苇状羊茅91-82新品系品比试验报告

Comparision Between the New Fescue Strain 91-82 with Fescue Fawn

选育出的苇状羊茅91-82新品系跟生产上推广种植的进口草种法恩(Fawn)相比,表现出植株高大,生长迅速,最高生长速度可达2.458 cm/d。整个生育期内,其植株高度均明显高于法恩,最高可达155cm,较对照高32.5cm;产草量高,每667m2年产干草可达1 436.77-1 851.67kg,比对照品种法恩(896.82-1 207.22kg)增产53.38％-60.21％,表现出显著的栽培利用价值。结果表明,苇状羊茅91-82是贵州省中南部地区人工草地建植的理想禾本科牧草新品种。

In this study, we compared the production characteristics of Fescue91-82, which was newly crossbred from different Fescue strains, with Fescue (Fawn) which was introduced from overseas and widely expanded in production. We found that the growth velocity of Fescue91-82, with 2.458cm/d, was faster than that of Fescue (fawn). During the whole growth period, Fescue 91-82 was significantly higher than Fawn, 155cm versus 122.5cm.The dry matter of Fescue 91-82 was 1436.77-1851.67kg /mu, 53.38%-60.21% higher than Fawn. In conclusion, Fescue 91-82 was better than Fawn for artificial grassland in the middle south district of Guizhou.
