| 中文摘要: |
| 在豫西褐土区研究了钾锰配施对旱地冬小麦品质和产量的影响。结果表明:钾锰配施、小麦湿面筋含量、沉降值、稳定时间、蛋白质含量及蛋白质产量均有不同程度增加。通过对上述小麦品质指标的方差分析表明,不同施钾水平的差异达到了极显著水平,不同施锰水平除蛋白质产量外均未达到显著水平。钾(x1)锰(x2)配施小麦产量的回归模型为:y=3471.6879+12.4313x1+318495x2+49.3548x1x2-0.0648x21-75075000x22,最高产量施肥量为基施96.7kg/hm2K2O的基础上,配合喷施质量百分比浓度为0.2%的硫酸锰。 |
| 英文摘要: |
| The effect of potassium and manganese fertilizer cooperating application on quality and yield of winter wheat in dryland in the cinnamon soil area in westen Henan Province was studied. The results showed that cooperating application of potassium and manganese fertilizer could increase sedimentation value , protein yield, the content of wet gluten and protein, and prolong the dough stable time. The results of Duncan's test on the quality of wheat showed that difference among the main treatments (application rates of potassium fertilizer) reached the very significant level, but difference among the subtreatments (concentrations of manganese fertilizer) was not significant except the protein yield. The regression model of wheat yield with potassium and manganese fertilizer was y=3471.6879+12.4313x1+318495x2+49.3548x1x2-0.0648x21-75075000x22. The application rate for maximum yield was 96.7 kg/hm2 K2O cooperated with foliage dressing of manganese fertilizer (0.2%). |
