墨西哥落羽杉新无性系区域试验

Regional tests of new clones of Taxodium mucronatum Tenore

在环太湖低洼区、长江滩涂和洪泽湖湿地5 a造林对比试验表明,S201,F11,M3,L226,E106和L293的平均株高、平均胸径和平均单株立木材积在3个试验地均超过2个对照。对墨西哥落羽杉新无性系分类利用进行初步评估认为,宜作为丰产造林的无性系有S201,F11,L226,E106和L293;宜作为农田林网造林的无性系有F11,F65,L226和L293;宜作为园林绿化的无性系有M3,E140,F65,F1,E96和M5。

The five-years＇ Taxodium mucronatum forestation contrast test results showed that such new clones as S201,F11,M3,L226,E106 and L293 performed better than CKs（Clones E3,L294） on the average height,the average breast diameter and the average individual volume growth on the Taihu Lake low-lying area,the Yangtze River shoal and the Hongze Lake wetland.After making a preliminary assessment on Taxodium mucronatum Tenore by the growth conditions,we concluded that Clones S201,F11,L226,E106 and L293 were appropriate for the high-yielding;Clones F11,F65,L226 and L293 appropriate for the farmland shelterbelt,and Clones M3,E140,F65,F1,E96 and M5 appropriate for the landscaping.
