连香树

研究了10年生连香树人工群落8种营养元素的含量、积累分配和循环。

The distribution and circulation of8 nutrient element contents and accumulation in the10a artificial Cercidiphyllum japonicum community were studied .

华西枫杨、连香树树叶干重损失达77%、71%；而米心水青冈和多脉青冈树叶干重损失为43%和42%。

The loss rate of dry weight of Pterocarya insignis and Cercidiphyllum japonicum was77 % and71 % , and shat of Fagus engleriana and Cyclobalanopsis multinervis was43 % and42 % .

施C、N可提高连香树、云杉生活叶C含量，且有随施C量的增加而增大的趋势。

C 、 N disturbances could increase the C content in C. japonicum and P.asperata leaves , and the C content increased with the increasing of the C 、 N disturbances .

野外枯落叶分解试验表明，仅连香树高N干扰对分解有促进作用，其它干扰效果不明显。

The decomposition experiment of withered leaves indicates : only high N disturbance could increase the decomposition of withered leaves of C. japonicum , the other disturbances were not significant .

新乡太行山区秋色叶树种资源较多，开发潜力巨大，其中8种（连香树、盐肤木、卫矛、黄连木、花楸树、红瑞木、四照花、槲树）具有较高的开发利用价值。

Many autumn-leaf trees , specially 8 species have the high development potential in Taihang mountain .

连香树在不同生境条件下，对土壤元素的吸收有一定的选择性。

The tree species in different habitats was found to absorb soil elements selectively to some extent .

主要结论是：（1）连香树营养器官中各种元素的平均含量顺序为Ca>N>Al>K>Mg>P>Fe>Mn。

The results indicate : ( 1 ) The order of average content of elements in organs is Ca > N > Al > K > Mg > P > Fe > Mn .
