摘要:

为了研究不同棱型大麦品种混种及其混种组合对大麦饲草产量的影响,以二棱矮秆品种‘保啤麦26号’、‘保啤麦28号’和多棱中高秆品种‘保大麦20号’、‘保大麦25号’为材料,设8个处理,进行单种和混种比较试验。结果表明:单种处理中,从鲜草产量来看,‘保大麦25号’与‘保啤麦28号’间不显著,但显著高于‘保啤麦26号’、‘保大麦20号’,二棱品种‘保啤麦28号’与多棱品种‘保大麦25号’、‘保大麦20号’两个混种组合的鲜草产量较高,分别为41.36 t/hm2、39.19 t/hm2,比单种‘保啤麦28号’增产14.14%、8.14%,比单种‘保大麦25号’增产9.38%、3.63%;4个混种处理,有效茎数比单种多棱品种处理增加61.95~219.90万/hm2;单茎鲜重、穗实粒数分别比单种二棱处理增加0.06~1.12 g、4.3~6.5粒;混种处理能有效减轻倒伏和降低白粉病级数。综上,大麦二棱矮秆品种与多棱高秆品种混种时,只要品种选择合适,混种的鲜草产量显著高于单种鲜草产量,二棱品种宜选择‘保啤麦28号’,多棱品种宜选择‘保大麦25号’。研究以期为饲草的农业生产提供一定的参考。

Abstract:

To study the effects of mixed planting of barley varieties with different edge types and their combinations on forage yield, field experiments were conducted with four barley cultivars: two-rowed short-statured ‘Baopimai 26’ and ‘Baopimai 28’, and six-rowed medium-tall ‘Baodamai 20’ and ‘Baodamai 25’. Eight treatments were designed for both single planting and mixed planting comparative experiments. The results showed that, in single planting experiment, there was no significant difference in fresh grass yield between ‘Baodamai 25’ and ‘Baopimai 28’, which were significantly higher than those of ‘Baopimai 26’ and ‘Baodamai 20’. In mixed planting experiment, the combinations of the two-rowed cultivar ‘Baopimai 28’ and the six-rowed cultivars ‘Baodamai 25’ and ‘Baodamai 20’ produced the highest fresh forage yields, reaching 41.36 t/hm² and 31.19 t/hm², respectively. Compared with single planting of ‘Baopimai 28’, these mixed planting increased yields by 8.14% and 14.14%, respectively, and compared with single planting of ‘Baodamai 25’, they increased yields by 3.63% and 9.38%, respectively. Thus it is not recommended to mix the two-rowed cultivar ‘Baopimai 26’ with other cultivars. Moreover, the six-rowed cultivar ‘Baodamai 25’ performed better than ‘Baodamai 20’ in mixed cultivation.
