摘　　要：通过田间对比试验,研究不同用量液体水溶性有机肥对膜下滴灌棉田土壤pH和有机质含量的影响。结果表明:不同用量液体水溶性有机肥可以有效降低棉田土壤pH值升高的幅度、有效降低棉田有机质含量降低的幅度,当随水滴施液体水溶性有机肥的施用量合理时可以降低棉田pH值、提高棉田有机质含量。The comparative field experiments were carried out to study the dynamic change influences of different dosage of water-soluble organic liquid fertilizers on soil pH and organic matter in drip irrigation cotton field.The results showed that different dosage of water-soluble organic liquid fertilizers could effectively reduce the increasing range of soil pH in cotton field and the decreasing amplitude of the organic matters.Through drip irrigation,the reasonable dosage of water-soluble organic liquid fertilizers could reduce the soil pH in cotton field and improve the organic contents.
