Embodiment 1

[0024] This embodiment provides a kind of soil structure conditioning agent that is applicable to pasture, is mixed by 65% ​​biological nano charcoal, 5% linear polyacrylamide, 5% sodium carboxymethyl cellulose, 15% nano-scale bentonite and 10% microbial bacterial agent composition. Among them, bio-nano charcoal is composed of 50% coconut shell charcoal and 50% bamboo shoot shell charcoal. The microbial bacterial agent is any one of Bacillus subtilis, Bacillus licheniformis, Bacillus sporogenes, Bacillus megaterium, Bacillus amyloliquefaciens and Trichoderma harzianum.

Embodiment 2

[0026] The present embodiment provides a kind of soil structure conditioning agent that is applicable to grassland, is made up of 60% biological nano charcoal, 5% linear polyacrylamide, 5% sodium carboxymethyl cellulose, 20% nano-scale bentonite and 10% microbial agent , wherein, bio-nano charcoal is composed of 40% coconut shell charcoal and 60% bamboo shoot shell charcoal. The microbial agent is Bacillus subtilis, Bacillus licheniformis and Bacillus lateral sporosum.

Embodiment 3

[0028] The present embodiment provides a kind of soil structure conditioning agent that is applicable to pasture, is made up of 70% biological nano charcoal, 3% linear polyacrylamide, 2% sodium carboxymethyl cellulose, 17% nano-scale bentonite and 8% microbial agent , wherein, bio-nano charcoal is composed of 60% coconut shell charcoal and 40% bamboo shoot shell charcoal. Microbial agents are Bacillus subtilis, Bacillus licheniformis, Bacillus lateral sporosum, Bacillus megaterium, Bacillus amyloliquefaciens and Trichoderma harzianum.

[0029] The biological nano-carbon used in the present invention is mixed in proportion by coconut shell and bamboo shoot shell, through high-temperature carbonization, water vapor activation, grinds to carbon powder particle size≤60nm gained.

Abstract

The invention belongs to the field of soil environment treatment and particularly relates to a soil structure conditioner suitable for a meadow. The soil structure conditioner is prepared from 60-70%of nano biochar, 1-5% of linear polyacrylamide, 1-5%of sodium carboxymethylcellulose, 10-20%of nano bentonite and 5-10% of a microbial agent. The conditioner is a novel soil structure conditioner compounded by biological and linear high-molecular polymers, can remarkably improve a farmland soil structure, increase the soil water content, reduce the soil bulk density, strengthen the microbial activity of soil, improve enzyme activity, increase the trace element content of the soil, remarkably improve the biological activity and remarkably promote the growth of crops. It is shown according to analpine meadow practice effect of the Qinghai-Tibet Plateau that degraded meadow soil can be remarkably improved and the growth of kobresia humilis can be promoted by applying the soil structure conditioner.

Description

technical field [0001] The invention belongs to the field of soil environment management, and in particular relates to a soil structure conditioner suitable for pastures. Background technique [0002] Soil is the foundation of agricultural planting, and a healthy soil environment is the foundation of agricultural development. But at present, a considerable part of the land in our country has heavy soil compaction that causes less air, poor permeability or serious desertification and salinization of the soil, so the research and use of soil conditioners are becoming more and more common. [0003] Soil conditioner is composed of agricultural water-retaining agent and natural peat rich in organic matter and humic acid or other organic matter as the main raw materials, supplemented by biologically active ingredients and nutrient elements, and has three remarkable functions of water retention, fertilization and ventilation. Conditioning performance, can break soil compaction, lo...
