摘　　要：经过2年的引种试验,适宜试验区栽培的青贮玉米Zea mays品种有科多4号、科多8号和精饲816,鲜草产量均可达15 000 kg/hm2以上;块根饲用作物以韩国胡萝卜和成都胡萝卜表现最为突出,生物产量可达15 000 kg/hm2以上。引种新品种的产量和经济效益都明显高于目前试验区生产所用的品种,用新品种替代旧品种已势在必行。Through two years study on introducing varieties, many new varieties appropriate for cultivation in the test area have been achieved, for example, in the respect of ensilages, the varieties of silage corn are Keduo No. 4, Keduo No. 8 and concentrate 816, they are ranged prior to others either in production or in economy. Their fresh herbage yield reached to 150 00i3 kg/hm^2; in the respect of tuber forage crops, the Corea carrot variety and ChengDu carrot variety are the most outstanding varieties, their biological production has attained to 150 000 kg/hm^2 or more. The new varieties introduced either in forage production or in economic effects are obviously higher than that of the local species used here at present. Consequently, it is an irresistable tendency that the old varieties would be substituted by new varieties.
