| 摘 要： | 以辽西地区造林常用树种侧柏和油松幼苗为研究对象,通过不同的土壤水分胁迫来比较两种树苗的生长指标的变化。结果表明:侧柏幼苗的株高和地径随土壤含水量的增加而增加;油松幼苗株高虽然随土壤含水量的增加而增加,但是地径在初期变化不显著,后期生长缓慢,以60%的土壤含水量处理增加最多。

Effects of Water Stress on Growth of Platycladus orientalis and Pinus tabuliformis |
| |
| Abstract: | Taking afforestation common species (Platycladusorientalis and Pinustabuliformis)in western Liaon-ing Province as research obj ects,variation of growth indices of two seedlings was compared by different soil stress. Result shows that seedling height and ground diameter of Pinustabuliformis increase with the increase of soil water content;seedling height increase with the increase of soil moisture;ground diameter did not change significantly in the initial stage and grow slowly in the later stage;the ground diameter increase more by adopting the treatment (60% soil water content ). |
