施用有机改良剂是盐碱土改良的主要手段之一,豆渣是很好的有机改良剂,但在盐碱土的改良方面还未见应用。因此,本文以苏打盐碱土为对象,研究了豆渣培养后土壤化学性质的变化情况,结果表明,添加豆渣培养可以降低土壤pH值和总碱度,改良效果明显。 Application of organic modifiers is one of the main means to improve saline-alkali soil. Okara is a good organic modifier, but it has not been applied in the improvement of saline-alkali soil. Therefore, in this paper, the changes of soil chemical properties after okara cultivation were studied in soda saline-alkali soil. The results showed that the addition of okara could reduce soil pH and total alkalinity, and the improvement effect was obvious.
