Process for producing environmentally-friendly full-degradable liquid mulch film capable of turning into fertilizer by using coal humic acid

Abstract

The invention provides a method for producing an environmentally-friendly full-degradable liquid mulch film capable of turning into a fertilizer by using coal humic acid. The process comprises the following steps: finely selecting weathered coal, brown coal, peat or rogued turf, removing impurities, and then adding the coal into a crusher and crushing the coal into coal powder with the grain size of 100-150 meshes; adding raw materials into a reaction kettle in a raw material weight ratio of coal powder to potassium hydroxide to potassium carbonate to water equal to (100-120):(0.2-0.7):(0.2-0.6):(200-320), stirring, heating the mixture, standing for settling, and then taking liquid supernatant, thereby acquiring a potassium humate solution; and enabling raw materials to react in a raw material weight ratio of potassium humate solution to boric acid to potassium silicate to cellulose to cross-linking agent to water to propylene glycol monomethyl etheracetate to ammonium nitrate equal to (10-12):(1.8-2.5):(1.2-1.7):(0.15-0.17):(0.25-0.27):(20-30):(0.2-0.3):(0.1-0.2), thereby generating the environmentally-friendly full-degradable liquid mulch film capable of turning into the fertilizer. The process provided by the invention is used for producing the environmentally-friendly full-degradable liquid mulch film by using coal humic acid. After being used, the liquid mulch film is free from being cleared away and is turned into the fertilizer which is absorbed by crops, thereby solving the 'plastic pollution' problem of plastic mulch films.

Description

technical field [0001] The invention belongs to a technique for producing an environment-friendly fully degradable fertilization liquid mulch film by using coal humic acid. Background technique [0002] The plastic mulch that has been widely used can absorb heat and increase temperature, preserve moisture, preserve seedlings, and increase crop yield. However, the plastic mulch after use cannot be degraded. If it is not removed, it will remain in the soil for a long time, preventing the growth of crop roots and reducing crop yield. . The problem of "white pollution" caused by plastic mulch needs to be solved urgently. Relying on manual removal is time-consuming and laborious, and the removal effect is not ideal. Coal humic acid is a natural organic polymer compound, a multifunctional chemical material with a wide range of industrial and agricultural uses, and is widely used in forestry, animal husbandry and medicine. Humic acid is rich in almost all amino acids, various enz...
