英文摘要	The effects of lanthanum on rice growth, phosphorus uptake and phosphorus chemical fractions in rice were studied with split-root solution culture. Results show that low concentration of La (0.05similar to1.5 mg . L-1) significantly in-creases rice yield while high La concentration (9similar to30 mg . L-1) markedly decreases rice yield. When La concentration is 0.05similar to0.75 mg . L-1, La increases stem and root dry weight, but the difference is not statistically significant. La significantly increases EDTA-P and inorganic-P content in the stem and root. More than 80% of the increase of phosphors content in roots attributing to increase of EDTA-P and inorganic-P. Low La concentration (0.05similar to0.75 mg . L-1) increases nucleic-P content in root, but high La concentration (30 mg . L-1) decreases nucleic-P and ester-P content in root. The residue-P content increases in the root and stem. Also the relationship between the chemical fractions of phosphorus and its uptake by rice was discussed.
