摘要
观测了黄瓜生长动态与生理特性对土壤水分状况的反应 .结果表明 ,日光温室嫁接与未嫁接黄瓜分别在土壤相对含水量 70 %和 80 %时株高、叶面积和产量增长最快 ,土壤水分过高与过低均不利于黄瓜的生长 ;随土壤含水量降低 ,叶片光合速率、气孔导度、水势与根系活力均下降 .
Studies on the effect of soil water on the growth and physiological characteristics of cucumber in greenhouse showed that water deficit or excessiveness could retard the growth and development of cucumber. The transpire rate, Gs, water potential and root activity decreased quickly due to water deficit.
