苇状羊茅在安康地区的生长适应性观察

Observation of Fescue's Growth Adaptability in Ankang Area

[目的]探索苇状羊茅在安康地区适应性。[方法]试验按海拔高度在川道、低山、中山区设立3个试验点,观察物候期,测定植株高度、产草量及耐热性。[结果]苇状羊茅以秋季播种为宜,5月上中旬抽穗扬花,植株平均高度103.4cm,产草量可达56415kg/hm2。苇状羊茅适应性强,即使在冬季也能始终保持青绿,在夏季38℃的高温下生长良好。[结论]苇状羊茅具有耐热、耐旱、生长快、绿期长、易管理等特点,适于在安康地区栽培,是生态建设、发展绿色产业的优良草种。

[Objective] The research aimed to discuss the adaptability of fescue in Ankang area. [Method] Three experiment regions, riverway, low and middle mountain area, were chosen by height above sea level and phonological, plant height, grass output and heat-resistant were observed and measured, respectively. [Result] Seeding in autumn was suitable for fescue. The time for tasseling and blooming was in the first and middle 10 days of May. The average height was 103.4 em, and grass output could reach 56 415 kg/hm^2. The fescue has strong adaptability, and it could hold green in winter and growth well in 38℃ high temperature in summer. [Conclusion] The fescue represented characteristics in heat-resistant, drought -enduring, rapid growth, longtime green and manageable, which was appropriate for Ankang area and was a choiceness grass of zoology - construction and green-industry.
