摘要
[目的]筛选节水耐旱黄瓜品种,进一步推广利用.[方法]比较目前北京地区主推的16个黄瓜品种在3个不同灌水量条件下的生长情况、光合特性、产量、水分利用效率等指标.[结果]对设施黄瓜进行水分胁迫处理,京研夏美嫁接苗、北京403嫁接苗、中农26嫁接苗为高产、高水分利用效率的栽培品种.同时,京研绿玲珑嫁接苗随着灌水量减少,产量减少率最小,在采收后期仍能保持较好的瓜形和品质,也是较好的节水品种.[结论]京研夏美嫁接苗、北京403嫁接苗、中农26嫁接苗、京研绿玲珑嫁接苗是北京地区较好的温室节水品种.
Abstract
[Objective] To identify and further spread cucumber varieties with drought tolerance and water-saving.[Method] Growth,photosynthetic characteristics,yield,water use efficiency of 16 cucumber varieties which promoted in Beijing under three kinds of irrigation water were compared.[Result] The result showed that grafted cucumber varieties of Jingyanxiamei,Beijing 403,Zhongnong 26 had higher yield and higher water use efficiency under water stress.Meanwhile,as the irrigation decreasing,Jingyanlvlinglong grafted cucumber had minimum yield loss,it can still keep better shape and quality at late harvest.[Conclusion] The grafted cucumber of Jingyanxiamei,Beijing 403,Zhongnong 26,Jingyanlvlinglong are the better greenhouse water-saving varieties in Beijing.
