| 摘 要： | 主要研究了0、80、240、400kg/hm2氮素营养水平下,不同品种黄瓜生长发育以及产量的差异变化。结果表明,叶面积指数、叶绿素含量、叶片及果实中硝酸盐含量随着施氮量的增加逐渐增高;在240 kg/hm2的氮营养水平下,黄瓜的净光合速率、气孔导度均达最大值,产量最高。津青10和吉利十四在不同氮营养条件下的响应基本一致。

| Abstract: | The changes of growth and fruit yield of different cucumber varieties under four level of nitrogen,i.e.,0,80,240,400kg.hm-2 were studied.The results showed that when the nitrogen increased,the leaf area index,chlorophyll content,concentrates of petiole sap of leaves and fruits had gradually advanced.Under the 240kg.hm-2 nitrogen level,the photosynthetic rate,stomatal conductance of cucumber reached the maximum,and the fruit yield was also the highest.'Jinqing 10' and 'Jili Shisi' had the consistent response under different nitrogen conditions. |
