摘要
研究了不同钾肥用量对日光温室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,提高光合速率;也能使茎秆粗壮,明显提高小南瓜的产量,延长小南瓜采收后的贮藏时间。在本试验范围内,小南瓜的田间适宜施钾量(K2O)为81 kg/hm2。
The effect of potassium nutrition on the yield and store characteristic of small cushaw in solar greenhouse was studied in this paper. The result showed that chlorophyll content and photosynthetic rate in leaves of small cushaw increased with the application of potassium fertilizer. The stem width, yield and store time of small cushaw were significantly increased too. The optimum K2O level was 81 kg/hm^2 in this study.
