Abstract为了探究不同播种密度对青海省不同海拔生态区3个饲用小黑麦品系群体动态、灌浆期株高和草产量、收获期草产量等生产性能的影响,本试验设3个播种密度(3.00×10~6株/hm~2, 3.75×10~6株/hm~2, 4.50×10~6株/hm~2),3个不同海拔生态区(乐都生态区, 2 016 m;湟中生态区, 2 630 m;同德生态区, 3 251 m)和3个自育品系(ZHS2, ZHS1, GY197)。对各播种密度下不同生态区3个小黑麦品系的生育期、群体动态、草产量、穗部性状、籽粒产量和经济系数等指标进行测定,并对其差异进行分析。结果表明,种植密度对饲用小黑麦生产性能影响较大,在乐都生态区品系ZHS2的分蘖成穗率、鲜草产量和干草产量、籽粒成熟期干草重、籽粒产量和经济系数等指标在播种密度为4.50×10~6株/hm~2时达最大值;湟中生态区,品系ZHS2的分蘖成穗率、鲜草产量和干草产量、籽粒产量等指标在播种密度为4.50×10~6株/hm~2时最大;同德生态区,自育品系ZHS2的田间出苗率、鲜草产量和干草产量在播种密度为4.50×10~6株/hm~2时最大。结合TOPSIS综合分析结果可得,在各生态区,品系ZHS2的播种密度为4.50×10~6株/hm~2时,综合生产性能最佳。本研究可为青海农牧交错区小黑麦高效栽培技术探究提供理论依据。
