不同控水处理对油茶容器苗生长和生理特性的影响

Effects of Different Water Control Treatments on the Growth and Physiological Characteristics of Camellia oleifera Container Saplings

为培育须根发达、生长旺盛的油茶容器壮苗,以‘大别山1号’油茶容器苗为试验材料进行盆栽控水试验,比较不同控水处理条件下油茶容器苗成活率、生长量及生理指标的差异。结果表明,油茶容器苗基质持水量控制在70%~90%时,油茶容器苗成活率、生长势和抗逆性较好。本研究可以为改进油茶育苗技术和提高油茶造林成活率提供参考。

In this paper,in order to cultivate robust Camellia oleifera container saplings with well-developed fibrous roots,container saplings of the cultivar Dabieshan No.1 were used as the test materials and comparative tests were made on the survival rate,increment and physiological index of the saplings with different water control treatments.The results showed that the survival rate,growth potential and stress resistance of the saplings were the best in medium with 70%~90%water content.The study could provide reference for improving the sapling-raising techniques and survival rate of C.oleifera afforestation.
