添加发酵秸秆粉对盐碱土壤肥力的影响

Effect of adding fermented straw powder on the fertility condition of saline alkali soil

将发酵秸秆粉分别加入盐碱土壤中,并对土壤的pH值、含盐量、有机质以及速效N、P、K含量进行测定与分析.结果表明,发酵秸秆粉的加入使土壤pH值降低,有机质及速效养分含量明显提高,显著改善了盐碱土壤的肥力状况.

After fermented straw powder （maize and wheat） was mixed with saline alkali soil , the pH , saltness , organic matter and the content of available N , P , K of the soil were measured and analyzed , The results shows that addition of fermented straw powder could reduce the soil pH while the organic matter and available nutrients was obviously increased , which remarkably improve the fertility condition of saline alkali soil.
