The invention discloses a breeding method for increasing panicum miliaceum yield in a short-day condition. The breeding method includes: increasing field illumination and illumination duration duringgrowing of panicum miliaceum, wherein increasing of the illumination duration refers to increasing illumination to 18h in each day, and increasing of field illumination refers to prolonging the illumination duration to 25d; applying base fertilizer only one time before seeding, wherein the base fertilizer comprises 100kg/hm2 of pure N, 80kg/hm2 of P2O5 and 80kg/hm2 of K2O. By the method, nutritional growth period of panicum miliaceum is prolonged effectively, agronomic characters like plant height, ear length and ear grain weight and yield of panicum miliaceum are improved, and the problem ofrestriction on low breeding yield of panicum miliaceum in Hainan Island in winter is solved. 本发明公开了一种短日照条件下提高糜子产量的育种方法，包括：在糜子的生长期增加田间光照和延长光照长度，其中延长光照长度为每天增加光照至18h，增加田间光照为延长光照长度的持续时间为25天，同时在播种前一次性施用基肥，所述的基肥包括：纯N 100kg/hm，PO80kg
