Problems solved by technology

[0005] These pollutants not only seriously damage the ecological balance of the environment, seriously inhibit the growth of agriculture and reduce the yield of crops, but also will be absorbed by the planted crops and enter the human body through the food chain, resulting in a large amount of pollutants deposited in the tissues and organs of the human body. pose a huge threat to human health

Abstract

The invention belongs to the technical field of fertilizers, and concretely discloses an environmentally-friendly fertilizer and a making method thereof. The making method of the environmentally-friendly fertilizer comprises the following steps: mixing an organic fertilizer, a charcoal fertilizer, a composite fertilizer, modified starch, a phosphate compound and a composite biological inoculant according to a certain mass fraction ratio, standing the obtained mixture, drying the mixture, granulating the dried mixture, and drying obtained granules, wherein the charcoal fertilizer is prepared from hickory shells, rice straws, rice husks, corn stalks and corncobs according to a certain weight ratio; and the composite bacterial inoculant is prepared by mixing ferment bacteria, Arthrobacter globiformils, Bacillus megaterium, Pseudomonas pseudoacaligenes, polysorbate and sodium dodecyl sulfate according to a certain weight ratio. The environmentally-friendly fertilizer prepared in the invention has the characteristics of comprehensive and balanced nutrition, high utilization rate, no pollution, effective increase of the output of crops, and effective absorption and degradation of heavy metals and organic pollutants from soil, so the absorption of pollutants by crops is reduced, thereby guaranteeing the health of human bodies.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of fertilizers, in particular to an environment-friendly fertilizer and a production method thereof. [0003] 【Background technique】 [0004] According to statistics, due to unreasonable use of chemical fertilizers, pesticides and organic fertilizers and low utilization rate of fertilizers, serious soil pollution has been caused. Among them, my country's heavy metals polluted more than 20 million hectares of farmland soil 2 , accounting for 16.4% of the total cultivated land area, plus 9.33 million hm of farmland soil contaminated by pesticides 2 2.17 million hm of farmland polluted by sewage irrigation 2 , 500,000 hm of oil-contaminated soil 2 100,000 hm of farmland polluted by industrial waste 2 and 200,000 hm of soil contaminated by mining 2 , a total of 32.3 million hm 2 , equivalent to 26.5% of the country's arable land at that time. The results of the first national survey on soil pollut...
