Earthworm amino acid stable organic-inorganic soil conditioner and processing technology thereof

Abstract

The invention especially relates to an earthworm amino acid stable organic-inorganic soil conditioner and a processing technology thereof, belonging to the field of soil conditioners. The soil conditioner comprises an earthworm amino acid solution, urea, earthworm cast, humic acid, fly ash and a long-acting agent. The composition of the above-mentioned components by mass is that 20 to 50 parts of the earthworm amino acid solution containing 90% of water, 15 to 50 parts of urea containing 46.3% of nitrogen and 1% of water, 10 to 36 parts of earthworm cast containing 1% of nitrogen, 25% of water and 42% of organic matters, 5 to 25 parts of humic acid containing 80% of organic matters and 20% of water, 1 to 35 parts of fly ash containing 8% of organic matters and 8% of water and 0.5 to 13 parts of the long-acting agent containing 40.4% of a digestion inhibitor and 16.28% of a urease inhibitor. The urease inhibition rate and digestion inhibition rate of the soil conditioner provided by the invention exceed requirements prescribed in international stability standard HG/T4135-2010; and the soil conditioner has increased nitrogen content, good stability effect and a high utilization rate, is rich in calcium, magnesium, silicon and 18 amino acids favorable for crop growth, and provides effective guarantee for high and stable yield of crops.

Description

technical field [0001] The invention belongs to the field of soil conditioners, and in particular relates to an organic-inorganic soil conditioner with stability of earthworm amino acid and its processing technology. Background technique [0002] Soil is the foundation of agriculture and the most basic means of production for human beings. Land resources are not only limited, but also there is a considerable proportion of soil with obstacles due to soil-forming factors or human factors. However, the poorness of the land has not attracted enough attention. At present, the increase in agricultural production in various countries in the world is still dominated by the application of large amounts of chemical fertilizers, while the utilization rate of chemical fertilizers has dropped significantly. Increased application of chemical fertilizers has caused soil compaction, desertification, and serious soil fertility. decline. Typically, these barrier soils are difficult to use, ...

AI Technical Summary

Problems solved by technology

[0004] At present, although there are all kinds of soil conditioners on the market, these soil conditioners often do not contain nitrogen. Therefore, soil conditioners must be applied with nitrogen fertilizers. In addition, the stability of soil conditioners is poor, resulting in low fertilizer utilization.
