摘　　要：研究于2013年以木薯品种"桂热4号"为材料,探讨了2种生物肥(木薯增产王和松土荣)和化肥对木薯产量和淀粉含量的影响。试验处理为:不施肥(CK),松土荣(M),NPK(化肥N:P2O5:K2O=100:50:100 kg/hm2),NPK+M(化肥+松土荣),75%NPK+M(75%化肥+松土荣),50%NPK+M(50%化肥+松土荣),T(木薯增产王),T+NPK(木薯增产王+化肥)。结果表明:施用松土荣和木薯增产王对木薯的鲜薯产量、淀粉含量、淀粉产量均无显著影响。其原因可能是厂家推荐施用量偏小。而化肥施用量处理显著,化肥施用量在推荐配方的75%及以上时才能显著增产。而且鲜薯产量随着化肥用量的上升而线性增加,说明了推荐配方的科学性。建议加大此2种生物有机肥的施用量。The experiment was carried out to study the effects of two bio-organic fertilizers（Zengchanwang and Songturong） and chemical fertilizer on yield and starch content of cassava by taking cassava variety GR4 as materials in 2013. The treatments were： CK（no fertilizer）,M（Songturong）, NPK（ chemical fertilizers N ∶P2O5∶K2O=100 ∶50 ∶100 kg/hm2）, NPK＋M,75 %NPK＋M,50 %NPK＋M, T（Zengchanwang）,and T＋NPK. Results： The two bio-mixed organic fertilizers had no significant effects on cassava yields, starch content and starch yield.This is probably due to the small application amount recommended by the fertilizers producer.The chemical fertilizer had significant effect on cassava yield. The yield increased linearly as the amount of NPK was over 75 % of the recommended prescription, thus explained the scientific recommended formula. Higher amount of the two bio-mixed organic fertilizers were suggested for cassava.
