【摘要】 以金心吊兰为材料,将生长状况大致相同的金心吊兰放在3种不同成分和不同浓度的营养液中进行比较实验,观测不同处理植株的叶片数、根长、根数、株高、茎粗及叶绿素含量、光合速率、蒸腾速率,筛选出最适合金心吊兰生长的溶液,结果表明:最适合吊兰生长的是B配方T1浓度的营养液.更多还原

【Abstract】 The growing effects of Jinxin chlorophytum comosum in different nutrient solution have been studied in this paper.Put Jinxin chlorophytum comosum with basically identical growth situation in the 3 kinds of nutrient solutions of different components and concentration to carry out the parallel experiment.Observed the form index of the different treatment plants:The number of bladders,length of roots,the radical,height,rude of stem and Chlorophyll contents,brightness close the rate,the rising rate,the change of PH value and conductance lead in the solution,Sift out which solution is most suitable for Jinxin chlorophytum comosum’s growth.The results show that the most suitable solution for Jinxin chlorophytum comosum’s growth is T1 concentration of B solution.更多还原
