Problems solved by technology

However, the time for cuttings of twigs is limited to May and June of each year. During this period, the temperature is high and the climate is humid, which can easily cause the callus of twigs to rot, lose water and wilt, and the survival rate is low; and the root cutting technology is difficult to take roots. And it will cause damage to the roots of the mother tree, which in turn will affect its healthy growth
In addition, bactericides such as carbendazim used in the cutting process are likely to pose potential threats to the human body and the environment

Embodiment 1

[0016] A method for propagating hardwood cuttages of pine plums, carried out according to the following steps:

[0017] (1) Prepare the cutting seedbed: the seedbed is set in the greenhouse, the bottom of the seedbed is laid with 10cm thick washed building stones, and the upper part is laid with yellow sand and vermiculite with a volume ratio of 2:1, the width is 25cm, and the length is 6m , and then carry out disinfection and sterilization with the wood vinegar with a concentration of 1v%;

[0018] (2) Preparation of root promoting agent: add 0.01v% wood vinegar to 750ppm indole butyric acid solution;

[0019] (3) Preparation of cuttings: In late February, select annual branches that grow robustly and are free from diseases and insect pests, collect them with a length of about 25-35 cm, wrap them in wet newspaper and place them in a cool place, cut off the tips of the branches, and cut the lower part of the branches into 10 Cuttings with a length of ~15cm, cut the lower end ...

Abstract

The invention discloses a prunus maritima marshall hard branch cutting propagation method, which is carried out according to the following six steps that (1) a cutting seedbed is prepared; (2) root growth promoting agents are prepared; (3) cutting branches are prepared; (4) cutting is carried out; (5) post-cutting management is implemented; (6) domestication is carried out. When being adopted, the method disclosed by the invention avoids the problems of easy germ contamination decay, water loss wilting, low survival rate and the like of cutting slip callus caused by summer cutting, in addition, the damage to parent bodies of the prunus maritima marshall and the potential contamination risk in the cutting process are reduced, the cost is low, the management is simple, and the popularization is easy.

Description

technical field [0001] The invention belongs to the technical field of plant vegetative propagation, and in particular relates to a method for cutting and propagating hardwoods of japonica. Background technique [0002] Prunus maritima Marshall (Prunus maritima Marshall) belongs to the genus Prunus in the Rosaceae family. It is a salt-tolerant fruit tree native to the North Atlantic coast of the northeastern United States. Limeberry has the characteristics of drought resistance and salt-alkali resistance, and can adapt to the harsh conditions of the seashore. It plays a very important role in the ecological restoration and soil and water conservation of coastal tidal flats; and its sweet and sour fruits, many flowers and beautiful appearance, have a relatively High economic and landscape value. At present, the introduction and cultivation of pine plums in China have been successful. Cutting technology has become an important way of large-scale breeding of Limeberry because...
