Corn-used liquid fertilizer mulching film for reducing consumption of chemical fertilizers and preparation method of corn-used liquid fertilizer mulching film

Abstract

The invention discloses a corn-used liquid fertilizer mulching film for reducing the consumption of chemical fertilizers. The corn-used liquid fertilizer mulching film comprises the following raw materials in part by weight: 16-19 parts of malt roots, 9-13 parts of coffee beans, 13-17 parts of potassium humate, 2-5 parts of a compound microbial agent, 14-16 parts of a modified starch solution, 34-36 parts of pig manure, 26-28 parts of furfural residue, and a proper amount of water. The raw materials of the liquid fertilizer mulching film adopt a fermented liquid of the malt roots and the furfural residue, as well as potassium humate and the like, and contain a great amount of carboxyl, hydroxyl and other functional groups, thereby playing the roles of complexation and chelation with indissolvable metal ions in soil after the liquid fertilizer mulching film sprayed, and making non-absorbable nutrients for corn useable to cooperate with added organic nutrients in the mulching film. Therefore, the consumption of the chemical fertilizers in the corn growing process is reduced greatly, that is, not only the cost, but also damage of the chemical fertilizers to the soil is reduced.

Description

technical field [0001] The invention relates to the technical field of agricultural mulch, in particular to a liquid fertilizer mulch for corn that reduces the amount of chemical fertilizer used 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 excellen...

[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.
