High-efficiency multi-bacterial activity biogas residue biofertilizer and preparation method thereof

Abstract

The invention discloses a high-efficiency multi-bacterial activity biogas residue biofertilizer and a preparation method thereof, and relates to the field of farm fertilizers. The biofertilizer is prepared by mixing and granulating 44 to 54 weight parts of biogas residue, 10 to 15 weight parts of potassium chloride, 10 to 15 weight parts of humic acid, 0.4 to 0.6 part of secondary and micro-element, 0.4 to 0.6 weight part of microbe, 5 to 10 weight parts of urea, 10 to 15 weight parts of monoammonium phosphate and 5 to 10 weight parts of ammonium chloride. The high-efficiency multi-bacterial activity biogas residue biofertilizer has the characteristics of better multiple bacteria co-existing environment, stronger bioactivity, higher fertilizer efficiency, complete organic matters, effective micropopulations and chemical nutrients, controlled-release effect and the like, can be used as a fertilizer for rice, also can be used as a fertilizer for Upland food crops, vegetables, melons and fruits and fruit trees, and can improve the fertility of land and the utilization rate of the fertilizer, improve the quality of agricultural products, enhance plant diseases and insect pest resistance and drought resistance, purify and repair soil and the like after being applied.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a high-efficiency biogas residue multi-strain active biological fertilizer made from fermented biogas residue and a preparation method thereof. Background technique [0002] Due to the excessive use of chemical fertilizers and pesticides in my country's planting industry for many years, it has caused soil compaction, soil fertility decline, rampant pests and diseases, and agricultural environment pollution; due to the use of agricultural products contaminated by chemical fertilizers and pesticides as feed, the feed conversion rate is low, and the disease is serious. The feed ratio is only half of that of the United States and Canada. What is more serious is that the residues of chemical fertilizers and drugs affect people's health, affect the export of agricultural and livestock products, and seriously restrict the sustainable development of agriculture. In recent years, bi...

Problems solved by technology

At present, there are many types of biological fertilizers on the market, mainly including rhizobia fertilizers, nitrogen-fixing bacteria fertilizers, phosphorus- and potassium-dissolving bacteria fertilizers, antibiotic fertilizers and fungal fertilizers, etc. Some of these biological fertilizers contain a single effective bacterium Some products are compound products made by mixing nitrogen-fixing bacteria and phosphorus- and potassium-solubilizing bacteria. However, the multi-bacteria symbiosis environment in most biological fertilizers is poor, and the activity of biological bacteria is weak, resulting in low fertilizer efficiency.
