摘要： 为了研究连续稻秆还田腐熟对稻田土壤的培肥增产效应，采用定点监测的方法，在福建6个典型县（市）布置定位试验3年。结果表明，与基础土壤相比，连续3年稻秆还田腐熟，各试验区土壤有机质提升11.3%，容重下降12.9%，均达到极显著差异水平；土壤全氮、全磷、全钾、有效磷、速效钾、缓效钾和阳离子交换量分别增加17.3%、12.6%、12.7%、21.6%、37.7%、5.2%和10.1%，pH变化不明显；比常规施肥(CK)，后季作物平均增产7.1%，增产效应为马铃薯(8.8%)＞莴苣(7.2%)＞水稻(6.8%)＞烟叶(5.5%)。稻秆还田腐熟不仅培肥地力，而且促进增产稳产。

Abstract: In order to study the continuous straw counters-field rotten on paddy soil fertilizer production effect, with the method of fixed- point monitoring, effect of rice straw returning to field with decomposition of soil fertility and increasing production decorating positioning test in six typical counties of Fujian province for 3 years were studied. The results showed that compared with the foundation soil, each experimental zone of soil organic matter increased 11.3% and the density declined 12.9%, reached significant difference levels after rice straw to field with decomposition finishing 3 years in a row; Soil total nitrogen, total phosphorus, total potassium, effective phosphorus, available potassium, slowly available potassium and cation exchange capacity increased respectively 17.3%, 12.6%, 12.7%, 21.6%, 37.7%, 5.2% and 10.1%, pH value change was not obvious; compared with conventional fertilizer (CK), after the season crop yield was 7.1% higher than that of the average, to increase production effect for potatoes (8.8%)＞lettuce (7.2%)＞rice (6.8%)＞leaf (5.5%). Rice straw returning decomposing not only enriching the soil fertility, and promote the yield and stable yield.
