preparation example Construction

[0026] The preparation method of organic fertilizer is as follows:

[0027] After the corn stalks were dried, they were pulverized, and then a starter (purchased from Weifang Yihao Biotechnology Co., Ltd. organic fertilizer starter for straws) was added for stacking and fermentation for 6 months, wherein the amount of the starter accounted for 5% of the weight of the straw. During the stacking fermentation process, keep the raw material fermentation temperature not higher than 45°C. After the fermentation is finished, the organic fertilizer can be obtained by drying.

Embodiment 1

[0029] An environment-friendly soil conditioner is prepared by mixing and granulating the following raw materials by weight: 2 parts of EM bacterial agent

Abstract

The invention discloses an environment-friendly soil conditioner and a preparation method thereof, and relates to the technical field of soil improvement. The environment-friendly soil conditioner comprises an EM microbial agent, a natural mineral, volcanic slag, a water-retaining agent and an organic fertilizer, wherein the organic fertilizer is prepared by fermenting, decomposing, drying and crushing plant straws; the natural mineral is a natural porous mineral material. The soil conditioner not only can remarkably improve the soil fertility, but also enables the microbial agent in the soil to be richer. The soil is effectively detoxified through cooperation of mineral elements and the fungicide, and the content of heavy metal in the soil is reduced.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to an environment-friendly soil improver and a preparation method thereof. Background technique [0002] With the continuous development of economy and society and unreasonable planting habits, soil fertility has been seriously degraded, mainly manifested as soil hardening, salinization, acidification, element imbalance, chemical pollution, and loss of organic matter. The result of soil degradation is reduced soil productivity, lower crop quality and yield, and even enrichment of toxic elements. Therefore, how to improve soil fertility, improve soil acidity and alkalinity and soil toxicity, and reduce the spread of soil-borne diseases has become the focus of attention. [0003] The main way to repair soil degradation is to use soil amendments, which can effectively improve soil physical and chemical properties and soil nutrient status, and have a positive impac...
