Four wheat cultivars were used to study the effects of delayed nitrogen topdressing on popula-tion structure, grain yield and photosynthetic characteristics of flag leaves under high-yielding conditions. Theresults showed that the nitrogen topdressing delayed from overwintering-turning green stage (N1) to turninggreen-jointing stage(N2 ) and jointing-booting stage(N3 ) decreased ineffective tiller in spring, retarded the de-cline of green leaf area and chlor…查看全部>>
