| The dry-matter production, the litter decomposition and the nutrient cycle were studied on Quercus serrata and Carpinus laxiflora forests at Piagol in Mt. Jiri. With the growth curves of the annual ring, the time schedules for the maximum productivities and maximum yields were measured. In Q.serrata forest, the maximum productivity was 11.36 tons $ha^-1 yr^-1$ at the 49th year and the maximum yield was 115.78 tons $ ha^-1$ at the 73th year, and in C. laxiflora 7.24 tons $ha^-1 yr^-1$at the 35th year and 82.5 tons $$ha^-1 $$at the 53th year, respectively. The maximum productivities and the maximum yields of the leaves, stems and roots of the trees were calculated. The contents of nitrogen, phosphorus, potassium and organic carbon were measured.. While inorganic materials were the most abundant in the leaves, organic materials in stems. The maximumproductivities and the maximum yields of the constituents of the trees were calculated, assuming that the constituents of the trees increase allometrically. The decomposition rates were as follows: k = 0.301 for Q.serrata forest, and k = 0.364 for C. laxiflora forest. The litter of the former was decayed more slowly than that of the latter. The halftimes for decomposition were 3.2 and 1.9 years, respectively. |
