Special organic-inorganic composite biological pesticide-fertilizer for tea and preparation method thereof

Abstract

The invention provides a special organic-inorganic composite biological pesticide-fertilizer for tea. The special organic-inorganic composite biological pesticide-fertilizer for tea is characterized by comprising the following raw materials in parts by weight: 70-90 parts of urban domestic garbage, 10-15 parts of guano, 5-8 parts of bone meal, 4-6 parts of gelatin, 20-25 parts of tree ash, 20-25 parts of modified diatomite, 5-10 parts of monoammonium phosphate, 12-15 parts of urea, 12-15 parts of mineral slag, 5-10 parts of potassium chloride, 3-5 parts of paulownia sawdust, 10-12 parts of animal hair, 3-5 parts of sclerotium mylittae, 3-5 parts of betelnut, 3-5 parts of herba artemisiae scopariae, 5-8 parts of radix sophorae flavescentis, 3-5 parts of radix scutellariae, 10-15 parts of sodium fulvate, 3-5 parts of peat, 0.08-0.12 part of ammonium molybdate, 1.5-2.5 parts of ferrous sulfate, 0.7-1.0 part of copper sulfate, 0.8-1.2 parts of borax and 0.1-0.2 part of EM (effective microorganism) strain. The pesticide-fertilizer disclosed by the invention has the advantages of scientific ratio of nitrogen, phosphorus and potassium, easiness in absorption by crops, obvious yield-increasing benefit and the like. By applying the pesticide-fertilizer, the nutrient absorption of trees can be balanced, the tea quality can be effectively improved and the taste of the tea can become thick.

Description

technical field [0001] The invention relates to a medicinal fertilizer, in particular to an organic-inorganic compound biological medicinal fertilizer special for tea and a preparation method thereof. Background technique [0002] Agricultural production requires soil to provide nutrients for crop growth and a living environment. The application of chemical fertilizers has played a key role in increasing agricultural incomes for many years. However, due to the long-term application of chemical fertilizers, insufficient supply of organic fertilizers, and imbalances in the proportion of various nutrients, the ecological environment of farmland, soil physical and chemical properties, and soil biota have been damaged to varying degrees, and the quality of agricultural products has been affected to a certain extent. Therefore, chemical fertilizer pollution has become a major public hazard in the world today. The current status of soil resources in my country urgently need...

Problems solved by technology

[0005] my country is a large agricultural production country. With the high utilization of fertilizers, the requirements for fertilizers are constantly increasing. At present, a large amount of inorganic fertilizers are used, which seriously leads to the increase of harmful substances in crops, poor quality, and incomplete nutrition. Secondly, the soil is easy to Hardening, poor drought resistance, and poor water retention performance, which seriously affects the normal growth of crops and poor economic benefits
