| 摘 要： | 采用单因素随机区组设计,于冬小麦不同生育期取样,测定各器官干物质积累量。结果表明,各处理小麦总干物质积累基本呈"S型"变化趋势,离滴管带越近的冬麦,干物质积累越多,且1管4行总干物质积累高于1管5行处理。1管5行边3行花后光合能力最弱,干物质积累最少,总干物质运转主要在花前,其余4个处理则相反,干物质主要靠花后积累。各处理小麦总的干物质在不同器官间的分配比例基本一致,均为籽粒最高。不同处理对主茎产量性状影响不大,对分蘖穗产量性状影响较大,达显著或极显著水平。

| Abstract: | 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. |
