Abstract

Water and nitrogen fertilizer are important influences on plants. To optimize irrigation and fertilizer schemes for cultivation of high quality first?鄄year growth Populus euramericana 74/76，a split plot design with four water treatments，three nitrogen fertilizer treatments and three replications was used with ranges of seedling height growth. Water treatments were supplied at watering to 100%，80%，60% field capacity or no watering for trees；nitrogen treatments were supplied at 0，8.00 or 15.08 gtree-1. Based on a quadratic regression of seedling heights，a regressive math model between seedling heights （y） and irrigation water （x1），nitrogen （x2） was established：y=297.378+1.737x1+5.382x2－0.008x12－0.197x22－0.015x1x2. Results showed significant differences for seedling heights （P＜0.01） with an influence of nitrogen ＞ water and nitrogen ＞ water. For seedling heights between 300 and 360 cm，the optimum combination was：irrigation water of between 8.45 - 19.25 kgtree－1 and nitrogen of between 4.57 - 9.12 gtree－1；for seedling heights between 360 and 400 cm the best combination was：irrigation of between 36.02 - 41.87 kgtree－1 and nitrogen of between 8.68 - 11.43 gtree－1. This research could contribute to water and fertilizer saving for cultivation of high quality Populus euramericana 74/76. ［Ch，3 tab. 14 ref.］
