Disease-proof growth-accelerating soil additive and preparation method thereof

Abstract

The invention discloses a disease preventing and growth promoting soil additive and a manufacturing method thereof. Well-composted straws and dropping of livestock and poultry are dried and crushed and coal ash and calcium lime are crushed and screened; 1-50 portions of the well-composted straws, 1-50 portions of the well-composted dropping of livestock and poultry, 20-90 portions of the coal ashand 1-10 portions of calcium lime are prepared according to weight ratio and then evenly mixed to be made into a comprehensive soil additive required by the invention. The invention has low cost and the mixed finished product has rich organic substances and a plurality of mineral elements required by plant growth. By being applied on a lawn, the soil additive can improve soil granulation structure, increase soil fertility, promote the mass multiplication of useful microorganism at roots and effectively control the propagation of harmful microorganisms so as to ensure the strong growth of the lawn and enhance disease prevention and stress tolerance.

Description

technical field [0001] The invention relates to a soil additive and a production method thereof, in particular to a soil additive for disease prevention and growth promotion and a production method thereof. Background technique [0002] The lawn grows in fertile soil, with sufficient water and fertilizer, often has very low mowing, the lawn grass density is high, the humidity is high, the dew retention time is long, the plant growth is weak, and the lawn itself has poor stress resistance, especially resistance to diseases. So that the whole ecosystem is conducive to the breeding of pathogenic microorganisms, and finally the generation of diseases and other injuries. At the same time, the lawn is a perennial plant, and soil plowing cannot be carried out, which provides good conditions for the accumulation of soil-borne and root disease pathogens; the lawn is in the form of a carpet, and the roots are connected, which provides favorable conditions for the expansion of lawn roo...

Directly cause some diseases without specific control agents

2. Biological fungicides are an ideal class of fungicides that are safe for the environment and humans. However, biocides are mainly composed of antagonistic organisms, and usually lack the consistency and reliability required for the application of chemical fungicides. Using biological agents to prevent diseases It is still relatively small, and only in 1999, Trichobacterium extremophilus was registered in the UK for the prevention and treatment of some turf diseases on the lawn.

3. Commonly used methods to prevent and control soil-borne and root diseases are the use of crop rotation and plowing methods, which are difficult to implement in lawn management
