摘要：

通过田间试验，研究在3种石灰水平下，生物有机肥对土壤养分含量、生物活性和木薯产量质量的影响。结果表明：与单施化肥比较，50%生物有机肥处理的土壤有机质、速效K含量和转化酶活性分别提高12.5%、36.7%和26.8%；土壤细菌、真菌和放线菌数量分别增加21.4%、41.8%和48.4%；25%生物有机肥处理鲜薯产量提高18.4%，淀粉产量增加17.9%。这表明施用生物有机肥能提高土壤有机质、速效K含量和微生物数量，增强土壤转化酶活性，并能提高鲜薯产量和淀粉产量。施用石灰能提高土壤细菌和放线菌数量，但降低土壤有机质、速效N和速效K含量。

Abstract:

Under three different lime levels, effects of bioorganic fertilizer on soil nutrient content, biological activity and yield and quality of cassava were investigated using field experiments. The results showed that: compared to only chemical fertilizer treatment, 50% bioorganic fertilizer treatment increased soil organic matter content, available K content, invertase activity, bacterium, fungus and actinomyces by 12.5%, 36.7%, 26.8%, 21.4%, 41.8% and 48.4%. And 25% of bioorganic fertilizer treatment increased the fresh yield by 18.4% and starch yield by 17.9%. Thus bioorganic fertilizer increased the organic matter and available K contents, microorganism numbers and invertase activity in soil, and increased fresh cassava yield and starch yield. Lime treatment increased the bacterium and actinomyces numbers in soil, but decreased organic matter, available N and K contents in soil.
