对闽东、闽北和闽南三个茶区23个土壤剖面进行研究。结果表明,0~60cm土层土壤全硒含量平均值为0383±0181μg/g(几何平均值为0377×÷1695μg/g),处于我国足硒区。用01mol/LKH2PO4溶液浸提的土壤有效硒含量平均值为0029±0008μg/g(几何平均值为0026×÷1469μg/g)。本文还讨论了土壤全硒、有效硒在土壤剖面中的分布特征,以及茶区五大土类之间的差异。
Twenty three soil profiles in three tea regions of Mindong, Northern Fujian and Southern Fujian were studied. The results showed that the average content of total selenium in 0 ~ 60cm soil layer was 0383 ± 0181μg / g (the geometric mean was 0377 × ÷ 1695μg / g), which was in the selenium area of China. The average content of available selenium in soil extracted with 01mol / L KH2PO4 solution was 0029 ± 0008μg / g (geometric mean was 0026 × ÷ 1469μg / g). The paper also discussed the distribution of soil total selenium, available selenium in the soil profile and the differences between the five major soil types in the tea area.
