摘　　要：采用二次回归通用旋转组合试验设计,分析硫磺、硫酸锌、硼砂不同施用量对高淀粉玉米淀粉含量的影响。结果表明:硫磺、硫酸锌与玉米淀粉含量的关系符合二次曲线,硼砂与淀粉含量为正的线性关系;单独施用时,硫磺和硫酸锌降低淀粉含量,硼砂增加淀粉含量;硫磺与硫酸锌存在正向互作,与硼砂存在负向互作;硫酸锌与硼砂不存在互作。淀粉含量高于76.39%的施肥方案是硫磺、硫酸锌、硼砂用量分别为6.39～31.56、8.2～32.0、22.4～28.5kg/hm2。A long-term field trial was carried out to analyze effects of different Sulfur,Zinc Sulfate and Borax on the starch content of high starch maize with quadratic regression rotation design.Results showed that the relationship between Sulfur and the starch content of maize abide by conic.So does Zinc Sulfate.The relationship between Borax and the starch content of maize abide by positive linearity.Applied sulfur or Zinc Sulfate separately,the content of starch all reduced,but Borax was reverse.The effect of Su...
