Ecological multiple-effect spray fertilizer application with liquid mulch film function and method of preparing the same

Abstract

The present invention discloses an ecological multi-effect spraying fertilizer with the function of liquid film, and a production method thereof. The fertilizer is a viscous pasty material that is made by mixed materials that are biodegraded by micro organism bacterial liquid. The bacterial liquid consists of composite microbial agents, which can be used for decomposing lignocellulose, and microbiological nutrient solution. The mixed materials consist of straw powder, fertilizer, coal powder and membrane-forming material that consists of porous layered silicate powder, kaolin and improved starch. In the production method, the mixed materials are added into the bacterial liquid of the micro organisms for the reaction of biodegradation under the conditions of pH of 3.2 to 8.3 and the temperature of 0 to 75 DEG C; after 6 to 25 days, the viscous pasty product can be prepared. The spraying fertilizer can be sprayed in the field to form a liquid film that integrates the functions of fertilization and preservation of soil moisture. And the spraying fertilizer has the advantages of the solidification of water and fertilizer, environmental protection, no potential for secondary pollution, improved aggregate structure of the soil and a large amount of straw that is recycled in the field.

Description

technical field [0001] The invention relates to a fertilizer for plant growth, in particular to an ecological multi-effect spray fertilizer with the effect of a liquid film and a production method. Background technique [0002] In the past 100 years, the land environment has experienced the following problems: [0003] 1. 34% of the world's land area is desertified, 27.4% of China's land area is desertified, and 7.9% is salinized; [0004] 2. More than 60% of China's soil erosion area; soil moisture is destroyed, heavy metals, dioxins, and organic pesticide residues exceed the standard (more than 2.4 times the European and American standards) of cultivated land accounted for 76.4%; [0005] 3. The water body is polluted at a rate of 92%; more importantly, 10% of this pollution comes from industrial pollution, and 90% comes from soil erosion, extensive use of chemical fertilizers, and a large number of large-scale pollution caused by the decline in soil moisture conservation...

Problems solved by technology

[0005] 3. The water body is polluted at a rate of 92%; more importantly, 10% of this pollution comes from industrial pollution, and 90% comes from soil erosion, extensive use of chemical fertilizers, and a large number of large-scale pollution caused by the decline in soil moisture conservation capacity. Pollution, point pollution is easy to control, but surface pollution is large and wide and difficult to control;

[0006] 4. What is more serious is that the land use methods that cause this kind of land and the ecological environment security problems associated with the land, as well as the traditional fertilizers and farming methods that are used in large quantities, are still exacerbating this phenomenon;

[0007] 5. The current use of land is predatory:

[0010] c. The energy of the land is seriously unbalanced. Traditional agriculture focuses on "seed-type" harvesting. However, a large number of plant stems, leaves, roots and other substances obtained from the land are not fully utilized. The way of burning; "wasting energy and polluting the environment", this phenomenon is common in rural areas, what's more, when a large amount of precious straw is burned, the plane cannot take off and land normally;

[0011] d. What is even more worrisome is that organic waste has become a major public hazard to society. It pollutes the environment, devours cultivated land, and endangers people's health

As far as the large amount of polymer mulch currently used in the land is concerned, it has caused "white and terrible pollution" to the land; it is hard to imagine that in 20 or 30 years, when the land is full of non-degradable and refractory polymers In the case of materials, some pulverized polymer particles and particles may cause safety problems in the biological chain after entering the water body;
