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.
