A kind of plant leaf bud year-round tender branch cutting propagation method

Abstract

The invention relates to a method for plant leaf bud shoot cutting propagation all year around and relates to the technical field of vegetative propagation. The method aims to overcome the defects that in the prior art, nursery stock seedling propagation is large in variation and part of nursery stock is low in maturing rate, and tissue culture propagation is high in cost and difficult in technology management, and minimum stems of existing fine seed nursery stock leaf buds are adopted as female parent cuttage materials for cuttage. The method includes the steps of solar greenhouse or movable greenhouse facility and planting bed preparation, leaf bud selection, cuttage time and method determination and seedling period management. The propagation coefficient of seedlings cultivated in the method can be progressively increased in a multiplied mode, the survival rate of the seedlings can reach 90%, roots are developed and grow vigorously, and the transplantation survival rate can exceed 95%. The method has the greatest advantages that mass production and industrialized production can be achieved, propagation does not need professionals, and the method is easy to operate, low in individual cost, high in propagated seedling survival rate and easy to popularize.

Description

technical field [0001] The invention relates to the technical field of plant vegetative propagation, in particular to a method for cutting and propagating plant leaf buds throughout the year with twigs. Background technique [0002] The current plant propagation methods are mainly tissue culture, seed propagation, hardwood cuttings, and green branch cuttings; these several propagation methods have their own advantages and disadvantages. Tissue culture requires a lot of capital investment, high technical requirements, and is not easy to popularize. The offspring of seed breeding has a large variation range and cannot maintain the characteristics of good varieties; hardwood cuttings propagate once a year. The reproduction coefficient is low, and the tissue is aging, so it is not easy to take root. At present, green branch cuttings are the most cost-effective but need one-year-old mature branches, which are propagated in a specific period of time, such as June-August every year...

AI Technical Summary

Problems solved by technology

Tissue culture requires a lot of capital investment, high technical requirements, and is not easy to popularize. The offspring of seed breeding has a large variation range, and the characteristics of excellent varieties cannot be maintained; hardwood cuttings propagate once a year. The reproduction coefficient is low, and the tissue is aging, so it is not easy to take root

At present, green branch cuttings are the most cost-effective but need one-year-old mature branches, which are propagated in a specific period of time, such as June-August every year, and are easy to rot in the substrate, and cannot achieve mass production, factory production, and year-round production; these propagation The method limits the popularization of newly developed excellent plant varieties and emerging precious plants, prolongs the time to market, and the annual production volume of low-cost propagation of professional nursery units; under this background, through experimental research, a plant with full leaf buds has been developed. The annual young shoot cutting propagation method, which is between tissue cultivation and green branch cutting propagation, not only breaks through the high cost of tissue cultivation, high technical difficulty, and sterile conditions, but also breaks through the green branch cutting that cannot be produced in a factory throughout the year and consumables Large, especially for rare plants with rare provenances, they can reproduce rapidly, with annual production and high reproduction coefficient. In theory, one leaf, one axillary bud and one seedling; the method is simple, less investment, easy to operate, and high survival rate
