| 英文摘要 |
| An attempt was made to understand the biolngical degradation of Carbofuran in paddy soil and its effect on some microbial activities in soil. The results showed that the degradation of Carbofuran in paddy soil was affected by both biological factors and non-biological facters. Degradation of the pesticide had been retarded by the glucose at concentration of 1% during the early period, though the loss of the pesticide was accelerated during the Kite period. However, glucose at concentration of 0.1% did not retard degradation of Carbofuran.Carbofuran at the concentration of 50ppm or more stimulated the degradation of cellulose in four types of soils The ammonification increased significantly in silty loam while decreased in saline polder soil, when treated with high concentration of Carbofuran (500ppm). |
