The compound microbial agent prepared by this invention can not only change the soil nutrient structure and the distribution of microbial communities in the soil, but also change the content of active ingredients in the rhizome of Ligusticum chuanxiong, thereby significantly promoting the growth of Ligusticum chuanxiong rhizome.

The present invention provides an application of a heterotrophic nitrifying bacteria agent combined with nitrogen fertilizer in improving soil habitat and promoting the growth of young apple trees. The heterotrophic nitrifying bacteria agent is composed of pure cultured bacterial strains H7-5, H9-7 and H11-4, H7-5 is Microbacterium, H9-7 is Pseudomonas, H11-4 is Arthrobacter, and the nitrifying bacteria agent can improve the microecological environment of fruit tree soil and promote the growth of fruit trees. The present invention isolates 26 strains of dominant nitrifying bacteria from apple orchard soil, and after screening, the bacterial strains with good nitrification activity are made into a mixed agent, which can change the distribution of soil microbial populations and nutrient supply conditions after combining soil nitrogen fertilizer treatment, and affect the growth of young apple trees. The soil habitat and the growth of young apple trees show that the inoculation of the agent with nitrate nitrogen fertilizer can increase the soil nitrate nitrogen, available potassium content and pH value, change the diversity characteristics of the soil bacterial population, and show a positive effect on the growth-promoting effect of young apple trees.

The invention discloses a saline-alkali soil modifier and a preparation method and application thereof, and belongs to the field of saline-alkali soil improvement, and the preparation method comprises the following steps: S1, extracting fulvic acid mixed liquor from weathered coal in the Nouth Lake of Hami Da in Xinjiang; s2, the fulvic acid mixed solution is graded to obtain F1-grade fulvic acid-F4-grade fulvic acid, and the molecular weight of the F1-grade fulvic acid is 1t; 500 is smaller than or equal to F2-grade fulvic acid molecular weight 1t; the molecular weight of F3-grade fulvic acid is larger than or equal to 1000 and smaller than or equal to 2500, and the molecular weight of F4-grade fulvic acid is gt; 2500: F1-grade fulvic acid or / and F2-grade fulvic acid is the saline-alkali soil modifier. The modifier can obviously improve the physical and chemical properties of soil, also has a certain increase in the contents of soil nutrient organic matters, hydrolytic nitrogen quick-acting phosphorus and quick-acting potassium, and has significant effects on improving the seedling emergence of crops, promoting the growth of the crops and increasing the yield of the crops.

The invention aims to provide a method for providing high-slope farmland potato soil nutrients and increasing the yield, so that the problems of environmental pollution, soil fertility reduction, threat to food safety and the like caused by excessive application of chemical fertilizers are solved. The phosphate tailing powder is used as the soil conditioner and is matched with the chemical fertilizer for application, pollution caused by application of the chemical fertilizer is reduced, and meanwhile the influence of the phosphate tailing powder on soil improvement, absorption and accumulation of plants on nitrogen, phosphorus and potassium and the yield of potatoes is researched. Test results show that in the potato tuber forming period, the tuber expanding period and the starch accumulation period, the optimized fertilization and the phosphate tailing powder are cooperatively applied, and compared with local conventional fertilization treatment, the pH value, the total phosphorus content and the rapidly available potassium content of soil are effectively increased.

The bacillus altitudinis ZXY01 is classified and named as bacillus altitudinis, and the preservation number of the bacillus altitudinis ZXY01 is CGMCC (China General Microbiological Culture Collection Center) No.36684. The bacillus altitudinis ZXY01 provided by the invention has a good potassium-dissolving function, the research of soil culture experiments proves that a bacterial liquid prepared from the bacillus altitudinis ZXY01 can be directly used as an agricultural microbial potassium-dissolving bacterial agent fertilizer, and due to the direct action of the bacillus altitudinis ZXY01, the potassium-dissolving effect of the bacterial liquid is greatly improved. In the plant planting process, the content of rapidly available potassium in the soil can be effectively increased, the soil fertility is enriched, the forms of a non-exchange state and a mineral state of potassium in the soil are further changed, a new way is provided for a novel agricultural microbial potassium-dissolving bacterial agent fertilizer, and the application prospect is wide.

This invention relates to a bio-fertilizer based on mushroom residue and tailings, its segmented inoculation preparation method, and its application. Mushroom residue-degrading bacteria are isolated from a tea tree mushroom residue dump, and the resulting bacterial solution is mixed with tea tree mushroom residue and water for a first-stage fermentation at 45-60℃. Tailings-decomposing bacteria are isolated from a granite tailings dump, and the resulting bacterial solution is rejuvenated. The first-stage fermentation material is cooled to 30-45℃, and then granite tailings and the tailings-decomposing bacterial solution are added, followed by a second-stage fermentation at this temperature, ultimately yielding the bio-fertilizer. This invention addresses the differences in temperature tolerance among different bacterial strains by developing a specialized segmented inoculation process. The resulting bio-fertilizer possesses multiple benefits, including improving soil physicochemical properties, supplementing soil micronutrients, and enhancing crop resistance. It solves the problem of synergistic resource utilization of tea tree mushroom residue and granite tailings, forming a closed-loop circular economy of agricultural waste – mining waste – bio-fertilizer – green agriculture.
