High-water conservation liquid fertilizer mulching film for maize and preparation method of high-water conservation liquid fertilizer mulching film

Abstract

The invention discloses a high-water conservation liquid fertilizer mulching film for maize. The high-water conservation liquid fertilizer mulching film is prepared from the following raw materials by weight: 23 to 26 parts of leaf mold, 2 to 4 parts of sodium formate, 3 to 5 parts of composite microbial agents, 33 to 37 parts of plant ash, 24 to 26 parts of a modified starch solution, 13 to 15 parts of coffee berries, 38 to 42 parts of castor cake, and a proper quantity of water. Through the adoption of the high-water conservation liquid fertilizer mulching film, a tremellose thin film can be formed to connect soil particles together and further form a polymolecular reticular film; the polymolecular reticular film can seal surface soil pores to prevent soil moisture from volatilizing, but allows moisture to permeate into soil, thereby being excellent in water conservation performance; moreover, after degradation, the raw materials of the mulching film can improve the contents of soil nutrients to supplement loss of part of functional elements of an applied chemical fertilizer, and improve the growth capability of maize.

Description

technical field [0001] The invention relates to the technical field of agricultural mulch, in particular to a liquid fertilizer mulch for corn with high water retention 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 reten...
