不同灌溉条件下燕麦籽粒植酸、总磷、蛋白质及矿质元素含量变化特征研究

采用防雨池栽方法研究了不同灌溉条件下两种栽培类型燕麦白燕7号皮燕麦（Avena sativa L.）和内农大莜一号裸燕麦（Avena nuda L.）籽粒植酸、总磷、蛋白质、钙、镁、钾、锌、铁、铜、锰含量变化特征。随灌水次数和灌水量的增加，内农大莜一号裸燕麦籽粒总磷和铜含量呈线性变化，籽粒产量、植酸、钙、镁、钾、锌、锰含量变化呈二次函数；白燕7号皮燕麦籽粒（去壳）锌和铁含量呈线性变化，植酸、总磷、粗蛋白、钙、镁含量呈二次函数变化。

Studies on the Change Characters of Grain Phytic Acid, Total Phosphorus, Protein and Minerals Contents in two Oat Varieties under different Irrigation Conditions

The change characters in concentrations of phytic acid, total phosphorus, crude protein, Ca, Mg, K, Zn, Fe, Cu, Mn in grains of two oat varieties grown different irrigated conditions were studied in proof-rainfall-canopy. The changes in grain total phosphorus and copper contents with the increase of irrigation times and quota were linear while those of phytic acid, Ca, Mg, K, Zn, Mn were quadratic in Neinongda No.1 naked oat. The changes of Baiyan No.7 hull oat in garin (husked) Zn and Fe content with the increase of irrigation times and quota was linear while those of phytic acid, total, crude protein, Ca and Mg contents were quadratic.
