[目的]解决我国特有物种南川木波罗人工栽培过程中种子发芽率低,裸根苗移栽困难的难题,为实现南川木波罗较大规模的人工繁育栽培提供技术支撑。[方法]试验通过采用不同的种子处理方式和不同的育苗方式研究了南川木波罗的种子发芽率和出苗率情况。[结果]不管在沙床还是直播黄壤,处理Ⅱ的种子的发芽率、成苗率和总出苗率均高于处理Ⅰ和处理Ⅲ,其比直播黄壤高出分别为1.5%、16.27%和13.95%,相比轻基质容器育苗的总出苗率高2.46%。8种轻基质配方育苗结果显示,配方8的苗木生长情况最好,其出苗率和苗高、地径生长均与其他配方差异显著,其次是配方1和3,配方7的出苗率和苗高、地径生长情况最差。[结论]建议生产条件允许情况下,采用泥炭+森林表土=6:4(8号处理)或草甸土+蛭石+黄心土=5:3:2(1号处理)、草甸土+珍珠岩+黄心土=5:3:2(3号处理)开展轻基质育苗。
[Objective] The research aimed to solve the problem of low seed germination rate and difficult transplanting of bare root seedlings in Nanchumbo Polo artificial cultivation in China, and provide technical support for large-scale artificial breeding of Nanchong Polo. [Method] The seed germination rate and seedling emergence rate of Nanchuangboluo were studied by using different seed treatment methods and different seedling raising methods. [Result] The germination rate, the seedling emergence rate and the total seedling emergence rate of seed treatment Ⅱ were higher than those of treatment Ⅰ and treatment Ⅲ, respectively, which were 1.5%, 16.27% and 13.95 higher than that of direct seeding yellow soil, respectively %, Compared with 2.46% for the total emergence rate of seedlings raised in light substrate containers. The results of seedling raising showed that formula 8 had the best growth of seedlings, and its emergence rate, seedling height and diameter growth were significantly different from those of other formulas, followed by formulas 1 and 3, and the emergence rate and seedling height of formula 7 , The worst growth path diameter. [Conclusion] If peat + forest topsoil = 6: 8 (treatment No.8) or meadow soil + vermiculite + Huangxin soil = 5: 3: 2 (treatment No.1) and meadow soil + pearl Rock + yellow heart soil = 5: 3: 2 (No. 3 treatment) to carry out light substrate nursery.
