近年来,我们结合试验工作,参考柑桔叶面积查表法,进行了黄瓜叶面积的大量测定,找出一种黄瓜叶面积快速、准确的测定法——查表法。材料与方法供试品种:津研2号(中熟,叶中大)、长春密刺(早熟、叶较大)、陕早黄瓜(极早熟、叶较小)。生长中后期在各品种中进行随机连续取样5株,然后将每株叶片自下而上全部取下(顶部未展开之小叶除外),共计取叶258片,分别编号,用方格法量出叶面积作为 In recent years, we combine the experimental work, reference citrus leaf area look-up table method, carried out a large number of cucumber leaf area determination, to find a quick and accurate cucumber leaf area determination method - look-up table method. MATERIALS AND METHODS Test varieties: Jinyan 2 (medium ripe, Yezhongda), Changchun dense thorns (early maturity, large leaves), Shaanxi early cucumber (very early maturing, leaves smaller). In the middle and late growing stages, 5 plants were randomly sampled in succession, and each leaf was removed from the bottom up (except for the undeveloped leaflets at the top), a total of 258 leaves were taken and numbered separately. Leaf area as
