摘　　要：为筛选出适合重庆市种植的高产高粱属饲草品种,笔者于2016年开展了6个不同高粱属饲草品种的对比种植试验。结果表明:参试的6个高粱属饲草品种第一茬公顷鲜草产量均在55.8吨以上,第二茬平均公顷鲜草产量均在54.0吨以上,全年公顷鲜草产量均在109.65吨以上,综合试验结果,饲用甜高粱-美洲巨人和海牛、高丹草-光明星3个品种在重庆市种植可获得较高的产量,可作为重庆市高产高粱属饲草推广种植的备选品种。In order to screen the high-volume varieties of Sorghum forages which were suitable for planting in Chongqing,six varieties test of Sorghum forage were planted in Chongqing in 2016.The results showed that the yield of fresh grass per hectare of the six Sorghum forage varieties tested was over 55.8 tons in the first crop,over 54.0 tons in the second crop,and over 109.65 tons in the whole year.The comprehensive test results and analysis indicated that three varieties of Sorghum forage can get high yield of fresh grass in Chongqing,they were two varities of feeding sweet Sorghum:American Giant and Sea Cow,and one variety of Sorghum×sudangrass:Guang Mingxing.The three varieties of Sorghum forage can be used as high-volume varieties in Chongqing by repeated experiments in the future.
