摘 要:对烟草钵苗的基本几何特征参数进行测定,得出其几何分布规律及变化区间;通过单因素试验,在自主研制的YZ-2型烤烟移栽复式作业机上研究了钵苗栽植器移栽时牵引速度和钵苗高度对相同土壤含水率钵苗移栽质量(钵苗移栽直立度和株距变异系数)的影响。结果表明:移栽过程中,牵引速度对钵苗移栽直立度影响显著(α=0.05),对株距变异系数影响不显著。当钵苗高度<18cm时,钵苗移栽直立度及株距变异系数均呈平稳变化趋势;当钵苗高度>18cm时,直立度呈降低趋势,但影响不显著。研究结果可为烟草钵苗移栽部件的设计提供依据。In this paper , some basic geometric parameters of tobacco seedling were measured , and their geometric distri-bution and variation section were concluded .Through single factor experiment with the home-grown YZ-2 flue-cured to-bacco transplanting machine , effects of traction speed and the potted-seedling height were studied on potted-seedling transplanting quality ( upright degree and spacing variation coefficient of potted-seedling ) under the same soil moisture content .Results show that during transplanting , traction speed has significant effect on upright degree (α=0 .05 ) , while no significant effect on spacing variation coefficient .When the potted-seedling height is less than 18cm, the change trends of upright degree and spacing variation coefficient of potted-seedling transplanting are both stable .When the pot-ted-seedling height is over 18cm, the upright degree has decreasing trend , but the impact is not significant .The results provide a basis for designing transplanting parts of tobacco potted-seedling .
