Problems solved by technology

[0002] my country is a country with a long history of rice planting. The traditional seedling cultivation uses fertile plow layer soil as the seedling bed soil. Planting one mu of rice requires 150 kg of seedling bed soil per year. The selection of plow layer soil also causes damage to farmland soil resources.
At present, many studies on the use of substrates to replace nutrient soil for rice seedling raising have also been carried out in China. The rice seedling raising substrates are basically peat, silica, perlite mixed with nitrogen, phosphorus, potassium, trace elements, fungicides, and insecticides. The peat is a non-renewable resource, and it needs additional nutrients to supplement, which will affect the environmental protection. Therefore, the rice seedling raising substrate should gradually become environmentally friendly, economical, technical and food-safe on the basis of soilless cultivation. change in direction

Abstract

The invention discloses an organic substrate for raising rice seedlings. The substrate is prepared from powders of livestock and poultry manure subjected to harmless treatment, waste powders after plant straw and fruit processing, humic acid, metalaxyl, fludioxonil, azoxystrobin, trace elements, complexing agents, enhancers, drought-resistant agents, nitrogenous fertilizers, phosphate fertilizers,potash fertilizers, long-acting organic PH regulating agents, fillers and additives. The organic substrate, by adopting the leftovers after crop straw and fruit processing, the powders of livestock and poultry manure subjected to harmless treatment and microbial strains as the main raw materials, does not need peat and plough layer soil, thereby reducing the utilization of non-renewable resourcesand the damage to farmland soil. The organic substrate for raising the rice seedlings has good packing, reduces the incidence of blight, bakanae disease and cotton rot, promotes fast green return, more tillering and early maturation of rice, and can increase the yield and the rice output rate.
