中文摘要 为保障高氏甜龙竹（商品名）苗木质量，提高造林效果，在昆明市嵩明县、富民县，保山市昌宁县，玉溪市元江县开展了播种育苗和扦插育苗试验，以苗高、地径为分级指标研究了高氏甜龙竹1年生苗的分级标准。结果显示，不同地区苗木的分级标准具有一定差异，其中富民县和元江县对Ⅰ级苗的要求较高，富民县Ⅰ级播种苗要求苗高≥8.31 m、地径≥4.63 cm，元江县Ⅰ级扦插苗要求苗高≥6.55 m、地径≥3.67 cm。高氏甜龙竹不同育苗方式，其苗木生长状况存在差异，表现为播种苗的各项生长指标均好于扦插苗，特别是根系的生长状况和每丛株数，播种苗的平均根系数量、根系总质量、每丛株数分别是扦插苗的7.07倍、7.13倍和6.69倍，表明播种苗以后的生长潜力更大。不同等级的高氏甜龙竹苗木的造林效果，无论是播种苗还是扦插苗，Ⅰ级苗的造林成活率均达到100%，Ⅱ级苗的造林成活率也可达到95%以上，Ⅲ级苗的造林成活率均低于82%。

英文摘要 In order to ensure the seedling quality of Dendrocalamus brandisii cv. songmingensis and improve the afforestation effect, seeding and cutting breeding experiments for seedling raising were carried out in Songming county and Fumin county of Kunming city, Changning county of Baoshan city and Yuanjiang county of Yuxi city, and the quality grading standard of one-year-old seedlings of D. brandisii cv. songmingensis was studied with seedling height and ground diameter as grading indexes. The results show that the grading standards of seedlings in different counties are varied. Fumin county and Yuanjiang county have higher requirements for Grade I seedlings. In Fumin county, the standard is seedling height ≥ 8.31 m and ground diameter ≥ 4.63 cm, and Yuanjiang county's standard is seedling height ≥ 6.55 m and ground diameter ≥ 3.67 cm. Different seedling raising methods lead to the differences in seedling growth status of D. brandisii cv. songmingensis, which shows that the growth indexes of the sown seedlings are better than the cutting seedlings, especially the growth status of roots and the number of culms per cluster. The average number of roots, total weight of roots and the number of culms per cluster of sown seedlings are 7.07 times, 7.13 times and 6.69 times higher than cutting seedlings, respectively, indicating that the growth potential of sown seedlings is greater in the later growth. For the afforestation effect of different grades of D. brandisii cv. songmingensis seedlings, the survival rate of Grade I seedlings can reach 100%, whether they are sowing seedlings or cutting seedlings, Grade II seedlings' survival rate can also reach more than 95%, and the survival rate of Grade III seedlings is less than 82%.
