中文摘要:
      针对穴盘苗脱盘过程中基质损失导致取苗成功率降低的问题,以活动苗盘所育油菜钵苗为研究对象,选取苗盘锥角角度(7°、9°、11°)、基质压实度(1.0、1.1、1.2)、基质含水率(55%、60%、66%)为试验因素,以苗钵基质损失率为试验指标值,进行正交试验,研究苗钵脱盘过程中各因素对苗钵基质损失率的影响。结果表明:穴盘苗脱盘过程中,苗钵基质平均损失率为3.09%;苗盘锥角角度和基质压实度对基质损失率的影响极显著,基质含水率对基质损失率的影响显著;各因素对苗钵基质损失率影响大小依次为基质压实度、苗盘锥角角度、基质含水率;当苗盘锥角角度为11°、基质压实度为1.2、基质含水率为66%时,苗钵基质损失率最小,为2.62%。
英文摘要:
      In order to solve the problem that the success rate of pot seedling picking decreased due to the matrix loss in the process of the seedling detaching from the tray, orthogonal tests were carried out to study the influence of the cone angle of seedling tray(7°, 9°, 11°), compaction degree of matrix(1.0, 1.1, 1.2) and the moisture content of matrix(55%, 60%, 66%) on matrix loss rate of pot seedling during the process of pot seedling detaching from the movable tray. The test results showed that the average matrix loss rate was 3.09% in the process of pot seedling detaching from the movable tray. The influence of experimental factors on the matrix loss rate were the compaction degree of matrix, the cone angle of seedling tray and the moisture content of matrix from large to small. The optimal combination of experimental factors was as follow: the cone angle of seedling tray was 11°, the compaction degree of matrix was 1.2 and the moisture content of matrix was 66%, which achieved the lowest matrix loss rate of 2.62% in the process of pot seedling detaching from the movable tray.
