Embodiment 1

[0034] A preparation method of a nanometer soil restoration conditioner, comprising the steps of:

[0035] (1) At a temperature of 55°C, dry the wheat straw, wheat straw, corngrass and emperor bamboo grass until the water content of the wheat straw, wheat straw, corn grass and emperor bamboo grass is ≤20%;

[0036] Wherein, the mass ratio of wheat straw, wheat straw, corn grass and emperor bamboo grass is 1:1:2:3;

[0037] (2) Grinding the dried wheat straw, wheat straw, corngrass, and emperor bamboo grass into particles with a particle size of 10mm, and then mixing them uniformly to form a mixture;

[0038] (3) Mix the mixture, manure, EM bacteria and water at a mass ratio of 10:1:0.1:1, and then ferment anaerobically at a temperature of 50°C for 32 hours to obtain the first raw material;

[0039] Then raise the temperature of the first raw material to 90°C, keep it warm for 10 minutes, and then cool down to 30°C;

[0040] (4) The first raw material and water are mixed acco...

Abstract

Theinvention discloses a preparation method of a nano soil remediation conditioner. The preparation method disclosed by the invention has the beneficial effects that 1, wheat stalks, barley stalks, teosinte and pennisetum hydridum are selected, the yield is high, and the cost is low; meanwhile, a large amount of plant fiber can be provided, and soil nutrients can be effectively fixed; 2, mixing the wheat stalks, the barley stalks, the teosinte and the pennisetum hydridum with EM (Effective Microorganisms) bacteria and barnyard manure, nutrients which can be easily absorbed by plants can be formed by adopting an anaerobic fermentation method, and the yield of crops can be greatly increased; 3, zeolite, pulverized fuel ash, coal cinder and kaolin are mutually matched, so that metal cadmium in soil can be effectively adsorbed, and an effect of reducing thecontent of cadmium in the soil can be further achieved.

Description

technical field [0001] The invention relates to a passivation heavy metal, in particular to a preparation method of a nanometer soil repair conditioner. Background technique [0002] With the rapid development of economy and industry, the extensive application of chemical fertilizers and pesticides, the exploitation of mines and oil fields, and the discharge of enterprises such as petrochemical, pesticide and pharmaceutical production have led to the continuous deterioration of soil pollution. Among them, heavy metal pollution in soil has become a problem that cannot be ignored. These heavy metal pollution will not only lead to crop yield reduction, but also remain in agricultural products, and then enter the human body, causing major hidden dangers to people's health. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Anot...
