Problems solved by technology

Obstacles such as poor water and fertilizer retention in the seedling-raising substrate, poor packing, substrate floating during transplanting, thin seedlings, etc.
In addition, when using traditional nutrient soil to grow seedlings, it is very difficult to sterilize the bed soil and clean up the weeds in the seedbed. A little carelessness will cause the seedlings to get sick or be harmed by herbicides

Abstract

The invention provides a municipal sewage sludge rice seedling-raising substrate and a preparation method and application thereof. The rice seedling-raising substrate contains sludge, bean pulp hydrolysis residues and wood vinegar and further comprises other fertilizers and chemical regulators such as ammonium sulfate, zinc sulfate, multi-effect triazole and choline chloride. The sludge is a black and tasteless particle product rich in various nutrient components formed by performing aerobiotic high-temperature biological drying technology treatment on domestic sewage. The municipal sewage sludge rice seedling-raising substrate has the advantages of being abundant in microcellular structure, high in plasticity, high in binding force and the like, the water and fertilizer retention and temperature increasing effects are remarkable, and the agricultural standard is completely met. Harmless, stable, reduction and resource recycling of sludge is achieved, time and labor are saved, consumption of chemical fertilizer and pesticide is greatly reduced, the purpose of seedling strengthening is achieved, the production bottleneck that seedling culture and soil sampling are hard is completely solved, and the application prospect is wide.

Description

technical field [0001] The invention relates to a rice seedling-raising matrix formula and a preparation method thereof using sludge treated with domestic sewage as a matrix. Background technique [0002] The quality of rice seedling raising is one of the primary conditions for whether rice can win high yield. At present, the concentrated dry seedling raising technology is mostly used in northern my country. Every year, a large amount of topsoil of high-quality upland cultivated land needs to be collected as seedling bed soil. Difficulty in obtaining soil has become the main obstacle factor restricting rice production. In addition, successive years of soil borrowing and stacking of ridges have caused serious damage to the soil of the plow layer, which is likely to cause serious ecological problems such as soil desertification and soil erosion. At the same time, it also brings a series of problems such as more labor for seedling raising and transporting seedlings, complicate...
