Problems solved by technology

The disadvantage of this technology is that the microbial agent has poor dispersibility and is inconvenient to use; the use of furrow application of soil remediation preparations cannot uniformly improve the physical and chemical properties of the soil
There is also a soil improvement and moisture retention agent (CN 1597844A) using acrylic acid as the main component, but acrylic acid is a chemical preparation, which not only has a higher cost but also has potential secondary pollution risks, and does not have the effect of increasing the soil aggregate structure

Embodiment 1

[0014] Example 1, 0.5% of silanol non-ionic surfactant is made into 2% aqueous solution, mixed evenly with biomass pyrolysis semi-coke, and then crushed into a fine powder of about 0.5mm by a stick mill, and then 5% microbial fertilizer solution containing bacillus, rhizobia, autogenous nitrogen-fixing bacteria and phosphorus bacteria is mixed evenly with the modified biological semi-coke powder, the microbial fertilizer solution is loaded on the modified biological semi-coke powder, and dried at low temperature; loading The biological semi-coke powder of the microbial fertilizer is evenly mixed with 20% ammonium humate, and sealed and packaged to obtain a secondary salinization and hardening soil conditioner.

Embodiment 2

[0015] Example 2, 1% glycerin is made into a 30% aqueous solution, sprayed and mixed with biomass pyrolysis semi-coke evenly, and then crushed into a fine powder of about 0.8mm by a stick mill, and then 10% of the solution containing Saccharomyces cerevisiae The microbial fertilizer solution and the modified biological semi-coke powder are mixed evenly, the microbial fertilizer solution is loaded on the modified biological semi-coke powder, and dried at low temperature; the biological semi-coke powder loaded with microbial fertilizer and 25% molasses fermentation product The dry powder is mixed evenly, sealed and packaged, and the secondary salinization and compaction soil conditioner is obtained.

[0016] When using, before the autumn of the previous year or the spring of the current year, sprinkle the secondary salinization and compaction soil conditioner evenly on the surface of the secondary salinization or compaction soil at a rate of 20Kg / mu, and use a rotary tiller to mi...

Abstract

The invention discloses a secondarily salinized and hardened soil conditioning agent prepared from biological semi-coke powder and a utilization method thereof. A preparation method of the secondarilysalinized and hardened soil conditioning agent includes: grinding wetting agent modified semi-coke powder, uniformly mixing with 3%-20% of microbial bacterial manure and loading, uniformly mixing with 10%-30% of humic acid, and sealing in packages to obtain the secondarily salinized and hardened soil conditioning agent. Before use, the secondarily salinized and hardened soil conditioning agent isuniformly sprayed on surfaces of secondarily salinized and hardened soil before soil preparation in the last autumn or in the spring of the same year, and a rotary cultivator is utilized to mix the secondarily salinized and hardened soil conditioning agent with the soil, so that uniform mixing of the secondarily salinized and hardened soil conditioning agent in a plough layer is realized, and a green and low-cost way is provided for improvement of degraded soil.

Description

1. Technical field [0001] The biological semi-coke powder prepared by the invention provides a secondary salinization and compaction soil conditioner and its use method, which relate to the restoration and treatment of degraded soil, and in particular to the restoration of secondary salinization and compaction soil. 2. Background technology [0002] Due to the important role of protected cultivation (mainly plastic greenhouses, solar greenhouses and mulching technology) in the off-season and cross-regional planting of vegetables and other important economic crops in my country, protected agriculture has been widely promoted and applied throughout the country , the cultivation area has grown from 7,200 hm2 in 1981 to 2.1 million hm2 today, accounting for 70% of the world's protected cultivation area, and has become the country with the largest protected cultivation area and total output in the world. However, what is incompatible with the rapid development of protected cultiva...
