| 摘 要： | 秸秆发电和气化残余物(下称草木灰),其含有丰富的大量和中微量元素,如K、Ca、P、Mg、Si、Cu、Zn、B等,其中钾含量尤为丰富。而水稻是一种喜钾和硅的作物。将草木灰作为钾肥应用于水稻的生产上,一方面可节约生产成本,另一方面还可以改善大米的品质;但草木灰同时还含有重金属元素,过量的施入势必会带来土壤环境的恶化,本文通过分析土壤中和大米中重金属含量的变化,得出本试验中草木灰的施入不会引起环境的恶化;从生产成本和水稻产量与品质上综合考虑得出处理木灰1 50%替代化学钾肥和草木灰2 75%替代化学钾肥是最佳施肥处理。

| Abstract: | The residues from straw power generation and gasification,usually called straw ash,had amounts of mass,middle,and trace elements,such as Ca,P,Si,Mg,Cu,Zn and so on,especially K element.Rice is a crop that liked absorbing K and Si elements.The straw ash can be applied on the production of rice,not only production cost is saved,but the plant quality is increased.While,the fact is not ignored that the straw ash contains some heavy metal elements.If there is no limit of application,it maybe bring the environmental harm.The contents of heavy metal elements in the soil and rice were analyzed.The results suggested that the straw ash application has no risk for the soil environmental quality.To integrate production cost,plant growth,and yield all the factors,the treatments of the straw ash 1-50 and straw ash 2-75 are better than others. |
