摘要
研究了不同施肥时期及施肥量对草地早熟禾生长发育特性的影响。研究表明:返青期加强施肥有利于草地早熟禾的生长,同时,可显著提高植株密度以及干物质的积累量。
The effects of fertilizer on growth and development characteristics of Poa pratensis at different application time and rate were studied. The results indicateded that the height, density and yield could be significantly increased when fertilizer was applied in returning green stage.
