STUDIES ON THE CYCLING OF NUTRIENT ELEMENTS IN THE ECOSYSTEM OF THE OIL-TEA CAMELLIA PLANTATION
油茶林生态系统中营养元素循环的研究

In the paper the content, net accumulation and cycling of nutrient elements in two oil-tea plantations under the optimization management measures were studied. Taking the oil-tea plantation as on example, the cycle process of nutrient elements in the ecosystem was analysed and some dynamics models of N, P, K elements were put forward. The results are as follows: (1) concentrition of nutrient elements in organs of the oil-tea standing crops tends toward N>K>Mg>Ca>P, the highest concentration of nutrient elem...
