The invention belongs to the technical field of soil conservation, and particularly relates to a method for promoting plant growth and regulating soil nutrients. The invention discloses a method for regulating and controlling corn and tobacco growth and rhizosphere soil nutrients through combination of AMF and a planting mode. The method comprises the following steps: preparing an AMF-containing microbial inoculum by using M. mosseae (F. mosseae); cultivating flue-cured tobacco seedlings and corn seedlings; flue-cured tobacco seedlings and corn seedlings are jointly planted in an intercropping mode by utilizing an AMF-containing fungicide. The method can relieve continuous cropping obstacles of flue-cured tobaccos and promote growth of the flue-cured tobaccos and corn, and has a certain effect on soil conservation.

This invention relates to the field of agricultural machinery technology, specifically to a straw deep-burying tillage implement and its operating method. The straw deep-burying tillage implement includes a rotating traction frame, a plow frame assembly, a deep plow body assembly, a shallow plow body assembly, a ground wheel assembly, a front cutter, a rear cutter, a tilting cylinder, and outriggers. The plow frame assembly is hinged to the rotating traction frame. The deep plow body assembly, shallow plow body assembly, and ground wheel assembly are all mounted and fixed on the plow frame assembly. The deep plow body assembly and the shallow plow body assembly are arranged in a staggered front-to-back and vertically offset manner, wherein the vertical offset is formed by the difference in the size of the two plow bodies, with the front being larger than the rear. The front-to-back offset is also arranged in a top-down direction to adapt to trenching and burying operations. The deep plow body assembly is used to dig deep trenches, and the shallow plow body assembly is used to turn over surface straw, stubble, and shallow soil into the deep trenches, achieving soil layer conversion and deep burying of straw throughout the entire plot.

The invention discloses a fertilizer for overcoming continuous cropping obstacles of pinellia ternata, which is prepared by mixing traditional Chinese medicine residues and animal waste and composting, so that on one hand, the anti-pathogen characteristic of clearing heat and drying dampness or clearing heat and removing toxicity and the medicinal components for sterilization are fully exerted; on the other hand, the organic matter content of the fertilizer is enriched, the PH value and structure of soil are improved, the porosity and matrix volume weight of the soil are increased, a microenvironment is provided for inhibiting pathogenic bacteria in the soil through a microbial agent, and the problems of soil degradation, disease accumulation and the like which are prone to occurring in continuous cropping planting of pinellia ternate are solved through cooperation of multiple aspects; by improving the soil environment, enhancing the biological control ability and providing comprehensive and balanced nutrition, continuous cropping obstacles are effectively relieved, and a powerful guarantee is provided for continuous high yield of pinellia ternate.

The invention discloses a three-dimensional composite interplanting method for interplanting poria cocos and peanuts. The three-dimensional composite interplanting method comprises the following steps: S1, soil preparation; s2, applying a composite soil conditioner and building furrows; s3, putting the poria cocos into a cellar; s4, peanut sowing; s5, field management in the symbiotic period; s6, harvesting in a staggered manner. According to the method, the poria cocos is planted underground, the peanuts are planted on the ground, after the peanuts are harvested, the ground surface is covered with peanut straw, the poria cocos is shaded, the physical properties of soil are improved by returning the peanut straw to the field, two kinds of medicines and grains are planted in one field through poria cocos and peanut interplanting, and the land utilization rate is increased; meanwhile, the composite soil conditioner prepared by a specific method is applied, long-acting and synergistic biological stimulation is provided for the two crops, the soil permeability is improved, and special pretreatment is performed on pine sections, so that the poria cocos inoculation rate, stress resistance and yield of poria cocos strains are remarkably improved, the soil micro-ecological environment is improved, the soil permeability and enzyme activity are improved, and the yield of the poria cocos strains is increased. And double improvement of economic benefits and ecological benefits is realized.

The invention provides electron-rich biochar as well as a preparation method and application thereof, and belongs to the technical field of solid waste biomass utilization. The preparation method of the electron-rich biochar provided by the invention comprises the following steps: performing pyrolysis carbonization on a biomass raw material under an anaerobic condition to obtain a biochar precursor; mixing the biochar precursor, a reducing agent and water, and reducing to obtain the electron-rich biochar, the reducing agent is prepared from one or more of KHB4, NaBH4, LiBH4 and LiAlH4. The reducing agent can reduce the abundance of functional groups-NH2 / -OH on the surface of the biochar, and also can introduce electron-rich (orbital) high-energy alkyne bonds, so that the specific capacitance value of the biochar is increased, and an electron-rich soil capacitor is obtained; the reducing agent reduces a diffusion impedance layer on the surface of the biochar and charge transfer resistance in the biochar, the biochar rich in pi-electronic chemical structures is prepared, saponin substances are eliminated, and continuous cropping obstacles are effectively relieved.

The application provides application of taurine in promoting growth of Panax notoginseng, inhibiting bacteria, inducing Panax notoginseng to produce resistance and / or relieving Panax notoginseng continuous cropping obstacles, and further provides a method for promoting growth of Panax notoginseng, inhibiting bacteria, inducing Panax notoginseng to produce resistance and / or relieving Panax notoginseng continuous cropping obstacles, and a biological pesticide, a Panax notoginseng resistance inducer, a Panax notoginseng growth regulator and a Panax notoginseng continuous cropping obstacle reliever. Research shows that within a certain concentration range, taurine can significantly promote the growth of Panax notoginseng, inhibit the growth of the root rot pathogen of Panax notoginseng, reduce the occurrence of root rot, significantly relieve the continuous cropping obstacles of Panax notoginseng and enhance the resistance of Panax notoginseng to Alternaria alternata, and significantly reduce the disease area of Alternaria alternata. Moreover, taurine has the advantages of low toxicity, no pollution, environmental friendliness and the like, and is an effective way for green ecological prevention and control of Panax notoginseng.

This invention discloses a compound microbial agent containing Pseudomonas and its application, belonging to the field of agricultural microbiology technology. The compound microbial agent of this invention includes a Pseudomonas synthetic flora and N-acetyl-L-tryptophan. N-acetyl-L-tryptophan can effectively inhibit the growth of pathogens and effectively improve the colonization ability of Pseudomonas in the soil.
