摘　　要：通过采取不同方式处理插穗、不同扦插密度、不同田间管理方式以及使用不同生长调节剂等进行试验,研究了小青杨在青海高原的繁育技术。结果表明;小青杨在苗期生长速度较快,生长优势显著;吲哚乙酸对苗高生长和地径生长有促进作用,萘乙酸对苗木生根数量有促进作用。The breeding techniques of Populus pseudo-smonii in Qinghai Plateau were studied by using different methods to deal with cuttings,different cutting densities,different field management methods and using different growth regulators. Result shows that the growth of Populus pseudo-smonii is faster at seedling stages and the growth advantage is significant. Indole acetic acid promote the growth of seedling the growth of ground diameter. Naphthylacetic acid promote the rooting of seedling.
