How to raise leeks after cutting?
2. Water and fertilize. You can't water and fertilize leek immediately after cutting, because water and fertilizer are easily polluted in leek stubble, and it is easy to get infected with germs at this time. Therefore, after cutting leeks, it is best to wait for a week or so before watering and fertilizing. Urea or ammonium sulfate 15 ~ 20k g/ mu can be used to promote the growth of Chinese chives and make their leaves fatter. You need to control the amount of water when watering, as long as you keep the soil moist.
3. Pest control. The main pest of leek is leek maggot, which seriously harms the normal growth of leek, and corresponding control measures should be taken in time according to the actual situation. In the case of leek maggots, we can choose the method of chemical root irrigation, and dilute 500 ml of emamectin EC with 2% concentration per mu into 1000 times solution for root irrigation. Adult leek maggots should be sprayed with 2.5% deltamethrin EC for 2000 times per mu at 9- 10 on sunny days.
