Abstract

The invention discloses a rice seedling substrate, a rice seedling substrate plate and a preparation method of the rice seedling substrate plate. The rice seedling substrate can meet all nutritional elements needed for rice seedling, seedling operation is simple and convenient, and at the same time, the problems of difficulty in soil obtaining and seedbed weed are solved. Microbial agents in the rice seedling substrate can kill pathogens, change the rhizosphere microbial environment and improve the disease resistance of rice. The rice seedling substrate contains multiple controlled release fertilizer which can meet nutritional needs of seedlings for 40 days. Meanwhile, the rice seedling substrate is added with high-efficiency low-toxicity low-residual green pesticides, does not spread pests and weeds, is green, environmentally friendly, healthy and safe, and can increase soil organic matter and fertility after long-term use. In addition, a seedbed of the rice seedling substrate plate had good air permeability, roots of seedlings grow strongly, the life of seed roots and secondary roots is long, roots are long and more, a root twisting effect is better than that of soil seedling, cultured rice seedlings are strong in disease resistance, and bacterial wilt and damping off of rice in a seedling stage can be effectively controlled.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a rice seedling raising substrate and a rice seedling raising substrate board. Background technique [0002] At present, my country's rice planting mostly adopts traditional field soil or nutrient soil to raise seedlings in seedling trays. This kind of seedling tray needs to dig a lot of upland soil, and add fertilizers, pesticides and acid adjustment treatment to configure it into nutrient soil, and then it can be used on the seedling bed of the seedling tray, which adds a lot of tedious work for rice farmers. The soil also needs to be topdressed with fertilizers in the middle and late stages of seedling cultivation, otherwise it will be difficult to cultivate strong seedlings. Moreover, it will also be infected by diseases and insect pests, the root system of rice seedlings is not developed enough, excessive growth, slow seedlings after transplanting and other shortco...
