Effects of soil conditioner on acidic soil improvement and yield of rice

摘要: 为探索土壤调理剂对酸性土壤的改良及增产效果,在大田县水稻田进行“施地佳”土壤调理剂应用效果试验,结果表明:土壤调理剂处理的土壤pH、有效磷和速效钾含量均有提高,其中土壤pH提高0.3个单位,改良效果明显;比不施土壤调理剂处理每667 m²增收稻谷58.3 kg,增产率10.4%,差异达显著水平(P<0.05)。

Abstract: Experiments of application effect of “Shidijia” soil conditioner in acid paddy field Datian County. The results showed that soil pH, available P and available K contents of soil conditioner treatment were increased, the soil pH increases 0.3 units, improving effect was obviosly;and yield raised 58.3 kg every 667 m² than control treatment, increased by 10.4%, the difference reached significant level (P<0.05).
