印度落芒草引种栽培试验初报

The Primary Study on Growth of Introduced Indian Ricegrass

对从美国引进的印度落芒草在内蒙古呼和浩特的产量、营养动态、生物学特性进行了研究,结果表明:印度落芒草具有返青早、枯黄迟、青绿期长、分蘖力强、叶量较丰富、抗性强、利用价值高等优点;从产量和营养动态来看,印度落芒草的最佳利用时期是开花期;常规管理条件下印度落芒草能较好的适应呼和浩特地区的土壤及气候条件,可在我国北方半干旱地区作为优良牧草和生态建设草种推广应用。

Indian ricegrass Was introduced from America,its performance was observed in Hohhot in 4 successive years,its yield dynamics,nutrition dynamics and biological characteristics were studied and analyzed. The results indicated that Indian ricegrass turned green early, and withered late, had a long green period, strong tillering ability, abundant leave, good resistance and grand utilization value;The yield and nutrition dynamics of Indian ricegrass revealed that the optimal utilization period was flowering stage; It could adapt to the soil and climate condition in Hohhot very well, could be widely cultivated as excellent forage and ecological construction grass in semi-arid area of northern China.
