一、前言在农田小气候的研究中,我们可以把生长着的农作物的地上部分看作是一个整体,称之为“作物群体”。农作物的群体结构是农田小气候形成的生物学基础,作物生长环境中的光、温、湿、风以及CO_2等要素的分布状况无不与农作物的群体结构状态密切相关。二、作物的群体结构及其组成要素作物群体的几何结构是指农作物地上部分各器官的数量及其空间分布状态。其中,对群体中各器官(如叶、花、茎等)的数量进行描述是比较简单的,对它们的空间状态
I. Preface In the study of cropland microclimates, we can consider the aerial part of the growing crops as a whole and call it a “crop group.” The population structure of crops is the biological basis for the formation of microclimate in farmland. The distribution of light, temperature, moisture, wind and CO 2 in crop growth environment are all closely related to the population structure of crops. Second, the crop population structure and its components Crops geometric structure refers to the aboveground crops of various organs of the number and spatial distribution. Among them, the description of the number of various organs (such as leaves, flowers, stems, etc.) in a group is relatively simple, and their spatial state
