研究成果表明，贵州省耕土中可溶态稀土含量分布变化大致可划分为五个区：①毕节－大方－织金－六枝以西高值区；②平坝－贵阳－开阳中值区；③册享－惠水－从江（以南）低值区；④毕节－遵义－道真（以北）低值区，⑤龙里－余庆－铜仁低值区。其区域背景总概貌为：西高东低，从中部向北向南递减．各土壤类型的∑ＳＲＥ２Ｏ３含量趋势为：黄棕壤＞紫色土＞石灰土＞红壤＞水稻土（黑壤或黄壤）．耕土中稀土元素归－化模式曲线反映出Ｅｕ和Ｌｕ亏损时，∑ＲＥ２Ｏ３为低值．归一化曲线较平直时为高值。轻稀土和重稀土的比值∑ＬＲＥＥ／∑ＲＥＥ（％）＞９０时，∑ＳＲＥ２Ｏ３为低值，反之为较高值。多数耕土中粘土矿物，尤其是高岭石含量较高时∑ＳＲＥ２Ｏ３相应较高，反之较低。用微机进行多元统计分析表明：∑ＳＲＥ２Ｏ３和∑ＲＥ２Ｏ３呈显著正相关．∑ＳＲＥ２Ｏ３与土壤颜色及母岩地层时代的相关系数分别为＋０．１６４和＋０．１３５，也呈显著正相关关系。即二叠系三叠系地层分布区的黄棕壤和紫色土的∑ＳＲＥ２Ｏ３大多显著高于黄壤和水稻土（黑壤）。最后分析了影响我省耕土可溶态稀土含量高低变化的各种因素，并建议推广稀土微肥应优先放在三个∑ＳＲＥ２Ｏ３低值区进行，同时以黄壤、红壤?
The results show that the distribution of dissolved rare earth in the cultivated soil of Guizhou Province can be roughly divided into five areas: (1) Bijie-Dafang-Zhijin-Liuzhi-West high-value area; ② Pingba-Guiyang-Kaiyang median value area; ③ Book enjoy - Huishui - from the river (south) low value area; ④ Bijie - Zunyi - Daozhen (north) low value area, ⑤ Longli - Yuqing - Tongren low value area. The general background of its regional background is: West High East low, decreasing from the central north to the south. The trend of ΣSRE2O3 content in each soil type is yellow brown soil> purple soil> lime soil> red soil> paddy soil (black soil or yellow soil). The regression curve of rare earth elements in arable land reflects the loss of ΣE2O3 when the loss of Eu and Lu is low. The normalized curve is higher when flat. When the ratio of light rare earth to heavy rare earth Σ LREE / ΣREE (%)> 90, ΣSRE2O3 is low, and vice versa. The majority of clay in the soil, especially kaolinite higher ΣSRE2O3 corresponding higher, whereas the lower. Multivariate statistical analysis using computer showed that: ΣSRE2O3 and ΣRE2O3 showed a significant positive correlation. Correlation coefficients between ΣSRE2O3 and soil color and age of the parent rock strata were +0.164 and +0.135, respectively. There was also a significant positive correlation. The ΣSRE2O3 of yellow-brown soil and purple soil in Permian Triassic strata are mostly higher than yellow soil and paddy soil (black soil). Finally, the paper analyzes various factors that affect the level of soluble rare earth in the cultivated soils of our province, and suggests that the promotion of rare earth fertilizers should be preferentially placed in the three ΣSRE2O3 low-value areas, with yellow soil and red soil?
