| 摘 要： | 针对大规模寒地水稻芽种生产中,浸种、破胸、催芽3个环节存在的上下层水温不均匀、浸种箱内稻种有氧呼吸差,易导致种子"出芽率低"甚至发生"烧种"、"烂芽"等问题,研究了浸泡温度、时间对水稻种子生理活性的激发机理,构建了基于物联网技术的温度、湿度、氧气监控体系,研发了程控水稻催芽系统,实现浸种箱内催芽环境分段式自动化管理。通过对浸种箱内温度场模拟及大田生产试验证明:系统温、湿、氧调控准确度高,均匀性好,水温控制精度?0.2℃,水位控制精度?0.3%,种子发芽率达97.79%,箱内不同区域芽种出芽率相差1%以内,芽种整齐度、健壮程度大幅提高。该系统研究为寒地水稻生产水平的提高提供了技术支撑,体现了较好的社会经济效益。
