中文摘要:
      倒春寒是目前影响黄淮麦区冬小麦稳产高产的主要障碍因子之一,它影响小麦的生长发育,进而降低产量和品质。本文基于当前研究现状,从倒春寒对小麦细胞膜系统、光合作用、呼吸作用、活性氧代谢、渗透调节物质、内源激素代谢等方面的危害机理进行了回顾和综述。同时也从选育耐寒品种,搞好品种布局、水肥管理、应用外源化调物质等方面综述了当前倒春寒的栽培防控措施。建议在今后的小麦倒春寒研究中,应综合考虑多重逆境叠加的影响,并充分利用CRISPR技术、高通量表型平台等最新的技术和平台来深入研究倒春寒的致灾机理和响应机制、小麦对倒春寒响应的敏感时段与耐性范围以及灾害的防控指标,在此基础上研发减灾保产的关键技术体系,确保我国小麦的绿色丰产与粮食安全。
英文摘要:
      Late spring coldness is one of the most important hinderance factors for high and stable yields of winter wheat in Huanghuai areas through the effects on the growth and development of wheat, thereby reducing yield and quality. Based on the current research situation, the damage mechanism of late spring coldness on wheat cell membrane system, photosynthesis, respiration, active oxygen metabolism, osmotic regulators, endogenous hormone metabolism and other aspects were reviewed and summarized in this review. Additionally, the currently cultivation and control measures of late spring coldness were summarized in terms of breeding cold-tolerant varieties, improving variety distribution, water and fertilizer management, and applying exogenous chemicals. It is suggested in the future research of wheat spring chill inversion, and the effects of multiple adversities should be considered comprehensively. The latest technologies and platforms of CRISPR technology and high throughput phenotype platform should fully utilized to further study the disaster-causing mechanism and response mechanism of late spring coldness, sensitive period of wheat response to late spring coldness, and control indicators of tolerance range and disaster prevention. On this basis, the key technology system of disaster reduction and yield protection is developed to ensure the green high yield and food security of wheat in China.
