甘肃省不同生态类型区啤酒大麦专用肥施肥技术研究

为完善和细化啤酒大麦专用肥在不同生态类型区的施用技术，降低因过量施肥对啤酒大麦品质和环境的影响。采用多点大田小区试验和室内分析相结合的方法，对甘肃省不同生态类型区啤酒大麦专用肥施肥技术进行研究。结果表明，啤酒大麦专用肥和新动力配施的处理D和处理E增产和改善品质效果最明显，其中处理D平均产量最高为8056.8 kg/hm2，比对照增产194.3 kg/hm2，增加收益426.6元/hm2，其次为处理E平均产量为8024.2 kg/hm2，比对照（处理G）增产161.6 kg/hm2，增加收益364.6元/hm2。根据试验结果，制定出啤酒大麦专用肥在不同生态类型区的施用技术，关外荒漠化和沿山海拔2000 m以上地区的玉门、民乐、山丹基施啤酒大麦专用肥600 kg/hm2，苗期追施新动力120~150 kg/hm2，玉门、永登等属砂质土壤和土层较薄地区，还应配施有机肥；中部和河西绿洲灌区的金昌、武威、景泰施啤酒大麦专用肥600 kg/hm2左右，同时基施或追施75~100 kg/hm2新动力；南部高寒阴湿区施300~450 kg/hm2专用肥即可，不提倡追肥和配施其他肥料。
