摘要
在山西晋中地区对长江2号、邦德、特高、海湾、安哥斯5个多花黑麦草品种进行不同播种量(高22.5 kg/hm2,中15 kg/hm2和低7.5 kg/hm2)试验,结果表明:5个多花黑麦草品种均能在山西省晋中地区完成的生育期,干草产量以中等播种量的邦德产量最高。5个品种干草量由低到高依次为:邦德<海湾<特高<安哥斯<长江2号,3个播种量条件下的干草产量依次为:低播种量<高播种量<中播种量。
The performance of five Italian ryegrass cultivars (Abundant, Gulf, Tetragold, Angus and Changjiang No. 2) with 3 seeding rates (22.5 kg/hm^2 15 kg/hm^2 and 7.5 kg/hm^2) was studied in Jinzhong, Shanxi Province. The results showed that all of the five cultivars could grow well in the whole growth period. The dry matter yield reached the maximum peak under 15 kg/hm^2 of seeding rate for all tested cultivars. In which,Abundant got the highest yield. The order of yield was Abundant 〈 Gulf 〈 Tetragold 〈 Angus 〈Changjiang No. 2,and the order of yield at different sowing rates was low〈high〈medium.
