The application of ammonium bicarbonate or immature organic fertilizer will release a large number of harmful gases. If it is not ventilated in time, it is easy to appear the phenomenon of "dry tip" of leek. ⑵ high temperature hazard. The protected leek grows in the high temperature environment of more than 30 ℃ for a long time, and without timely cooling control, coupled with dry air, it is easy to cause the dry tip of the leek to wither and turn yellow. Too much fertilizer was applied to ⑶ and the soil was acidified. If a large number of acid fertilizers are applied, the soil will be too acidic, resulting in the dry tip of leeks. ⑷ is not ventilated properly.

The prevention and control of dry tip of leek can refer to the following methods: ⑴ should apply less ammonia fertilizer as much as possible, organic fertilizer should be fully ripened and then applied, if applied, it should be ventilated in time to discharge harmful gases to prevent air damage. ⑵ avoids excessive application of acid fertilizer to prevent soil acidification; for soils with excessive acidity, lime can be used to adjust. ⑶ cooled and watered in time, and added nitrogen fertilizer to enhance the heat resistance of Chinese chives. ⑷ should control the dosage and use as few manganese-containing pesticides as possible.
