摘要
主要论述了养分回收的概念和意义、衡量参数及其计算方法,比较了养分回收在不同生活型间的差异,分析了养分回收与土壤养分有效性的关系,最后对养分回收的两个参数进行了综合的评价。
In this paper, we maily discussed the concept and significance of nutrient resorption and its measure indices, contrasted the difference of nutrient resorption between growth forms too. We also analysed the relationship between nutrient resorption and soil nutrient availability. In the conclusion, we evaluated synthetically the difference between nutrient resorption-efficiency and nutrient-resorption proficiency.
