摘　　要：在滨海盐碱地对高粱施用过磷酸钙的效果进行了试验研究。结果表明,在高盐条件下,施用适量过磷酸钙时(375kg·hm-2),高粱增产显著,增产达8.1%。通过试验证实,过磷酸钙可为土壤提供磷素营养,在改良盐碱土上有增产提质的效果,可作为盐碱土的有效改良剂。Effect of applying superphosphate to sorghum was studied in coastal saline. The result showed that under high salt conditions, when the appropriate amount of superphosphate was applied （375 kg. hm-2）, sorghum yield up 8.1%, and superphosphate provides soil with phosphorus, which proved that applying superphosphate could increase production and improve quality.
