摘    要:探讨了不同生长年限对青海草地早熟禾人工草地生长特性和种子产量及构成因子的影响,为青海草地早熟禾种子生产提供理论依据。结果发现,随着人工草地生长年限的延长,生殖枝高度、营养枝高度以及花序长度总体上都呈降低的趋势。不同的生长年限对青海草地早熟禾种子产量及其构成因子的影响表现在:2龄人工草地的种子产量最高,达到496.96k...

关 键 词:青海草地早熟禾  生长年限  种子产量  产量构成因子

Abstract:Effects of different growth years on growth characteristic,seed yield and yield component factors of P.pratensis L.cv.Qinghai were studied to provide theory basis for P.pratensis L.cv.Qinghai seed production.The results indicated that the fertile tillers height,the sterile tillers height and the inflorescence length of P.pratensis L.cv.Qinghai would gradually decreased with passage of planning time of artificial grassland.The effect of different growth years on seed yield and yield component factors of P.pr...
Keywords:Poa  pratensis  cv  Qinghai  Growth years  Seed yield  Yield component factors
