摘　　要：在云南亚热带地区普洱,对3个黑籽雀稗(Paspalum atratum)品种进行引种试验,通过观测抗逆性、生育期、形态特征,测定干草产量、营养价值及灰色关联法综合评价,筛选出最优品种,为人工草地建植提供依据。结果表明:参试3品种适应性强;种植当年CIAT9610干草产量最高,为17.46 t/hm2;热研11号粗蛋白含量最高,为9.26%;热研11号粗蛋白产量最高,为1 472.14 kg/hm2。灰色关联评价表明,热研11号最优,FSP2与CIAT9610次之。The experiment on the comparison of 3 Paspalum atratum varieties in Puer was conducted in Hainan in 2006 for estab- lishing high production and quality pasture. The growth stage, stress resistance, characteristics, the dry yield and nutrient value were studied respectively.The results showed that all the Paspalum atratum varieties could adapt to the condition and be used for the pasture establishment in Puer.In the first year,there was no significance among the trailed forages in terms of the dry matter yield, the crude protein and the crude protein yield.The dry matter yield of CIAT9610 was the highest, reaching to 17.46 t/hm2.The crude protein and the crude protein yield of Reyan 11 were the highest, reaching to 9.26% and 1 472.14 kg/hm2,respectively. By gray system theory to evaluate synthetically forages, Reyan 11 was the top promising species of high yield, good quality, resis- tance performance, high seed yield and high crude protein yield.
