摘要
采用正交旋转组合设计,针对氮、磷、钾、锌四种肥料对小麦产量和品质的效应进行探讨,结果表明:氮磷对产量都达显著正效应,氮对湿面筋含量达极显著正效应,磷与湿面筋含量呈显著负效应,钾锌对产量和品质效应微弱,四种肥料对产量的影响顺序为:氮>磷>锌>钾,对湿面筋含量的影响顺序为:氮>磷>钾>锌。小麦产量和品质都较理想的施肥区间为氮252 8~294 2kg/hm2,磷111 0~139 1kg/hm2,钾145 8~153 0kg/hm2,锌9 8~12 1kg/hm2,合理的配比为N P2O5 K2O ZnSO4=1 0 46 0 55 0 04。
The effects of four kinds of fertilizer such as nitrogen phosphate potassium zinc on the yield and quality of wheat were studied by applying the orthogonal rotary designThe results indicated that correlations between N、P and yield,N and wet gluten content were significantly positive, but the correlations between P and wet gluten content were significantly negative,and there was no significantly correlations between K 、Zn and yield,K、Zn and qualityAccording to analysis of the function model, the yield responses to the four factors were in order of N>P>Zn>k,and wet gluten content responses in order of N>P>K>Zn.Analysis shows the reasonable yield and quality were obtained when the N level was 2528~2942kg/hm2、P2O5 1110~1391 kg/hm2、K2O 1458~1530 kg/hm2、ZnSO4 98~121kg/hm2,and the proportion of N、P2O5、K2O and ZnSO4 were 1046055004
