At the moment, when greenhouses are exposed to high temperatures and are sterilized and sterilized, many farmers have doubts. When should organic fertilizers be used? After the boring shed or after the boring shed? If there is any loss of nutrients if it is applied before disinfection of the soil in the greenhouse? The correct answer is: Organic fertilizers should usually be applied before the soil is sterilized. The reasons for the analysis are as follows: First, organic fertilizers that have not been fully decomposed will be further decomposed after being treated with stuffy sheds. Second, pathogenic bacteria, harmful insects and other harmful microorganisms in organic fertilizers will be basically destroyed after being treated in a high-temperature boring treatment. Crops produce hazards; Third, microbial fertilizers and bio-organic fertilizers that exceed the expiration date should also be applied before disinfection in soil dwellings to prevent contamination of the soil by disinfectants. It cannot be denied that the application of organic fertilizer before soil disinfection has a loss of nutrients, especially nitrogen in fertilizers, the loss will be greater, and it will have little effect on phosphorus and potassium. In the choice between the loss of organic fertilizer nutrients through disinfection and the possible killing of organic fertilizer, it is better to lose some nutrients and not to disinfect and then apply the organic fertilizer with pathogens. It needs to be added that in the high-temperature retort sterilization, beneficial bacteria and harmful bacteria on the surface of the soil are actually killed. Therefore, the fungicide should be used after the dungeon. Otherwise, the biological bacteria in the surface soil are in the “empty periodâ€, and harmful bacteria in the deep soil will still come up. After high-temperature stuffy shed, proper application of bacterial fertilizer can effectively inhibit the occurrence of root diseases.
