摘要
本文采用直接收集法收取凋落物,并对凋落物进行详细分类。然后将凋落物各组分定量分装于分解袋中使其自然分解,再按期抽取各样品的分解袋,进行重量测定及营养元素分析,从而得出了凋落物各组分的分解期、半分解期和凋落物在分解过程中营养元素的动态变化规律。
In this paper, the authors gathered the littertall by direct collecting methods, and classified the littertall detailed. Put the component of the litterfall quantitative in decomposition sack, and made is decompose naturaly, than selected the decomposition sack, measured the weight and analysed the nutrient dements, and made the dynamic change regularity of nutrient elements and the period and half-period of componed for litterfall.
