综合有关理论研究并结合超高产实例分析,提出稳叶(LAI)控株(型)增穗途径是现阶段实现小麦超高产的较好途径。沿着这一途径在龙口市进行超高产示范连获成功,既创出国内平原区冬小麦单产最高纪录(667m~2产量731.73kg),又在较大面积上使单产600kg的超高产麦田得到重演。初步看出,根据源流库的协调状况大致可把麦田区分为三大类型。一是受限于流的类型,表现形式是潜在源>潜在库>总流量或潜在库>潜在源>总流量;二是受限于源的类型,表现为潜在库>总流量>潜在源;三是受限于库的类型,表现为潜在源>总流量=潜在库。
Combining the theoretical research and the case analysis of super-high yield, it is proposed that the method of increasing LAI by plant LAI is a better way to achieve super-high yield of wheat at this stage. Following this route, the successful demonstration of super-high yield in Longkou City was successful. It not only achieved the highest record of winter wheat yield (667m ~ 2, 731.73kg) in the domestic plain area, but also achieved the yield of 600kg Repeat. It can be initially seen that the wheat fields can be roughly divided into three types according to the coordination status of source reservoirs. One is limited by the type of stream, which can be either potential source> potential library> total flow or potential library> potential source> total flow; second, subject to source type, expressed as potential pool> total flow> potential source; Third, subject to the type of library, expressed as a potential source> total traffic = potential library.
