摘要: 比较了6个茶树品种的氮素效率差异。结果表明,在4种施氮条件下,生物量增加值、新梢生长量、氮素吸收效率、氮素生理利用效率、氮素经济效率和总的氮素效率存在着显著的品种间差异。氮素效率的两个子性状—吸收效率和生理利用效率对其贡献大小不同,吸收效率是决定不同品种茶树氮素效率差异的主要因素。

Abstract: Pot experiment with 6 tea plant genotypes was conducted to investigate the genotypic difference in N efficiency at 4 N levels. The results showed that there were significant difference in increased biomass yield, increased new shoots, N uptake efficiency, N physiological utilization efficiency, N economic efficiency and N use efficiency among 6 tea plant genotypes. The difference of N uptake efficiency was the main fact that resulted in the N use efficiency among tea plant genotypes.
