摘    要:研究了不同钾肥用量对地膜覆盖小南瓜产量和贮藏特性的影响.结果表明,施用钾肥能够增加小南瓜叶片的叶绿素含量,提高叶片光合速率;使茎秆粗壮,明显提高小南瓜的产量,延长小南瓜采收后的贮藏时间,提高贮藏品质.在本试验范围内,小南瓜田间的适宜施钾量(K2O)为121.5 kg/hm2.

关 键 词:钾营养  地膜覆盖  小南瓜  产量  贮藏

Abstract:This paper studied the effect of potassium nutrition on yield and storing characteristic of small cushaw under plastic film mulching.The result showed that chlorophyll content and photosynthetic rate in leaves of small cushaw increased as applying potassium fertilizer.The stem width and yield and storing time and quality of small cushaw were significantly increased,too.The optimum fertilizer potassium level was 121.5 kg/hm2 in this study.
Keywords:Potassium nutrition  Plastic film mulching  Small cushaw  Yield  Storing
