摘要
分施肥和不施肥两组比较分析了早春施肥对东非狼尾草生长的影响。结果表明:早春施肥促进东非狼尾草生长,主要原因是叶面积、叶绿素含量、光合强度显著增加,生长速率提高;早春施肥对东非狼尾草光合产物分配、净同化率影响较小。
The study,divided into two groups:fertilizing in early Spring and non-fertilizing,was carried out for analyzing the effects of fertilizing on growth of Kikuyu grass.The result showed that the fertilizing in early Spring promoted the growth of Kikuyu grass,which due to the increases of leaf area,chlorophyll content,photosynthetic rste and growth rate.But,fertilizing in early spring did rarely affect to the assignment of photosynthetic products and net assimilation rate(NAR).
