摘要
采用单因素随机区组设计 ,研究了春季不同时期施肥对多年生黑麦草 (LoliumperenneL .)种子生产性能的影响。结果表明 :春季不同时期施肥处理间差异极显著 (P <0 .0 1) ,以返青期和分蘖至拔节期施肥的种子产量最高 (平均达到 715 .2kg/hm2 )。因此 。
The Seed productivity of turf-type perennial ryegrass(Lolium perenne L.)with fertilization at different stages in Spring were studied with the single-factor random block design. It was indicated that there were extrecmely significant difference in seed yield among the different treatments (P<0.01) and the seed yield for fertilizing ranked the highest with 715.2kg/hm 2 at green-turning stage or tiller-elongating staeg. Therefore, fertilization at green-turning staege or tiller elongating stage was the best way to increase seed yield of perennial ryegrass.
