摘要： 田间试验结果表明：旱地冬小麦拔节—孕穗期叶面喷施硫酸锌、硫酸锰，或灌浆期喷施磷酸二氢钾均能取得较好效果。叶面喷施磷酸二氢钾能提高千粒重，覆膜N120处理、N240处理小麦分别较其相同氮水平下常规对照提高3.4g和4.3g；提高幅度分别为7.9%和10.4%；但喷施KH2PO4不影响籽粒蛋白质含量。拔节孕穗期叶面喷施锌、锰，具有显著增产效果，较清水对照增产18.4%。

Abstract: (College of Resources and Environment, Northwest A & F University, Yangling, shaanxi 712100) Abtract: Better effects can be made by foliage spraying micro-nutrient (Zn + Mn) from jointing stage to booting stage or KH2PO4 at filling stage. Foliage spraying micro-nutrient (Zn + Mn) from jointing to booting stage increase the production of winter wheat remarkable, relatively higher 18.4% than CK. The thousand grain weight can be raised after foliage spraying at booting stage, but the grain protein content of winter wheat isn’t influenced by KH2PO4.
