Soil remediation organic fertilizer for overcoming watermelon replantation obstacle, preparation method thereof and application thereof
InactiveCN106380269AOvercoming stubble obstaclesOvercoming obstacles to continuous croppingFungiBacteriaFiberPlant roots
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.
