摘　　要：[目的]建立乳源木莲轻基质网袋育苗技术体系,提高乳源木莲造林速度、成活率和育苗产量。[方法]通过L_9(3~4)正交试验设计比较2种育苗基质3个水平梯度和1种追肥种类3个水平浓度对乳源木莲苗木苗高、地径、地上部分(干、枝、叶)和地下部分(根系)等形态指标的影响。[结果]在轻基质网袋基础基质中即泥炭土∶珍珠岩∶蛭石=3∶2∶1加入1份松针土能提高苗木的各项生长指标水平,而稻谷壳的加入未达到良好的促进效果;从6月中旬开始,追肥以水溶肥的形式加入6 g/株磷酸二氢钾,能显著提高苗木的各项生长指标。[结论]乳源木莲轻基质网袋育苗能达到良好的育苗效果。[Objective]In order to establish the light substrate net bag seedling raising technology system of Manglietia yuyuanensis Law and improve the afforestation speed,survival rate and seedling yield of Manglietia yuyuanensis Law.[Method]Through L 9(34)orthogonal test design,the effects of three horizontal gradients of two seedling raising substrates and three horizontal concentrations of one top dressing species on the seedling height,ground diameter,aboveground part(stem,branch,leaf)and underground part(root)of Manglietia yuyuanensis Law seedlings were compared.[Result]The results showed that adding 1 part of pine needle soil in the light matrix(peat∶perlite∶vermiculite=3∶2∶1)could improve the growth index level of seedlings,but the addition of rice husk could not achieve a good effect;from the middle of June,the top dressing was added with 6 g/plant potassium potassium dihydrogen phosphate in the form of water-soluble fertilizer,which could significantly improve the growth indexes of seedlings.[Conclusion]The light substrate net bag seedling of Manglietia yuyuanensis Law can achieve good seedling raising effect.
