摘要
利用以往提出的潜在库、潜在源、总流量的计算方法 ,对两年 8块超高产示范田的源流库情况进行了分析 ,初步看出 ,8块超高产示范田的源流库平衡关系分属三种类型。一是潜在源 >潜在库 >总流量 ,是受限于流的类型 ;二是潜在库 >潜在源 >总流量 ,是受限于流的另一类型 ;三是潜在库 >总流量 >潜在源 ,受限于源的类型 ;未出现受限于库的类型。研究还指出了采用“稳叶控株增穗”的技术体系 ,建立起来的“大密度小株型”群体结构在源流库三方面都有一定的优势 ;
Adopting the calculating method on potential sink and source and total translocation, we have analysed the source-translocation-sink situation of the eight-plot superhigh-yield representative fields. The source-translocation-sink balance relations of the fields can belong to the following three types: the type limited to translocation, its form is potential source>potential sink>amount of total translocation, or potential sink >potential source>amount of total translocation ;the type limited to source, is potential sink>amount of total translocation >potential source; the type limited to sink has not been found. The studies also consider it is quite good in soure and sink and translocation that we have established the colony composition of the large density-small plant type by using of the way of stabilizing LAI and controlling plant type and increasing numbers of ears. It is a effective way in achieving the source-translocation-sink coordination and balance on the high level.
