延长通风时问与增施C02对温室生态因子及黄瓜光合特性的影响研究

Effects of prolonging ventilation time and enriching CO2 in greenhouse on the ecologic factors and photosynthetic rate of cucumber

    摘要
  • 摘要: 研究延长通风时间(4h／d)并增施C()2对温室黄瓜光合作用的影响结果表明，与对照相比，延长通风时间使通风时段内平均CO2浓度升高43．80uL／L，平均温度和湿度分别降低2．40℃和350Pa，黄瓜叶片露时约缩短2．5h／d；延长通风时间与增施CO2使黄瓜平均光合速率分别提高1．63>umol／m2·s和3．33>umol／m2·s，浞进光合产物积累。

     

    Abstract: The effects of prolonging ventilation time and enriching CO2 in greenhouse on the photosynthetic rate of cucumber were studied．The results show that prolonging ventilation time increases the CO2 concentration by 43．80uL／L，decreases the temperature，humidity and the leaf dew duration by 2．40℃ ，350Pa，and 2．50h／d，respectively．Prolonging ventilation time and enriching CO2 increase the average of photosynthetic rate by 1．63>umol／m2·S and 3．33umol／m2·S，respectively and increase the accumulation of the photosynthetic product．
