Abstract (English): Aiming at the lack of cultivation techniques for rapeseed after suffering freezing rain disasters, this study systematically analyzed the effects of 16 combined disaster mitigation measures--including removing frozen bolts vs. retaining frozen bolts, different foliar fertilizers, plant growth regulators, and ground topdressing--on the yield and economic benefits of freezing-injured rapeseed through field experiments. The results showed that under the condition of low-temperature freezing rain and snow disasters, the freezing injury plant rate of all 22 rapeseed varieties reached 100%, with an average freezing injury index of 67.16, and the correlation between the freezing injury index and yield was not significant among different rapeseed varieties. There were extremely significant differences in the effects of different disaster mitigation measures on increasing yield and efficiency of freezing-injured rapeseed. The yield of the treatment with retained frozen bolts was extremely significantly higher than that with removed frozen bolts. Compared with the treatment of "retaining frozen bolts + blank control", the treatment of "retaining frozen bolts + Xinmeizhouxing" could extremely significantly increase yield and efficiency, with a yield increase of 415 kg/hm² (an increase rate of 24.9%) and an efficiency increase of 2024 yuan/hm²; the treatment of "retaining frozen bolts + Bihu" could significantly increase yield and efficiency, with a yield increase of 365 kg/hm² (an increase rate of 21.9%) and an efficiency increase of 1624 yuan/hm². Therefore, after rapeseed suffers from freezingrain and snow disasters, the removal of frozen bolts should be avoided, and timely spraying of Xinmeizhouxing or Bihu is the optimal disaster mitigation measure that balances yield and economic benefits. This study provides strong technical support for the post-disaster recovery and production of freezing-injured rapeseed and has important guiding significance for ensuring the safe production of rapeseed.

Abstract (Chinese): 本研究针对油菜遭受冻雨灾害后栽培技术缺乏的问题, 通过田间试验系统分析了摘除冻薹与保留冻薹、 不同叶面肥、植物生长调节剂、地面追肥等16种组合减灾措施对冻害油菜产量与经济效益的影响。结果显示, 低温 冻雨冰雪灾害条件下, 22个油菜品种冻害株率均为100%, 平均冻害指数达67.16, 不同油菜品种冻害指数与产量之 间相关性不显著。不同减灾措施对冻害油菜的增产增效作用存在极显著差异。保留冻薹处理的产量极显著高于 摘除冻薹。与保留冻薹+空白处理相比, 保留冻薹+新美洲星处理能极显著增产增效, 增产415 kg/hm2, 增幅24.9%, 增效2024元/hm2;保留冻薹+碧护处理能显著增产增效, 增产365 kg/hm2, 增幅21.9%, 增效1624元/hm2。因此, 油菜 遭受冻雨冰雪灾害后应避免摘除冻薹, 及时喷施新美洲星或碧护是兼顾产量与经济效益的最优减灾措施。本研究 为油菜冻害灾后复产提供了有力技术支撑, 对保障油菜安全生产具有重要指导意义。.
