Abstract

The restoration effect of the paddy field of the heavy metals pollution application the mineral micropores fertilizer with potassium, silicon and calcium (MFPSC) was studied with the field experiment. The results showed the total grain number per panicle, the actual number grains per spike, and the ripening rate were increased, while the rice yield was promoted, and the increase ratio was up to 7.5 -16.0%, after the MFPSC was applied. The content of the alkali-hydrolyzable nitrogen, the available phosphorus, and the soil available potassium was improved, and the soil available Cd was decreased, so the Cd accumulation of the rice grain was induced and prevented, the Cd content of the rice grain was decreased, its greatest value was up to 38.6%, when MFPSC was employed. The trial results suggested that the application rates could not be less than 95kg/667m2.

Key words
