Biological organic/inorganic compound fertilizer as well as preparation method and application of fertilizer

Abstract

The invention provides a biological organic / inorganic compound fertilizer. The biological organic / inorganic compound fertilizer contains 30-35% of total nutrients; the nutrient ratio of N to P2O5to K2O is (6-15) to (5-18) to (6-25); the living bacteria count in the bioactive organic insecticide-fertilizer is 50 million / g to 100 million / g; besides, the biological organic / inorganic compound fertilizer contains 15%-25% of organic matters, 0.15-0.20% of nicotine, less than or equal to 3.0% of chloride ions and less than or equal to 12% of moisture, has the fineness of 40-60 meshes and the pH of 6.0-7.0. The preparation method of the biological organic / inorganic compound fertilizer comprises the following steps: adding tobacco stems, cake meal, pig manure, artificial humic acid and a microbial fermentation agent to a 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, urea, ammonium dihydrogen phosphate, potassium chloride, active carbon nanopowder and a functional microbial agent to the mixer, mixing evenly and crushing, screening to obtain powder and packaging to obtain the biological organic / inorganic compound fertilizer which is high in content of nitrogen, phosphorus and potassium inorganic nutrients and organic matters, and has environment-friendly and insect-resistant effects.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a bio-organic-inorganic compound 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. Soil degradation caused by agricultural production activities is an important cause of land degradation. Extensive use of inorganic fertilizers leads to soil compaction, unreasonable irrigation causes soil salinization, and unreasonable use of pesticides leads to serious soil damage. These are the main reasons for the decline of soil fertility. [0003] In order to solve the problems existing in th...

AI Technical Summary

Problems solved by technology

Although this kind of basal fertilizer has the characteristics of combining organic and inorganic, it can not only meet the needs of crops for nutrients in the current season, but also prevent soil compaction and improve soil quality; but this fertilizer does not add microbial agents that can activate crop rhizosphere soil, and Nicotine against soil-borne diseases

Can not achieve the dual-purpose effect of fertilizer and medicine
