| 摘 要： | 在连栽地４年生杉木幼林地，采用完全随机区组田间试验设计，安排Ｎ、Ｐ、Ｋ、ＮＰ、ＮＫ、ＰＫ、ＮＰＫ、Ｍ（ＮＰＫ＋微肥）、Ｃ（对照）共９个不同施肥处理，重复３次，连续观测３ａ生长情况．试验结果表明：①不同处理的肥效大小依次为：Ｍ（ＮＰＫ＋微肥）＞ＮＰＫ＞ＮＰ＞Ｐ＞ＰＫ＝Ｎ＝ＮＫ＞Ｋ＞Ｃ．施肥后第２年起，施肥处理间或与对照的生长差异达显著水平；②不同施肥因子，Ｎ、Ｐ对杉木生长比Ｋ和微肥重要．施用Ｋ肥，应以施足Ｎ、Ｐ肥为基础；③微肥对生长促进作用明显，对连栽地杉木幼林生长的重要性与大量元素Ｋ肥接近． |

| Abstract: | This fertilizer trial has been carried out on 4-year-old young Chinese fir plantation under successive rotation, adopting a complete randomized block design, and including 9 treatments as follows: N, P, K, NP, NK, PK, NPK, M(NPK+ trace elements)and control The results show that: ① The effect of the 9 different treatments in turn is :M>NPK>NP>PK=P>NK=K=N>C,and fertilizer has significant effect on Chinese fir's growth from 2 years following fertilizer ② Both of fertilizer N and P are more important for young Chinese fir plantation than fertilizer K and trace element could greatly improve Chinese fir's growth if N and P are fertilisered enough at the same time ③The effect of trace element is evident , and it is near to K which is a fair element |
