Biological organic fertilizer

Abstract

The invention relates to a biological organic fertilizer which is prepared from the following raw materials in parts by weight: 0.5 part of Bacillus amyloliquefaciens, 0.5 part of Bacillus mucilaginosus, 35-50 parts of fermented chicken manure, 15-25 parts of fermented cattle manure, 15-20 parts of fermented mushroom residue and 19 parts of medical stone. Every part of medical stone contains 66.88% of silicon oxide, 17.17% of aluminum oxide, 4.24% of potassium oxide, 1.59% of sodium oxide, 1% of magnesium oxide, 1.17% of calcium oxide, 2.66% of iron oxide, 0.37% of titanium oxide and 0.09% of manganese oxide. The effective viable count of the Bacillus amyloliquefaciens and Bacillus mucilaginosus is at least 20 million/g, and the content of the organic matters, including the fermented chicken manure, cattle manure and mushroom residue, is greater than 40.0% of the total nutrients. The effective viable bacteria contained in the biological organic fertilizer can solve the problem of various diseases caused by fungi, bacteria and viruses in the soil, can implement phosphate solubilization, potassium solubilization and nitrogen fixation, and reduce the application amount of large chemical fertilizers. The biological organic fertilizer contains abundant organic matters, and thus, is capable of improving the soil, activating the soil, eliminating soil hardening and enhancing the water storage and fertilizer retention capacities of the soil.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a bio-organic fertilizer. Background technique [0002] In terms of crop cultivation in China, chemical fertilizers have been used for more than 50 years. Although chemical fertilizers have played a significant role in increasing production and income, long-term application will damage the soil, resulting in a decrease in soil organic matter content and a serious proportion of various nutrients. Imbalance, the soil begins to acidify and compact, the physical and chemical properties of the soil and soil microbial flora are severely damaged, resulting in a decline in its water storage and fertilizer retention capacity, poor air permeability, and it is difficult to meet the growth needs of crops; crops are more dependent on chemical fertilizers and pesticides. Otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced yield or even no...

[0002] In terms of crop cultivation in China, chemical fertilizers have been used for more than 50 years. Although chemical fertilizers have played a significant role in increasing production and income, long-term application will damage the soil, resulting in a decrease in soil organic matter content and a serious proportion of various nutrients. Imbalance, the soil begins to acidify and compact, the physical and chemical properties of the soil and soil microbial flora are severely damaged, resulting in a decline in its water storage and fertilizer retention capacity, poor air permeability, and it is difficult to meet the growth needs of crops; crops are more dependent on chemical fertilizers and pesticides. Otherwise, the crops will grow slowly, and the pests and diseases will be serious, resulting in reduced yield or even no harvest; after the chemical fertilizers are applied to the farmland, the actual utilization rate is only 30% on average, and most of them will flow into rivers and lakes with farmland drainage or remain in the soil and plants And crops, not only bring environmental pollution but also endanger human health and life safety, deterioration of the agricultural ecological environment; In addition, in recent years, the effect of increasing production of chemical fertilizers has also decreased significantly, and the growth rate of chemical fertilizer use far exceeds the growth rate of crop production; Finally, the large-scale use of large amounts of elements makes the loss of trace elements in the soil more and more serious, and affects the absorption and utilization of trace elements in the soil, causing various physiological diseases; these have become obstacles to the sustainable development of agriculture and need to be resolved urgently
