Problems solved by technology

However, for some tree species that are difficult to root from cuttings, or the cuttings lose water during the collection of branches for cutting seedlings, cutting cuttings and field cuttings, the problems of cutting callus rooting and low survival rate of cutting seedlings often occur, which affect the production of seedlings.
In the existing cutting seedling raising technology, in addition to the application of hormone rooting accelerators, there is a lack of other effective technical measures to improve the survival rate of cutting seedlings

Embodiment Construction

[0020] The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment:

[0021] The cutting treatment method for promoting the survival rate of woody plant cutting seedlings provided by the present invention is realized through the following steps:

[0022] 1) Rinse the cut cuttings in clean water, bundle them according to the biological direction, and put them forward in a closed washing pool;

[0023] 2) Close the washing tank and form a negative pressure state of -1 Pa, slowly inject the washing liquid into the washing tank, and keep the negative pressure constant, continue to rinse the root of the cuttings for 0.5-1.0h, and slowly increase the pressure in the washing tank after washing. pressure to normal atmospheric pressure;

[0024] 3) Take out the cuttings from the washing tank, put them into airtight plastic bags, and bring them into the field for cuttings.

[0025] As a preferred manner, the flushing solution is ...

Abstract

The invention discloses a cutting processing method and device for promoting the woody plant cutting seedling survival rate, and relates to the field of woody plant cutting seedling. The negative pressure principle is utilized, cuttings are continuously flushed through a cutting transfusion tissue by using flushing fluid with a certain concentration of sucrose, a certain concentration of citric acid and a certain ratio and concentration of rooting accelerant, embolism gas in cutting tissue is exhausted, rooting inhibiting substances (such as tannin) are washed off, the cutting tissue water content and the rooting hormone concentration level and nutrient content are improved, the cutting tissue callusing and rooting rate of woody plant cutting seedling is greatly reduced, and the cutting rooting rate and the seeding survival rate are improved by 30%-50%. The method is simple, convenient and easy to perform; the whole device is good in working stability, high in efficiency, low in cost and capable of being used continuously in the long term, and has good economic benefits.

Description

technical field [0001] The invention relates to the field of cutting seedling raising of woody plants, in particular to a cutting treatment method and device for promoting the survival rate of cutting seedling raising of woody plants. Background technique [0002] Cutting seedlings can not only maintain the excellent genetic traits of the parents, but also has low cost and is easy to reproduce rapidly on a large scale. It is the main way of raising seedlings of woody plants. However, for some tree species that are difficult to root from cuttings, or the cuttings lose water during the collection of branches for cutting seedlings, cutting cuttings and field cuttings, the problems of cutting callus rooting are difficult and the survival rate of cutting seedlings is low, which affects the production of seedlings. In the existing cutting seedling raising technology, in addition to the application of hormone rooting accelerators, there is a lack of other effective technical measur...
