红苞木引种试验

优良阔叶树种红苞木引种到广东省怀集县后，生长迅速，适应性强。种植于条件好的立地，16．5年生时平均树高11．8m，平均胸径15．9cm，蓄积量270．304m3/hm2，比作对照的本地树种马尾松的蓄积量大46．4％；在条件较差的立地，16．5年生时蓄积量也有126．712m3/hm2，比对照木荷的蓄积量大34．2％。引种的林分自然更新良好，天然下种的幼树生长良好；萌芽力强，可萌芽更新。该树种可作为用材林、生态公益林和风景林树种大力推广。

INTRODUCTION EXPERIMENT OF RHODOLEIA CHAMPIONII

Rhodoleia championii was introduced into Huaiji county, Guangdong province in 1986 and the experiment results shows that the introduction are successful. Planted in high quality site, the tree height of 16.5 years old stand reaches 11.8 m, the D.B.H. is 15.9 cm, the volume is 270.304 m 3/hm 2, it is 46.4% more than the volume of the Pinus massoniana stand that planted as the contrast. Planted in general site, the volume of 16.5 years old stand reaches 126.712 m 3/hm 2, it is 34.2% more than the Schima superba contrast. The stand can natural regenerate well, the sapling from natural seed grows well. The stand also showed strong sprout ability and can regenerate from sprouts. The species is worthy to being widely planted.
