【摘要】 据历史资料分析得出:暖冬和冬前积温偏多,造成生育进程提前是加重江苏省三麦冻害的主要原因;栽培技术应用不当。加重了冻害发生程度。主要生产对策有:积极选用耐寒力强的品种,扩大半冬性品种比例,提高三麦的抗冻能力;适当推迟播期,避免因提前拔节造成冻害;科学施肥,调控群个体结构,提高整体抗逆能力。更多还原

【Abstract】 Historic data of temperature and accumulated temperature before winter was analyzed. The results showed that the main reason of freeze injury for wheat in Jiangsu province was warm winter or excessive accumulated temperature before winter,which result in advancing the process of wheat growth and development. Moreover inadequate planting technology could worsen freeze injury. The countermeasures to freeze injury includ- ed:firstly,collecting cold resistant cultivars,improving cold resistant ability of cultivars;secondly,delaying the planting time to avoid advancing joint stage;thirdly,adjusting fertilization and improving population ability of cold resistant ability.更多还原
