呋喃丹在稻区土壤-水体中的持留、迁移变化
- PERSISTENCE AND MOVEMENT OF CARBOFURAN IN THE SOIL-WATER SYSTEM AT RICE CULTURED AREA
- 摘要：采用田间试验与模拟试验相结合的方法,研究了呋喃丹在南方水稻地区土壤-水体中的残留动态,得出了一些基本数据,为呋喃丹在稻田的安全使用提出了合理评价。
- Abstract：According to field and trial tests, the half-life of carbofuran in different paddy soils were shown to be 8-10 days after being applied over the surface of the soils. In the potting tests, its half-life was approximately twice as much as in the field. The half-life of carbofuran in pond water were 2 days for early rice and 5-6 days for late rice respectively. They were 1.0 to 4.7 times longer than these in the trial tests. The results indicated the continuous transfer of carbofuran from the soil into the pond water nearby and to the groundwater underneath. A significant correlation was also found between the soil residue level and the amount washed into the pond water.
