试验选用5个玉米品种进行夏播种植,通过比较各参试品种的产量及相关植株农艺性状,从中筛选出熟期适宜、高产优质的夏播青贮玉米品种,以期通过搭配种植实现延长青贮玉米收获期,提高青贮玉米产量和青贮品质。试验结果表明:依各品种进入乳熟期日期的早晚,其先后顺序分别为农研青贮1号、北农2275、农大108、富友9号和京科青贮516;进一步对生物产量和植株性状进行分析,富友9号的单株农艺性状表现较好,其鲜质量产量和干物质产量在参试品种中最高,分别为4 875、1 822 kg/667m2。因此,生产中以农研青贮1号搭配富友9号种植较为适宜。
Five maize varieties were selected for summer sowing. By comparing the yield of the tested varieties and the agronomic traits of the related plants, the sowing silage varieties with suitable maturity, high yield and good quality were screened in order to prolong the silage corn harvest Period, to improve silage corn yield and quality. The results showed that: According to the date of entering the milky ripening date, the order of the dates was respectively Nongyan Silaf 1, Beinong 2275, Nongda 108, Fuyou 9 and Jingke Silage 516. The biological yield and plant traits The results showed that the individual agronomic traits of Fuyou 9 performed well, with the highest fresh yield and dry matter yield of 4875 and 1822 kg / 667m2, respectively. Therefore, the production of agricultural research Silage No. 1 with Fuyou 9 planting more appropriate.
