Dynamic Change of Dry Matter Accumulation and Distribution of Winter Wheat under Different Distance to Drip Tape

In this introduction experiment,the change of dry matter accumulation,partition and yield of wheat under different distance to drip tape was studied to direct the industral production of wheat.The one factors of exercise at five levels orthogonal design were used,and the dry matter of different plant organ was measured in different growth stage of wheat.The researching results showed that:The total dry matter accumulation and leaf and stem dry matter accumulation showed a S curve.Away from the dropper with the more recent accumulation of dry matter,and an overall dry matter accumulation of six drips more than five drips processing.A third line of the five drips while the weakest photosynthetic capacity after flowering and dry matter accumulation at least,operating mainly in the total dry matter before flowering,and the remaining four treatments on the contrary.The partition of total dry matter in different organs showed similar trend.Yield of different treatments on the main stem has little effect on the tiller spike greater impact on yield traits,reaching significant or highly significant.
