摘要
供试 13个多年生黑麦草 (Loliumperenne)品种Napoleon、Thetramax、Mikado、Juventus、Pimpernel、Simberia、Burton、Tonga、Taya、Figaro、Sakini、Tivolia、Pick wick均适宜在宁夏引黄灌区种植。各品种分别于花后 2 1.2— 2 8.6d小穗干物质重达最大 ,小穗含水量为 38.3— 44.8%。此时收获的种子发芽率已基本稳定 ,种子落粒少产量高。供试品种第一年种子产量Taya最高 12 6 1.8kg/hm2 。Figaro、Sakini次之。Juventus产量最低为 5 2 4.1kg/hm2 。
The turf type ryegrass (Lolium perence) varieties, Napoleon, Thetramax, Mikado, Juventus, Pimpernel, Simberia, Burton, Tonga, Taya, Figaro, Sakini, Tivolia, Pickwick, are appropliate planting in the irrigation area of Ningxia. The spiklet dry matter (DM) of every variety is the highest after 21.2——28.6 days following anthesis and the water content per spiklet are 38.3——44.8%, while the seed germination percentage are stable. Taya seed yields of first year are the highest of all, 1261.8/h, Figaro and Sakini are higher than others. Juventus is the lowest of all, 524.1/h.
