摘要
2014年在大田试验条件下,以单施氮磷钾化肥为基准,探讨钢渣粉施用对双季水稻的产量、养分吸收、土壤养分及土壤和稻米中铬含量的影响。结果表明:与单施化肥相比,施用钢渣粉有利于提高早稻产量和促进水稻对硅素养分的吸收,而对晚稻的产量影响较小;可以提高土壤中有效硅的含量和p H值,同时对土壤和稻米中铬含量的影响不大。
Based on the NPK fertilizers under the condition of field experiment in 2014, discusses the influence of rice yield, nutrient absorption, soft nutrient and soil and chromium content in rice when using steel slag powder on the double season rice field. Results show that application of steel slag powder is helpful to improve the early rice yield and promote the absorption to the silicon, and less impact on the yield of late rice Compared with only fertilization of chemical fertilizer. It can improve the effective of the silicon content in soil and pH value, has less influence of chromium content in the soil and flee.
