摘要

采用野外模拟试验,通过设计4种氮处理〔CK (对照,不施氮)、LN(低氮,5 kg·hm-2·a-1)、MN(中氮,10 kg·hm-2·a-1)、HN(高氮,15 kg·hm-2·a-1)〕,研究了氮沉降对天山云杉凋落叶分解及养分释放的影响。结果表明:① 分解24个月后CK凋落叶干重残留率分别是LN、MN和HN的1.04倍、1.16倍和1.23倍,且4种处理间差异显著(P<0.05)。CK条件下凋落叶分解50%为4.58 a,分别比LN、MN和HN多0.46 a、0.75 a和1.35 a;相应地分解95%需要的时间分别多2.01 a、3.24 a和5.87 a,说明施氮对天山云杉凋落叶的分解起到了促进作用,且促进作用随着氮沉降量的增加而加大。② 从凋落叶月分解速率看,表现为HN>MN>LN>CK,且随着分解时间的延长,4种处理间的差异逐渐缩小。③ 氮沉降促进了天山云杉凋落叶中木质素和纤维素的分解,同时促进了C元素的释放,增加了N元素的累积,降低了C/N值。

Abstract

A field simulated experiment was conducted to research the effects of nitrogen deposition on the decomposition and nutrient release of leaf litter of Picea schrenkiana. Four treatments were designed,i.e. the CK (contrast,non-addition nitrogen),LN (low nitrogen,5 kg·hm-2·a-1),MN (mid nitrogen,10 kg·hm-2·a-1) and HN (high nitrogen,15 kg·hm-2·a-1). The results are as follows:① After a 24-month decomposition,the residual rate of leaf litter dry weight of P.schrenkiana in CK was 1.04,1.16 and 1.23 times of that in LN,MN and HN respectively,and the difference among the four treatments was significant (P<0.05). The required time for 50% decomposition of leaf litter in CK was 4.58 a,which was 0.46 a,0.75 a and 1.35 a longer than that in LN,MN and HN,and correspondingly,it was 2.01 a,3.24 a and 5.87 a longer for 95% decomposition,respectively. The results revealed that nitrogen deposition promoted the decomposition of leaf litter of P.schrenkiana,especially at latter stage of decomposition. Moreover,the promotion was more obvious with the increase of nitrogen deposition; ② Monthly decomposition rate was in an order of HN>MN>LN>CK. Moreover,the difference among the four treatments was gradually reduced with the time of decomposition; ③ Nitrogen deposition promoted the release of lignin,cellulose and carbon in leaf litter of P.schrenkiana,and increased the accumulated nitrogen,and decreased the C/N.

Key words： nitrogen decomposition; leaf litter decomposition; nutrient release; Picea schrenkiana; mountain forest; arid area
