Problems solved by technology

At present, most of the relevant microbial soil remediation agents that appear on the market are isolated from single bacteria and then produced in laboratories and factories before entering the land. The price is high, the professionalism is strong, and the fungus is single, so it is difficult to promote

Embodiment

[0016] A kind of microbial soil remediation agent, the raw material of this remediation agent comprises the following proportions by weight: 500 kilograms of broad-leaved tree fallen leaves and crop straw, 200 kilograms of peat soil, 300 kilograms of bran, 10 kilograms of urea, 5 kilograms of dipotassium hydrogen phosphate, probiotic 200 kg of bacterial strains.

[0017] The probiotic strains are collected by natural fermentation of the sterilized mixture of bran and soybean meal on the fallen leaves on the ground of the original ecological broad-leaved forest.

[0018] The preparation method of described a kind of microbial soil remediation agent comprises the following steps:

[0019] 1) Weigh 200 kg of the mixture of bran and soybean meal and mix it with water, pack it in sacks and sterilize according to the sterilization method for producing mushroom raw materials.

[0020] 2) Cool the sterilized mixture in step 1) to 35°C, and spread it on the fallen leaves of the broad-...

experiment example

[0024] Experimental subjects: Two cucumber protected areas with serious soil compaction and serious soil-borne diseases in Xian'an District, Xianning City and two tomato greenhouses with excessive pesticide residues in Anjiang Town, Huaihua City, divided into control cucumber protected areas without using microbial soil remediation agents And the experimental cucumber protection field using microbial soil remediation agent, the control tomato greenhouse without microbial soil remediation agent and the experimental tomato greenhouse using microbial soil remediation agent.

[0025] Experimental method and time: traditional organic fertilizers and planting methods were used in contrast to cucumber protected land and contrasted tomato greenhouses, and what the experimental tea cucumber protected land and experimental tomato greenhouses used was the microbial soil remediation agent of the present invention, observed and tested in the crop growth cycle Record the conditions of variou...

Abstract

The present invention provides a microbial soil repair agent with effects of repair of hardening soil and serious soil-borne disease soil, wherein probiotic floras in nature are collected through a simple method and are subjected to expanded culture so as to obtain the microbial soil repair agent. According to the present invention, the microbial soil repair agent has high organic substance content and high activity beneficial microbial flora; wit the microbial soil repair agent, the flora balance between the beneficial microorganisms and the soil-borne disease microorganisms in the soil can be effectively maintained, and the pesticide residues in the soil can be rapidly degraded; and the raw materials of the microbial soil repair agent comprise, by weight, 500 kg of broadleaf tree deciduous leaves and crop straws, 200 kg of turfy soil, 300 kg of bran, 10 kg of urea, 5 kg of dipotassium hydrogen phosphate, and 200 kg of probiotic bacteria.

Description

technical field [0001] The invention relates to a microbial soil restoration agent, which belongs to the new technology of ecological agriculture. Background technique [0002] In recent years, the extensive use of chemical fertilizers and the neglect of farm organic fertilizers have led to soil compaction and degradation, while continuous cropping in many economic crop production areas has caused serious soil-borne diseases in the soil, and excessive spraying of pesticides has resulted in a large number of disease bacteria and pesticides remaining in the soil , severely polluted the cultivated land. In the context of a lot of Chinese people with little land, the sustainable production capacity of soil is the basic guarantee for China's food security, and the state attaches great importance to the restoration of polluted soil. At present, most of the relevant microbial soil remediation agents that appear on the market are isolated from single bacteria and then produced in ...
