Net distributed type ecology restoration method specially used for pesticide organic matter polluted soil

Abstract

The invention discloses a net distributed type ecology restoration method specially used for pesticide organic matter polluted soil. The net distributed type ecology restoration method specially used for pesticide organic matter polluted soil is capable of improving restoration single performance in conventional microbe ecological restoration. According to the method, a plurality of microbial agents are taken as raw materials, the synergetic mutualism co-metabolism of the microbial agents is capable of increasing the efficiency of microbial agents in restoration of soil ecological system and degradation of pesticide organic pollutants, and the effect on restoration of soil pollution caused by pesticide organic matters is especially obvious; at the same time, an adopted nutrient and active humic acid are capable of improving soil, improving beneficial microbe living environment, and promoting beneficial microbe growing and breeding, so that the effect of the microbial agents is improved, and soil restoration time is shortened; a special net distribution device is adopted, so that the microbial agents can be dispersed in every spots in soil to be restored, and the penetration effect and restoration effect of the microbial agents in soil are promoted; and in addition, resistant plants such as Eichhornia crassipes is planted in the pesticide organic matter polluted soil, so that the improvement effect on pesticide organic matter pollution is better.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, and more specifically relates to a net-deploying ecological remediation method for soil contaminated by pesticide organic matter. Background technique [0002] Chemical pesticides play a huge role in the prevention and control of crop diseases, insect pests and weeds to eliminate sanitary pests and diseases, and promote the development of modern agriculture due to their advantages of quick effect, control spectrum, stable properties, convenient transportation, and low price. Organophosphorus pesticides are still the most used category of pesticides because of their many varieties, high efficacy, and broad-spectrum prevention and control. They have played a pivotal role in agricultural production. More than half of the total production and consumption. However, organophosphorus pesticides are highly toxic. After long-term and large-scale use, their residues on crops will cau...

Problems solved by technology

However, the use of microorganisms to degrade pesticides has high specificity, and often one microorganism cannot degrade multiple types of pesticides at the same time, and the degradation rate is slow. Contaminated soil usually has multiple pesticide residues coexisting, so the degradation and repair effect of a single microbial preparation is relatively low. Poor, and due to the current restoration methods of microbial preparations, most of them use the method of turning the soil and splashing. On the one hand, it consumes a lot of manpower and material resources. The infiltration is not purposeful, and the infiltration capacity is limited, so once the soil with serious pollution appears, it will even need to be overturned several times, which will significantly increase the cost of remediation, and at the same time, it will not be able to exert the maximum effect of microbial agents, or achieve the same level of remediation. The consumption is much higher than the theoretical amount, resulting in waste of microbial preparations
