Problems solved by technology

The method overcomes the disadvantages of the existing flue-cured tobacco floating seedling raising substrates, such as high production cost, poor permeability, and pollution to the environment
But this method has the following disadvantages: the dry porosity of mountain sand and river sand reaches 8.5-10.1%, and the fertilizer retention capacity is poor, thereby increasing the difficulty of fertilization, and it is labor-intensive and time-consuming; simply using sand as the matrix material does not contain organic matter and Nutrient elements, the seedlings cultivated have a low emergence rate and a low seedling rate

Abstract

The invention discloses a flue-cured tobacco floating seedling matrix, a preparation method and the application thereof. Specifically, the matrix is made by mixing and sterilizing 10-65 parts of shale and 0-20 parts of organic fertilizer calculated by weight ratio. The preparation method thereof mainly comprises the following steps: (1) treatment of materials: the shale is crushed and sieved to cause the particle size of the shale to be 0.56mm for use; (2) mixing and disinfecting: the treated shale or the mixture that the treated shale and an organic fertilizer are fully mixed is sterilized and disinfected to obtain the flue-cured tobacco floating seedling matrix. The flue-cured tobacco floating seedling matrix and the preparation method thereof can solve the problems that the sources of the flue-cured tobacco floating seedling matrix materials are difficult, the production cost is high, and resource utilization contradicts the ecological environment protection. The flue-cured tobacco floating seedling matrix of the invention has the advantages that necessary nutrient components are provided for the growth of the flue-cured tobacco seedling, and the rate of emergence and the planting percent of the seedlings are improved.

Description

technical field [0001] The invention relates to a flue-cured tobacco floating seedling raising substrate, in particular to a high-efficiency and low-cost flue-cured tobacco floating seedling raising substrate and a preparation method and application thereof. Background technique [0002] Floating seedling cultivation is the main seedling raising method adopted in flue-cured tobacco production in recent years. The seedling raising substrate material is mixed substrate, the formula is complicated, and the production cost is high. [0003] Chinese Patent No. 200510048691.3 provides a floating seedling raising method using sand as a matrix material. The method overcomes the defects of high production cost, poor permeability and pollution to the environment of the existing flue-cured tobacco floating seedling raising substrate. But this method has the following disadvantages: the dry porosity of mountain sand and river sand reaches 8.5-10.1%, and the fertilizer retention capacit...
