草田小气候效应初探

A DISCUSSION ON THE EFFECT OF MICROCLIMATE ON GRASS AND BARE LAND

为了研究光、热、气、水对牧草生长发育的影响,探讨牧草生育对外界环境条件的适应性和统一性,本文以红豆草的草田小气候观测资料为依据,分析了太阳辐射在草田中随植株高度而变化的分布规律;研究了草田温度在不同时段呈“受热型”和“放热型”等的独特变化特征和草田空气温度比祼地高、变化差异小等特殊小气候。

In order to study the effect of external condition on the development and growth of holy clover, approach the adaption of holy colver to environment, based on microclimatical observations of holy clover, analysed the changes of solar radiation with height of the plant and found out that thcrc are two types of the plant i. e. collective hot and release hot during different growth season of thc plant and different microclimate between the grass and bare land.
