摘要: [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[0.6140 mg/L Ca(NO3)·24H2O+0.2830 mg/L KNO3+0.2400 mg/L NH4NO3+0.1360 mg/L KH2PO4 +0.1540 mg/L MgSO4·7H20 +0.0220 mg/LK2SO4 +0.0170 mg/LK2HPO4 +0.0120 mg/L NaCl+31.1940 mg/L Na2Fe-EDTA +2.8630 mg/L H3BO3+2.1190mg/L MnSO4·4H2O + 0.2300 mg/L ZnSO4·7H20+ 0.0749 mg/L CuSO4·5H2O+ 0.0247 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.
英文摘要: [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 ...
