【摘要】 2003~2004年对引种的9种灌木饲用植物的适应性、生产力和经济效益进行研究的结果表明,9种灌木饲用植物在林西县栽培表现出较强的适应性、较高的生产力和经济效益,越冬率达95%以上;生长第二年生育期表现不同,只有尖叶胡枝子、达乌里胡枝子、华北驼绒藜能开花结实完成生育期;产草量决定其经济效益,因牧草种类不同经济效益差异明显。更多还原

【Abstract】 Nine kinds of forage brush cultivars were introduced to Linxi county,which is located at the northern grassland of China,and seeded in experimental plots on the 20th of May,2003.Through two years study,it was found that those 9 forage brush cultivars perfectly adapted to the local dry climate condition in the northern part of Chifen city,possessed high productivity and high economic benefits.Winter survival attended to 95%.During the second year,the performance of them displayed differences in growing period,only the Lespedeza davurica,Lespedeza hedsaroides and Ceratoides arborescens(Losinsk.)Tsien et C.G.can finish the whole growing period,produce more herbage yield and get more economic benefits.更多还原
