植物呼吸分构成、维持二要素,从生长理论(式)推导出密度效果的新理论(式),它论述了原来C—D 的逆数式的有用性。为探讨参数—维持呼吸率(m)和转形效率(YG)的特性而导出的二、三种理论(式),使以前报告的杉木林的生产力解析资料和杉木林分材积表以及树干解析资料的数据适用于各种情况,因而我们多次对m、YG及m·YG 进行了观察鉴定。结果是:虽比农作物的生育期长,但可把m 和YG 大致看成常数。杉木的YG 值是0.38,约是农作物的一半,m 的值约是1/100。虽是从上述不同类
Plant respiration sub-formation, to maintain the two elements, from the growth theory (formula) to derive a new theory of density effect (formula), it discusses the original C-D inverse usefulness. In order to explore two or three kinds of theories (formulas) derived from the parameters of maintaining respiratory rate (m) and transformation efficiency (YG), the previously reported productivity analysis data of Chinese fir plantations and Chinese fir stand volume tables, The data of the data are applicable to various situations, so we have repeatedly observed and identified m, YG and m · YG. The result is that although longer than the crop growth period, m and YG can be roughly considered as constants. The YG value of Chinese fir is 0.38, which is about half that of the crop, and the value of m is about 1/100. Although it is different from the above categories
