摘  要:
通过对赤桉苗木进行3个水分胁迫强度,4个水分胁迫循环周期的试验,研究其对赤桉苗木的生长及生物量的影响。结果表明:不同水分胁迫强度和次数对赤桉苗木生长、生物量极其分配的影响显著,赤桉在水分胁迫下,生长受到抑制,根占总生物量的比例随水分胁迫梯度和次数的加大而增加;在不同的水分胁迫下,以间隔10天浇水的处理为最佳的水分胁迫梯度,第二循环周期为最适胁迫周期。

摘  要:
The effect of water stress on the growth and biomass of seedlings of Eucalyptus camaldulensis Dehnh was studied through potted experiment(three different water stress,four cycles).The results showed that:the effect of water stress on growth and biomass of Eucalyptus camaldulensis Dehnh Seedling is significantt,and the high growth was inhibited,but the allocation of biomass to root increased with extending stress intensity.Among them,ten-day watering for the best water stress,second cycle period for most suitable coercion cycle.
