“设施甜瓜-水稻”水旱轮作高效栽培模式研究

Research on the Water-Upland Rotation Model of“Facility Melon-Rice”

在设施甜瓜主产区因地制宜开展了“设施甜瓜-水稻”水旱轮作高效栽培模式和“设施甜瓜-空闲”模式比较研究。结果表明,“设施甜瓜-水稻”水旱轮作模式适宜选用甜瓜嫁接苗和全生育期140 d左右的水稻品种;水旱轮作能改良土壤性质,减少大田种植甜瓜嫁接苗死株率,提高甜瓜品质和土地使用率,解决粮经争地矛盾,并净增收益639.9元/667 m2。该模式是一种可持续发展的高效栽培模式。

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 m 2.It is a sustainable and efficient cultivation model.
