摘　　要：研究了白云石粉和生物有机肥对旱地棕红壤酸性及作物产量的影响。结果表明,施用生物有机肥、白云石粉及生物有机肥+白云石粉能降低棕红壤的酸性,提高棕红壤的肥力养分,白云石粉对棕红壤的降酸作用是一个渐进的过程。不同施肥处理与不施肥相比,小麦和花生增产达极显著水平,但它们之间的产量差异不显著。The effects of dolomite powder and bioorganic fertilizer on the acidity and crops yield in upland brownish red soil were studied. The results indicated that bioorganic fertilizer and dolomite powder decreased the acidity and increased nutrients of soil fertility in brownish red soil. Decreasing of pH-value in brownish red soil by dolomite powder was a gradually process. The fertilization of bioorganic fertilizer increased yields of wheat and peanut significantly than no fertilization, but yield difference was not significant among different fertilization treatments.
