Problems solved by technology

However, most of the existing arsenic-contaminated soil remediation or safe utilization technologies are the application of passivating agents or engineering measures, which not only consume a lot of manpower and material resources, but also have unknown effects on soil properties. There is still a certain degree of difficulty

Abstract

The invention relates to a seed coating agent for reducing arsenic absorption by crops and a preparation method thereof. The preparation method comprises the steps of preparing an arsenic-containing solid medium, preparing a culture solution, preparing a trichoderma aculeatus chlamydospore powder, and preparing a seed coating agent. The seed coating agent of the invention improves seed vigor, has a certain promoting effect on seed germination, and increases the germination rate by 1-2 percentage points. The coating treatment of the seed coating agent of the present invention can block the accumulation of arsenic in crops, improve the tolerance of crops to soil arsenic, greatly reduce the absorption of arsenic by crops, effectively promote the growth of these seeds, increase their yield, and promote crop safety. Production.

Description

【Technical field】 [0001] The invention belongs to the technical field of plant protection. More specifically, the present invention relates to a seed coating agent for reducing arsenic absorption by crops, and also relates to a preparation method of the seed coating agent for reducing arsenic absorption by crops. 【Background technique】 [0002] my country is one of the countries with serious arsenic pollution in the world. According to the "National Soil Pollution Survey Bulletin" jointly issued by the Ministry of Environmental Protection and the Ministry of Land and Resources in April 2014, the rate of arsenic pollution in my country's soil is 2.7%. Most of them are medium and light pollution. Although the proportion of the total soil area is not high, the polluted areas are relatively concentrated in mining areas, smelting areas, and some suburban areas. The points where the arsenic content in the soil exceeds the standard can reach more than 40% or even higher, and the ar...
