气培对黄瓜生理特性影响初报

Preliminary Study on the Influences of Aeroculture on Some Physiological Characteristics of Cucumber

比较气培、水培和土培对黄瓜生理特性的影响。结果表明，气培的黄瓜叶片相对含水量、临界合水量、根系活力均明显优于水培和土培，在采瓜盛期其根系过氧化物酶活力略低于土培，明显低于水培。

Some phpetwical characteristics of cucumberwere compared by using aeroculture, hydroponics and soilcultural methods. The results showed that the reative or crit-ical moisture content of leaves and activity of root system inaeroculture method were obviously better than hydroponicsand soil - culture. on the other hand, Peroxidase activity ofot system at peak of harvesting peried was lower than thatin soil - culture, and significantly lower than that in hydro-ponics.
