不同营养液水培对卡特兰生长发育的影响

[目的]研究不同营养液配方对卡特兰（Cattleya hybrida）生长发育的影响。[方法]采用水培方法,以清水培养为对照。[结果]配方C[0.614 0 mg/L Ca（NO3）.24H2O＋0.283 0 mg/L KNO3＋0.240 0 mg/LNH4NO3＋0.136 0 mg/L KH2PO4＋0.154 0 mg/LMgSO4.7H2O＋0.022 0 mg/L K2SO4＋0.017 0 mg/L K2HPO4＋0.012 0 mg/L NaC l＋31.194 0 mg/L Na2Fe-EDTA＋2.863 0 mg/LH3BO3＋2.1190 mg/LMnSO4.4H2O＋0.230 0 mg/L ZnSO4.7H2O＋0.074 9 mg/L CuSO4.5H2O＋0.024 7 mg/L（NH4）6MO7O2.4H2O]所处理植株的各项形态指标均明显优于其他配方,叶绿素含量也高于其他配方,但丙二醛（MDA）的含量与其他配方相比差异不显著。[结论]该研究可为卡特兰的无土栽培提供科学依据。

Effects of Different Nutrient Solution on the Growth and Development of C.hybrida in Hydroponics

[Objective] The effects of different nutrient solution on the growth and development of C.Hybrida were studied.[Method] The test used solution culture method,and the fresh water was used as control.[Result] The results indicated that different nutrient solution had significant effects on the growth and development of C.hybrida.The plants in formula C solution treatment,0.614 0 mg/L Ca(NO3)·24H2O+ 0.283 0 mg/L KNO3 + 0.240 0 mg/L NH4NO3+ 0.136 0 mg/L KH2PO4+0.154 0 mg/L MgSO4·7H2O+0.022 0 mg/L K2SO4+0.017 0 mg/L K2HPO4+0.012 0 mg/L NaCl+ 31.194 0 mg/L Na2Fe-EDTA+2.863 0 mg/L H3BO3+ 2.119 0 mg/L MnSO4·4H2O+ 0.230 0 mg/L ZnSO4·7H2O+ 0.074 9 mg/L CuSO4·5H2O+ 0.024 7 mg/L(NH4)6MO7O2·4H2O,had better morphological characters and higher content of chlorophyll than that in the other treatments.The content of MDA showed no significant difference in all treatments.[Conclusion] The study can provide scientific basis for soilless culture of C.hybrida.
