而其它盐提取剂通过延长提取时间,可以提取部分非交换态钾,在非交换态钾为当季作物主要钾源的土壤上,作为有效钾提取剂的优越性甚至会超过醋酸铵法。阳离子交换树脂法也可提取土壤非交换态钾,但操作较为繁琐,该方法更适用于原位研究土壤钾素的迁移、扩散等特性。四苯硼钠法提取效率较高,通过调节其提取力,可提取不同程度的非交换态钾,将可能成为适用于各类土壤和作物的土壤有效钾测定方法。 希望能翻译的专业一些,是论文要用的,谢谢谢谢~~ 鄙人的专业英语实在是太烂了。 |

But other salt extraction agents can extract part of non-exchangeable K by extending the extraction time.On the soil of seasonal crops that is as the main source of the non-exchangeable K ,as Superiority of an effective K even exceeds the method of ammonium acetate.The method of cation exchange resin can also extract soil non-exchangeable K,but the operation is more complicated,this method is more suitable for situ studying migration of soil potassium,diffusion and so on.The method of sodium tetraphenylborate is higher extraction efficiency.It can extract different levels of non-exchangeable K by adjusting the extraction force,and may be used of measuring available potassium of every types of soil and crop soil. |
