摘  要:
为了解杉木连栽土壤中有毒化感物质对杉木幼苗毒害作用 ,采用水培杉木幼苗方法 ,通过投加不同浓度香草醛 ,发现 1mg·kg- 1 香草醛显著抑制杉木种子胚根的伸长 (P<0 .0 5) ,只为对照的 70 % ;香草醛浓度达 1 0mg·kg- 1 时 ,叶绿素总量明显下降到对照的80 % ;超过 2 0mg·kg- 1 对杉木幼苗地径与高度生长产生明显抑制作用 ;50mg·kg- 1 以上将明显影响地上部分枝叶的正常生长发育 ,及至植株冠层的生长 ;超过 1 0 0mg·kg- 1 ,整个植株的生长受到显著抑制 .香草醛是连栽土壤中毒性较大的一种有毒化感物质 ,是杉木存活率低的重要原因之一 .

摘  要:
The hydroponic study on the effect of different concentrations of vanillin on the growth of Chinese fir seedlings showed that 1mg·kg -1 of vanillin significantly inhibited the radicle growth of seeds, reached only 70% of the control; at concentration of 10mg·kg -1 , the total chlorophyll amount was decreased to 80%; when the concentration was above 20mg·kg -1 , the growth of height and diameter at ground layer was inhibited; above 50mg·kg -1 , the growth of branches and leaves of above ground part as well as of the canopy was significantly affected; and above 100mg·kg -1 , the growth of whole Chinese fir seedling was significantly inhibited. It is suggested that vanillin is a kind of more poisonous allelopathic chemicals accumulated in soils continuously planted with Chinese fir, and is one of the important causes making a low survival rate of Chinese fir seedlings.
