Embodiment 1

[0036] Taking the production of 1,000 kg of biomass charcoal soil amendment as an example, the specific method is as follows:

[0037] Step 101: subject the biomass charcoal raw material (corn stalks) to pyrolysis under anaerobic conditions at 300 to 700°C for 2 to 3 hours to obtain biomass char for use;

[0038] Step 102: The microbial functional bacteria (Bacillus amyloliquefaciens and Rhizobium) used in the biomass charcoal soil conditioner were cultured in liquid deep layer and high density respectively to obtain the fermentation broth, and ensure that the number of effective viable bacteria per milliliter of the fermentation broth was greater than 1 ×10 11 A

[0039] Step 103: Centrifuge the obtained fermentation broth in a centrifuge at a high speed of 4000 rpm for 10 minutes, and collect bacterial sludge;

[0040] Step 104: Mix the collected bacterial mud (mixed in equal weight ratio) with wheat bran at a mass ratio of 1:30 and absorb, dry at 80°C for 4 hours after adsorption, ...

Embodiment 2

Abstract

The invention discloses a biomass charcoal soil conditioner. The soil conditioner comprises the following raw materials by weight: 40% to 50% of biomass charcoal, 20% to 30% of a functional microbial agent, 10% to 15% of desulfurized gypsum, 5% to 10% of calcium nitrate, 5% to 10% of ground phosphate rock and 1% to 2% of amino acid, wherein the functional microbial agent contains any two selected from the group consisting of bacillus subtilis, bacillus mucilaginosus, bacillus amyloliquefaciens, azotobacter, rhizobia and bacillus megatherium. The biomass charcoal soil conditioner provided by the invention can increase the water-retention rate and air permeability of soil, improve the content of organic matters in the soil, and regulate the pH value of the soil; meanwhile, the adoption of biological means to improve microbial environment of the soil is beneficial for promoting crop growth and high-efficiency nutrient utilization, increases the yield of crops, and improves the quality of the crops. The biomass charcoal soil conditioner provided by the invention effectively utilizes wastes, can improve the soil and enhance soil fertility, and specifically has significant improvement effect on saline alkali land.

Description

technical field [0001] The invention relates to the field of biological improvers, in particular to a biochar soil improver and a preparation method thereof. Background technique [0002] At present, the problem of soil degradation in my country is becoming more and more serious, such as soil compaction, hardening, acidification, erosion, acidification, salinization, chemical pollution, and decline in fertility. According to statistics, the degraded area of ​​cultivated land in my country accounts for about 40% of the total cultivated land area, which seriously restricts the development of my country's agriculture. [0003] The application of soil amendments to remediate degraded soil can effectively improve the physical and chemical properties of the soil and improve soil fertility. As a soil conditioner, biochar has been extensively studied. The carbon content in biochar reaches 70%~90%, which is almost pure carbon and has high stability. It can be buried in the ground fo...
