摘　　要：以小区试验的方法选择典型的南方稻田土壤为研究对象,通过绿肥压青分别配伍3种促腐剂石灰、碳铵、石灰氮在稻田土壤上的应用试验,探讨绿肥压青配伍不同促腐剂对稻田土壤肥力及其水稻产量的影响。结果表明:绿肥压青可有效增加土壤速效磷的含量,提高土壤有机质,调控土壤碱解氮含量,起到培肥地力的作用。绿肥压青配伍不同促腐剂还可促进有机质的分解,其中以绿肥压青+有机氮处理最佳。绿肥压青和绿肥压青配伍不同促腐剂对后茬水稻具有一定得增产作用。绿肥压青、绿肥压青+石灰处理、绿肥压青+碳铵处理、处理水稻产量较无绿肥压青处理分别增产330kg/hm2、363kg/hm2、601.5kg/hm2、708kg/hm2。The application of green manure dressing with transformation promoter,the ammonium carbonate and the nitrolime used in rice field and the typical paddy soil in south were selected as materials in this study,a plot experiment was conducted to test the effects on the paddy soil fertility and rice output of green manure dressing with different transformation promoter.Results showed that green manure dressing has various advancements,such as：improving available phosphorus,improving soil organic,regulating soil alkaline hydrolysis nitrogen content and promoting fertilizer land productivity.The green manure dressing with transformation promoter was also to speed up the decomposing of soil organic.The treatment of the green manure dressing with the nitrolime is best among these.In which the green manure dressing and the green manure dressing with different transformation promoter could boost production.compared to the treatment without the green manure dressing,The rice output were respectively increased 330 kg/hm 2,363 kg/hm 2,601.5 kg/hm 2 and 708 kg/hm 2 by using the green manure dressing and the green manure dressing with transformation promoter,the ammonium carbonate and the nitrolime.
