摘　　要：试验以2年生圆柏移栽苗为试材,研究了不同氮肥追施量对圆柏生长及叶绿素的影响。结果表明:8 g/株处理地径在6、7月份分别比对照提高了34.58%、48.94%,差异显著;株高8g/株处理在5、6、7月份处于最高值,与对照相比分别提高了19.07%、39.81%、49.37%,其中6、7月份与对照之间存在显著差异;干物质积累量8g/株处理比对照提高了29.33%,差异显著;叶绿素含量8g/株处理在6、7月份与对照相比提高了35.96%、49.46%,差异显著。综合分析认为,圆柏追施氮肥量为8g/株时对促进移栽苗生长效果最佳。The experiment used 2 year old Sabina chinensis transplanting seedlings as test materials,and then studied the effects of different nitrogen fertilizer on growth and chlorophyll of Sabina chinensis,The result shows that： the 8 g/plant treatment which ground diameter was increased than the control 34. 58%,48. 94%when in June and July and then it was have significant difference; plant height which 8 g/plant treatment at the highest value when in May,June,July,and then it was higher than control 19. 07%,39. 81%,49. 37%,at the same times,it was have significant difference with control when in June and July; dry matter accumulation which 8 g/plant treatment was higher than control 29. 33% and then it was have significant difference; chlorophyll content which 8 g/plant treatment was higher than the control 35. 96%,49. 46% when in June and July,and then it was have significant difference. Comprehensive analysis that Sabina chinensis when the concentration of chasing nitrogen fertilizer was 8 g/plant,the growth rate of transplanted seedlings was the best.
