Problems solved by technology

[0003] 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 an improved acidified soil water-retention compound fertilizer and a preparation method thereof. The improved acidified soil water-retention compound fertilizer is prepared from, by weight, 20-23 parts of urea, 3-4 parts of an EM fungicide, 20-22 parts of biogas residues, 6-8 parts of silkworm excrement, 8-10 parts of lignite, 18-22 parts of sodium humate, 12-15 parts of potassium dihydrogen phosphate, 12-13 parts of chitosan, 8-10 parts of smoke slag, 20-30 parts of tea tree waste, 1-2 parts of antibiotics, 6-8 parts of bentonite, 4-6 parts of boron mud, 6-8 parts of blast furnace slag, 6-9 parts of polylactic acid, 8-12 parts of rosin pentaerythritol ester, 0.5-1 part of N,N-methylene bisacrylamide and a proper amount of water. The boron mud, the bentonite and other ingredients are added to the improved acidified soil water-retention compound fertilizer, alkaline ingredients are increased, meanwhile the power of hydrogen is isolated and buffered, the acid-base equilibrium of soil is regulated, accordingly acidified soil can be effectively improved, and soil fertility is improved.

Description

technical field [0001] The invention relates to the technical field of slow-release fertilizers, in particular to a compound fertilizer for improving acidified soil water retention and a preparation method thereof. Background technique [0002] At present, there are generally three kinds of agricultural fertilizers in the Chinese market: one is chemical raw material fertilizer, one is organic fertilizer, and the other is chemical raw material and organic fertilizer mixed fertilizer; the disadvantage of chemical raw material: long-term use will cause land soil compaction, Affect the growth of crops, resulting in a gradual reduction in production; the disadvantages of organic fertilizers are: the nutrients required by plants are insufficient to meet the needs of crop production; they affect crop yields; the disadvantages of mixed fertilizers: the organic matter and total nutrients in the fertilizer formula are contradictory, so High and low, if the organic matter content is to...
