Completely degradable liquid fertilizer mulching film for corn and preparation method thereof

Abstract

The invention discloses a completely degradable liquid fertilizer mulching film for corn and a preparation method thereof. The mulching film is prepared from the following raw materials in parts by weight: 35-38 parts of wheat bran, 15-18 parts of a modified starch solution, 24-26 parts of rice chaff, 10-14 parts of coffee beans, 1-3 parts of polyving akohol, 2-5 parts of a compound microorganism bacterium agent, 19-21 parts of lobster powder and a moderate amount of water. The raw materials adopted by the liquid fertilizer mulching film are all degradable; the molecular chain of the added polyving akohol contains a large amount of side-hydroxide radical, wherein side-hydroxide radical is easy to dissolve in water and can bond with natural products, inorganic matters, and the like, so that the formed mulching film is high in intensity, can be degraded into CO2 and H2O in a wet environment within 2-3 months, and is free of environmental pollution; the organic fermentation liquor in the mulching film can improve soil fertility and promote the growth of corn.

Description

technical field [0001] The invention relates to the technical field of agricultural mulch, in particular to a fully degradable liquid fertilizer mulch for corn and a preparation method thereof. Background technique [0002] Mulch film has the functions of heat preservation, water retention, and frost protection for crops. The application of mulch film technology has greatly improved and increased the yield and benefit of crops. However, traditional mulch film is a synthetic polymer compound that is almost non-degradable in the natural state. , If it is not treated after use, it will cause great pollution to the soil environment and affect the growth of crop roots. However, the treated mulch film cannot be recycled due to moisture and damage. It can only be recycled as garbage, which is labor-intensive and time-consuming. [0003] For this reason, the inventors provided a liquid fertilizer mulch film for corn, which not only has the excellent water and moisture retention perf...
