Preparation method of organic substrate for raising rice seedlings

Abstract

The invention discloses a preparation method of an organic substrate for raising rice seedlings. The substrate consists of a fermented mixed material of vinegar residue, cassava residue and straw powder, coconut chaff wet materials, plant ash, grass carbon and vermiculite. The preparation method comprises the following steps: airing crop straws, and crushing the crop straws into particles of which the sizes are smaller than 5mm; composting, thoroughly decomposing and fermenting the mixed material by using fermentation strains containing beneficial microorganisms, wherein the vinegar residue accounts for 25-35 percent, the cassava residue accounts for 40-50 percent, and the straw powder accounts for 15-25 percent; adding the coconut chaff wet materials, the plant ash, the grass carbon, the vermiculite, a compound fertilizer, a synergist and chlormequat chloride; fully stirring and uniformly mixing the raw and auxiliary materials, and then performing bagging, weighing, packaging and warehousing. Organic wastes serve as raw materials, so that the nutrition is comprehensive; pest and disease damages and worm eggs are eliminated due to fermentation by virtue of the beneficial microorganisms, the application effect is particularly good, and the method is suitable for raising the rice seedlings, can promote the healthy growth of the seedlings and can be popularized and applied all over the country.

Description

technical field [0001] The invention relates to a method for preparing a rice seedling raising substrate, in particular to a method for manufacturing an organic substrate for rice seedling raising, and belongs to the technical field of food crop production. Background technique [0002] Rice is one of the food crops with the largest cultivated area in my country. Because rice cultivation requires seedling cultivation, for a long time, the traditional rice seedling fields have been picking fields with relatively good soil fertility before the seedling raising season, planting green manure, plowing with the surface soil, retting and leveling, and then raking the ditch to dry and organize. Seedbed, rice seeds are directly sown in the soil seedbed, and the surface is covered with nutrient soil made of mixed piles of topsoil, frozen soil, plant ash, organic fertilizer, etc. Taking soil year after year is likely to cause damage to the soil cultivation layer and loss of surface nut...

AI Technical Summary

Problems solved by technology

[0003] Since most agricultural and forestry waste residues such as crop straws are relatively long and light in texture, transportation, crushing and processing are difficult and expensive, coupled with low nutrient content, high fiber content, slow decomposition speed, and long maturity cycle; Agaricus bisporus And the leftovers of Flammulina velutipes have a long fermentation time, and the large-scale commercial application has certain limitations
