摘　　要：为了探索不同棱型不同株高大麦品种混种的最佳组合,以保山市大面积推广的二棱矮秆品种‘82-1’、‘保大麦22号’,多棱中高秆品种‘保大麦8号’、‘保大麦14号’、‘保大麦15号’、‘保大麦25号’为材料,设10个处理,进行单种和不同混种组合比较试验,结果表明:(1)混种较单种二棱矮秆高产品种增产3.1~14.3%;(2)混种最佳组合为二棱品种‘82-1’混种多棱品种‘保大麦25号’,其次是二棱矮秆品种‘保大麦22号’混种多棱品种‘保大麦25号’,基本苗比例为6:4;(3)混种选择品种时,二棱品种‘82-1’优于‘保大麦22号’,多棱中高秆品种‘保大麦25号’最优,‘保大麦8号’、‘保大麦14号’次之,不宜选择‘保大麦15号’。To find out the best combination of barley varieties with different row types and plant heights,comparative trials of single species and different hybrid combinations were carried out with 10 treatments on the following widespread barley varieties in Baoshan:two-row short-stalked‘82-1’and‘Baodamai 22’,and multi-row medium-stalked and long-stalked‘Baodamai 8’,‘Baodamai 14’,‘Baodamai 15’and‘Baodamai 25’.According to the results,(1)compared with the single species,hybrid two-row short-stalked highyielding varieties show an increase of 3.1%-14.3%in yield;(2)the best hybrid combination is the two-row variety‘82-1’with the hybrid multi-row variety‘Baodamai 25’,followed by the two-row short-stalked variety‘Baodamai 22’with the hybrid multi-row variety‘Baodamai 25’,and the ratio of basic seedlings is 6:4;(3)among hybrid varieties,the two-row variety‘82-1’is better than‘Baodamai 22’;among multi-row varieties,the long-stalked variety‘Baodamai 25’is the best,followed by‘Baodamai 8’and‘Baodamai 14’,and‘Baodamai 15’is less suitable for planting in Boshan.
