本试验为鄂西山区草地建设项目准备工作的一部分。为了筛选出人工草地建植中所需优良禾本科草种,我们从1982年开始引进苇状羊茅。在不同海拔高程的3个点试种,继而在低山、丘陵大面积应用。据观察苇状羊茅产草量高。能抗夏季高温干旱;耐放牧,再生性好;竞争力强,在豆、禾混播草地能长期保持稳定的比例。为目前低山丘陵地带引种材料中适应性最好的禾本科牧草。该草在我区中高山还需进一步试验观察。
This experiment is part of the preparatory work for grassland construction in western Hubei mountainous area. In order to screen out the fine grass species needed for artificial grassland construction, we started to introduce tall fescue from 1982. At three different elevation points of the test species, followed by low mountains, hills, large area applications. It is observed that tall fescue yield grass. Resistant to high temperature and drought in summer; good resistance to grazing and regeneration; strong competitiveness, and long-term stable ratio of beans, grasses and grasslands. For the current hilly areas introduced the most adaptable materials of grasses. The grass in my area in the mountains need further experimental observation.
