| Abstract: | Objective ] This research surveyed pesticide residues of OPs vegetable soil in Nanning, it provides guidance for safety production of vegetables in Nanning. Method] The research used method of uniform putting to collect samples of soil. Pretreatment consulted GB/T14552- 2003. It used method of aluminum box to detect moisture content of soil samples, and used model PHS-25 pH meter to detect pH of soil samples. It used method of temperature programming to detect content of residues of OPs on model GC400 GC. Result] 17 samples hadn＇t residues and 57 samples had. The relevance ratio was 77.03%. Average moisture content was 20.86%, the lowest moisture content was 10.44%, and the highest moisture content was 48.88%. Average pH was 6.59, the lowest pH was 4.63, and the highest was 8.03. Conclusion] The relevance ratio of soil of vegetables was 77.03% in Nanning. Average moisture content was 20.86% , and average pH was 6.59, these hadn＇t related with residue. |
