摘要
对4个臂形草Brachiaria品种进行3年的生育特性及其品质分析,结果表明,参试品种均可在闽南地区越夏越冬,热研3号和热研6号的开花期均在6月上中旬,杂交臂形草Mulato1与Mulato2开花期比热研6号推迟2个月左右;年均草产量以杂交臂形草Mulato1最高,鲜草产量与热研6号臂形草达极显著水平;营养成分分析结果显示,参试品种分蘖期粗蛋白含量以杂交臂形草Mulato1最高,达9.38%,粗脂肪和钙含量以热研6号最高,相对饲用价值均达100%左右。杂交臂形草Mulato1可作为刈割型牧草在闽南地区推广种植。
The growth characteristic and quality analysis of 4 Brachiaria decurnbens varieties were conducted for 3 years. The results showed that all varieties grew normally in southern Fujian. The blooming stage of Reyan No. 3 and Reyan No. 6 was in the early and middle of June. The blooming stage of 2 hybrid varieties was later about 2 months than Reyan No. 6. The annual fresh yield of Hybrid Mulato 1 was the highest and it was significantly different from that of Reyan No. 6 （P〈0.01）. The crude protein content of Hybrid Mulato 1 was the hightest （9.38%） in tillering stage. The crude fat and calcium contents of Reyan No. 6 were the highest. The relative feeding value of all varieties were around 100%. It suggested that Hybrid Mulato 1 could be widely extended in southern Fujian.
