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+49.3548x1x2-0.0648x12-75075000x22,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。
The effects of potassium and manganese fertilization on the quality and yield of winter wheat in dryland were studied in the cinnamon soil area of western Henan. The results showed that potassium and manganese fertilization, wheat wet gluten content, sedimentation value, settling time, protein content and protein yield all increased to some extent. The analysis of variance of wheat quality index indicated that the difference of different potassium levels reached extremely significant level, and the levels of manganese fertilization did not reach significant level except for protein yield. The regression model of potassium (x1) and manganese (x2) combined with wheat yield was: y = 3471.6879 + 12.4313x1 + 318495x2 + 49.3548x1x2-0.0648x12-75075000x22, the highest yield was based on 96.7kg / hm2K2O Spraying mass percent concentration of 0.2% manganese sulfate.
