Organic fertilizer containing furfural residues and trace elements and preparation method thereof

Abstract

The invention discloses an organic fertilizer containing furfural residues and trace elements and a preparation method thereof. The organic fertilizer comprises the following components in parts by weight: 15 parts of furfural residues, 13 parts of chicken manure, 5 parts of amino acid, 15 parts of humic acid, 12 parts of bone meal, 20 parts of lignin, 15 parts of bentonite, 4.5 parts of biological bacterium and 0.5 part of trace element fertilizer, wherein the furfural residues are furfural waste residues generated in the furfural production process; and the biological bacterium is any one of or the mixture of more than any two of bacillus megaterium, rhizobium japonicum, rhizobium astragali and EM (effective microorganisms). The organic fertilizer and the preparation method have the advantages that the contents of CO3<2-> and HCO3<-> in soil can be reduced by adding lots of furfural residues to the active components, thus effectively improving the physical and chemical properties of soil and reducing the alkalinity of soil; and as the content of the furfural residues in the organic fertilizer is higher, Cl<-> can be reduced and the contents of such elements as organic matters, potassium and nitrogen in salinity soil can be increased by applying the organic fertilizer so that the elements promote growth of crops together with other nutrients in the organic fertilizer.

Description

technical field [0001] The invention relates to an organic fertilizer in the chemical field, in particular to an organic fertilizer containing furfural slag and trace elements and a preparation method thereof. Background technique [0002] my country is a country with a wide distribution of saline soil. According to rough calculations when compiling the distribution map of saline soil in my country, the area of ​​saline soil in China is about 1.0x108 hectares, of which modern saline soil accounts for about 37%, and residual saline soil accounts for about 45%. Potential saline soil accounts for about 18%. my country's saline soil is distributed in 19 provinces including Liao, Ji, Hei, Hebei, Shandong, Henan, Jin, Xin, Shan, Gan, Ning, Qing, Jiangsu, Zhejiang, Anhui, Fujian, Guangdong, Inner Mongolia and Tibet. According to the natural geographical conditions and soil formation process, it is divided into coastal humid-semi-humid sea-soaked saline area, northeast semi-humid-s...
