摘  要:
在海南省东方县半干旱条件下,对5种臂形草属牧草(Brachiariaspp.)进行3a区域性品比试验,结果表明,产量最高的是杂交臂形草(B.hybridCIAT9201/1873)和网脉臂形草(B.dictyoneuraCIAT6133),年干草产量分别达到18938和16869kg/hm2,分别比对照热研6号珊状臂形草(B.brizanthacv.ReyanNo.6,年干草产量12694kg/hm2)增产49.2%和32.9%。其中杂交臂形草是株丛型草,可用作刈割型饲料;网脉臂形草由于草质硬,生长速度快、草层密度大、耐践踏,耐酸性瘦土,特别适合用作人工草地和覆盖用草;刚果臂形草茎叶柔软而毛少,适口性较好,是饲养幼畜幼禽的优良品种。

摘  要:
Comparison test of Five Brachiaria spp. accessions on semiarid condition in consecutive threeyears in Dongfang County, Hainan Province was conducted. The result showed that Brachiaria hybridCIAT9201/1873 and B. dictyoneura CIAT6133 gave the highest yields. Dry grass yields of them reachedto 18 938 kg/ha and 16 869 kg/ha respectively per year, increased by 49.2% and 32.9% comparing to CK(B. brizantha cv. Reyan No.6). B. hybrid was suitable for cutting forage because it is cluster; B.dictyoneura CIAT6133 served as artificial pasture and mulsh owing to possessing trampling-resistance andthe ability of rapid growth; B. ruziziensis CIAT6095 is superior forage for pup and poultry because of itssoft stem and leave, few fur, and good palatability.
