Peanut fertilizer for preventing bacterial wilt and preparation method of peanut fertilizer

Abstract

The invention belongs to the technical field of chemical preparation, and discloses peanut fertilizer for preventing bacterial wilt and a preparation method of the peanut fertilizer. The preparation method comprises the steps: an organic fertilizer-inorganic fertilizer mixed fertilizer culture medium special for peanuts is prepared; a test culture medium is prepared; antagonistic bacteria are screened; and the fertilizer containing the antagonistic bacteria is prepared. Long-acting organic-inorganic compound fertilizer is adopted as the culture medium to screen the antagonistic bacteria whichcan fully utilize the organic fertilizer special for the peanuts to generate antagonistic substances, and peanut bacterial wilt can be effectively prevented; meanwhile, the characteristics of the organic fertilizer, inorganic fertilizer and long-acting fertilizer special for the peanuts are synthesized, organic matter and inorganic nutrients are rich, the nutrients are complete and sufficient, andthe peanut fertilizer serves as base fertilizer to be applied at a time; and on the basis of guaranteeing the corn and peanuts, the fertilizer application amount is decreased, the requirements for farmers are low, labor input is lowered, resources are saved, the environment is protected, the soil microbial balance is effectively improved, a damaged soil ecosystem is restored, and thus a complex and healthy soil microbial system is established.

Description

technical field [0001] The invention belongs to the technical field of chemical preparation, and in particular relates to a peanut fertilizer for preventing bacterial wilt and a preparation method thereof. Background technique [0002] Ralstonia solanacearum mainly overwinters in the soil, diseased residues and incompletely decomposed compost, and becomes the main source of initial infection in the next year. In the field, it is mainly spread by soil, running water, agricultural tools, humans, animals and insects. After sowing peanuts, the daily average temperature is above 20°C, and the soil temperature at the depth of 5cm is stable above 25°C for about 6-8 days before the disease begins. The ten-day average temperature is higher than 25°C, and the ten-day average soil temperature is 30°C. Observation in Zhanjiang: The temperature is 27-31°C, the rainfall in spring peanuts is 120-150mm from April to May, and the rainfall in autumn peanuts is 150-200mm in September. The dis...

Problems solved by technology

[0004] In the prior art, no long-acting organic-inorganic compound fertilizer is used as the culture medium to screen antagonistic bacteria that can make full use of peanut-specific organic fertilizers to produce antagonistic substances, which cannot effectively prevent the occurrence of peanut bacterial wilt; meanwhile, there is no comprehensive peanut-specific organic fertilizer. The characteristics of fertilizers, inorganic fertilizers and long-acting fertilizers cannot reduce the amount of chemical fertilizers on the basis of ensuring peanuts, resulting in high costs, failing to save resources and protect the environment, and failing to effectively improve the balance of soil microorganisms and restore the destroyed soil ecosystem.

[0005] The cost of chemical agents to control R. solanacearum is high, the effect is poor, and the soil pollution is serious. Crop rotation control cannot meet the actual needs of production in the south. The traditional drying room can only dry the materials through fans, and cannot control the drying time and temperature of the materials. slow drying

[0006] The traditional belt conveyor can only be started and stopped by the motor control device, it is difficult to control the synchronization of the transmission, it is easy to cause the material to be spilled during the transmission, and the transmission is uneven, which is difficult to meet the application in fertilizer production
