Site preparation Correct soil preparation is the most important factor affecting the fumigation effect of the soil. Bad preparation will affect soil disinfection. Ensure that there are no crop stalks, no large clumps, and especially to remove stubborn roots from the soil. Because most fumigants do not penetrate the roots of crops, they kill the pathogens in the roots. This will lead to poor disinfection and become a new source of infection. Soil looseness is more than 35 cm. Maintaining the permeability of the soil will help the movement of the fumigant in the soil to achieve a uniform disinfection effect. Soil temperature The soil temperature has a great influence on the movement of the fumigant in the soil and also affects the living "organisms" in the soil. Proper soil temperature helps the fumigant move. If it is too cold, the fumigant moves slowly; if it is too hot, the fumigant moves faster. The ideal temperature is to keep the target organisms "live" for better killing. The ideal soil temperature is usually 15cm at 15-20°C. Soil moisture Appropriate soil moisture ensures that the testicles of the weeds are softened, the pests are in a "growth" state, and there is sufficient humidity to "activate" the fumigant, such as Viagra and Cottonlon. In addition, humidity helps the fumigant to move through the soil. The general soil moisture should be about 60%. plastic film Since the fumigant greatly differs in the penetrability of different plastic sheets, the quality of the film significantly affects the fumigation effect. It is recommended to use the original film of 0.04mm or more, and it is not recommended to use the regeneration film. If the plastic sheet breaks, it needs to be repaired with a wide plastic tape. The most effective plastic film at the moment is a non-permeable membrane, which can greatly reduce the emission and dosage of fumigant.
