| Notes | poplar plantation ; drip irrigation ; fertilization ; N, P, and K nutrient 11-1221/S Taking ‘107＇ poplar clone （ Populus x euramericana cv. ‘74/76＇ ）plantation cultivated with surface drip irrigation at sandy land of ancient Yongding River bed in Beijing as the research object, the effects of N, P, and K absorption and accumulation as well as different N fertilization gradient on the growth of 2- and 3-year-old ‘107＇ poplar clone were studied so as to determine the optimum amount of fertilization for young （2 or 3 year-old） poplar. The results showed that ： （ 1 ） The nutrient uptake of 1- to 3-year-old ＇ 107＇ poplar clone increased year by year, the uptake in the third year was significantly greater than that in the previous two years, and the demand for various nu- trients in the order of N 〉 K 〉 P. （2） The growth of 2-year-old ‘107＇ poplar clone showed no significant difference among various treatments, the minimum N fertilizer （30 g per tree） was the best, the corresponding P was 15 g per tree, K 20 g per tr |
