The high-fiber organic matter, such as rice straw, wheat straw, bagasse, rice, etc., is added to the composted organic raw materials, and the soil and microorganisms are simultaneously ploughed into the soil to obtain a good soil improvement effect. High fiber provides the microbial habitat microbes and is harvested by composting and chemical fertilizers to produce the required nutrients, creating a good soil "biological phase". Microorganisms can secrete a large amount of polysaccharide mucus in the soil, promote the granulation of soil, and slowly ferment in the soil to loosen the soil.
Straw fiber can help soil water absorption, porosity and drainage, and directly promote the soil "physical phase". Soil microbes inhabit and reproduce and secrete a large number of biochemical substances, including active enzymes, antibiotics, bacteriostatics, phosphorus-dissolving substances, vitamins, growth hormones, etc., to improve the "biochemical phase" of the soil. Simultaneous input of straw fiber, organic and inorganic fertilizers and strains can promote the reproduction of beneficial microorganisms and simultaneously improve the balance of soil “biological phaseâ€, “physical phase†and “biochemical phase†to achieve the effect of improving soil improvement.
In the rainy season, crops rot due to water in the roots. In fact, the main culprits of rotten roots are not simply water but hydrogen toxins such as hydrogen sulfide, ammonia and methyl mercaptan. Some of these harmful gases are produced by protein decomposition and deamination of nitrogen fertilizer. In addition, some hydrogen sulfide is produced by anaerobic bacteria in the soil, such as ammonia produced by improper fertilization of sulphuric acid, which is harmful to living things and ambient air. In the state of reproduction, these gases are dissolved in water and contact the roots, which will poison the tissues and cause rotten roots. At the same time, the disease bacteria will invade the roots and cause various diseases, falling flowers and fruit falling.
In the soil microbial group, such as photosynthetic bacteria, it can be converted into monosaccharides and sulfates by using hydrogen sulfide, carbon dioxide, water and sunlight or heat under the conditions of flooding and anoxic, and sulfate can be synthesized with ammonia. It is ammonia sulfate and becomes a nutrient for plants. Not only the production of glucose, but also the toxicity of hydrogen sulfide and ammonia disappeared from the muddy water, and they can be turned into useful nutrients. This is a great contribution to soil microbes. (
