摘要
为确定北方平原区脱毒泡桐轻基质容器苗的最佳培育方式,以传统插根育苗为对照,对3种不同脱毒泡桐轻基质容器苗培育方式(A.不覆膜+8 340株/hm2;B.覆膜+8 340株/hm2;C.覆膜+10 000株/hm2)的育苗质量和育苗效益进行了对比。结果表明:与传统插根育苗相比,利用脱毒泡桐轻基质容器苗培育大苗,可避免苗期丛枝病的发生;采用A、B和C脱毒轻基质泡桐苗繁育方式,苗木田间保存率分别比对照提高1.41,1.33和1.23倍,合格苗产出数量分别比对照提高1.52,1.36和1.20倍,经济效益分别比对照提高了1.22,1.86和1.15倍。因此,B模式是最佳的脱毒泡桐轻基质网袋苗育苗模式。
To screen the optimum culture mode adapting to the detoxification paulownia light medium container seedling （DPLMCS） in northern plains region in China,this paper compared and analyzed the influences of three different seedling culture mode which were mode A （ without covering ＋ 8 340 plants/hm2 ）, mode B （ film covering ＋ 8 340 plants/ hm2 ）, mode C （film covering ＋ 10 000 plants/hm2 ） on seedling quality and economic benefit, contrasted to traditional root cuttings of paulownia, adopted the method of field experiment. The results showed that the DPLMCS avoided the paulownia witches broom and the field preserving rate of the DPLMCS increased 1.41,1.33 and 1.23 times, respectively than that of the control. The numbers of qualified seedling of the DPLMCS increased 1.52,1.36 and 1.20 times respectively than that of the control. The economic benefits of the DPLMCS were increased by 1.22, 1.86 and 1.15 times than that of the CK, respectively. Therefore, the mode B is the optimum ways for detoxification paulownia light matrix container seedling.
