| 摘 要： | 目的]研究长期施肥对红壤性水稻土根际土壤可溶性有机碳的影响。方法]采用田间定位试验,研究了不同施肥制度下红壤性水稻土根际土壤可溶性有机碳（DOC）的动态变化。结果]与非根际土壤相比,根际土壤DOC含量的变化趋势呈现为水稻分蘖期低、抽穗期高、结实期低、成熟期高;而与移栽前相比,水稻收获时土壤DOC含量增加明显。结论]种植水稻有利于保持和提高土壤有机碳库质量。 |

| Abstract: | Objective] The research aimed to study the effects of long-term fertilization on the content of dissolved organic carbon in rice rhizosphere soil.Method] Filed experiment with different fertilization systems was conducted to study the change of dissolved organic carbon(DOC) in rice rhizosphere soil.Result] Compared with non-rhizosphere soil,DOC content in rhizosphere soil reduced at tillering stage,increased at heading stage,decreased at grain-filling stage and increased at maturity stage.Besides,compari... |
