The present invention provides a soil remediation organic fertilizer for overcoming a watermelon replantation obstacle, a preparation method thereof and an application thereof. Agricultural straws, a straw-decomposing inoculant, an N fertilizer, a P fertilizer and a K fertilizer are subjected to mixed fermentation to prepare the soil remediation organic fertilizer. The straw-decomposing inoculant is prepared through subjecting four strains to cross antagonism and cultivation. The above four strains are composed of bacillus subtilis, Trichodermareesei, lactobacillus plantarum and Lactobacillus acidophilus. The bacillus subtilis is used for inhibiting and killing harmful bacteria and pathogenic bacteria in the soil. The Trichodermareesei is used for decomposing straw fibers and quickly composting straws. The lactobacillus plantarum is used for inhibiting and killing insects and worm eggs in the soil. The Lactobacillus acidophilus is used for removing the autotoxicity residues of watermelons. The effects of fungicides are realized based on the mutual coordination of the fungicides, agricultural straws, N, P and K fertilizers. Therefore, the accumulation of soil-borne pathogens, the soil nutrient imbalance and the plant autointoxication, which are inducement for replantation and successive cropping obstacles, can be avoided. Meanwhile, soil organic matters are supplemented, and the soil aggregate structure is optimized. Therefore, the soil remediation organic fertilizer has the advantages of water retention, drainage and ventilation, so that the plant root system is developed. Plants are enabled to grow healthily.

According to shade tolerance of Lanzhou lily which is a perennial plant, wide and narrow belt alternated planting is adopted for interplanting, each wide lily belt is interplanted with a row of corns or two rows of broad beans, an interplanting period is three years, lilies are interplanted with the corns in the first year, and then the broad beans take the succession of corn belts in the next year. By the corns and the broad beans for crop rotation, a space barrier can be formed to inhibit large-area spreading of lily leaf wilt and root system diseases, and the plant infection rate is decreased by more than 60% as compared with that of single planting of the lilies; disorders of root exudate autotoxicity due to perennation of the lilies are abated, a community structure of soil microorganisms is changed, and development of pathogenic microorganisms is inhibited.

The invention discloses a fertilizer special for capsicum annuum in the technical field of capsicum annuum planting. The fertilizer is prepared from, by weight, 38-46 parts of a BB fertilizer, 23-29 parts of sulfur coated urea, 35-47 parts of a potassium sulphate type compound fertilizer, 22-28 parts of humic acid, 7-10 parts of attapulgite powder and 0.2-0.5 part of EM bacteria. During preparation, the preparation method comprises the steps of firstly, grinding, wherein attapulgite is ground into the attapulgite powder with the specific surface area higher than 460 m<2> / kg; secondly, mixing,wherein the BB fertilizer, the sulfur coated urea, the potassium sulphate type compound fertilizer, the humic acid, the attapulgite powder and the EM bacteria are evenly mixed to prepare the fertilizer special for the capsicum annuum. In the scheme, the fertilizer special for the capsicum annuum achieves balanced supply of nutrients to capsicum annuum planting land through the interaction of the raw materials, the situation that a beneficial bacterium community is dominant is formed, and the autotoxicity, caused by allelochemicals, of the capsicum annuum is greatly reduced; therefore, the successive cropping obstacle of the capsicum annuum is greatly reduced.

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.
