Problems solved by technology

[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 plastic film cannot be recycled due to moisture and damage. It can only be recycled as garbage, which is labor-consuming and time-consuming.

Abstract

The invention discloses a liquid fertilizer mulching film for increasing the moisture utilization rate for corn. The liquid fertilizer mulching film is prepared from the following raw materials in parts by weight: 35-40 parts of sweet potato powder, 18-20 parts of kelp residues, 16-18 parts of modified starch solution, 10-15 parts of coffee beans, 4-6 parts of a composite microbial bacterial agent, 22-25 parts of peanut meal, 28-32 parts of bone meal and a proper amount of water. The liquid fertilizer mulching film disclosed by the invention has a remarkable function in increasing the moisture utilization rate of soil, on one hand, the saturated hydraulic conductivity of soil can be improved, on the other hand, the soil moisture evaporation rate can be inhibited, an excellent water-retaining property can be achieved, the irrigation water amount can be reduced, an excellent energy conservation and emission reduction function is achieved, and meanwhile as the mulching film is made of natural organic matters, the content of nutrients which can be absorbed by soil can be increased when the mulching film is completely degraded, and growth of corn can be promoted.

Description

technical field [0001] The invention relates to the technical field of agricultural mulching film, in particular to a liquid fertilizer mulching film for improving water use efficiency of 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 ...
