摘要
为筛选出适应阳江垦区自然环境条件、产量高、品质好的青贮饲料玉米品种,以便于推广应用,该试验通过种植不同品种青贮玉米(东单60、耀青5号、豫青贮23)的大田试验,对比研究其发芽率、生长情况和产量。结果表明:豫青贮23的发芽率最高,耀青5号次之,东单60最低;在生长后期,耀青5号的株高最低,而其叶片数最高;耀青5号的单株鲜重、单株玉米棒鲜重、全株单位面积产量均是最高的,豫青贮23次之,东单60最低。综合来看,相比三种青贮玉米,耀青5号是最适合在本地种植的品种。
In order to facilitate the application of silage maize, and for screening out high yield and good quality variety of silage maize which has good adaptability to the natural environmental conditions of Yangjiang reclamation varieties of area, the germination rate, growth and yield were studied by field trials for planting different silage maize （Dongdan 60, Yaoqing 5, Yuqingzhu 23）. The results showed that： the germination rate of Yuqingzhu 23 was the highest, Dongdan 60 was the lowest and Yaoqing 5 was in the middle; at the later lowest and Yuqingzhu 23 were in the middle. On balance, comparing the three kinds of silage maize, we found that Yaoqing 5 was the most suitable for local planting varieties.
