摘要:
对不同施肥期4种多年生禾本科牧草生长特性和种子产量进行了研究, 结果表明:不同施肥期4 种牧草生育期变化不大;羊草和扁穗冰草在抽穗期施肥株高最高, 无芒雀麦拔节期施肥株高最高, 比对照高 14.9 cm, 施肥处理降低垂穗鹅观草的生长速度;返青期施肥羊草、垂穗鹅观草和扁穗冰草的产量最高, 无芒雀麦在抽穗期施肥后牧草产量和质量最高, 茎叶比为0.62;羊草在拔节期施肥种子产量、发芽率显著高于对照, 垂穗鹅观草和扁穗冰草在返青期施肥种子产量、质量均高于对照和其它施肥期。
Abstract:
The growth characteristics and seed yield of four forages in different fertilization periodwere studied in this paper.The results showed that:Growth period have no change weather fertilized or not.The plant height of Leymus chinensis(Trin .)Tzvel and Agropyroncristatum(L. )Gaertn which fertilized in tassel stage and jointing stage for BromusinermisLeyss were the highest, which 14.9 cm higher than that of the control.Fertilization reduced growth speed of Roegnerianu-tans Keng.The biomass yields of Leymuschinensis(Trin.)Tzvel, Roegneria nutans Keng and Agropyron cristatum(L.)Gaertn were largest when fertilized in re-greening stage period, Bromusinermis Leyss had largest biomass yield and qualityafter fertilizedinheading stage.Fertilization couldimprove seedyield.The seed yield and germination rate of Leymuschinen-sis(Trin.)fertilized in jointing stage was significantly higher than the control, and the ratio of stalk to leaf was 0.62.Tzvel,Roegneria nutans Keng and Agropyroncristatum(L.)Gaertnhave highest seed yield and quality thanother fertilization pe-riod and the control when fertilized in heading stage.
