为了培育适应种植制度特点又适应插秧机作业的秧苗，对采用钵苗穴盘、钵形毯状盘、塑料软平盘培育的机插秧秧苗和机插效果进行了比较研究。结果表明，采用钵苗穴盘育秧，具有节省种子，播种精度、出苗率、成苗率高的优点。秧龄为20 d时3种秧苗质量差异小，此后，钵苗穴盘秧苗质量优势逐渐突出。30 d时，3种秧苗插秧质量差异不大；但40 d或更长时间，钵苗穴盘育秧插秧质量好于钵形毯状盘、塑料软平盘育秧，且返青期明显缩短，这更适宜于成都平原稻麦两熟种植制度区域。

In order to cultivate seedlings that are adaptable to farming system and transplanter, the seedling quality and machine transplanting quality of potted-tray, bowl-shaped blanket tray and soft plastic flat plate were compared and analyzed in this paper. The results showed that nursing seedlings with potted-tray had the advantages of saving seeds, high sowing precision, high seedling rate. The quality difference was smallest among the 20-day-old seedlings that were nursed with 3 different patterns, but since then the quality advantage of potted-tray grown seedlings had been more and more prominent. There was small difference in quality among the 30-day-old seedlings. However, for the seedlings that were older than 40 d, the transplanting quality of potted-tray grown seedlings was higher than that of bowl-shaped blanket tray grown seedlings and soft plastic flat plate grown seedlings. In addition, the returning  green period of the potted-tray grown seedlings was significantly shortened. Compared to the bowl-shaped blanket tray grown seedlings and soft plastic flat plate grown seedlings, the potted-tray grown seedlings were more suitable to transplant by machine in the wheat-rice double cropping areas of Chengdu Plain.
