摘  要:
采用311-A最优设计与田间试验方法,研究了氮、磷、钾施肥用量对马铃薯产量和淀粉含量的影响,建立了宁夏雨养农业区马铃薯产量、淀粉含量与氮、磷、钾施肥用量之间的数学模型。分析了马铃薯产量及淀粉含量试验因子的主效应和互作效应,优选了马铃薯目标产量在30000 kg/hm2时最高产量的最佳施肥量组合为氮、磷、钾(kg/hm2):267.3-139.0-82.1,最佳经济施肥用量组合为氮、磷、钾(kg/hm2):258.6-131.1-71.1;淀粉含量最高时最佳组合氮、磷、钾( kg/hm2):183.9-106.4-87.6。

摘  要:
In this study, the effects of nitrogen, phosphorus and potassium application on yield and starch content of potato plants were investigated by 311-A regression design in rainfed agricultural area in Ningxia province. Mathematic models be-tween yield and starch content and the parameters of nitrogen, phosphorus and potassium amount used were built. Mean-while, the main factor and interaction factor affected yield and starch content were analyzed. The results showed that the op-timum nitrogen, phosphorus and potassium application amount to acquire the highest yield was 267. 3, 139. 0 and 82. 1 kg/hm2 , respectively, to acquire the highest economic value was 258. 6, 131. 1 and 71. 1 kg/hm2 , respectively, to acquire the highest starch content was 183. 9, 106. 4 and 87. 6 kg/hm2 , respectively.
