【摘要】 在河北省黑龙港地区选择深州市护驾迟、威县赵村和沧县前营3个试验点,对14个青贮玉米品种的生育期、农艺性状、抗逆性、生物产量和饲用品质等指标进行综合评定,旨在筛选出晚春播条件下适宜和饲用小黑麦搭配种植的青贮玉米品种,为该地区"粮改饲"及草牧业发展提供技术支撑。结果表明:北农青贮2932、北农青贮208和辽单青贮625与饲用小黑麦搭配种植较好。3个品种生物产量均超过1 300kg/hm~2,一致表现为抗病、抗倒,生长期适中、叶量丰富、饲用品质优,适宜在黑龙港地区晚春播条件下和饲用小黑麦复种,形成饲用小黑麦-青贮玉米复种模式。更多还原

【Abstract】 The growing stages,agronomic traits,stress resistance,biological yield and forage quality of 14 silage corn varieties,produced at three experimental sites in Heilonggang area of Hebei province,were comprehensively analyzed.The aim of this study is to screen a suitable silage maize variety for the forage triticale-silage maize cropping system sown in late spring,and to provide technical support for livestock husbandry development.The results revealed that Beinong 2 932,Beinong 208 and Liaodan 625 were the most suitable silage maize varieties.The average biological yields of the three varieties were above 1 300kg/ha.The three varieties exhibited good traits quality in disease resistance,lodging resistance,medium growing period,abundant leaves and high forage quality.The three varieties were suitable maize varieties for the forage triticale-silage maize cropping system.更多还原
