Research on the Water-Upland Rotation Model of"Facility Melon-Rice"
A comparative study was conducted on"facility melon-rice"water-drought rotation model and the"facility melon-idle"model in the main melon production areas in Taizhou City,Zhejiang Province.The results indicated that the"facility melon-rice"water-drought rotation model is suitable for selecting melon grafting seedlings and rice varieties with a whole growth period of about 140 days.Water-drought rotation could improve soil properties,reduce the mortality rate of grafted melon seedlings in field,improve melon quality and land utilization,solve the conflict between grain and economic crops for land use,and increase the benefits by 639.9 yuan/667 m2.It is a sustainable and efficient cultivation model.
