套播小麦拔节期主茎或大分蘖幼穗死亡后会出现再生分蘖。合理利用这一特性对减少和挽回灾害损失有重要的补偿作用。但从立足抗灾,高产稳产的栽培策略来看,这是一种被动的抗灾应变管理措施。积极、主动的还是在培育冬前适龄、壮苗、足苗上下功夫,充分、合理地利用拔节前有效低位分蘖优势。 Replanting tillers appeared after the death of the main stem or big tiller in young wheat at jointing stage. The rational use of this feature has an important compensation for the reduction and recovery of disaster losses. However, from a foothold in the disaster, high and stable yield cultivation strategy point of view, this is a passive disaster management measures. Active, active or in training before the age, strong seedlings, seedlings work hard, full and reasonable use of pre-jointing effective low tiller advantage.
