在油茶的生产和科研活动中,常需测定油茶叶面积这个丰产栽培和生物学特性指标。目前国内外测定叶面积的方法很多,运用于测定油茶呈面积时各有利弊和局限性。现介绍一种叶模扳测定油茶叶面积的方法。一、设计原理:据一些研究成果报导和笔者观察,我国南方分布较广的普通柚茶(Camellia Oleifera)和小果油茶(Camellia meocarpa),其叶片植物学特征有一定的稳定性,同一性在不同栽培条件下叶片面积大小有不同,但叶型在不同地区或子代变异性不显著,其叶片长和宽的限值、叶形指数(叶长/叶宽)、叶面积系数(叶长×叶宽/用求积仪测出的叶面积)在一定范围内都有近似定值。据此,就有可能按照不同叶型制作出几套叶模型,每套含几何
In the production of tea and scientific research activities, often need to determine the leaf area of oil and tea cultivation and biological characteristics of this index. At present, there are many methods to determine the leaf area at home and abroad, and each method has its advantages and disadvantages and its limitations when used to determine the area of camellia. Now introduce a leaf pull template to determine the area of tea leaf method. First, the design principles: According to some reports of research reports and the author observed that the broad southern China widespread common Camellia Oleifera and Camellia meocarpa, Camellia meocarpa leaf has a certain degree of botanic stability, identity in the The leaf area varied under different cultivation conditions, but the leaf types did not show significant variability in different regions or offspring. The leaf length and width limits, leaf index (leaf length / leaf width), leaf area index × leaf width / leaf area measured with a sigma) have approximate values within a certain range. As a result, it is possible to produce sets of leaf models in different leaf shapes, each with a geometry
