摘　　要：采用黄瓜干湿交替灌溉方式,研究了不同的灌溉频率对日光温室黄瓜生长发育、产量和干物质积累的影响。结果表明,高频率灌水显著增加了株高,增加了黄瓜单株果实重量,平均单瓜重以及产量,但减少了的茎粗,干物质积累和水分利用率。适宜的灌溉频率也即是在滴灌条件下灌溉频率为6天对于增加叶片的叶绿素含量、干物质积累和水分利用率是有利的。In this paper, the author adopted the ahernant irrigation manner from fact of cucumber production and research the effect on growth, yield and dry matter of cucumber under different irrigation frequency in solar greenhouse. The study show that high frequency irrigation increase remarkably plant height, single plant fruit weight ,average single fruit weight and yield, but decrease stem breadth, accumulation of day matter and WUE of cucumber. It is favorable on the increase of leaf chlorophyll content, accumulation of day matter and WUE of cucumber under the proper irrigation frequency under drip irrigation manner and irrigation frequency six day.
