摘要

通过长期定位试验,研究不施肥（CK）、100%化肥（CF）和50%化肥+50%有机肥+豆科植物（IF）等3种处理对茶园黄红壤团聚体及其有机碳（TOC）和全氮（TN）分布的影响。结果表明,各处理均以≥2βmm水稳性团聚体占优势,其质量分数高达54.95%~66.97%;同时,该级水稳性团聚体中TOC、TN储量分别是相应全土总量的33.31%~45.45%和33.76%~46.60%。其中,不同粒径水稳性团聚体TOC和TN的贡献率在IF和CF处理中的大小排序为（≥2βmm）>（<0.5~0.25βmm）>（<1~0.5βmm）>（<2~1βmm）>（<0.25~0.106βmm）,而在CK中为（≥2 mm）>（<1~0.5βmm）>（<0.5~0.25βmm）>（<2~1βmm）>（<0.25~0.106βmm）。与CK相比,IF处理可显著（P<0.05）提升≥2βmm水稳性团聚体的含量和平均重量直径,增加该粒径水稳性大团聚体中TOC和TN的含量及储量。而且,≥2βmm水稳性团聚体含量与全土TOC、TN含量均呈极显著（P<0.01）的正相关。但是,IF处理土壤不同粒径团聚体的C:N比值一般比CK低。综上表明,处理IF不仅能增加土壤及其水稳性团聚体中TOC和TN的含量及储量,而且提高水稳性团聚体的稳定性,是茶园黄红壤固碳供氮的合理培肥模式。

Abstract

Application of livestock manures and plant residues is a feasible practice to largely mitigate soil-degradative trends by increasing amounts of organic matter. However, long-term effects of fertilization regimes on the distribution of organic carbon (TOC) and total nitrogen (TN) in aggregate size fractions were poorly documented in tea (Camellia sinensis (L.) Kuntze) plantations in subtropical areas. A 10-year study was thus conducted to elucidate the impacts of fertilization patterns on the stability and allocation of TOC, TN and C/N ratio within water stable aggregate (WSA) fractions in soils under non-fertilization control (CK), chemical fertilizers only (CF), and integrated use of chicken manure and legume straw with chemical fertilizers (IF), respectively. Soil (0-20 cm) samples were collected and separated into ≥2, <2-1, <1-0.5, <0.5-0.25 and <0.25-0.106βmm aggregate classes by wet sieving, and finally used for TOC and TN analysis. The results showed that the IF treatment significantly (P<0.05) increased TOC and TN storage in all aggregate fractions relative to that of CK. Irrespective of the fertilization patterns, tea soils in subtropical China stored higher amounts of TOC and TN in the ≥2βmm water-stable fraction. In terms of the TOC and TN storage, the order of different aggregate fractions in IF- and CF-treated soils was (≥2β mm ) > (<0.5-0.25βmm) > (<1-0.5βmm) > (<2-1βmm) > (<0.25-0.106βmm), whereas that of CK-treated soils was (≥2βmm) > (<1-0.5βmm) > (<0.5-0.25βmm) > (<2-1βmm) > (<0.25-0.106βmm). Furthermore, the percentage of WSA ≥2βmm ranged from 54.95% under CK to 66.97% under IF treatment. Furthermore, TOC and TN adhered to WSA ≥2βmm, which accounted for 33.31%~45.45% of TOC and 33.76%~46.60% of TN in bulk soils under all treatments. Meanwhile, the IF treatment significantly (P<0.05) increased mean weight diameter (MWD) of aggregates as compared to that in CK- and CF- treated soils. However, a lower C:N ratio was observed in different aggregate fractions in IF-treated soils compared with that of CK. Additionally, WSA ≥2βmm was positively and significantly correlated with TN and TOC contents. In conclusion, the IF treatment improved aggregate stability, increased C and N storage in bulk soil and aggregates, and thus enhanced soil quality in tea farms in subtropical China.
