华北地区设施蔬菜节水技术集成模式综合评价

Comprehensive Evaluation of Vegetable Water-saving Technology Integration Mode in North China

为了找到适宜华北区广泛推广的蔬菜节水集成技术,笔者运用熵权综合评价法,对华北地区"蔬菜减蒸降耗及种植管理农艺和生物节水技术集成与示范"课题形成的蔬菜农艺节水技术为主的集成模式进行生产、社会经济、生态环境等方面综合评价。评价结果表明,黄瓜膜下沟灌最优、黄瓜膜下滴灌次优、黄瓜不覆盖沟灌最差,番茄膜下滴灌最优、番茄膜下沟灌次优、番茄不覆盖沟灌最差。膜下沟灌和膜下滴灌适宜在华北区种植设施蔬菜时广泛推广。

In order to find the suitable promotion vegetable water-saving integrated technology in northern region, the author applied comprehensive evaluated vegetables agronomic water-saving technology integration mode by entropy method. The results showed that the cucumber membrane under furrow irrigation was the best, the cucumber drip irrigation was sub-optimal, cucumber no cover furrow irrigation was the worst, the tomato drip irrigation was the best, the tomato membrane under furrow irrigation was suboptimal, tomato no cover furrow irrigation was the worst. Membrane under furrow irrigation and drip irrigation was suitable to widely promote planting vegetable in northern region.
