The sheds in greenhouses are mainly pollution-free methods that use solar heat to sterilize the soil. First of all, before the high-temperature stuffy shed, we must first apply the right amount of organic fertilizer, and throw in lime nitrogen (calcium cyanide) 60-80 kg. Provides plants with nitrogen nutrition and reduces the nitrate content of agricultural products. Then plunge the soil deeper, flatten the ridge and fill it with water until it is saturated. Finally, the whole greenhouse floor is covered with plastic film, and the air vents are closed and the sheds are sealed. In case of fine weather, the occupants are kept in a row for 10-15 days. After a high-temperature greenhouse, it can significantly reduce the soil-borne diseases caused by heavy smashing, kill root-knot nematodes, and degrade the toxic and harmful components in organic fertilizers. Through high-temperature stuffy sheds, we can effectively prevent diseases such as blight, oomycete, root-knot nematode, and fungi. The stuffy shed is best combined with dry boring and stuffy stuffy. That is, dry watering after 5-7 days. After watering for 3-5 days, boring for another 5-7 days, to solve the dry bacteria, bacilli, spores, decidua and other bacteria to dry heat. Stop for a few days after watering to make it reactivate or grow. Then it will be easy to kill them.
