| 摘 要： | 目的]提高红皮树容器育苗的出苗率、成苗率和移栽成活率,为其开发利用提供优质苗木。方法]设计3种基质配方3、种穴盘规格、不同配比的肥料在2种光照强度下进行红皮树穴盘育苗试验,探索红皮树穴盘育苗技术。结果]泥炭+珍珠岩、森林腐殖土+黄心土、树皮粉+黄心土3种基质配方均较适合红皮树穴盘育苗。苗木生长与穴盘容积呈正比。不同生长期肥料配比与苗木质量关系密切。加盖60%透光度遮阳网处理的苗木生长正常,质量指数比全光照处理高27.3%。结论]培育半年红皮树苗可选用72S型育苗,1年苗可选用林50T型育苗,困难地造林可选用林72T型育苗。苗木速生期和生长后期宜按一定配比施用N∶P∶K液肥。

| Abstract: | Objective] The aim of study was to improve the emergence rate,seedling rate and transplanting survival rate of container seedling of S.suberifozius,and provide seedling with high quality for its development and utilization. Method] With the design of 3 media formulas,3 plug sizes and different ratio of fertilizer under 2 light intensities,the plug-seedling of S.suberifozius experiment was conducted to explore the plug-seedling technique.Result] The 3 media formulas of peat + pearlite,forest humic soil + yellow soil and bark powder + yellow soil were all fit for plug-seedling of S.suberifozius.The seedling growth was positively related to the dish volume.The ratio of fertilizer had close relation with seedling quality at different growing stages.The seedling grown normally in covering of shading net with 60% transmittance and its quality index was higher 27.3% than that of total light treatment.Conclusion] The 72S type seedling could be chosen to cultivate the half year old one of S.suberifozius,and 50T type was chosen for 1 year old seedling of S.suberifozius,72T could be selected for difficult afforestation land.A certain ratio of N∶P∶K liquid fertilizer should be applied at fast growing period and late growth period. |
