摘　　要：工厂化水培生菜立体错位栽培系统是在不影响生菜光照的基础上,兼顾提高单位面积栽培株数而发展起来的一种生菜栽培方法.为提高该系统机械化率、降低劳动强度,针对立体错位栽培架特点,提出了在定植盘推入前将定植杯抬起一定高度,使定植杯跨过栽培槽堵头,再将定植盘推上栽培槽的方法,并开发出一套定植盘搬运装置.以生菜定植盘为试验对象,采用Box-Behnken试验设计方法探究影响搬运装置上盘成功率的因素,并寻求最优参数组合,试验结果表明:当栽培槽水平安装误差为0~5 mm、导向板角度为60°、推进速度为0.22 m/s时,上盘成功率达到99.33%,满足工厂化水培生菜立体错位生产需求.The three-dimensional dislocation cultivation system of factory hydroponic lettuce can be developed on the basis of increasing the number of cultivated plants per unit area without affecting the light of lettuce.To improve the mechanization rate of the system and reduce labor intensity,according to the characteristics of the three-dimensional dislocation cultivation,the planting cup was proposed to raise to a certain height before pushing the planting tray,and the colonization cup could cross the cultivation trough plug.The colonization tray was pushed up the cultivation trough,and a set of planting tray handling equipment was developed.Taking the lettuce colonization tray as test object,the Box-Behnken experimental design method was used to explore the factors affecting the success rate of the handling equipment on the plate,and the optimal parameter combination was discussed.The test results show that when the horizontal installation error of the cultivation tank is 0-5 mm with the guide plate angle of 60°and the advancing speed of 0.22 m/s,the largest success rate of the upper plate of 99.33%can be achieved,which can meet the three-dimensional dislocation production requirements of factory hydroponic lettuce.
