摘要
在防雨池栽条件下,研究了不同灌水时期、灌水次数和灌水量对两个不同类型燕麦品种内农大莜1号(AvenanudaL.)和白燕7号(A.sativaL.)籽粒产量及营养品质性状的影响。结果表明,内农大莜1号籽粒粗蛋白、总磷、钙、镁、锌、铁(P<0.01)和钾含量(P<0.05)高于白燕7号。不同灌水制度对植酸、总磷、蛋白质、钙、镁、钾、锌、铁和铜含量有显著影响,全生育期灌水3次(底墒+拔节水+抽穗水),灌水量1 800 m3hm-2;或灌水4次(底墒+分蘖水+拔节水+抽穗水),灌水量2 400 m3hm-2有利于燕麦籽粒产量和大多数品质性状的提高。大多数品质性状存在显著的品种×灌水互作效应。不同营养品质性状随灌水量变化规律不一致,并存在基因型差异。
