福建沿海丘陵山地果园节水技术的发展现状与展望

简要介绍福建沿海丘陵山地果园节水技术的发展历史,并从渠道防渗、低压管道输水灌溉、喷灌、微灌、渗灌等节水工程技术以及覆盖保墒、选用抗旱品种、化学调控等节水农业技术方面论述福建沿海丘陵山地果园节水技术的现状,指出当前果园节水技术虽然发展较快,但存在着设施不完善、管理水平低、投资水平低等不足,提出水利措施与农艺措施的优化组合,将节水工程技术、节水农业技术因地制宜进行有机结合,加强果树需水规律和灌溉制度的研究,把有限的水量集中用于作物需水关键期,形成高效节水的新型果园综合技术节水技术体系。

Actuality and Expectation in Saving Water Technique in Fujian Mountainous Loquat Orchard

This paper introduced the development history of water-saving technique in Fujian mountainous orchard, and discussed the current situation of the water-saving technology in the mountainous orchard from canal seepage control technology, low press conduit pipe, drip irrigation,micro-irrigation, subsurface drip irrigation,cover moisture preserving, drought resistant varieties and chemical control?The paper point out the water-saving technology in the orchard develops very fast, but there are a lot of unfavorable factors such as irrigation projects are not perfected, management and investment level were low. In this paper,the authors propose optimization for combination of water conservancy measure and agronomy measure, combination of water-saving Engineering and agricultural technique and research of orchard water demand rule and irrigating system were necessary to the development of high-efficient water-saving technology system.
