| 摘 要： | 在开花坐果期进行了不同根区温度处理(自然地温,15℃,20℃和25℃)对黄瓜生长和生理代谢影响的试验,结果表明,随着根区温度的增加,黄瓜的株高、茎粗、叶片数、叶绿素含量、光合速率、蒸腾速率和产量均显著增加。根区温度的增加显著地减少了植株沤根、黄叶和花打顶的发生,从而显著提高了植株的存活率。

| Abstract: | Cucumber experiments of different root zone temperature treatments(natural root temperature as ck,15℃,20℃ and 25℃) were tested in flower/fruit set period in solar greenhouse.The results indicated that plant height,stem thickness,leaf quantity,chlorophyll content,photosynthetic rate,transpiration rate and yield of cucumbers were all increased significantly with enhanced root zone temperature.Root zone temperature's remarkable increasing could reduce quantity of rotting root plant,yellow leaf and growth bud into flower bud occurrence,and it could improve the surviving rates of cucumber plants. |
