Due to the selection of new soil extractant (NMSNMSNRY), correlation coefficients between rare earth oxide content in leaves of some plants and soluble rare earth elements in soil were very high.

在测定土壤中可溶态稀土元素含量时，由于选用了新型提取剂(NMSNMSNRY)，使测得的土壤中可溶态稀士元素的含量与一些植物叶片中的稀土元素含量有很好的相关让。

The correlation didn't reach significant level. 0.2 molL-1 K2SO4 wasn't the suitable available Se extractant for paddy soil.

K2SO4对土壤硒的浸提量低，与植株含硒量间的相关性不显著，不适宜作水稻土有效硒的提取剂。
