杂种马褂木幼林生产潜力初步分析

Preliminary Analysis of Production Potential of Young Plantation in L.Chinense × L.Tulipifera

对幼林杂种马褂木人工林进行了调查、分析,结果表明,杂种马褂木在福建省生产潜力较大。试验林生长较迅速,树高年平均生长量达0.79m,胸径达1.4cm;5年生时平均树高达3.92m,胸径达4.7cm。杂种马褂木适应性强,5年生时保存率高达99.00%以上,且生长稳定。杂种马褂木对立地条件要求不高,但对水分反应敏感,生长期内降水不足将明显影响其生长,应选择降水充足的林地造林。

Yong Plantation of L.Chinense×L.Tulipifera was analyzed.The result showed that L.Chinense×L.Tulipifera had production potential for Fujian province,China.The plantation grows well,average annual growth of tree height could get 0.79m and that of DBH was 1.4cm.When the plantation was 5 years old,the average height and DBH was 3.92m and 4.7cm,separately.And,the save rate was more than 99.00%.L.Chinense×L.Tulipifera was adaptable,and had stable growth.But it was sensitive to water;it would be poor growth if there were no sufficient precipitation in the growth period.Woodland which had sufficient precipitation was suitable for planting with L.Chinense×L.Tulipifera.
