川南地区峨眉含笑2年生容器育苗技术试验

Experimental Study on 2-year-old Container Seedling Raising Technology of Michelia wilsonii in Southern Sichuan

为了筛选出最适合川南地区峨眉含笑2年生容器育苗的生长组合,通过育苗正交实验分析基质配比、容器规格和缓释肥量对峨眉含笑苗高地径的影响。结果表明:基质配比对苗高有极显著影响,对高径比有显著影响,对地径影响不显著;缓释肥量对地径和苗高有极显著影响,对高径比有显著影响;容器规格对苗高有极显著影响,对高径比有显著影响,对地径影响不显著。通过综合评价,筛选出最适合川南地区峨眉含笑容器育苗生长的组合为:容器规格采用10 cm×15 cm的无纺布育苗袋,基质配比以椰糠1:泥炭2:土1为基质,缓释肥量为3 kg·m^(−3),可培育2年生苗高87.77 cm,地径10.74 cm的容器苗。

In order to select the most suitable growth combination for 2-year-old container seedling raising technology of Michelia wilsonii in southern Sichuan,the effects of substrate ratio,container size and slow-release fertilizer on the height diameter of Michelia wilsonii seedlings were analyzed by orthogonal experiments.The results showed that substrate ratio had significant effect on seedling height,height-diameter ratio,but no significant effect on ground diameter.The amount of slow-release fertilizer had significant effect on ground diameter and seedling height,and height-diameter ratio.Container size had significant effect on seedling height,height-diameter ratio,but no significant effect on ground diameter.According to comprehensive evaluation,the most suitable combination for containerized seedling growth of Michelia wilsonii in south Sichuan was selected as follows:the container size was 10 cm×15 cm,the substrate ratio of coconut husk 1:peat 2:soil 1,and the amount of slow-release fertilizer was 3 kg·m^(−3),which could cultivate 2-year-old container seedlings with height of 87.77 cm and ground diameter of 10.74 cm.
