摘要
采用裂区设计,以水氮组合设置为主处理、品种设置为副处理,研究了不同水氮组合对不同筋力的优质小麦品种石新733、冀5385、藁8901及高产品系冀2003的产量和植株性状的影响。结果表明:小麦拔节期浇1水或拔节期和开花灌浆期浇2水均能获得较高产量,但春季浇5水的小麦产量却表现减产;浇水次数增加,小麦的功能叶叶长、叶面积增大,比叶重降低;施N量增加,小麦籽粒产量、旗叶长、比叶重和叶面积均增加;施肥量相同时,春季追施1次氮肥处理的小麦产量高于2次分施处理,春季追施2次氮肥处理的小麦比叶重下降、叶面积增加;高产品系冀2003的小麦产量、叶面积和比叶重均高于优质麦品种,优质麦品种间差异不明显。
The effects of different irrigation-nitrogen models on plant yield and plant characters on different gluten wheat cultivars Shixin733, Ji5385, Gao8901 and line Ji2003were studied. The results showed that there was higher yield under irrigating 1 time in stem elongation period or 2 times in stem elongation period and anthesis, but the yield was reduced in irrigating 5 times. More irrigation resulted in lengthening of the functional leaf, increasing of the leaf area and decreasing of specific leaf area. More N used resulted in increasing of the yield, length of flag leaf, leaf area and specific leaf area. Under the same nitrogen quantity, the yield is higher in topdressing nitrogen 1 time than 2 times. The specific leaf area would be decreased, and the leaf area would be improved in topdressing nitrogen 2 times. Line Ji2003 with higher yield characters was superior to the wheat with good quality characters on yield, leaf area and specific leaf area, but there was little difference among the good quality wheat varieties.
