【摘要】 在室内对钵苗栽直率的影响因素进行了台架试验。结果表明 ,机组前进速度影响最显著 ,其次为沟深和开沟翼板长度 ;机组前进速度与开沟翼板长度间对钵苗栽直率存在相关性影响 ;在试验条件下机组前进速度Vm≤ 0 .4m/s时 ,钵苗栽直率 ξ≥ 95 %。更多还原

【Abstract】 An experimental study about the effect factor of standing seedling rate has been done in the lab .It showed that the V m is the first factor and the depth of furrow and the length of ditch wing is the second ,and there are relationship which affect seedling erection rate between the V m and the length. With the experiment in lab, the standing seedling rate is higher than 95% when the V m is lower than 0.4 m/s.更多还原
