Bioactive organic pesticide-added fertilizer as well as preparation method and application of bioactive organic pesticide-added fertilizer

Abstract

The invention provides a bioactive organic pesticide-added fertilizer. The bioactive organic pesticide-added fertilizer contains 12-15% of total nutrients, wherein the mass ratio of N to P2O5 to K2O is (3-6) to (0-2) to (5-7); the living bacteria count in the bioactive organic pesticide-added fertilizer is 50 million / g to 100 million / g; besides, the bioactive organic pesticide-added fertilizer contains 60%-75% of organic matters, less than or equal to 30% of moisture and 0.2-0.3% of nicotine, has the fineness of 20-40 meshes and the pH of 6.0-7.0. The preparation method of the bioactive organic pesticide-added fertilizer comprises the following steps: adding tobacco stems, cake meal and a microbial fermentation agent into a material mixer, adding water while mixing, and composting the materials for fermentation to obtain the fermented and decomposed materials; next, adding the fermented and decomposed materials and a functional microbial agent into the mixer, mixing evenly and crushing, screening to obtain powder and packaging to obtain a finished product. The bioactive organic pesticide-added fertilizer does not contain inorganic nutrients or chemical additives, and contains a plurality of soil active microorganisms, and is capable of effectively solving the problems of soil hardening and the like, capable of improving the soil structure and controlling diseases and pests, and enhancing the utilization of the nutrients caused by the crops.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a bioactive organic medicinal fertilizer and its preparation method and application. Background technique [0002] With the continuous development of economy and society, the problem of soil degradation has become increasingly prominent, mainly manifested as soil compaction and hardening, erosion, salinization, acidification, element imbalance, chemical pollution, loss of organic matter and degradation of flora and fauna, etc., serious The development of land productivity is restricted. According to a report released by the Food and Agriculture Organization of the United Nations (Food and Agriculture Organization) in November 2011, a quarter of the world's existing arable land is "seriously degraded", threatening the goal of increasing global food production by 70% by 2050. The report, "The State of the World's Cultivated Land and Water Resources," shows that 25 percent of the world's...

Problems solved by technology

However, the disadvantage of organic fertilizer is that the nutrient content is low and the amount used is large. If the fermentation is not complete, it may cause pollution to the environment.

It is made by fermenting organic materials with strains and packaging them into organic fertilizers. The strains are relatively single, and no functional microbial agents are added in the later stage. At the same time, it does not have the effect of preventing pests and diseases.
