Problems solved by technology

[0003] The main cause of land degradation is: in order to pursue high efficiency, high yield, and high return, people apply too much chemical fertilizer to the land, making the land more and more barren. The organic matter in the medium gradually disappears, the land is hard and hardened, and the virtuous cycle of the land is destroyed, forming a serious degradation of the ecological environment of a large area of ​​land

Embodiment 1

[0043] The organic waste with a solid content greater than 25% enters the production line that is fully sealed and has negative pressure odor elimination. Sterilization machine, run for 3-5 minutes, sterilize and initially dry, and then enter the mixer, add beneficial bacteria to the organic waste in the mixer, stir evenly, enter the aerobic fermentation program. After fermentation, heating up, aeration, mechanized turning, and running for 100-130 hours, the organic waste is matured, the smell basically disappears, and the solid content is increased to 70%. The organic waste is sent to the tunnel microwave dryer by the conveyor, and the The water content is reduced to 8%-15%, and the organic waste is sent to the pulverizer through the conveyor, crushed to 40 mesh, and then enters the homogeneous mixer to add the biochar powder soaked in the beneficial bacteria water for 24 hours, and homogeneously stirs After 6-8 minutes, measure, bag and store.

Embodiment 2

[0045] Add beneficial bacteria to the organic waste sterilized by microwave, and then enter the anaerobic fermentation process after stirring evenly. Discharge after 1 hour, check the PH value, PH value 6.5-7.5 is good fermentation, PH value is more than 8 or less than 6, use wood vinegar and lime water to adjust the pH value to 6.5-7.5, and then sent to the tunnel by the conveyor Microwave dryer, reduce the moisture to 10%-15%, send the organic waste to the pulverizer through the conveyor, pulverize to 60 mesh, enter the homogeneous mixer and add biochar powder soaked in beneficial bacteria water for 24 hours , homogeneously stirred for 8-10 minutes, then measured, bagged and stored.

[0046] The process of using degraded land restoration agent is as follows:

[0047] Degraded land restoration agent is suitable for furrow sowing of degraded land by walking agricultural machinery or special agricultural machinery. The dosage of 1000kg-2000kg per mu in the first year can resto...

Abstract

The present invention relates to a kind of degraded soil recovering preparation and belongs to the field of degraded soil recovering technology. The degraded soil recovering preparation is prepared with organic waste, biological charcoal and probiotics as material, and through microwave sterilization, fast microbial fermentation and microwave stoving of organic waste, and the mixing of organic waste, biological charcoal and probiotics. The present invention prepares degraded soil recovering preparation with organic waste to increase the organic matter content in the soil and raise the fertility of soil, biological charcoal to adsorb and lock chemical pollutant and purify soil, and probiotics to improve soil structure stably, so as to recover the ecological environment of oil for organic food production.

Description

Technical field: [0001] The invention relates to a degraded land restoration agent and belongs to the technical field of degraded land restoration agents. technical background: [0002] At present, land degradation is generally serious, and land degradation refers to the degradation of land ecological environment. [0003] The main cause of land degradation is: in order to pursue high efficiency, high yield, and high return, people apply too much chemical fertilizer to the land, making the land more and more barren, and the barren the land, the more the use of chemical fertilizers increases, making the land The organic matter gradually disappears, the land is hard and hardened, and the virtuous cycle of the land is destroyed, resulting in serious degradation of the ecological environment of large areas of land. [0004] The land is degraded due to excessive application of chemical fertilizers, and the land is polluted by chemical substances. The fish, meat, eggs, poultry, m...
