Full-illumination mist cutting rapid propagation method for sympodial bamboo

Abstract

The invention discloses a full-illumination mist cutting rapid propagation method for sympodial bamboo, and relates to the technical field of propagation of the sympodial bamboo. The method comprisesthe following steps: preparation work; material selection; cutting pretreatment; cutting; mist spray management; transplanting to a field. During material selection, 1-2-year-old sympodial bamboo is selected as a stock plant, a cutting material is cut off from the stock plant and subjected to water retention and cutting work timely, a mist spray device is started after cutting, and the cutting material is enabled to have sufficient water in the whole propagation process. Through the adoption of the full-illumination mist cutting rapid propagation method for the sympodial bamboo, most leaves onthe cutting material can be retained, photosynthesis of the leaves is promoted by natural light, endogenous hormone is produced to stimulate bamboo rhizomes to root, so that the cutting material grows more robust, a high-temperature and high-humidity environment is provided for the cutting material, the rooting speed of the cutting material can be increased obviously, and by cooperation with a culture medium, the problems that leaves of the cutting material of the sympodial bamboo are prone to falling off due to water loss, roots are prone to rotting due to water accumulation and the like canbe solved.

Description

technical field [0001] The invention relates to the technical field of clump bamboo propagation, in particular to a rapid propagation method of clump bamboo cuttings by full-illumination spraying. Background technique [0002] Bamboo is an important part of forest resources. It can be divided into two categories: clustered bamboo and scattered bamboo. Clustered bamboo has the characteristics of large shoot production, high yield, beautiful appearance, strong soil fixation and water retention capacity, etc., and its utilization value and The potential for ecological and economic development is huge, and it is the type of bamboo that is given priority in the development of bamboo shoots and wood dual-use forests in various places. [0003] Because the seeds of clustered bamboo are difficult to obtain, traditional clustered bamboo afforestation is mainly transplanted with poles, the cost of afforestation is high, and there is a risk of destroying the growth and shoot capacity o...

Problems solved by technology

Affected by the season, bamboo cuttings in summer (June-August) take root faster, and if the conditions are right, summer cuttings can be out of the nursery in 60-90 days; but because bamboo cuttings are relatively fragile in the early stage of growth, high temperature in summer is easy It will be sunburned or dehydrated. Therefore, in order to improve the survival rate, most of the leaves of the cutting branches need to be trimmed and strong shading measures are required. Although these measures can ensure the survival of the cuttings, they can inhibit the growth of the cuttings. effect, the greater the pruning intensity and the greater the shading intensity, the greater the inhibitory effect
