不同容器对香榧育苗质量的影响

Effects of Different Containers on the Qualities of Torreya grandis Seedlings

在徽州区香榧育苗基地开展了不同容器培育香榧苗木试验。结果表明,黑色塑料容器培育的香榧苗,高、径生长高于白色无纺布容器苗,但多年生的根系易沿容器底壁旋转,较易感染病害;白色无纺布容器苗根系生长未见旋转,苗木病害感染低,总体质量较高。

An experiment was carried out using different containers to cultivate Torreya grandis seedlings in Huizhou District, HuangshanCity. The results showed that the height and stem-diameter growth of the seedlings cultivated in black plastic containers were higher thanthat of the seedlings cultivated in white nonwoven ones, but the perennial root systems cultivated in black plastic containers were likely torotate along the bottom wall of the containters and more susceptible to disease infection while those cultivated in nonwoven containersdidn’t rotate and the seedlings had low disease infection, showing higher overall quality.
