摘要
本文的试验研究表明:过磷酸钙结合灌水对减少土壤胶体中的代换性钠,降低碱化度和耕层盐分,促进小麦增产等都有明显效果.实践证明该项技术措施方法简便,实用性强,是改良轻碱地并获得作物高产的行之有效方法。
The experiment research in this essay shows that adding calcium superphosphate with irrigation can bring obvious effects on reducing sodium by substitution in the soil colloid, lowing alcalization and salt in topsoil, increasing wheat production, etc. This technique has been proved to be an easy, practical usage by practice. It is most effective method to improve light alcalic soil and obtain high grain production.
