通过育苗移栽技术可大幅度提高单产，为进一步改善钵苗移栽机的栽植质量。该文以玉米纸钵苗移栽机圆盘式栽植机构为研究对象，利用土槽试验，分析了圆盘式栽植机构的工作参数，研究了栽植机构工作参数对移栽质量的影响规律。采用正交旋转组合试验，以开沟器位置、开沟器入土深度、回土铲夹角为影响因子，以直立度合格率和株距变异系数为响应函数，利用Design-expert软件平台的回归分析法及响应面分析法，对3个因子进行单因素和多因素正交试验。试验表明：当开沟器位置在50 mm、回土铲夹角在40°、开沟器入土深度在115 mm条件下，钵苗直立度合格率能达到93%以上，株距变异系数小于12%。优化后的参数可满足玉米移栽的性能要求，为进一步研究提供依据。
通過育苗移栽技術可大幅度提高單產，為進一步改善缽苗移栽機的栽植質量。該文以玉米紙缽苗移栽機圓盤式栽植機構為研究對象，利用土槽試驗，分析瞭圓盤式栽植機構的工作參數，研究瞭栽植機構工作參數對移栽質量的影響規律。採用正交鏇轉組閤試驗，以開溝器位置、開溝器入土深度、迴土鏟夾角為影響因子，以直立度閤格率和株距變異繫數為響應函數，利用Design-expert軟件平檯的迴歸分析法及響應麵分析法，對3箇因子進行單因素和多因素正交試驗。試驗錶明：噹開溝器位置在50 mm、迴土鏟夾角在40°、開溝器入土深度在115 mm條件下，缽苗直立度閤格率能達到93%以上，株距變異繫數小于12%。優化後的參數可滿足玉米移栽的性能要求，為進一步研究提供依據。

Seedling transplanting technologies can greatly improve crop yield, in order to further improve the seedling planting quality of transplanting machine, the working parameters of disc type planting apparatus of corn transplanter were analyzed, the influence law of working parameters on the plant quality was studied through soil-bin test. The orthogonal rotation combination test was conducted, which took location of furrow opener, the depth into the soil of furrow opener and backfill shovel inclined angle as input variables, and took upright degree and coefficient of variation of row spacing as response. By using Design-expert regression analysis method and response surface method, the effects of three factors on test indexes were analyzed. The results indicated that with the parameters of furrow opener position was 50 mm, backfill shovel inclined angle was 40°and the depth into the soil of furrow opener was 115 mm, the percent of pass of upright degree was higher than 93%, the coefficient of spacing deviation was less than 12%. The optimized parameters can meet the need of corn transplanting mechanical performance and provide basis for further research.
