摘要
2001年,在四川甘孜州13个县开展了优良牧草——高丹草的适应性研究。结果表明,高丹草在海拔3 000 m以下的农区适宜生长,每667m2最高鲜草产量可达4 334 kg;在海拔3 000-3 500 m 半农半牧区生长势差;在海拔3 500-4 000 m地区生长势更差;而在海拔4 000 m以上则不能正常生长。
In 2001, Gaodan grass was planted in 13 counties of Ganzi District of Sichuan province. We
found that Gaodan grass can grow well in the agricultural district with altitude lower than 3000 meter. The
highest yield reached 4334kg/666.7m2. It grew bad at the agricultural and pasturing area with the altitude of
3000- 3500 meter. It grew worst at the altitude of 3500-4000 meter. It cannot grow normally at the altitude
higher than 4000 meter.
