Abstract

The invention discloses a rice seedling substrate, a rice seedling substrate board and a preparation method of the rice seedling substrate. The rice seedling substrate can meet all nutrient elements required by rice seedlings, is simple and convenient in seedling operation, and meanwhile, solves the problem of difficulty in taking soil and the problem of seedbed weeds. A microorganism bacterium agent in the rice seedling substrate can kill pathogenic bacteria, change the rhizospheric microorganism environment and improve disease resistance of rice. The rice seedling substrate contains a compound slow release fertilizer and can meet the requirement of seedlings for nutriment in 40 days. Meanwhile, the rice seedling substrate is added with an efficient, low-toxic and low-residual green pesticide, does not propagate disease pests and weeds, is green, environmental-friendly, healthy and safe, and can increase soil organic matter and enhance land productivity when being used for long time. Moreover, according to the rice seedling substrate board, a seedling seedbed is good in air permeability; seedling roots grow vigorously; seminal roots and secondary roots are long in service life; roots are long; the number of the roots is great; a entangle root effect is obviously better than that of soil seedling; cultured rice seedlings are high in disease resistance and can effectively prevent and treat bacterial wilt and damping off in the rice seedling stage.

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...
