摘要(Abstract)：
采用5因子5水平正交旋转回归组合设计方法,以不同浓度的硼砂、GA3、尿素、NAA、2,4-D配成36个处理,在梨枣幼果发育期对植株全量喷洒,探讨防止果实脱落、提高结果指数的最佳药剂和不同药剂的最佳配比与浓度。结果表明,不同药剂对提高山西梨枣结果指数效应的作用程度大小依次为:尿素>NAA>硼砂>2,4-D>GA3。混合药剂中双因子互作提高山西梨枣结果指数效应最大的是硼砂和GA3,其次为硼砂和NAA。在结果指数90%以上的预期目标下,混合药剂中不同成分的使用浓度模拟结果为硼砂0.1558%～0.1700%,GA315.58～16.09mg/L,尿素0.1210%～0.1313%,NAA15.07～16.57mg/L,2,4-D7.916～8.571mg/L。
