| 摘 要： | 目的:研究重庆渝西紫色土N、P、K不同施用量和不同组合方式对金荞麦根茎产量的影响,探索该类型土壤下的施肥优化方案。方法:采用3414施肥设计方案设计实验,在Excel 2003、SPSS 13.0、Matlab 7.0和Word2003下对数据处理,根据双聚原矢车菊苷元含量评定其品质。结果:不同施肥组合,肥料的有效转化率有差异,其中有效转化率最高组合为N3P2K2,为97.09%,最低组合为N0P2K2,为4.32%;除空白组外,N0P2K2组产量最低为186 kg/667 m2,N2水平15 kg/667 m2,另外两种肥料组合在高、中、低三个水平上差异不大;一元、二元、三元函数拟合效果都较为理想,其中R2值排前三的函数是N、K效应函数、N效应函数和N、P、K三效应函数;不施肥组双聚原矢车菊苷元含量最高为8.67%,高N、高K组其含量降低,但所有的含量均高于7.14%。结论:不同施肥组合,对单一肥料的转化率有一定影响;该类土壤N肥施用量是决定其产量的关键肥料,故应偏重于氮肥施用;可以采用N、K效应函数、N效应函数和N、P、K三效应函数任意一种作为指导该类型土壤的施肥依据;施肥后各组药效成分含量虽然有差异,但...
