively performing hormone treatment on the rootstocks and the scions; (4) grafting the rootstocks and the scions in the way of scion grafting or bud grafting; (5) cultivating grafted seedlings in a sand bed; (6) removing rootstock shoots in time; and (7) removing binding plastics after the scion survives and young sprouts grow to 20-30cm, thus completing rapid micrografting propagation of the rootstocks and the scions. The method applies the modern biotechnologies to fine variety breeding, realizes industrial large-scale seedling culture, and the method can be implemented in protected areas all the year round. Compared with the existing grafting seedling culture methods, the propagation method has the advantages of low cost, fast seedling formation, robust growth of nursery stocks and easy transplantation, and can rapidly propagate to obtain great amount of new species of good nursery stocks in a short time.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a rapid propagation method for forest tree micro-body grafting. Background technique [0002] my country's agricultural production has changed from single-family operation to professional household and company operation, and agricultural production has changed from traditional scattered and disorderly development to orderly and planned development in accordance with local conditions. With the continuous development of the industry, the traditional seedling cultivation methods of self-fertilization, self-propagation, and self-retention can no longer meet the needs of current industrialization and large-scale development. In the process of seedling cultivation, some transgenic varieties with high-quality characteristics have the problem that they cannot form seeds or have few seeds, which makes the price particularly expensive. It is difficult to meet the needs of large-s...

Problems solved by technology

At present, it is necessary to select a suitable rootstock variety before grafting seedlings, that is, to cultivate rootstock seedlings. It takes 1 to 2 years to cultivate, and fast-growing varieties also need about half a year. The multiplication cycle of seedlings increases the production cost, such as: salinity-resistant poplar, jujube seedlings, chestnut seedlings, red bayberry, loquat, etc., all need to spend a long time in cultivation to become a commercial seedling that can grow and be available

Moreover, the conventional grafting seedling raising method also has many technological processes, a long seedling raising cycle, and the survival rate of seedlings is greatly affected by the shortcomings of the weather.
