摘要
试验采用3 a生思茅松嫩枝为材料,以红心土为基质在营养袋中扦插。对其生根性状进行分析得出,地上部分生物量与地下部分生物量呈显著正相关性,与不定根平均长度呈显著负相关性;地下部分生物量与不定根数量呈显著正相关性。
The cuttage with young branches of three - year - old Pinus kesiya var, I angbianensis in nutritional bag filled with red soil were studied, the results showed that the aboveground biomass was significantly and positively correlated with the underground biomass, and was significantly and negatively correlated with average length of adventitious roots, the underground biomass was significantly and positively correlated with the average number of adventitious roots.
