A kind of rice seedling raising substrate and its industrialized production method

Abstract

The invention discloses a rice seedling raising matrix and an industrial production method thereof. The matrix comprises the following components: an organic fermentation material, vermiculite and a matrix conditioning agent, wherein the mass ratio of the organic fermentation material to vermiculite is (6-10): (1-3); the addition amount of the matrix conditioning agent is 3-9% of the total mass of the matrix; the organic fermentation material is formed by mixing and fermenting tea dregs, Chinese medicine residues and perlite according to the dry matter mass ratio of (40-51): (23-30): (7-9); the matrix is rich in active organic matters and various nutrients, and can replace the traditional nutrient soil matrix to realize protection for arable soil, consumption of organic wastes, preservation of ecological environment, labor-saving and cost-saving seedling raising, and low-carbon cycle. Through adoption of the matrix, seedling plates can be used for raising seedlings, the seedlings are strong and in order, the root system is strong, and the seedlings raised using the seedling plates are strong in deep and twisted rooting capability; compared with the conventional seedling raising production using nutrient soil, the seedling raising using the matrix is reduced in integrated cost, such as labor cost, by 700-800 Yuan per mu.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a rice seedling raising substrate and an industrialized production method thereof. Background technique [0002] With the development of agricultural mechanization, the adjustment of rural industrial structure and the transfer of rural labor force, the area of ​​machine-transplanted rice has increased significantly. For example, the proportion of machine-transplanted rice in Nanjing, Jiangsu Province has reached 69%. [0003] Machine-transplanted seedlings must be raised in seedling trays. At present, nutrient soil seedling trays are still used in rural areas, which consume a large amount of plow layer soil every year (at least 120,000 cubic meters of plow layer soil is consumed for seedling cultivation of 1 million mu of field rice), and manual soil screening costs Labor and effort; at the same time, the compounding of nutrient soil needs to add livestock and poultry manur...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is: at present, rice seedling raising basically still uses nutrient soil for seedling tray raising, which consumes a large amount of arable soil of good fields every year, and is labor-intensive, long production cycle, and lacks professional research and cultivation. The quality of seedlings is unstable. In order to protect the cultivated soil of good fields, alleviate the labor shortage of agricultural production enterprises, meet the needs of large-scale planters for large-scale seedling trays, expand the source of seedling substrate raw materials, and reduce the cost of substrates, research on physical and chemical materials suitable for seedling trays. The nutrient-type rice seedling-raising substrate with excellent properties is imminent
