Embodiment 1

[0033] A kind of preparation method of the soil restoration organic fertilizer that overcomes watermelon cropping obstacle, comprises the following steps:

[0034] Crush the crop straw to 3-5cm, add 5Kg of straw decomposing agent per ton of straw, mix the straw and straw decomposing agent, build a pile for fermentation, and turn the pile once a day after the fermentation temperature reaches 60-70°C on the third day. Keep it at 50%-80%, and the pH value is 6.5-7.5; then add N, P, and K fertilizers. The amount of N, P, and K fertilizers added is: N fertilizer: 5kg per ton of straw, P fertilizer: per ton of straw Add 1.5kg, K fertilizer: add 0.5kg per ton of straw; continue to ferment, after the tenth day, the temperature is 30-40°C, the water content is 30% to 50%, turn the pile once every two days; after the fifteenth day of fermentation , the temperature is the same as room temperature, and the water content is 15% to 25%, to prepare an organic fertilizer for soil restoration....

Embodiment 2

[0045] A kind of preparation method of the soil restoration organic fertilizer that overcomes watermelon cropping obstacle, comprises the following steps:

[0046] Crush the crop straw to 3-5cm, add 3Kg of straw decomposing agent per ton of straw, mix the straw and straw decomposing agent, build a pile for fermentation, and turn the pile once a day after the fermentation temperature reaches 60-70°C on the third day. Keep it at 50%-80%, and the pH value is 6.5-7.5; then add N, P, and K fertilizers. The amount of N, P, and K fertilizers added is: N fertilizer: 3kg per ton of straw, P fertilizer: per ton of straw Add 0.7kg, K fertilizer: every ton of stalks adds 1kg; Continue to ferment, after the tenth day, the temperature is 30-40°C, the water content is 30%~50%, turning once every two days; after the fifteenth day of fermentation, The temperature is the same as the room temperature, and the water content is 15% to 25%, and the organic fertilizer for soil restoration is prepare...

Embodiment 3

[0056] A kind of preparation method of the soil restoration organic fertilizer that overcomes watermelon cropping obstacle, comprises the following steps:

[0057] Crush the crop straw to 3-5cm, add 4Kg of straw decomposing agent per ton of straw, mix the straw and straw decomposing agent, build a pile for fermentation, and turn the pile once a day after the fermentation temperature reaches 60-70°C on the third day. Keep it at 50%-80%, and the pH value is 6.5-7.5; then add N, P, and K fertilizers. The amount of N, P, and K fertilizers added is: N fertilizer: 2kg per ton of straw, P fertilizer: per ton of straw Add 1kg, K fertilizer: every ton of stalks adds 0.6kg; Continue fermentation, after the tenth day, the temperature is 30-40°C, the water content is 30%~50%, turn over once every two days; after the fifteenth day of fermentation, The temperature is the same as the room temperature, and the water content is 15% to 25%, and the organic fertilizer for soil restoration is pre...

Abstract

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.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and in particular relates to a soil repair organic fertilizer for overcoming the obstacle of repeated cropping of watermelons, a preparation method and an application thereof. Background technique [0002] At present, large-scale, industrialized, and specialized planting of high value-added crops have been formed in many areas of our country, and many areas and farmers have already established their own brands, reputation, and customer groups. However, due to the obstacle of continuous cropping, the land resources in the production area are scarce. Many farmers have to rotate crops or plant in different places, seriously affecting market efficiency and sustainable development. [0003] The continuous cropping obstacle refers to the phenomenon that when the same crop or related crops are planted continuously in the same soil, even under normal cultivation and management conditions, the pla...
