果树叶面积调查方法很多,其中应用单叶面积“S=K×长×宽”这种方法比较简便,这种方法在苹果、梨、桃、杏等树种上应用较多,在草莓上应用还未见报道。草莓叶片为三出复叶,但无论其单叶、复叶都具有一定的几何图形,且比较规则,因此计算叶面积时应用“S=K×长×宽”是可行的。为求得计算草莓叶面积 K 值大小,作了此项调查。调查方法是从大田中随机选取发育正常的叶片,用方格板法求得叶面积,然后量其叶的长宽,所得叶面积与长宽之积比较即得 K 值。草莓叶片为三出复叶,因此可用两种方法估算叶面积,即单叶法和复叶法,现将调查结果总结如下。
There are many ways to investigate the leaf area of fruit trees, among which the method of single leaf area “S = K * L * W ” is relatively simple. This method is applied more on apple, pear, Application has not been reported. Strawberry leaves are three leaves, but regardless of the single leaf, the compound leaf has a certain geometry, and more rules, so the calculation of leaf area, the application of “S = K × L × W” is feasible. To obtain the calculation of strawberry leaf area K value, made this investigation. Survey method is randomly selected from the field of normal development of leaves, with the grid plate method to calculate the leaf area, and then the length and width of the leaves, the resulting leaf area and length of the product that is K value. Strawberry leaves for the three out of the compound, so there are two ways to estimate the leaf area, the single leaf and double leaf method, the findings are summarized below.
