Organic inorganic composite biologic medical fertilizer special for rice and preparation method of fertilizer

Abstract

The invention discloses an organic inorganic composite biologic medical fertilizer special for rice. The fertilizer consists of the following raw materials in parts by weight: 15-25 parts of chicken manure, 8-14 parts of pig manure, 8-14 parts of sheep manure, 10-15 parts of rice chaff, 8-14 parts of straws, 6-12 parts of peat soil, 5-10 parts of animal born powder, 3-5 parts of animal fur powder, 5-7 parts of tree leaves, 4-6 parts of mushroom dregs, 13-16 parts of urea, 10-12 parts of superphosphate, 12-14 parts of calcium nitrate, 8-10 parts of potassium sulphate, 0.08-0.12 part of ammonium molybdate, 1.9-2.4 parts of copper sulfate, 0.8-1.2 parts of manganese sulfate, 3-5 parts of ferrous sulfate, 10-13 parts of potassium humate, 3-5 parts of eggshell powder, 0.4-0.6 part of glucose, 0.03-0.06 part of borax, 10-12 parts of animal fur and 3-4 parts of microorganism ferments. The fertilizer has the advantages that the fertilization and the sterilization are integrated, the cost is low, and has the environment-friendly and non-pollution effects.

Description

technical field [0001] The invention relates to an agricultural biological fertilizer, in particular to a special organic-inorganic composite biological fertilizer for rice and a preparation method thereof. Background technique [0002] 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 to supplement soil organic matter through artificial measures to ensure the level of agricultural pla...

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
