Flue-cured tobacco seedling culture matrix and seedling culture method adopting same

Abstract

The invention provides a flue-cured tobacco seedling culture matrix which comprises sawdust, corn straw particles, pearl powder and chitosan. The invention further provides a seedling culture method adopting the matrix. The method includes: (1), decomposing and disinfecting; (2), dishing and seeding; (3), performing water management; (4), performing temperature, humidity and nutrient management; (5), hardening seedlings. The matrix and the method have the advantages that the flue-cured tobacco seedling culture matrix which is low in cost and can use local materials is researched to replace a flue-cured tobacco conventional seedling culture matrix-turf; the seedling culture method for guiding flue-cured tobacco production and being high in root system activity, short in seedling recovery period and high in survival rate and stress resistance (especially drought resistance) is researched and formed, and a foundation is laid for development of flue-cured tobacco industry.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation methods, in particular to a flue-cured tobacco seedling raising substrate and a seedling raising method using the substrate. Background technique [0002] In the 1990s, it was labor-intensive and time-consuming to raise seedlings with nutrition bags, and it was impossible to carry out large-scale intensive production and eliminate soil-borne diseases. In recent years, due to the large-scale promotion of conventional seedling raising substrate peat flue-cured tobacco floating seedlings, although soil-borne diseases have been eliminated, it is conducive to uniform transplanting time, consistent maturity of tobacco leaves, centralized baking and purchase, but the cost of seedling cultivation is high, and the root system of the tobacco seedlings raised The vitality is weak, the seedling period is long, the survival rate is low, and the stress resistance is poor (especially drought resistanc...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the defects of high seedling cost and poor biological performance of tobacco seedlings caused by using peat as the main component of the substrate to cultivate flue-cured tobacco seedlings in the prior art, the present invention provides a flue-cured tobacco seedling raising substrate and a seedling raising method using the substrate to realize The purpose of this study is to develop a low-cost flue-cured tobacco seedling substrate that can be obtained locally to replace the conventional flue-cured tobacco seedling substrate peat; at the same time, to study the formation of flue-cured tobacco production with strong root activity, short seedling period, high survival rate, and strong stress resistance (especially It is a seedling raising method with strong drought resistance, which lays the foundation for the development of flue-cured tobacco industry
