| 英文摘要 | Burial of wheat straw in ditches and incorporation of wheat straw are the two main ways of returning wheat straw prior to rice cultivation in china. to examine the effect of burying wheat straw in ditches on ch, emissions from rice cultivation, a field experiment was conducted at yixing, jiangsu, china in 2004. ch(4) flux was measured using a closed-chamber technique in three treatments (ck, no wheat straw application; wi, evenly incorporating 3.75 t ha(-1) wheat straw into the 0.1 in topsoil; wd, burying 3.75 t ha(-1) wheat straw in 0.14-m deep by 0.25-m wide ditches). seasonal ch(4) emissions ranged from 49.7 to 218.4 kg ch(4) ha(-1). the application of wheat straw in these two ways significantly increased ch(4) emissions by 4.0-fold and 4.4-fold, respectively (p 0.05). although ch(4) flux from the non-ditch area in the wd treatment was as low as that in the ck treatment, it was counter-balanced by extremely high ch(4) flux from the ditch, which was approximately 6.0-fold as much as that from wi, leading to comparability between treatments wi and wd in total ch(4) emissions (p > 0.05). no significant difference was observed between the three treatments in grain yield (p > 0.05). the results indicated that burial of wheat straw in ditches is not a way to reduce ch(4) emission from rice cultivation. |
