摘 要:
对在广东地区引种的国外20个优良多花黑麦草（Lolium multiflorum L．）品种的产量和品质等进行了分析．结果表明，刈割3茬的鲜草中，第2茬的产量最高，与总产量存在极显著正相关（P〈0．01）．各品种间前3茬鲜草产量、绝对干物质产量存在显著差异；所有品种绝对干物质率为8．4％-12．7％，其中各品种间前3茬刈割的干物质率存在极显著差异（P〈0．01）．品种01-Lm-1、LMT 1107、Common 1、Archie和LWD 8181—2的鲜草产量较高，达10．17kg／m^2以上，品种01-h-1、LWD 8181—2、BAR 9TAM、Barprisma和LMT 9034的绝对干物质产量较高，达1．01kg／m^2以上．平均粗蛋白含量在16．05％～24．56％之间，品种间有极显著差异（P〈0．01），其中品种Conamon 1、LWD 8115、LWT 8140的粗蛋白含量达23．52％以上．[著者文摘]

Abstract:
20 varieties of annual ryegrass （Lolium multiflorum L. ） were cultured and investigated from November 2003 to May 2004 in Guangdong area. The results showed that the yield of fresh grass of all the tested varieties at the second cutting time was the highest, and they were significantly correlated with their total yield. However, the total green yield and the dry matter of the varieties for the three cutting times were significantly different. The dry matter of all varieties was varied from 8.4% to 12.7%, and the dry matter of the varieties for the first three cutting time were highly significantly different （P 〈 0.01）. The fresh yield of 5 varieties 01-Lm-1, LMT 1107, Common 1, Archie and LWD 8181-2 for 3 cutting times were significantly higher, which was more than 10.17 kg/m^2, and the dry matter of 5 varieties 01-Lm-1, LWD 8181-2, BAR 9 TAM, Barprisma and LMT 9034 were significantly higher, which was more than 1.01 kg/m^2. The average percentage of crude protein content of them was from 16.05% to 24.56%, and the difference was highly significant （P 〈 0.01）. The percentage of crude protein content of Common 1, LWD 8115 and LWT 8140 was more than 23.52%.[著者文摘]
