Liquid state fertilizer mulching film for supplementing boron elements of corns and preparation method thereof

Abstract

The invention discloses a liquid state fertilizer mulching film for supplementing boron elements of corns and a preparation method thereof. The liquid state fertilizer mulching film is composed of the following raw materials in parts by weight: 12-14 parts of coffee beans, 28-32 parts of fish meal, 4-6 parts of boric acid, 3-6 parts of compound microbial fertilizer, 13-16 parts of modified starch solution, 20-24 parts of boron humate, 32-36 parts of fungus dregs and an approximate amount of water. According to the liquid state fertilizer mulching film provided by the invention, the boron humate, boric acid can supplement the content of boron absorbed in the soil, therefore the normal physiogenesis of the corns can be ensured; meanwhile, the mulching film is further rich in other nutrients necessary for the corns, the soil bulk density can be effectively reduced after the strong adsorbability and heat-shielding performance of the mulching film are applied, and the ground temperature and drought combating can be improved; furthermore, the growth and development of the corns can be promoted, and the yield can be improved.

Description

technical field [0001] The invention relates to the technical field of agricultural plastic film, in particular to a boron-supplemented liquid fertilizer plastic film 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 moistur...
