First, spray or watering method.
The medicament is diluted with water to 200 to 300 times, sprayed evenly on the surface of the soil with a sprayer or directly into the soil, so that the liquid penetrates into the deep layer of the soil and kills the bacteria in the soil.
Second, the poisonous soil law. First, the agent is formulated into a poison and then applied. The method for preparing the toxic soil is to mix the pesticide (emulsifier, wettable powder) with fine soil with a certain humidity at a ratio of 1:50 to 1:80. The commonly used medicaments are the same as the spray method, and the poisonous soil application method has application, ditch application and acupoint application.
Third, solar disinfection. The use of solar energy disinfection is explored in practice. The method is to remove the old plants after rooting in the greenhouse or the field crops, apply the organic fertilizer to the farmhouse, and then level the soil well. When the temperature is above 35 degrees from July to August, cover it with a transparent heat-absorbing film. The medium temperature can be raised to 50 degrees to 60 degrees, and sealed for 15 days to reach 20 days, which can kill various bacteria in the soil. This method is extremely practical and can be actively adopted.

The East-West glass slide is a glass slide or quartz slide that is used to place a glass slide or quartz slide when it is observed under a microscope. During production, a cell or a sample containing a certain tissue is randomly placed on the slide glass, and a cover slip is placed on it for observation a similar material that produces a phase difference.
