高寒半干旱区大白萝卜地膜覆盖栽培技术的研究

Study on Plastic Sheet-Covered Cultivation Technology of Large White Radish in the Cold and Semiarid Region

通过1997-1998年在张北试区下湿滩地进行大白萝卜地膜覆盖栽培研究表明,在坝上高寒半干旱区土壤肥力和地下水位较高的下湿滩地,利用地膜覆盖的增温、保水和除草效应,进行大白萝卜地膜旱作栽培,可以达到省工、省肥、节水、增产、增收的效果,为坝上地区蔬菜生产提供了一项具有区域特色的蔬菜旱作节水栽培新技术。

The sesults of experiments from 1997 to 1998 indicated that plastic sheet-cov-ered cultivation technology was suitable for cultivating Large White Radish in wet shoalyland of the cold and semiarid region in Bashang Plateau. Using this technology can increasesoil temperature and moscture, reduce work of weeding and consumption of water, increaseoutput and income of Large White Radish.
