| 摘 要： | 采用设置田间小区的试验方法,在贵州黔中地区研究不同氮磷钾配方在甘薯上的应用效果。结果表明:不同处理对甘薯的生长影响不同,配方施肥对甘薯分支数,薯蔓长,生物量等都有明显促进作用;甘薯施用氮磷钾肥要适量,可适当施用农家肥,肥料配方为纯N 135 kg/hm2、P2O567.5 kg/hm2、K2O 202.5 kg/hm2时产量最高,比对照增产22.12%,因此,建议该区在生产甘薯采取该配方,以获得较好增产效果。

| Abstract: | For study the effects of different formula fertilization on sweet potato,a field experiment was carried in central Guizhou.The results showed that: formula fertilizer application can significant increasing the branch,the sweet potato vines,the biomasses and so on.In different treatment,the effects were different;Applying fertilizer should be appropriate,suitable application of manure is useful.The highest yield was obtained when recommended amount was adopting N135 kg/ha、P2O567.5 kg/ha、 K2O 202.5 kg/ha for sweet potato in this area.Compared to the CK,it was increased 22.12%.Following the recommendation will get high yield. |
