| 摘 要： | 研究施肥量和播种量对当年播种的多叶老芒麦叶面积增长和干物质积累的影响.结果表明,当年播种的多叶老芒麦能完成全部生育期,种子能够成熟;施肥量对多叶老芒麦叶面积增长和干物质积累的影响极显著,且以N-P-K为60-30-30(均为有效成分,kg/hm2)最为理想;不同播种量对叶面积增长和干物质积累在种子成熟以前贡献很大.

| Abstract: | Effects of fertilizing and sowing amounts on the growth of leaf area(LA) and the accumulation of dry matter(md) of Elymus sibirlius L.cv.Duoye were studied.The results showed that the Elymus sibirlius L.cv.sowed in that very year ccould complete the whole growth duration with maturation of seeds.The fertilizing amount significantly influenced the growth of leaf area and the accumulation of dry matter of Elymus sibirlius L.cv..The most perfect proportion of N and P and K was 60 and 30 and 30(kg/hm2).Before seeds maturing,different sowing amount greatly contributed to the growth of leaf area and the accumulation of dry matter. |
