硫硅配施对铜胁迫下水稻幼苗生长及其吸收累积铜的影响
Effect of Sulfur and Silicon Fertilizer on Growth and Absorption of Copper in Rice Seedling Under Copper Stress
摘要
Abstract
Copper is one of the main heavy metal pollutants in farmland in Jiangxi Province .In order to reduce and control the harm of copper to rice growth and improve the yield and quality of rice ,the effect of sul-fur and silicon on the form of soil copper and absorption of copper in rice seedling was investigated by means of pot experiment.The treatments included different amounts of sulfur (0、0.013 and 0.026 g/kg) and silicon (0, 0.5 and 1.0 g/kg).The results showed that:(1) Application of sulfur or silicon fertilizer ,could significantly improve the quality of rice seedling ,and accelerate the leaf emergence rate ,make shoot wider and flater and in-crease significantly the root-top ratio and biomass.(2) Application of sulfur and silicon fertilizer could reduce the absorption ( capacity ) coefficient and the transformation ( capacity ) coefficient of copper in the organs of rice seedling,and restrain the transport and transformation of copper in different rice parts ,making significant difference from the control .In conclusion ,sulfur and silicon can effectively alleviate the copper toxicity in rice seedling .The levels of 1 g/kg of silicon or 0.013 g/kg of sulfur combined with 1.0 g/kg of silicon had beffer effect.关键词
