滴灌成套设备和低压大流量滴头研制与应用

Developing and Applying Unit Equipment for Drip Irrigation and Emitter with Low Pressure and Large Discharge

经过10多年的科学研究,我国在微灌设备研制方面取得了一定进展,先后生产试制了微灌用聚乙烯管材与管件,研制出了一批灌水器和过滤、施肥装置,促进了微灌技术的推广运用。对微管灌水器进行的系列化研究,降低了工程造价,提高了灌水质量。

Some progresses have been made in developing micro-irrigation equipment in China after having researched for 10 years. Some PVC pipes and couplings have been made. A lots of emitter, filters and fertilizer injection equipment have been developed. All this has promoted the applying and spreading of micro-irrigation techniques, the research in the seriazation of micro-tube emitter has brought about the reduction of the price of engineering and raise the water quality.
