The invention relates to a conditioner for slowing down continuous cropping obstacles of ginger and an application method thereof. Raw materials of the conditioner comprise, by weight, 3-8% of phenylalanine, 0.5-1.5% of ferulic acid ester, 0.5-1.5% of caffeic acid, 0.5-1.5% of isoeugenol, 0.5-3% of salicylic acid, 0.5-3% of chitosan, 1-3% of borax, 2-5% of zinc sulfate, 2-5% of magnesium sulfate, 3-10% of ethanol, 1-4% of acetic anhydride and 60-85% of water. The conditioner has a simple preparation technology, is low-cost, is used to raise autotoxicity resistance of ginger plants and has good effects of conditioning growth, enhancing stress resistance and slowing down continuous cropping obstacles of ginger. In comparison with yield of a control group without the application of the conditioner, yield of a group with the application of the conditioner is increased by 10-20%.

The invention relates to a method for relieving pseudo-ginseng autotoxicity injuries by adding exogenous gentiobiose, belonging to the technical field of plant protection. The technical scheme is as follows: carrying out seed soaking treatment on pseudo-ginseng seeds by using a 1.0-50.0 mg / L gentiobiose solution; or dissolving gentiobiose in seed coating Celest to prepare a 5.0-500.0 mg / L gentiobiose seed coating, and carrying out coating treatment on the pseudo-ginseng seeds according to the agent:seed mass ratio of 1:50; or carrying out root soaking treatment on seeds and seedlings by using a 1.0-50.0 mg / L gentiobiose solution. The exogenous antioxidant is added to enhance the resistance of pseudo-ginseng, lower the cell injuries caused by autotoxic substances in the pseudo-ginseng growth process so as to increase the root rot damage probability, and reduce the consumption of pesticides; and thus, the method is an ecological safe effective measure for relieving successive cropping obstacles.

The invention relates to a method for repairing continuous cropping obstacles of peanuts based on an allelopathic autotoxicity effect. The preparation method comprises the following steps: (1) seed dressing treatment is carried out by adopting a compound microbial agent in a peanut seeding period; the compound microbial agent comprises streptomyces tenebrarius and a synergist, wherein the synergist is a mixed solution of difenoconazole and a thiram solution diluted by 1000-2000 times, and the ratio of the difenoconazole to the thiram solution is 1:5-5:1; and the using method is seed dressing;and (2) a compound bacterial fertilizer is applied to holes in a peanut seedling period, and puddling is carried out; the bacterial fertilizer comprises 30-70 parts of sheep manure and 30-70 parts ofwormcast, and the usage amount of a microbial inoculum is 0.05-0.1%; and the microbial inoculum consists of 40-60 parts of streptomyces tenebrarius and 40-60 parts of yeast, and hole application treatment is carried out during seeding, 20-30 g of the compound bacterial fertilizer is applied to each hole, and the compound bacterial fertilizer is stirred and mixed with soil in the holes. The methodhas the beneficial effects that the emergence rate and the survival rate of peanuts are greatly improved. The sheep manure, the wormcast and the streptomyces tenebrarius are adopted for fermentation,so that the efficacy of the wormcast is supplemented by the sheep manure. The streptomyces tenebrarius is bred in the bacterial fertilizer, so that the production of a peanut root system is facilitated, and the influence on continuous cropping obstacles is eliminated.
