砷毒田中水稻栽培技术的研究

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

本文简要总结了湘南砷毒土壤中水稻栽培的某些技术要点。田间试验结果表明,垄栽能使水稻增产,施P肥和稻草还田会造成水稻减产。

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.
