Abstract:

?为探究油菜(Brassicacampestris)-冬小麦(Triticumaestivum)轮作下冬小麦的粮饲兼用性能,在黄土高原塬区,对油菜后茬冬小麦(BW)和休闲后冬小麦(FW)系统中冬小麦‘陇育216’分别进行冬季刈割(Cut1)、春季刈割(Cut2)和不刈割(Uncut)处理,测定了冬小麦生育期水分状况、刈割所得饲草产量和品质以及收获期籽粒产量等。结果表明,1)BW轮作条件下,两次刈割处理下所得饲草产量均高于FW,但处理间饲草的营养指标均无显著差异(P>0.05);BW轮作条件下,Cut2所得饲草产量极显著高于Cut1(P<0.01),且Cut1和Cut2所得饲草粗蛋白含量均高于20%,相对饲喂价值高于151%,但微量元素含量较低,不能满足家畜的日常需求。2)与FW相比,BW轮作条件下的冬小麦籽粒产量均减少,尤其Cut2导致显著减产20.9%(P<0.05),主要表现为单位面积穗数显著减少;BW系统中,Cut1和Cut2籽粒产量均低于Uncut,但无显著差异,且Cut1减产程度大于Cut2。油菜-冬小麦轮作系统中冬小麦粮饲兼用可提供大量优质饲草,而籽粒减产不显著,增加了系统产出,且冬小麦作为饲草利用最佳时间为春季。
