摘要
用中山杉３０２、４０１、３０１和“三杉”（池杉、落羽杉、水杉）在江苏北部盐碱地进行多点对比造林，并在造林后６～８、１０和１３年分别进行调查和分析，结果表明：在土壤ｐＨ８．０～９．５，含盐量＜０２％的立地条件下，中山杉３０２综合生长表现最优，４０１次之，３０１、落羽杉、水杉表现中等，池杉表现最差，由此可见，３０２和４０１可作为常规“三杉”造林的更新树种或在低洼碱土和轻盐碱土速生丰产林基地建设中加以发展。
The multilocal plantation of Taxodium ‘Zhongshansa 302’ ( T. distichum×T. mucronatum), ‘Z. 401’( T. ascendens×T. mucronatum ) and Taxodium ‘Z. 301’ ( T. distichum×T. mucronatum ) compared with T. ascendens, T. distichum and Metaseqoia glyptostroboides on salty soils of northern part of Jiangsu Province were investigated and analysed. The result shows that on the soil conditions with pH 8.0～9.5 and salinity<0.2%, ‘Z. 302’ has an excellent synthetic growing appearance and ‘Z. 401’ is only the next to it. ‘Z. 301’, T. distichum and Metaseqoia glyptostroboides are undistinguished while T. ascendens is poor in growing characters. Thus, ‘Z. 302’ and ‘Z. 401’ can be used as tree species for renewing the other two Taxodium species and M. glyptostroboides or developed for the basic establishment of fast growing and high yielding forest.
