Rice seedling raising organic matrix

Abstract

The invention discloses a rice seedling raising organic matrix, and belongs to the technical field of rice seedling raising. The matrix comprises a vinegar residue, cassava residue and straw powder fermentation-treated mixture, a coconut chaff wet material, plant ash, peat and vermiculite. The matrix comprises 3-6 parts of the vinegar residue, cassava residue and straw powder mixed organic fermentation material, 1-2 parts of the coconut chaff wet material, 1-2 parts of the plant ash, 1-2 parts of the peat and 0.5-1 part of the vermiculite, and according to the material volume, a compound fertilizer and a synergistic agent and a stocky agent are added. The matrix comprises 2-4% of total nutrient, 40-50% of water, the total porosity is 65-75%, the volume weight is 0.35-0.5 g / ml, the particle diameter is less than or equal to 5mm, organic matter content in the dry matrix is more than or equal to 30%, the EC Value is 1.0-2.0 mS / cm, the gas water ratio is 1:2-4, and pH is 5.5-7.0. The matrix is a granular solid which is brown or black brown in appearance, and free of peculiar smell. The rice seedling raising organic matrix is prepared from vinegar residue, cassava residue, straw, coconut chaff and other organic waste as raw materials, is comprehensive in nutrient, stable in quality, and suitable for rice seedling raising, and can promote the robust growth of the seedlings.

Description

technical field [0001] The invention relates to a rice seedling raising substrate, in particular to an organic rice seedling raising substrate, belonging 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 nutrients. Chinese patent CN101507410B discloses the "mach...

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
