摘要

为探明稻秸（稻草）及其不同组分（腐解稻秸、可溶性有机物和去活稻秸）对红黄泥水稻土微生物量碳、氮（MBC、MBN）和可溶性有机碳、氮（DOC、DON）含量的影响，通过室内恒温培养试验，研究了长期淹水条件下，添加稻秸及其组分对MBC、MBN、DOC和DON的影响。结果表明，与对照（S处理）相比，添加稻秸（RS+S处理）、腐解稻秸（DRS+S处理）和去活稻秸（NARS+S处理）均提高了MBC，提高幅度分别为11.17%（p＜0.01），1.83%和6.25%（p＜0.05），添加可溶性有机物（DOM+S处理）处理降低了MBC，降低幅度为2.67%；RS+S处理提高了MBN，提高幅度为15.29%，DRS+S、DOM+S和NARS+S处理均降低了MBN，降低幅度分别为15.19%，3.09%和15.92%。与S处理相比，RS+S、DRS+S、DOM+S和NARS+S处理均极显著提高了红黄泥DOC（p＜0.01），提高幅度依次分别为13.33%，10.88%，6.81%和11.41%；RS+S、DRS+S和DOM+S处理均显著提高了红黄泥DON（p＜0.05），NARS+S处理极显著提高了红黄泥DON（p＜0.01），提高幅度依次分别为6.96%，10.84%，10.12%和13.41%。与S处理相比，DRS+S和NARS+S处理极显著提高了MBC/MBN，RS+S处理显著降低了MBC/MBN，DOM+S处理对MBC/MBN几乎没有影响；各处理对DOC/DON没有显著影响。稻秸及其不同组分对红黄泥水稻土MBC、MBN、DOC和DON含量的影响基本一致，但影响程度存在差异，稻秸和去活稻秸影响较大。结果可为稻秸及其不同组分对MBC、MBN、DOC和DON的影响机理提供基础数据，进一步揭示稻田土壤速效养分的来源与转化关系，为农业生产中秸秆的科学利用和稻田土壤肥力定向培育提供科学依据。

Abstract

This study aimed to analyze the effects of rice straw (rice straw) and its different ingredients (decomposed rice straw

dissolved organic material

non-active ingredient rice straw) on microbial biomass carbon

nitrogen (MBC

MBN) and dissolved organic carbon

nitrogen content (DOC

DON) in the well-drained paddy soil from quaternary red clay. An indoor thermostatic incubation experiment was carried out. The results showed

compared to the control (S treatment)

rice straw (RS+S treatment)

decomposed rice straw (DRS+S treatment) and non-active ingredient rice straw treatment (NARS+S treatment) increased by 11.17% (p＜0.01)

1.83% and 6.25% (p＜0.05) in MBC

respectively

dissolved organic material treatment decreased by 2.67% in MBC. RS+S treatment increased by 15.29% in MBN

while DRS+S

DOM+S

and NARS+S decreased by 15.19%

3.09% and 15.92% in MBN

respectively. Compared with S

RS+S

DRS+S

DOM+S and NARS+S treatments significantly increased by 13.33%

10.88%

6.81% and 11.41% in DOC

respectively (p＜0.01); RS+S

DRS+S and DOM+S treatments significantly increased by 6.96%

10.84% and 10.12% in DON

respectively (p＜0.05); and NARS+S treatment significantly increased by 13.41% in DON (p＜0.01). Compared with S

DRS+S and NARS+S treatments significantly increased MBC/MBN (p＜0.01)

while RS+S treatment significantly decreased the MBC/MBN (p＜0.05)

and DOM+S treatment almost had no effect on MBC/MBN. Among the treatments

there were no significant differences in DOC/DON.As for MBC

MBN

DOC and DON in the well-drained paddy soil from quaternary red clay

rice straw and the different ingredients work in the same direction

but in different degree. The findings can provide a basic data for understanding the controls of rice straw and its different ingredients on MBC

MBN

DOC and DON

and a scientific basis for revealing the relationship between the source and conversion of available nutrient in paddy soil

which are useful for improving the use efficiency of Rice Straw and soil fertility.
