摘　　要："川中"鹅观草(Roegneria kamoji cv.Chuanzhong)是四川农业大学小麦研究所选育的国审牧草新品种。该品种多年生、耐贫瘠、蛋白含量高(达24.6%),可作为山地、丘陵等中低海拔地区种植的优良牧草。为探明"川中"鹅观草在成都平原的最佳高产栽培技术,采用单因素处理方法设计不同播种量、行距、刈割后追肥量、播种时间及与其他牧草混播比例等栽培因素,探讨"川中"鹅观草最佳栽培模式。试验结果表明:当"川中"鹅观草以种子用量3g/m^2,行距30cm,刈割后追肥20g/m^2,并在10月中旬播种的栽培模式时,能发挥最大的产草性能。"川中"鹅观草与不同牧草品种混播的草产量都高于鹅观草单一播种,且与多花黑麦草1∶1混播模式产量最高,实际生产中可大力推广。Roegneria kamoji cv. Chuanzhong is a new variety breed by Triticeae Research Institute,Sichuan Agricultural University.The variety is perennial with high protein content（ 24. 6%）,and is resistant to sterile. In order to establish the management strategies for high forage yields of R. kamoji cv. Chuanzhong in Chengdu plain,we use single factor processing method in different sowing quantity,line spacing,fertilizer,sowing time and mixed with other pasture with different ratio. The results showed that the best cultivation pattern was3 g/m^2 sowing rate,20 g/m^2 fertilizer rate,30 cm line spacing and sowing in the middle of October. R. kamoji cv. Chuanzhong and Lolium multiflorum sowed at the ratio of 1 ∶ 1 was the best mixed.
