黄瓜群体叶面积无破坏性速测方法研究

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。

Studies on A Quick Intact Measurement to Cucumber Colony's Leaf Area

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 thatthere is no rema rkable difference between the measured leaf area and the real leaf area of nine v...
