Pot experiment was conducted to study the effects of organic and inorganic amendments on growth of rice in acid regurgitation field.The results showed that the grain yields of treatments with calcium magnesium phosphate,lime and self study amendment were significantly higher than those of other ameliorative treatments.Furthermore,the grain yields of these treatments increased by 322 times,222 times and 195 times compared with NPK treatment.Meanwhile,the plant height,maximum root length,dry weight of root and plant of treatments with calcium magnesium phosphate,lime and self study amendment were obviously higher in comparison to other treatments.Compared to NPK treatment,the plant height of these treatments increased by 604%，625%，563%,respectively.And the dry weight of root and plant of three treatments increased by 8917%，6264%，5028% and 1 1480%，6993%，5736%,respectively.Organic and inorganic amendments were able to improve the pH partly in paddy soil,especially for amendments of lime,self study amendment and calcium magnesium phosphate,the soil pH of these treatments were more than 45,and significantly higher than those of other ameliorative treat ments.In short,treatments with calcium magnesium phosphate,lime and self study amendment could effectively enhance soil pH,improve the growth of rice and increase grain yields significantly,which were considered as the practical and effective amendments in acid regurgitation field.In addition,humus acid,refine organic fertilizer,alkalinity organic fertilizer,alkali residue,fly ash and powdered rock phosphate were able to improve biological characteristics of rice to some extent;However,the soil acidity was not reduced significantly.
