How to manage garlic under plastic mulch after it turns green again? Remember these key points
1. Topdressing and watering. From late February to early March, temperatures rise and garlic under plastic mulch begins to turn green again. Because plastic mulch has a heat-preserving and moisture-retaining effect on the soil, generally, when garlic under plastic mulch has been watered thoroughly before winter for overwintering, it should not be watered early in spring, to prevent the soil temperature from dropping. If there is a spring drought and the soil lacks water, water once in early to mid-March. Remove the mulch in April, weed, loosen the soil, apply topdressing, and water. Apply 15-20 kg of urea or 30-40 kg of ammonium bicarbonate and 10-15 kg of potassium sulfate per mu. After fertilizing, irrigate once thoroughly. Appropriately control watering in the later stage. Keep the field
