摘　　要：The concentrations of N, P, K, Ca and Mg in different organs of Phyllostachys pubescens with in sequence of age and the amount of soil nutrients were analyzed. The results showed that the content of four nutrition elements(N, P, Ca, Mg) in different organs were in the order as: leaf > branch > stem; while for K: leaf >stem >branch. The abundance of different elements in leaf, in branch and in stem respectively ranged as: N>K>Mg>P>Ca, K>N>Mg>P>Ca and K>N>Mg>Ca>P. The nutrition elements in various organs of P. pubescens were interrelated one another at some extent, significant( P <0 05) or great significant correlation ( P <0 01)existed between eleven pairs nutrient elements contents out of total thirty pairs of nutrient elements. The productivity of the woods in on_year was much higher than that in off_year, while the content of N, P and K in leaf was much higher in off_year. The nutrition in bamboo were generally correlated to nutrients of soils, eg, nitrogen content in leaf had a significant relationship with organic matter, total nitrogen, available nitrogen and available potassium in soil, phosphorus content in leaf had a strong relationship with organic matter and available nitrogen in soil, however, only good relationships in stem were found between nitrogen content and organic matter, available potassium in soil. Potassium content in branch were negatively correlated to organic matter, total nitrogen and available nitrogen in soil.
