Example Embodiment

[0058] 1. Preparation of compound microbial agent

[0059] The compound microbial inoculum includes the following components:

[0060] Pseudomonas, Bacillus thuringiensis, Bacillus subtilis, Bacillus licheniformis, Trichoderma and Lactobacillus plantarum.

[0061] The mass ratio among the said Pseudomonas, Bacillus thuringiensis, Bacillus subtilis, Bacillus licheniformis, Trichoderma and Lactobacillus plantarum is 1:1:1:1:1:1.

[0062] The number of effective bacteria in the bacterial liquid of Pseudomonas, Bacillus thuringiensis, Bacillus subtilis, Bacillus licheniformis, Trichoderma and Lactobacillus plantarum is 1 billion / mL.

[0063] Firstly, Pseudomonas, Bacillus thuringiensis, Bacillus subtilis, Bacillus licheniformis, Trichoderma and Lactobacillus plantarum are respectively fermented and cultured to obtain the corresponding bacterial liquid. The fermentation temperature is controlled between 30~37℃, and the fermentation time is 2-3 days, over. Then according to the mass ratio o...

Abstract

The invention discloses a composite modifying agent for restoring farmland polluted soil and a preparation method of the composite modifying agent and relates to the field of modern agriculture. The problem that in an existing polluted soil restoring method, dual restoration functions of soil polluted heavy metal and organic matter cannot be achieved is solved. The composite modifying agent comprises, by weight, 3-9 parts of a composite microbial agent, 40-60 parts of peat soil, 30-50 parts of straw powder, 3-5 parts of cake powder, 0.1-0.3 part of quick lime, 0.2-0.4 part of dipotassium phosphate, 0.5-1.5 parts of ammonium sulfate, 20-40 parts of diatomite, 20-40 parts of humic acid, 20-40 parts of zeolite, 5-15 parts of active carbon, 1-3 parts of sepiolite and 1-3 parts of chitosan. The composite modifying agent can effectively remove heavy metal in the soil and degrade organic pollutants in the soil, has dual restoration functions, cannot cause secondary pollution and can increase the crop yield; and cost is low, the restoration time is short, preparation is easy and convenient, and the restoration effect is good.

Description

technical field [0001] The invention relates to the field of current agricultural technology, in particular to a composite improver for repairing farmland polluted soil and a preparation method thereof. Background technique [0002] Soil is one of the important resources for maintaining our life and the basis for the survival of all living things. The development of modern agriculture has changed the original state of nature. In order to pursue high yields, a large number of chemical fertilizers and pesticides have been used, resulting in the destruction of farmland soil structure, fertility decline, soil environment decline, acidification, salinization, desertification, hardening and airtightness, and serious pests and diseases. In addition, industrial production, oil extraction, transportation, sewage irrigation, agricultural sludge, livestock and poultry breeding, and residential life also produce a large amount of heavy metals and organic pollutants, which have seriously...
