Disease-resistant organic fertilizer used in organic agricultural industrial parks and preparation method thereof

Abstract

The invention discloses a disease-resistant organic fertilizer used in organic agricultural industrial parks and a preparation method thereof. The organic fertilizer is prepared by adding an organic fertilizer fermentation liquor, a liquid actinomycete agent, ascorbic acid, a synergistic microelement fertilizer, a soil water retaining agent, and the like by taking livestock and poultry manures, ground crop straws and rape seed cake as the main raw materials. Compounded with the ascorbic acid, the organic fertilizer can achieve the effects of boosting the immunities of crops, improving the disease and insect pest resistance capacities of the crops, especially reducing the disease and pest risks caused by continuous cropping of the crops and effectively resisting the common diseases of the crops, such as blights, greensickness, rhizoctonia solani, root rot, damping-off, anthracnose, sooty mold, gummy stem blights, gray mold and black roots, so that the usage amount of chemical pesticides is reduced, and the effect of simultaneous application of pesticides and fertilizers is achieved.

Description

technical field [0001] The invention relates to an organic fertilizer and a preparation method thereof, in particular to a disease-resistant organic fertilizer for an organic agricultural industrial park and a preparation method thereof. Background technique [0002] In recent years, with the continuous exposure of food safety incidents, organic agriculture, which was quite marginalized, has become a hot spot. Organic agriculture refers to the planting industry that uses organic fertilizers to meet the nutritional needs of crops or the breeding industry that uses organic feed to meet the nutritional needs of livestock and poultry without completely or basically using artificially synthesized fertilizers, pesticides, growth regulators, and livestock and poultry feed additives in production . At present, there are many organic fertilizer products on the market, and the main problems are as follows: (1) The products do not have disease resistance, and are prone to diseases dur...

Problems solved by technology

At present, there are many organic fertilizer products on the market, and the main problems are as follows: (1) The products do not have disease resistance, and are prone to diseases during the growth of crops, requiring the application of a large amount of pesticides, which cannot meet the production requirements of organic agricultural products; (2) ), the content of heavy metals and other pollutants in the product is high, long-term application will easily cause heavy metals to accumulate in the soil, resulting in excessive heavy metal content in agricultural products, shortening the service life of the land in the industrial park; (3), the product provides incomplete growth nutrients required by crops , seriously affecting crop yield and quality
