摘　　要：为探明毯苗插秧机增加取秧块面积的改进技术以及在该技术下稀播长秧龄的水稻适宜播量、秧龄和育秧盘,并形成毯苗机插稻稀播长秧龄农机与农艺相配套技术。结果表明,经过对毯苗插秧机性能的改进,增大取秧面积,毯苗机插杂交稻可实现与钵苗机插稻相当的产量,同时常规稻产量比未改进的常规毯苗机插稻增产4.74%~6.83%;机插水稻秧龄在30 d内,秧龄和产量成正相关关系,播量80 g/盘、秧龄30 d的处理产量最高;与普通塑料盘相比,大体钵型毯状降解盘透水透气性好,栽插带土成球,秧苗素质好,植伤轻,水稻缓苗期短。In order to find out the improved technology for increasing the area of taking seedling for blanket seedling transplanter and the suitable seeding amount, seedling age and seedling raising trays for the long seedling age under this technology, and to form the matching technology of agricultural machinery and agronomy for the long seedling age with blanket seedling machine transplanting.The results showed that compared with pot seedling transplanting rice, with the improved technology, the yield of hybrid rice was basi-cally equivalent, while the yield of conventional rice could be increased by 4.74%~6.83%. When the seedling age of machine-trans-planted within 30 days, the seedling age and yield have a positive correlation. When the sowing rate reached 80 g/plate, the rice yield was the highest when the seedling age reached 30 days. Compared with ordinary plastic trays, the large bowl-shaped carpet degrad-able tray have better water permeability and air permeability, the seedling roots carrying soil, the seedlings have better quality and lighter injury, and the slow seedling period of rice was shorter.
