摘要：

在温光资源适宜地区,因地制宜开展“早晚稻+西兰花”水旱轮作栽培技术研究,旨在探究在保证粮食生产条件下提高稻田周年生产效益的途径。试验对比了“双季稻+冬闲”“双季稻+西兰花”两种模式水稻产量、水稻季氮肥偏生产力以及稻田周年生产效益。结果表明,“双季稻+西兰花”模式可以显著提高连作早稻产量、早稻季氮肥偏生产力,降低早稻季肥料投入成本,大幅度提高稻田周年生产效益。“双季稻+西兰花”水旱轮作是实现双季稻绿色节本增效可持续发展的栽培技术。

Abstract:

In the areas with suitable temperature and light resources, it is of significance to study the effects of paddy-upland rotation on annual production efficiency in paddy field. Two rotation systems, “early-late rice + winter fallow” and “early-late rice + broccoli”, were set. The results showed that the“early-late rice+broccoli” rotation system significantly increased yield and N partial factor productivity in early rice and annual income in paddy field. The “early-late rice +broccoli” rotation system in suitable areas was a green and low input and high efficiency cultivation system.

Key words: paddy-upland rotation, early rice, later rice, broccoli, yield, income
