A study on the cultivation techniques for rice(Oryza sativa L．)grown in arsenictoxic paddy soils

Field experiments were carried out to study the cultivation techniques for growing rice (Oryza sativa L．)in arsenic-toxic paddy soil in southern Hunan Province．The results showed that by application of ridge planting the rice yield could be increased．But rice grain yield was decreased when phosphate fertilizer or rice straw was applied to the arsenic-toxic soils.
