Immersion seed germination of pumpkin seeds by the sun for 2 days, immediately stir in 50 °C hot water, water temperature dropped to about 30 °C when the seeds soaked for 15 to 20 minutes after the natural cooling, continue to soak seeds for 7 to 12 hours. After soaking, the germination is maintained at a germination temperature of about 30°C, and germination occurs within two days.
Finely site-selected pumpkin seedlings with good drainage, paddy fields and vegetable lands where the groundwater level is at the bottom and the soil is fertile. Width 1.5 meters wide, open good sulcus, groove width 30 cm, 15 to 20 cm deep groove, open the drainage ditch on all sides.
