摘要: 采用单因子随机区组试验设计探索木薯桂热5号适宜施肥水平。结果表明,100-50-0氮磷钾配比可极显著提高木薯桂热5号的株高(P<0.01)、显著增大种茎的节间距和叶片数(P<0.05),并极显著提高鲜薯产量和淀粉产量(P<0.01);100-50-0是桂热5号最优施肥处理;桂热5号是一个对钾肥需要量较少的耐贫瘠的品种。

关键词: 木薯, 桂热5号, 氮磷钾配比

Abstract: A single factor randomized block experiment design was used to explore the suitable fertilization level of cassava variety GR5. The results showed that the plant height of cassava GR5 was significantly increased(P<0.01),and the internode spacing of stem and leaf number were significantly increased(P<0.05),and the yield and the starch content of fresh tuber root were significantly increased(P<0.01)under the ratio of 100-50-0 “NPK”treatment;100-50-0 was the best fertilization treatment for GR5; GR5 was a barren-tolerant variety that required less potassium fertilizer.

Key words: cassava, GR5, ratio of “NPK”
