摘要: 以黑龙江省大庆市善耕原农业科技发展有限公司试验园区盐碱土为研究对象,利用不同有机种植年限处理,对盐碱土进行田间改良试验。结果表明:相较于常规种植,施用有机肥料对土壤理化性质有明显改善,土壤肥力随有机种植年限的增加而提高,土壤有机质、速效磷、速效钾含量显著(P<0.05)高于常规种植。另外,有机种植能够降低土壤pH值、总碱度以及容重,提高土壤大团聚体含量,改善土壤结构,对盐碱土具有改良效果。

关键词: 有机种植, 土壤肥力, 团聚体

Abstract: In the present study, the effects of organic farming on improvement of saline alkali soil were explored by field experiment in the experimental farm of Shangengyuan agricultural science and technology development Co., Ltd. in Daqing City, Heilongjiang Province. It was shown that application of organic fertilizer improved the soil physical and chemical properties as compared to conventional farming. Contents of soil organic matter, available phosphorus and available potassium under organic farming were significantly (P<0.05) higher than those under conventional farming. Soil fertility was increased with the prolonged years of organic farming. Besides, organic farming was effective for improvement of saline alkali soil, as it could decrease soil pH value, total alkalinity and bulk density, and increase soil aggregates content to improve soil structure.

Key words: organic farming, soil fertility, aggregates
