The soil must remain moist when transplanted. Can be used single membrane or film and small arch membrane "double membrane" covering cultivation, large and medium potato rate can be increased by 10% -30%, there is a significant increase in production effect, and can mention the city for 10-20 days. Generally not watered before emergence. After the soil is formed after the rain, the earth should be ventilated in time. Qimiao chase after the application of tree fertilizer, mu urea 5 kilograms of water pouring or use of decomposing human fecal urine pouring.
