摘要: 通过对温室黄瓜不同水分处理植株的生长、蒸腾以及光合特性的观测和分析,得出:根际含水量为80%~90%时植株的生长状态、光合特性、根系吸水速率以及产量均为最大,说明此含水量水平为温室黄瓜生长期的最优含水量,过高或过低均会对植株的生长发育造成不良影响,使最终产量降低。另外试验观测还发现,水分过量不仅使植株生长发育迟缓,产量水平降低,可能还是诱发根结线虫病的原因。

Abstract: Experiment results displayed that 80%~90% was a optimum water content for cucumber (cucumis sarivus)growth and physiological characteristics and yield in greenhouse, water deficit or excessiveness would retarded the growth and development of cucumber, and
