摘　　要：以津优1号和津春4号黄瓜品种叶片为材料，以实际叶面积、叶长、叶宽、肩宽和肩高为测算指标，以成对分析法作统计检验，经计算机择优筛选，获得黄瓜叶面积活体快速估测的一种新方法──等腰三角形法。1999～2000年笔者对此方法的有效性和通用性进行了验证，结果表明：被估测的9个品种(或组合)的叶面积与实际叶面积间均无显著差异。实际应用中，只需测量出叶长，便可简单地估算出叶面积，实现了黄瓜叶面积活体快速估测。Cucumber varieties ‘Jinyou No.1’ and ‘Jinchun No.4 ’ were selected as experimental material，Cucumber leaf area，leaf length，leaf width，leaf shoulder height and width were set as measuring index. A n ew method - isosceles-triangle method to quick measurement of cucumber lea f area was developed through statistics dilemma analysing and computer optimum sifting. It was tested in 1999-2000，the result showed that：there is no rema rkable difference between the measured leaf area and the real leaf area of nine varieties of cucumber. The cucumber leaf area can be estimate easily by only measuring the leaf length. Therefore，it is a true quick intact mea surement of cucumber leaf area.
