不同外源钙物质对蝴蝶兰栽培基质水苔EC值和pH值的影响
Effects of Different Calcium Sources on Values of EC and pH of Sphagnum Moss as Phalaenopsis Medium
摘要
Abstract
In oder to analysis the effects of different calcium sources on the values of EC and pH of sphagnum moss which was used as Phalaenopsis medium,the variety of Phalaenopsis ‘ big chili’ was selected as the research materials in this study.The results showed that the EC value of clear water treatment decreased gradually with the prolongation of time,which dropped to 0.56 mS/cm from 0.92 mS/cm,while the EC value of normal management practices rose gradually,which rose to 1.30 mS/cm from 0.94 mS/cm.Adding CaO could intensify the EC value of the medium continuously with the treatment times increasing,which could reach to 1.35 ～ 1.38 mS/cm and showed a trend to be stable after the fourth time.While adding CaCO3 had no significant effects on the EC value compared with normal management treatment.The pH value of sphagnum moss in the control group decreased gradually with the prolongation of treatment time,and the pH value fell to 4.57 from 4.76 under the condition of clean water and came down to final 4.46 from 4.81 in normal management practices.Calcium addition could change the sphagnum moss pH value obviously which could rise to 4.88～4.91 from 4.74～4.77 with 200～ 600 times CaO treatment.The pH value of adding CaCO3 treatments were all higher than that of the control group,but showed decreasing trend with time.关键词
