Organic liquid mulch film and production method thereof

Abstract

The invention relates to an organic liquid mulch film and a production method thereof. The organic liquid mulch film is produced through mixing 6 g of animal dander, 5 g of crop straw lignin, 0.11 g of a microelement fertilizer, 0.03 g of a pesticide, 0.09 g of a water retaining agent and 0.14 g of a curing agent according to a certain ratio. The production method comprises the following steps: washing the animal dander, boiling the animal dander to form liquid gel, airing the liquid gel to form solid gel, grinding the solid gel to form powder, screening the crop straw lignin, grinding the screened crop straw lignin to form powder, sequentially adding the microelement fertilizer, the pesticide, the water retaining agent and the curing agent in proportion, uniformly stirring for 9 min, preserving the above obtained stirring mixture in a refrigerator, taking the stirring mixture, mixing the stirring mixture with normal-temperature tap water with the weight 10.6 times the weight of the stirring mixture, uniformly stirring, and adding the obtained mixture solution into a sprayer to apply the solution in order to form the organic liquid mulch film.

Description

technical field [0001] The invention relates to the fields of forestry, agricultural fertilizers and plastic films, in particular to a liquid plastic film with organic fertilizers and a preparation method. Background technique [0002] At present, in the known cultivation of crops and flowers, the mulch used is plastic mulch and inorganic chemical liquid mulch. Although plastic mulch has the advantages of increasing ground temperature, suppressing weeds, and reducing soil moisture evaporation, the disadvantage is that the mulch is During laying, the labor intensity of farmers is high, and the work efficiency is low, and the manufacturing cost is also high. It takes at least two people per mu to spend two to three days to complete the laying, including the mulching after laying, followed by this kind of Plastic mulch cannot be degraded, and if it is left in the field, it will cause soil pollution. After a few years, it will reduce the yield of crops and even affect the qualit...

[0002] At present, in the known cultivation of crops and flowers, the mulch used is plastic mulch and inorganic chemical liquid mulch. Although plastic mulch has the advantages of increasing ground temperature, suppressing weeds, and reducing soil moisture evaporation, the disadvantage is that the mulch is During laying, the labor intensity of farmers is high, and the work efficiency is low, and the manufacturing cost is also high. It takes at least two people per mu to spend two to three days to complete the laying, including the mulching after laying, followed by this kind of Plastic mulch cannot be degraded, and if it is left in the field, it will cause soil pollution. After a few years, it will reduce the yield of crops and even affect the quality of crops. Although the liquid mulch synthesized by inorganic chemistry can achieve the function of plastic mulch, it still cannot be completely degraded and will still be damaged. The field remains, so the technology of organic liquid mulch film that can not only have heat preservation, water retention, degradability, fertility, and insecticidal functions has been plaguing the industry.
