摘要
为了实现水稻的高产丰收，采用苯板隔寒、稻壳隔寒与常规育苗3种育苗方式对晚熟品种松粳9号进行育苗试验，研究隔寒增温对水稻育苗的影响。结果表明：水稻苗床隔寒增温早播高产栽培技术可以延长水稻营养生长期，促进植株提前成熟15d左右，争抢有效积温200℃左右，产量增加13．3％～19．5％，充分发挥了水稻晚熟品种的增产潜力，成为寒地稻作区高产稳产的重要途径。
In order to nealize high yield of rice, seedling test of Songjing 9 was implemented by polystyrene board and rice husk insulation against cold and routine breeding, the effects of isolating cold and warming methods on rice seedling were studied. The results showed that the seedling cultivation technique with isolating cold and warming methods could not only extend the vegetative stage of rice and promote earlier maturity for 15 days, but also compete effective temperature about 200℃ and yield by increased 13.3%-19.5%. This technique exerted the yield potential fully in late-maturing varieties,and became a important way for high and dependable yield in cold area.
