Organic-inorganic composite biological fertilizer pesticide special for soybean and preparation method thereof

Abstract

The invention provides an organic-inorganic composite biological fertilizer pesticide special for soybean. The organic-inorganic composite biological fertilizer pesticide is prepared from the following materials in parts by weigh: 40-50 parts of household garbage, 30-40 parts of mushroom slag, 20-25 parts of vinasse, 15-20 parts of humic acid, 10-13 parts of monocalcium phosphate, 12-14 parts of urea, 10-12 parts of potassium nitrate, 10-12 parts of quail feather, 20-24 parts of modified sepiolite, 3-4 parts of quispualis indica, 3-4 parts of stone-like omphalia, 4-6 parts of broom cypress fruit, 4-6 parts of rhizome nardostachyos, 4-6 parts of radix euphorbiae lantu, 0.1-0.2 part of boric acid, 0.05-0.1 part of sodium molybdate, 1-1.5 parts of zinc sulfate, 0.7-1.0 part of manganese sulfate, 5-7 parts of magnesium sulfate, 1-2 parts of nitrogen-fixing bacteria preparation and 3-5 parts of wintergreen oil. According to the invention, multiple organic wastes are mixed and then fermented so as to be changed into green organic fertilizer, environmental pollution is reduced, fermenting organic matter are mixed with inorganic fertilizer, and Chinese herbal medicine juice with insecticide function is added, therefore, the nutrition is more complete, and the sterilizing effect is increased. By applying the fertilizer, the quality of the soybean can be effectively improved, the soybean has green leaves and more flowers, the flowering period is prolonged, and the yield is improved.

Description

technical field [0001] The invention relates to medicinal fertilizers, in particular to a special organic-inorganic composite biological medicinal fertilizer for soybeans 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 needs...

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
