Question 1: What factors affect the fumigation effect?
Correct soil preparation is the most important factor affecting the fumigation effect of 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 Soil temperature has a great influence on the movement of fumigants in the soil and also affects 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 Humidity The proper soil moisture ensures that the seed coat of the weeds is softened, the pests are in a "growth" state, and there is sufficient humidity to "activate" the fumigant, such as Vega and cotton. In addition, humidity helps the fumigant to move through the soil. The general soil moisture should be about 60%.
Since the plastic film has a great difference in the penetrability of different plastic sheets by the fumigant, 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.
Question 2: After soil disinfection, pay attention to what?
After the fumigation, the growing time should be increased when it is cold and wet; the open time can be reduced when it is hot and dry; the open time should be increased when the organic matter is high; the clay needs longer gas than the sand. time.
After the pastoral hygiene and management of soil extermination, it is crucial to avoid the reintroduction of pests and diseases. Inadvertent soils, plant wastes formed from previous crops, and insect pests in irrigation water may inadvertently be brought into the treated soil. Should avoid the unsterilized soil on the plastic cloth into the disinfection of the field, to avoid disinfection and then turn cultivation.
Seed treatment In order to avoid the introduction of soil-borne diseases into the treated soil, we should start with the seeds. First of all, we should select the best disease-resistant varieties cultivated in the area according to the development situation of the local vegetable pests and diseases. Seed disinfection before sowing, such as soaking in hot soup, high-temperature dry heat disinfection, seed dressing, liquid soaking and other methods, can reduce or resist the occurrence of diseases.

The fruit, corn, contains a lot of magnesium, which is known to be one of the few trace elements in the food and can help prevent cancer development.And the fruit corn contains a substance called glutathione, which can make some chemical carcinogens in the body toxic.To ward off cancer.
Although corn is highly nutritious, it is rich in crude fibre, so for children with delicate stomachs, too much of it can easily cause indigestion. If you add milk to the juice and then give it to your child, it will be less taxing on the stomach and more nutritious, and your child will be able to eat more food. (This method uses a wall breaker, but if you don't have one, a juicer is fine.)
