蔬菜作物叶面积的活体测算方法的研究

本研究对几种蔬菜作物的叶长、叶宽、叶长×宽与实际叶面积的相关关系作了进一步探讨。长辣椒[Var·langum Bailey]、菜豆(P·Vulgaris L.)和甜瓜[Cucumis melo,L.]的叶片形状整齐,对其叶长×叶宽之积和叶长+宽之和与实际叶面积的相关关系进行了测算。众所周知,活体叶面积的测算是生产和科研所必须的,相关法是通常应用的有效方法,我们将系数法应用于某些蔬菜活体叶面积的测算,结果表明系数法比相关法更简捷、方便、结果可靠

Studies on Measurements of Living Leaf Surface Vegetables

In this paper, the authors make a further investigation on the correlation between the length, width and the lenth×width of leaves and the actual surface of the leaves. The leaves of Vat. langum Bailey, P. vulgaris L., and Cueumis melo L. are more or less uniform. Measurements have been made in order to get the correlation between their leaf lenth×width and length+width, and the actual Surface of the leaves, It is well-known that the living leaf surface measurements are essential in production and scientific research. The effective method frequently used for this :purpose is thought to be correlation method. We have adapted the coefficient met hod in living leaf surface measurements. It has proved that it is much simpler, more convenient and reliable than the correlation method.
