Effects of VIP Technology on Reducing Cadmium under Different Cadmium Pollution De-gree Paddy Soil
摘要
Abstract
In order to explore the comprehensive effects of VIP technology(V,low cadmium planting varieties;I,Optimize water man-agement; P, Liming)on reducing cadmiumin under different pollution degree paddy soil, a field experiment with 38 mounds of cad-mium pollution paddy soil was carried out in Hunan province in 2014. The results showed that the cadmium content of early rice of CK were 0.191, 0.199, 0.295 and 0.423 mg/kg in slight, mild, moderate and severe conditions, respectively. By using VIP technology, early rice cadmium content were 0.110, 0.152, 0.157 and 0.307 mg/kg, which reduced 42.4%, 23.6%, 46.8% and 27.4% compared with CK. The cadmium content of late rice were 0.153,0.201,0.397and 0.604 mg/kg,which reduced 45%,24.2%,32.6% and 22.4% compared with CK.Above all,the comprehensive effects of reducing cadmium(VIP)of comprehensive measures of cadmium reduction has reduced the cadmium content in brown rice under different degree of pollution. It can make the cadmium content of slight, mild soil pollution to reach the safety national food standards.But how to reduce the cadmium content in moderate and severe pollution soil still needs further research.关键词
