浙江南部山区高效节水灌溉模式探究

Efficient Water-saving Irrigation Mode in Mountainous Areas of Southern Zhejiang

浙江南部山区灌溉存在因地形落差大,田块蓄水能力较差;山间水源分散,灌溉困难;所种植的作物结构变化大,不易形成成片灌溉;灌溉设施落后,较难扩大种植规模等问题。为此以浙南山区缙云县五个村高效节水灌溉项目为例,提出在山区建设堰坝截蓄水流,分区分块种植,利用管道与微灌的方式节水灌溉等措施,以提高水利用率。

In the southern mountainous areas of Zhejiang Province,there are some problems like poor water storage capacity due to topographic drop,inadequate irrigation in mountainous areas because of dispersed water sources and great changes of crop structure,and limited planting scale due to backward irrigation facilities.Based on high-efficiency water-saving irrigation projects in 5 villages of Jinyun County,some measures are put forward in this paper,such as constructing weir dam in mountainous area to keep water storage,planting in sub-areas and water-saving irrigation by means of pipelines and micro-irrigation,to improve the efficiency of water resources.
