不同配方含硒叶面肥对水稻富硒降镉的影响
Effects of different foliar fertilizers containing Se on Se-enrichment and Cd-reduction in rice
摘要
Abstract
[Objective]The effects of different formulas of foliar fertilizer containing selenium(Se) nutrition on Se-en-richment and Cd-reduction in rice and suitable application environment were studied to provide reference for product deve-lopment and utilization of Se-enrichment and Cd-reduction foliar fertilizers. [Method]Spraying water was used as control (CK), four foliar fertilizers containing Se were prepared. They were used in low Se and medium-and-low cadmium(Cd) polluted field and rich Se and high Cd polluted field. Se and Cd contents in polished rice were measured after rice harvest.[Result]In low Se and medium-and-low Cd polluted field, all formulas of foliar fertilizer containing Se could enrich Se content and reduce Cd content in polished rice. Compared to CK,formula 1-4 improved Se content in polished rice by 57.3%, 83.4%, 27.1% and 108.6% respectively;and significantly reduced Cd content in polished rice by 62.5%, 88.6%, 88.9% and 86.1%(P<0.05,the same below) respectively. In rich Se and high Cd polluted field,compared to CK, formula 1-4 improved Se content in polished rice by 280.1%,422.1%,152.7% and 503.2% respectively. But Cd contents in polished rice of different treatments presented insignificant difference compared with CK(P>0.05). [Conclusion]When foliar ferti-lizer is acid and containing nitrogen, phosphorus and potassium, foliar fertilizers containing Se has the optimal Se-enrich-ment effects for polished rice. However, foliar fertilizer containing zinc sulfate and magnesium sulfate can reduce its effi-ciency on Se-enrichment in rice. In low Se and medium-and-low Cd polluted field, foliar fertilizer containing Se can reduce Cd content in polished rice significantly; but it has no such effect on rich Se and high Cd polluted field.关键词
