摘　　要：经多年规模化集中育秧试验示范,逐步探索出早稻机插中拱双层覆盖保温规模化育秧技术。该技术具有节本减污、高效实用、规模增效等特点,比大棚育秧节本近6000元/667 m^(2),秧田利用率比泥浆竹拱覆盖育秧提高100%,取秧效率提高30%左右,值得在早稻机插规模化育秧中推广应用。After years of large-scale centralized seedling cultivation experiments and demonstrations,a new technology of large-scale seedling raising with double layer covering and thermal insulation in the middle arch of early rice machine transplanting has been gradually explored.The new technology has the characteristics of cost saving and pollution reduction,high efficiency and practicality,and scale efficiency.The new technology could save nearly 6000 yuan per 667 m^(2) compared with the greenhouse seedling cultivation,increase the utilization rate of the seedling field by 100%compared with the mud bamboo arch covering seedling cultivation,and increase the efficiency of seedling collection by about 30%,which is worthy of popularization and application in the large-scale seedling cultivation of early rice mechanical transplanting.
