摘　　要：为提高番茄钵苗机械化移栽效率,以链式纸钵苗高速、有序、有效栽植为目标,设计一种分离辊角度可调差速式番茄链式纸钵苗移栽试验台。采用二次正交旋转中心组合试验,选取作业速度、开沟器入土深度和覆土镇压器夹角为影响因素,以钵苗直立度合格率和株距变异系数为评价指标,通过土槽移栽试验,研究栽植机构结构与作业参数对栽植机构作业质量影响。结果表明,作业速度0.6~0.68 m·s-1,开沟深度103~116 mm,覆土镇压器夹角为40°时,番茄钵苗移栽直立度合格率大于90%,株距变异系数小于10%,满足番茄钵苗移栽技术要求,为番茄链式纸钵苗移栽机研发提供参考。In order to further improve the seedling planting quality and efficiency of tomato transplanting machine,the work parameters of planting apparatus of tomato transplanting machine should be analyzed.So angle-adjustable and differential type tomato chain paper pot transplanting testbed has been designed aiming at high speed,orderly,effective planting of the chain paper pot.The orthogonal rotation combination test was conducted to study the planting organizational structures and work parameters effect on its operation quality,which took forward velocity,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 indexes.By using design-expert regression analysis method and response surface method,the effects of three factors on test indices were analyzed.The results indicated that with the parameters of forward velocity were 0.6-0.68 m·s-1,backfill shovel inclined angle were 40°and the depth into the soil of furrow opener were 103-116 mm,the percent of pass of upright degree was higher than 90%,the coefficient of spacing deviation was less than 10%.All the indices were better than standard values.The optimized parameters can meet the technical requirements of tomato transplanting mechanical performance,which will provide reference for further research.
