为了快速、准确、简便地测算出巨峰系葡萄的叶面积,我们对其叶面积与叶片纵横径的相关性作了一些研究。一、材料与方法供试材料为巨峰、黑奥林、红富士、红伊豆、红蜜、先锋、红瑞宝、高墨、乍娜9个葡萄品种的叶片,树龄均为2年生,每个品种随机采样40片,地点在宋寨葡萄园。分别量出所采叶片纵横径,再用叶面积测定仪测出叶面积,最后求出每个品种纵横径与叶
In order to calculate the leaf area of Jufeng grape quickly, accurately and simply, we made some researches on the correlation between the leaf area and the leaf vertical and horizontal diameter. Materials and methods The test materials for the test materials were Kyoho, Black Olin, Red Fuji, Red Izu, Hongmei, Pioneer, Hongruibao, Gaoju and ZJ. Random sampling of 40 species, located in Songzhai vineyards. Respectively measure the vertical and horizontal blade diameter, and then measure the leaf area of the leaf area measurement, and finally find each variety of vertical and horizontal diameter and leaf
