Lumbrukinase-based mineral soil remediation fertilizer and preparation method thereof

Abstract

The invention discloses a lumbrukinase-based mineral soil remediation fertilizer and a preparation method thereof. The fertilizer comprises mineral soil, plant straws and animal manure, wherein the raw materials are proportioned by weight; the mineral soil accounts for 35 to 50 percent; the plant straws accounts for 15to 20 percent; the animal manure accounts for 30 to 50 percent; the mineral soilcomprises following components in parts by weight: 5-12 parts of diatomite, 7-14 parts of zeolite, 5-8 parts of sepiolite, 15-21 parts of calcium carbonate, and 5 to 9 parts of sodium alginate; the plant straws comprise the following components in parts by weight: 12-20 parts of rice straws, 15-18 parts of wheat straws, 5-8 parts of soybean straws and 10-15 parts of corn straws, and the animal manure comprises the following components in parts by weight: 15-20 parts of livestock manure, 10-15 parts of poultry manure and 20-30 parts of earthworms. The mineral soil, the plant straws and the animal manure are mixed to prepare the soil remediation fertilizer, the soil activity is effectively improved, and the remediation capacity is efficient.

Description

technical field [0001] The invention relates to the technical field of soil remediation fertilizer, in particular to a lumbrokinase-based mineral soil remediation fertilizer and a preparation method thereof. Background technique [0002] Soil remediation, as the name implies, is to transform toxic and harmful pollutants into harmless substances, improve the soil environment, and protect the healthy growth of crops. Soil fertility includes soil biological, physical, and chemical fertility, among which microorganisms are the main component of soil fertility. Microorganisms living in the soil can promote the production of organic matter, improve soil vitality, maintain the energy required for the growth of crop roots, increase the content of organic matter in the soil, increase the microbial activity of the soil, and promote crop growth. [0003] The existing preparation method of soil remediation fertilizer cannot directly change the soil, the heavy metal elements in the soil...

AI Technical Summary

Problems solved by technology

[0003] The existing preparation method of soil remediation fertilizer cannot directly change the soil, the heavy metal elements in the soil cannot be removed, and the soil cannot be repaired directly and quickly, and the soil may agglomerate after a long time. Therefore, here we propose a lumbrokinase-based Material soil remediation fertilizer and preparation method thereof
