【摘要】 根据史密斯施桉(Eucalyptus smithii)苗期生长规律,设计不同容器类型试验,系统研究无底容器育苗对移植后90 d的苗木质量的影响(即幼苗从苗床移植到容器生长90 d后)。结果表明:无底袋容器苗比有底容苗在苗高、根颈直径、叶片数、叶面积和植株总干重分别提高了13.0%,21.7%,28.1%,11.8%,16.6%。无底容器苗的地上干物质分配指数(86%)高于有底袋苗(84.5%)。更多还原

【Abstract】 Based on the growth rules of Eucalyptus smithii seedlings,the experiments were conducted with different containers to research the influence of the bottomless container on quality of seedlings for 90 days after transplanting was carried out.The results showed that the seedling height,diameter of root neck,leaf number,leaf area,dry weight per seedling of the bottomless container were 13.0%,21.7%,28.1%,11.8%,16.6%,respectively,obviously higher than those of the bottom container.The shoot dry matter partitioning index(86%) of the seedling of bottomless container was higher than that(84.5%) of the seedling of the bottom container.更多还原
