为解决钵苗移栽过程中,因苗钵与苗盘间粘附力导致取苗过程中苗钵破损,进而影响取苗成功率及栽后幼苗长势的问题,对活动苗盘开启脱苗时苗钵和苗盘侧板进行受力分析并对苗钵与侧板间粘附力影响因素进行研究.发现苗钵粘附力与苗盘开启峰值力之间存在正相关关系,苗盘侧板倾角与苗钵粘附力呈负相关关系,苗盘开启部件速度和基质含水率与苗钵粘附力呈正相关关系.为进一步研究各因素对苗钵粘附力的影响规律,以苗盘开启峰值力表征苗钵粘附力作为优化指标,以苗盘侧板倾角、苗盘开启部件速度和基质含水率为试验因素,利用响应曲面方法进行优化试验设计,同时测算各试验组合中苗钵基质损失率.当苗盘侧板倾角为...

In order to solve the problem that adhesion force between the seedling pot and the seedling tray caused the damage in seedling pot in the process of seedling transplantation, and further affected the success rate of picking seedling and the growth of seedling after transplantation, the force analysis of the seedling pot and the side plate in the opening process of movable tray was carried out. It was found that there was a positive correlation between adhesion force and opening peak force of the movable tray, a negative correlation between the ...
