摘要

[目的

]

探讨典型黑土区退耕还林过程中不同凋落物输入对土壤氮组分的影响，为黑土土壤养分调控、退耕还林树种筛选及植被重建提供理论依据。[方法

]

试验设银中杨凋落物(Populus alba)、落叶松凋落物(Larix gmelinii)及玉米秸秆3种处理，并设置空白对照。将各处理凋落物与风干土壤混合后在25℃培养箱中培养28 d，分别测定土壤氮组分含量及两种酶〔β葡糖苷酶(βG)和脲酶(URE)〕活性，并利用方差分析和Pearson相关性等方法分析，探讨不同种类凋落物输入对黑土区土壤氮素及酶活性的影响。[结果

]

方差分析表明，在3，7，14，28 d时添加银中杨凋落物处理的TN值显著高于对照、添加落叶松凋落物及玉米秸秆(p＜0.05)；3种凋落物的输入对土壤速效氮(AN)含量没有显著影响；对于微生物量氮(MBN)，添加银中杨凋落物的处理在7和14 d的提升效果显著高于对照、添加落叶松凋落物及玉米秸秆这3种处理(p＜0.05)，在28 d时添加银中杨和落叶松凋落物的处理的MBN值显著高于对照和玉米秸秆(p＜0.05)；添加不同种类凋落物均显著降低土壤无机氮含量。βG与NH

-N，NO

-N呈极显著、显著负相关，与URE，TN，AN均呈极显著正相关；URE与总有机碳(TOC)，MBN，TN呈显著、极显著相关性，与NH

-N呈显著负相关。[结论

]

3种外源输入物分解对土壤全氮、速效氮、微生物生物量氮、无机氮和酶活性含量有密切联系，凋落物的输入有利于促进土壤养分循环和积累，其中阔叶树种银中杨的凋落物输入对土壤氮素及酶活性的提高效果最为显著。

Abstract

[Objective] The impact of different litter inputs on soil nitrogen fractions during the process of returning farmlands to forests in typical black soil regions was explored

in order to provide a theoretical basis for soil nutrient regulation

tree species selection for afforestation

and vegetation restoration. [Methods] The experiment included three treatments (Populus alba litter

Larix gmelinii litter

and maize straw) and a blank control. The litter from each treatment was mixed with air-dried soil and incubated at 25 ℃ for 28 days. The content of soil nitrogen components and the activities of the two enzymes 〔β-glucosidase (βG) and urease (URE)〕 were then measured. Variance analysis and Pearson’s correlation were used to investigate how different litter inputs affect soil nitrogen and enzyme activities in black soil regions. [Results] Variance analysis showed that at 3

and 28 days

the total nitrogen (TN) values in the P. alba litter treatment were significantly higher than those in the control

L. gmelinii litter

and maize straw treatments (p<0.05). The input of the three kinds of litter did not significantly impact the soil available nitrogen (AN) content. For microbial biomass nitrogen

inorganic nitrogen

and enzyme activities (MBN)

the P. alba litter treatment displayed a significantly greater increase at 7 and 14 days compared to the control and the other two treatments (p<0.05). At 28 days

the MBN values in both the P. alba and L. gmelinii litter treatments were significantly higher than those in the control and maize straw treatments (p<0.05). All litter treatments significantly reduced the soil’s inorganic nitrogen content. βG was highly or significantly negatively correlated with NH+4-N and NO-3-N; it was highly positively correlated with URE

and AN. URE was significantly or highly significantly correlated with TOC

MBN

and TN and negatively correlated with NH+4-N. [Conclusion] The decomposition of the three types of exogenous inputs was closely linked to the soil’s TN

the AN

MBN

inorganic nitrogen

and enzyme activities. Litter input promoted soil nutrient cycling and accumulation

with litter input from the broadleaf tree species P. alba having the most significant impact on improving soil nitrogen and enzyme activities.
