摘　　要：以木薯品种华南205和新选048的成熟种茎为材料,采用直插的种植方式,设置4个种茎种植长度处理(20 cm、30 cm、40 cm、50 cm),研究不同种茎长度对木薯各项田间农艺性状的影响。结果表明:就综合出苗率、株高、茎粗、地上部分重、鲜薯条数以及鲜薯产量等各项指标而言,30 cm的种茎种植长度处理具有明显的比较优势。本研究结果将为华南205和新选048在云南木薯生产中的推广提供理论支撑和技术参考。Taken the mature stems of cassava ＂SC205＂ and ＂XinXuan 048＂ as the material, four treatments with different stem cutting length including 20 cm, 30 cm, 40 cm, 50 cm were arranged with vertically inserting cultivation in order to study the agronomic traits influenced.By the indices tested including the seedling emergence rate, plant height, stem diameter, fresh weight above ground, number of tuber, fresh tuber yield, it was concluded that comparative advantage could be obtained from cutting 30 cm long.The results would supply a theoretical foundation and technical reference for the extending of the two cassava varieties in Yunnan.
