几种高粱属饲料作物的引种试验

An introduction trial of several cultivars of sorghum forage

以11个品种的高粱属牧草为研究对象,于2003年在景泰县草窝滩乡(代表绿洲灌区)对其进行了物候期、鲜草产量、干草产量、种子产量研究,结果表明:干草产量以甘露BMR最高,为42358.46kg/hm2,其次为瑞奥3号和意大利,分别为35516.16kg/hm2和33709.41kg/hm2;种子产量以瑞奥3号最高,为9753.30kg/hm2,其次为丽欧9202.60kg/hm2和海牛9160.58kg/hm2。研究表明在景泰地区,最适宜利用的是高丹草,最好的品种是甘露BMR,其次为瑞奥3号、意大利和丽欧。

The phenology period, fresh yield, hay yield and seed yield of eleven cultivars of sorghum forage were studied at Caowo Village in Jingtai County (oasis irrigating area) in 2003. The results showed that Ganlu BMR (42 358.46 kg/hm2) was the highest in hay yield, the following two cultivars were Ruiao No.3 (35 516.16 kg/hm2) and Italy (33 709.41 kg/hm2). Ruiao No.3 (9 753.30 kg/hm2) had the highest seed yield, the following two cultivars were Liou (9 202.60 kg/hm2) and Hainiu (9 160.58 kg/hm2). Gaodan grass was the most suitable species to be utilized in Jingtai. The best adaptive cultivar was Ganlu BMR and the better cultivars were Ruiao No.3, Italy and Liou.
