Biomass fertilizer prepared from excrement generated in aquatic product cultivation

Abstract

The invention relates to a biomass fertilizer prepared from excrement generated in aquatic product cultivation. The biomass fertilizer is prepared from excrement generated in aquatic product cultivation as a main raw material, and a potash fertilizer, fish powder and strain powder as auxiliary materials. The raw materials comprise 2 to 8 weight percent of the potash fertilizer, 2 to 4 weight percent of the fish powder, 0.5 to 2 weight percent of the strain powder and the balance being the excrement generated in the aquatic product cultivation. By effectively recovering nutritional ingredients in the excrement, which is generated in the aquatic product cultivation and taken as the main raw materials, the problems of environmental pollution and resource waste caused by the excrement generated in the aquatic product cultivation are solved; meanwhile, by taking the potash fertilizer, the fish powder and the strain powder as the auxiliary materials, the soil fertility can be remarkably improved through the fertilizer, the usage quantity of a chemical fertilizer is greatly decreased, and the chemical fertilizer is even not needed.

Description

technical field [0001] The invention relates to a fertilizer for improving soil, in particular to a biomass fertilizer. Background technique [0002] In terms of crop planting, my country has developed from farmyard manure to chemical fertilizers. Chemical fertilizers are used in agriculture. Although they can increase the production and income of agricultural products, chemical fertilizers pollute the environment. First of all, long-term application will easily cause soil compaction, damage the soil structure, gradually reduce many beneficial microorganisms in the soil, lead to a decrease in soil organic matter content, and imbalance of various nutrient ratios, making it difficult to meet the actual growth needs of crops. Secondly, crops are highly dependent on chemical fertilizers and pesticides, and the use of chemical fertilizers must be increased year by year. Otherwise, crops will grow slowly, and pests and diseases will be serious, resulting in reduced production; and...

Problems solved by technology

[0003] The object of the present invention is to address the above-mentioned deficiencies, and to provide a biomass fertilizer prepared from feces produced by aquatic product cultivation, which can effectively recycle and utilize the nutrients in the feces produced by aquatic product cultivation, and solve the problem of feces produced by aquatic product cultivation. The problem of polluting the environment can also be rationally used to improve the soil environment by using the nutrients in the feces produced by aquatic product farming
