摘要：

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。

Abstract:

To improve and refine the fertilization of malting barley special fertilizer of application technology area in different ecological zones, to reduce the quality and environmental of impact due to excessive fertilization of malting barley. Study on fertilization of malting barley special fertilizer combining with the multi-point field plot experiments and analysis in laboratory in different ecological areas in Gansu Province. The results showed that there existed significant yield and quality improvements in combined application of specialty fertilizer for beer barley and Xindongli in treatments D and treatment E. The average yields reached 8056.8 kg/hm2 for treatment D, the yield was increased by 194.3 kg/hm2 and the income 426.6 yuan/hm2 compared with CK; and secondly for treatment E whose average yield was 8024.2 kg/hm2, increased by 161.6 kg/hm2 and the income by 364.6 yuan/hm2 compared with CK. Specialty fertilizer application technologies for beer barley in different ecological areas were determined based on the experimental results: basal application of 600 kg specialty fertilizer per hm2 and additional application of 120-150 kg Xindongli per hm2 in seedling stage were optimum amounts for Yumen, Minle, Shandan, ect. in desertification areas and mountain areas with an altitude of above 2000 m, organic fertilizer should be applied to preserve soil moisture and fertility in Yumen, Yongdeng, etc. where the soil was sandy and infertile; 600 kg specialty fertilizer per hm2 for basal application, furthermore basal applying or topdressing of 75-100 kg Xindongli per hm2 for beer barley were recommended in Jingchang, Wuwei, Jingtai, etc. in Hexi oasis irrigation areas; and for southern cold and damp mountain areas, it could be applied 300-450 kg specialty fertilizer per hm2 without any topdressing and mixture with other fertilizers.
