摘 要: | [目的]为了明确不同的播期、钾肥和钙硼比例对油菜根肿病的控制效果。[方法]通过3因素5水平二次通用旋转组合设计方案,建立回归模型及对其进行解析、寻优和频数分析。[结果]结果表明,所设各试验因素对油菜根肿病控病效应的大小顺序为播种期(X1)〉钾肥(X3)〉钙硼比(X2)。[结论]3因素对防治油菜根肿病的最优配比方案:播种期为10月10日或者11日,钙硼比[氢氧化钙Ca(OH)2/硼砂]比值为26.85,钾肥(KCl)8.37 g/m^2。

Abstract: | Objective The aims was to define the com prehensive effect of different sowing time, potassium fertilizer and calcium-boron ratio on rape clubroot disease. [Method]Through the designs of three-factors and five-levels as well as the quadratic universal rotary assembly,regression models were built, and it was analyzed, optimized, and conducted with frequency analyses. [Result] The extent of impact of all experimental factors to clubroot was sowing time(X1) 〉potassium fertilizer (X3) 〉 calcium-boron ratio(X2). [Conclusion]The optimal ratio of solution of rape root disease prevention by the three-factors, which was sowing time(X1)= Oct.10^st or Oct.11^st; boroncalcium ratio(X2)=26.85; potassium fertilizer(X3) =8.37 g/m^2. |
