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 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 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. The combined use of Pseudomonas and N-acetyl-L-tryptophan can increase the relative abundance of beneficial bacteria and decrease the relative abundance of harmful bacteria in continuously cropped soils; increase the positive correlation ratio of microbial interactions in continuously cropped soils; reshape the rhizosphere microenvironment of apples; and promote the growth of apple seedlings in continuously cropped soils, thereby significantly improving the control effect on continuous cropping obstacles in apples.
