Study On Dynamics of Accumulation and Distribution of Dry Matter of Wheat Bainong64
Gao Qinglu et al. (Henan Vocation- Technical Teachers′College,Xinxiang45 30 0 3)
The growth of dry matter weight of wheat Bainong6 4expressed a"S"curve;the dis- tributed centre of dry matter were stem,leaf and other nutritorium before earing and ear be- came the centre after earing.Based on these results,the writer suggested that full basic fer- tizer should be applied before sowing and topdressing should be applied in the early period to guarantee wheat plant to build nutritorium successfully.Suitable topdressing about earing could prolong the life of founction leave,and promote the form of photosynthate,the accum- lation of photosynthate in the ear,and increase the yield of wheat Bainong6 4.
