| 摘 要： | 对１年生杉木苗培养液的ｐＨ、电导率和有机碳含量的测定表明：经过杉木苗培养后的各营养液的ｐＨ均有下降趋势，其中以硝态氮营养液下降幅度最大（下降１．７２），其次是缺锌营养液（下降１．６８），最小为缺磷营养液。各种营养液的电导率变化较复杂，缺磷、缺锌和对照处理电导率增大，而硝态氮、混合氮和缺铁处理下降。杉木苗分泌有机碳以对照组最多，缺铁培养的分泌最少。

| Abstract: | Determination on pH, eletrical conductivity and organic carbon content of culture solutionfor 1-year Cunninghamia lanceolata resulted that there was a tendeacy of pH decrease of culturesolution after cultivation of C. lanceolata, especially nitrate-N(by 1. 72 ), non-zinc soluftion(by1. 68)and non-phosphate one. The change of electrical conductivity was complicated,non- phosphate, non-zinc and control increased while nitrate-N, mixed nitrate and non-irontreatment decreased. Organic carbon secerned the most by C. lanceolatla seedling treated bynon-treatment, the less by non-iron solution. |
