改进地面灌水技术设施的研究

地面灌溉是一种古老而又应用最广的灌水方法,世界上各国都十分重视改进地面灌水技术的研究。本文提出了二种新的改进地面灌水技术设施——麦棉套膜上灌和简易间歇灌研究结果,它们均具有节水增产、灌水速度快、灌水均匀和投资小的优点,并对此二种地面灌水方法的设施、控制运用和节水增产机理作了初步探讨。

A Study on Technique of Improving Surface Irrigation

Mankind has been spreading water on the land by surface irrigation for many thousands of years, and in every country where irrigation is practised, local methods have developed. The scientific approach of recent years has selected and developed those which are effective.Two techniques of improving surface irrigation-furrow irrigation though plastic filmmade on wheat-cotton interplanting field and simple surge flow irrigation including their performance, controlling operation and water-saving high-yield function are presented hereafter.The advantages of them are water-saving high-yield less-investment, to make the high flow velocity and high irrigation quality.
