Embodiment 1

[0032] A kind of preparation method of soil remediation organic fertilizer that overcomes the obstacle of repeated cropping of Panax notoginseng comprises the following steps:

[0033] 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. 1.5kg, K fertilizer: add 0.5kg per ton of straw; continue fermentation, after the tenth day, the temperature is 30-40°C, the water content is 30%-50%, and the pile is turned 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 prepared.

[0034] The preparation method of described straw decomposing agent is:

Abstract

The invention provides a soil remediation organic fertilizer for overcoming panax notoginseng continuous cropping obstruction, a preparation method and application of the soil remediation organic fertilizer. The soil remediation organic fertilizer is prepared by conducting mixed fermentation on crop straw, a straw decomposition agent and N, P and K fertilizer. The straw decomposition agent is obtained by conducting crossing antagonistic culture on four strains, wherein bacillus subtilis is used for inhibiting and killing harmful bacteria and pathogenic bacteria in soil, trichoderma reesei is used for decomposing straw fibers and quickly decomposing the straw, lactobacillus plantarum is used for inhibiting and killing pests and pest eggs in the soil, and bacillus mucilaginosus is used for removing autotoxicity residues of panax notoginseng. The microbial agent cooperates with the crop straw and the N, P and K fertilizer to achieve the effects of overcoming continuous cropping obstruction inducements such as soil-borne pathogen accumulation, soil nutrient unbalance and plant autotoxicity, supplementing soil organic matter and optimizing the aggregate structure of the soil, therefore, water retention, water drainage and ventilation are achieved, and crops are developed in root system and healthy and strong in plant.

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 Panax notoginseng, a preparation method and an application thereof. Background technique [0002] At present, large-scale, industrialized, and specialized planting of some high value-added crops has been formed in many areas of our country, and many areas and farmers have already established their own brands, reputation, and customer base. 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,...
