Biological organic fertilizer

Abstract

The invention relates to the field of fertilizers, and in particular to a biological organic fertilizer, which consists of the following components in parts by weight: 20 to 25 parts of straw, 10 to 20 parts of sawdust, 10 to 12 parts of expanded perlite powder, 1 to 2 parts of nitrification inhibitor DMPP (3,4-dimethylpyrazole phosphate), 0.3 to 0.5 parts of tea saponin, 0.1 to 0.9 parts of bacillus amyloliquefaciens, 0.1 to 0.9 parts of bacillus mucilaginosus, 35 to 50 parts of fermented chicken feces, 15 to 25 parts of fermented cow dung, 15 to 20 parts of fermented mushroom bran and 18 to 20 parts of medical stone. When the fertilizer disclosed by the invention is used, the nutrition of crops can be complete, absorption is good, the fertilizer can quickly take effect, the fertilizer can be slowly released, the fertilizer effect is long, growth is vigorous, and moreover, the problems of severely low organic matter content in field soil and soil hardening can be solved. Since the biological organic fertilizer contains bacillus amyloliquefaciens and bacillus mucilaginosus, the biological organic fertilizer not only can treat various diseases caused by fungi, bacteria and viruses in soil, but also can dissolve phosphorus and potassium, fix nitrogen and reduce the amount of applied fertilizer, and furthermore, since the biological organic fertilizer contains a great deal of organic matter, the biological organic fertilizer can improve and activate soil, eliminate soil hardening and enhance the water and fertilizer retention capability of soil.

Description

technical field [0001] The invention relates to the 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 harvest; ...

[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
