Abstract

The invention relates to the technical field of plant grafting cultivation, in particular to a walnut seedling grafting propagation method. According to the walnut seedling grafting propagation method, a culture solution is prepared from, by weight, 3-5 parts of ethyl alcohol, 2-3 parts of sodium hypochlorite, 3-5 parts of streptomycin, 3-5 parts of gibberellic acid, 4-6 parts of brassinolide, 3-5 parts of 2,3-dichlorphenoxyacetic acid, 3-5 parts of N-(3-chloro-4-pyridyl)-N'-phenylurea, 2-3 parts of rosin, 4-6 parts of jasmonic acid, 4-6 parts of salicylic acid, 3-5 parts of rooting powder and 2-3 parts of water-retaining agent, and then the propagation steps of stock and scion preparation, disinfection, grafting, soaking and the like are carried out. The walnut seedling grafting propagation method is scientific and reasonable in formula, the walnut seedling wound healing time can be shortened, growth can be promoted, and the grafting survival rate can be increased.

Description

technical field [0001] The invention relates to the technical field of plant grafting and cultivation, in particular to a method for grafting and breeding walnut seedlings. Background technique [0002] Plant grafting is carried out by utilizing the wound healing function of plants, and is an important plant propagation technique. During grafting, the cambiums of the two injured surfaces are brought closer and tied together, and as a result, due to cell proliferation, they heal each other and become a whole connected by vascular tissues. This is the principle of grafting. Plant grafting is of great significance to the reproduction of some fruit trees that do not produce seeds (such as some varieties of persimmon and citrus). It can not only maintain the excellent traits of scion varieties, but also use the favorable characteristics of rootstocks to achieve early results, enhance cold resistance, and drought resistance. It can also economically utilize propagation materials ...
