不同营养液水培对蟹爪兰的生长影响

Effects of Different Nutrient Solution on the Growth of Zygocactus truncatus with Water Culture

以蟹爪兰为试材,设立4个霍格兰营养液水平(1/4营养液、1/2营养液、3/4营养液、全营养液)和清水对照,进行水培蟹爪兰的形态、生理指标的测定。结果表明:蟹爪兰在清水中也能存活并生长,添加营养液可促进蟹爪兰的水培生长,但是1/2浓度霍格兰营养液处理比其它浓度营养液对蟹爪兰生长的促进作用更为明显。

Using Zygocactus truncatus as the materials,set four nutrient levels of Hoagland＇s（1/4,1/2,3/4 and full nutrient solution） and compared with pure water hydroponic.Through the determination of related morphological parameters and physical signs.The results showed that Zygocactus truncatus could survive and grow in pure water.Adding nutrient could promote the Zygocactus truncatus＇s growthing in hydroponic.And the 1/2 concentration of the nutrient processes was the most obvious favorable to Zygocactus truncatus＇s growing than the other treatments.
