Description

A kind of hydroponic self-circulation cultivation system for bamboo seedlings

technical field

The invention relates to the technical field of bamboo cultivation, in particular to a hydroponic self-circulation cultivation system for bamboo seedlings.

Background technique

The bamboo propagation method in my country has mainly relied on the transplanting of mother bamboo for thousands of years. The reproduction efficiency is low and the cost is high, resulting in forest land destruction and soil erosion, which greatly limits the cultivation of bamboo resources and industrial development. With the rapid development of my country's bamboo industry, the demand for high-quality bamboo seedlings is becoming more and more vigorous. The demand for high-efficiency breeding techniques and devices for high-quality bamboo seedlings is becoming more and more urgent in industrial development.

Bamboo seedlings have the characteristics of strong stress resistance and low cost, and are mostly used in scientific research and production work such as bamboo breeding and variety improvement. The existing bamboo seedling cultivation method adopts the mixed cultivation method of solid substrate and nutrient soil, the seed bag cultivation method, and there is no systematic hydroponic method. Using the solid substrate method for cultivation, in the process of root material collection and drug treatment, there are often deficiencies such as damage to young roots, residual culture substrate, and inaccurate control of drug action concentration and time. The seed bag method is limited to the treatment and observation of the roots of seedlings, and there are shortcomings such as a small amount of cultivation in a single bag, poor air permeability of the roots, growth retardation, and one-time use.
