摘要 以1年生青冈栎播种苗为研究对象,采用常规施肥和指数施肥方法,研究不同施肥方法对青冈栎苗苗高、地径、生物量等指标的影响。结果表明:在相同施肥量下,指数施肥与常规施肥对苗木生长影响差异不大,指数施肥的苗高是常规施肥的116.7%,生物量是107.3%,但地径生长量仅为常规施肥的78.3%;不同施氮水平处理对青冈栎苗木的苗高、地径、生物量影响显著,随着施肥水平的提高,苗木的苗高、生物量随之增加,且表现出显著性差异,但地径的差异未达到显著水平。今后应扩大施肥量的研究范围,以便在最合适的施肥量下比较指数施肥与常规施肥的差异。 The influence of normal and exponential N - fertilization methods on the height, ground diameter and biomass of one-year Cyclobalanopsis glauca seedlings was studied. The results showed that there was little difference of seedlings height and ground diameter between two methods at same level of N - fertilizer, and the seedling height and biomass of exponential fertilization treatment were 116.7% , and 107.3% to that of normal fer- tilization treatment. However, their ground diameter was only 78.3% to that of normal method. Furthermore, the seedlings height, ground diameter and biomass increased with the increase of N -fertilizer use, and showed a sig- nificant difference on seedlings height and biomass, but no significant difference existed in the ground diameter. In future, the N - fertilizer amounts should be enlarged research to confirm the suitable level and the difference of fer- tilization at normal and exponential method.
