摘　　要：在赤红土和石灰性土中，钙镁磷肥及其镁磷效应的研究结果表明，在赤红土中施钙镁磷肥于水稻优于施过磷酸钙，其中镁和磷对水稻的生物产量有极显著的增产效果；在石灰性土中，钙镁磷肥比过磷酸钙稍差，但二者未达显著差异。Calcium-magnesium-phosphate (Ca-Mg-P) and it's magnesium-phosphate (Mg-P) effects in the crimson soil and lime soil were studied. The results were showed: as for the rice, the function of Ca-Mg-P was much better than that of calcium superphosphate in the crimson soil. Mg and P had increased significantly the biological yields of rice in the crimson soil. However, the Ca-Mg-P was slightly inferior to calcium superphosphate, but no significant difference was showed.
