| 摘 要： | 2007年在合浦县乌家镇西大村开展了木薯良种华南5号田间“3414”肥效试验，结果表明：供试田块的整体地力属中低水平，土壤中有效养分含量丰缺程度表现为低N、中P、中K；在该地力条件下，以处理6（纯N165．0kg／ha，P2O5 60．0kg／ha，K2O 120．0kg／ha）的产量最高，为28852．3kg／ha。根据效应模型分析得出N、P、K的互作效应为：N、P和N、K正互作，P、K负互作；单元素对产量的作用效果是N〉P〉K。应用多元回归方程分析结果，得出该区域种植木薯华南5号的最佳施肥量（纯N141．5kg/ha，P2O5 36．5kg／ha，K2O 124．4kg／ha）和最佳产量（27094．8kg／ha），可用于指导木薯生产。

| Abstract: | The experiment has been carried out to perform the fertilizer test ＂3414＂ on cassava variety SC 5 in year 2007 at Xida Village of Wujia Town, Hepu County, Guangxi, China. The soil was found to have low N, medium P and medium K contents. The highest yield of cassava was found 28852.3 kg/ha when treated with T6 （pure N @165.0 kg/ha, P2O5 @ 60.0 kg/ha, K2O @ 120.0 kg/ha）. The results of effect-model analysis on interaction of N, P, K indicated that N was positively related to P and K, and P was negatively related to K. The effect of single-element on yield of cassava was in order of N〉 P〉 K. Multiple regression equation analysis revealed that the best fertilizer application was pure N @141.5kg/ha, P2O5 @36.5 kg/ha, K2O @124.4 kg/ha that resulted in highest yield （27094.8 kg/ha） of cassava. |
