稻套麦省工节本、晚茬可争早苗、增产增效。冻害是影响稻套麦高产稳产的重要因素。前人主要侧重稻套麦高产栽培配套技术研究，而对冻害后稻套麦分蘖特性及其合理应用研究较少。本文试图在稻套麦拔节发生冻害后设计恢复肥、镇压（分冻害后、冬前）等试验，探讨稻套麦“扬麦１５ Rice sets of wheat provincial section of the cost, late crop dispute early seedlings, increase production and efficiency. Frost damage is an important factor that affects the high and stable yield of rice wheat. The previous studies mainly focused on the high-yielding cultivation techniques of rice and wheat, while the research on the tillering characteristics of rice and wheat and its rational application were few. This paper attempts to design the recovery of fertilizer after the occurrence of frost damage at the stage of the rice set wheat, after the suppression (freezing injury, before the winter) and other tests to explore the rice sets of wheat "Yang Mai 15
