Don) stand in an experimental field on the Nagoya University Campus. The nutrient amount in the litterfall was analyzed. Total litterfall was 934g m^-2 per year. Leaves, branches, fruits and flowers contributed 80.35, 7.48, 4.38 and 7.79%, respectively, to the total litterfall. Litterfall, which was the highest in September, was attributed to the effect of a typhoon. The total amount of nutrients in the litterfall was 29.04 gm^-2 per year. The relative amount of the nutrients was in the order Ca\u003eN\u003eK\u003eP\u003eMg. Calcium, accounted for 60.50%, N 27.73%, K 10.74%, P2.38% and Mg 2.34% of the total. The nutrient amounts in the litterfall was significantly correlated with the litterfall mass. Nutrient concentrations of the litterfall showed seasonal variations. A high nutrient efficiently uses Mg which indicates that Mg is in a limited supply.

内容記述 | Litterfall was collected at monthly intervals over a one-year period in a Japanese cedar (Cryptomeria japonica D. Don) stand in an experimental field on the Nagoya University Campus. The nutrient amount in the litterfall was analyzed. Total litterfall was 934g m^-2 per year. Leaves, branches, fruits and flowers contributed 80.35, 7.48, 4.38 and 7.79%, respectively, to the total litterfall. Litterfall, which was the highest in September, was attributed to the effect of a typhoon. The total amount of nutrients in the litterfall was 29.04 gm^-2 per year. The relative amount of the nutrients was in the order Ca>N>K>P>Mg. Calcium, accounted for 60.50%, N 27.73%, K 10.74%, P2.38% and Mg 2.34% of the total. The nutrient amounts in the litterfall was significantly correlated with the litterfall mass. Nutrient concentrations of the litterfall showed seasonal variations. A high nutrient efficiently uses Mg which indicates that Mg is in a limited supply. 名古屋大学構内の13年生スギ林のリターフォール速度および養分含有率の季節的変化を調べた。一ヵ年のリターフォール量は934gm^-2、そのうち葉、枝、果実、花はそれぞれ全リターの80.35、7.48、4.38、7.79%を占めた。9月に台風によるリターフォールのピークがあった。1年間のリターの養分量は29.04gm^-2、この中カルシウム60.50、窒素27.73、カリウム10.74、リン2.38、マグネシウム2.34%であった。リターフォール量とそれに含まれる養分量にはかなり高い相関があった。養分含有率は季節的に変化した。マグネシウム利用効率は高く、そのことはその供給量が限られていることを示している。 | |||||
