Compound fertilizer for farmland soil improvement and preparation process thereof

Abstract

The invention discloses compound fertilizer for farmland soil improvement and a preparation process thereof. The compound fertilizer is prepared from the following components in parts by weight: 3-6 parts of a microbial compound inoculant, 6-10 parts of earthworm egg cocoons, 15-20 parts of cow dung, 5-7 parts of compost zymophyte, 20-30 parts of straw, 15-20 parts of mushroom residues, 20-25 parts of rotten figs, 15-20 parts of fresh durian shells, 20-25 parts of a sugar residue mixture, 18-25 parts of bentonite, 15-20 parts of diatomite, 8-12 parts of emulsified asphalt, 10-15 parts of distillers' grains, 5-7 parts of sulfur powder, 8-10 parts of ferrous sulfate and the balance of rice washing water. Earthworm egg cocoons are introduced into soil and can be rapidly hatched into earthworms after the fertilizer is put into use, formation of a soil aggregate structure is promoted, soil breathability is improved, and the soil fertility level is increased. The organic fertilizer improvesthe physical and chemical properties of the soil and enhances the fertilizer retention performance and buffer performance of the soil, the number and activity of soil microorganisms are increased, thesoil temperature is increased, the soil ion exchange rate is increased, and rice washing water is used as a solvent to promote crop growth.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a compound fertilizer for improving farmland soil and a preparation process thereof. Background technique [0002] Soil improvement refers to the use of soil science, biology, ecology and other multidisciplinary theories and technologies to eliminate or prevent unfavorable factors that affect crop growth and cause soil degradation, improve soil properties, increase soil fertility, and create a good soil environment for crops A collective term for a series of technical measures of conditions. Its basic measures include: [0003] 1. Soil water conservancy improvement, such as establishing farmland drainage and irrigation projects, adjusting groundwater level, improving soil moisture status, eliminating and preventing swamp and salinization; [0004] 2. Soil engineering improvement, such as using engineering measures such as land leveling, terraced fields...

AI Technical Summary

Problems solved by technology

[0008] Most of the current compound fertilizers show the impact on crops, and the improvement effect on the soil itself is not obvious. Long-term use of fertilizers will damage the soil aggregate structure, easily cause soil compaction, soil hardening, and affect crop growth.
