A kind of method for grafting acacia sprouts and twigs

Abstract

The invention belongs to the technical field of tree grafting, and particularly relates to a Chinese honey locust bud seedling twig grafting method. The method comprises the steps that Chinese honey locust seeds are cultivated for budding, bud seedlings growing to the height ranging from 7 cm to 10 cm are stock, Chinese honey locust fine breed trees with the diameter ranging from 0.2 cm to 0.5 cm are used as annual half lignification robust twigs and used as scions after tender thorns and tender thin twig ends are removed,; a cleft grafting method is adopted for grafting and enabling the twigs to grow into a new plant. The experiment proves that the survival rate can reach 90%, the cost is reduced by 50%, the fine breed seedling cultivation age limit is shortened, seedling sowing, grafting and outplanting can be easily achieved in the same year, and the method can be developed to be a large-scale Chinese honey locust fine breed breeding method and has application and popularization value.

Description

technical field [0001] The invention belongs to the technical field of tree grafting, and in particular relates to a method for grafting twigs of acacia buds. Background technique [0002] Honey locust (GleditsiasinensisLam.), also known as honey locust tree, is one of the unique tree species of Hemataceae in my country. The root system of acacia is deep and wide, vigorous growth, high tree and large crown, strong adaptability; it has the characteristics of light-loving and slightly shade-tolerant, drought-resistant, water-saving, cold-resistant, nitrogen-fixing, and resistance to diseases and insect pests. It can grow normally even in clay or sandy soil environment. It is one of the excellent ecological tree species for building soil and water conservation forests and windbreak and sand-fixing forests. Eco-economic tree species obtained. [0003] Acacia is dioecious, and the female tree has a strong ability to form pods (apods). Acacia fruit is a natural raw material for...

Problems solved by technology

[0004] However, at present, honey locusts cultivated in various places basically use seedlings to build gardens, that is, seeds are collected from large fruiting trees for seedling cultivation. There are large differences in thorns, resistance, etc., which cannot guarantee the excellent traits such as concentration of thorns in maturity, good quality, high yield and stable yield.

In order to maintain the excellent characteristics of the fine varieties of acacia, conventional asexual propagation methods such as chip bud grafting, split grafting, and skin grafting are mostly adopted at present. However, in view of the many and hard thorns on the acacia branches, the existing acacia grafting methods have the disadvantage of slow grafting speed. , low survival rate, high cost and other defects, thus restricting the rapid propagation and mass promotion of the improved varieties of acacia
