| 摘 要： | 在分析以往高产典型及山东小麦高产途径演变的基础上,提出一条稳住叶面积系数、控制株型增穗数的小麦高产栽培新途径。并对运用该途径实现单产超过9 t/hm2的麦田进行分析,该途径通过先控后促的肥水运筹和通过减少单株叶面积增加单位面积成穗数等措施建立起大密度-小株型的群体结构,该结构在提高收获指数和粒叶比方面有明显的优势,且有助于促进源库流在高水平上协调与平衡,从而可实现产量上的突破。同时还为小麦高产育种和高产栽培研究提供了参考。

| Abstract: | The article advances a new high-yield way for wheat of stabilizing LAI-controlling plant type and increasing ear numbers on the basis of analyzing the previous high-yield ways.After analyzing the fields of which the wheat yield is more than 9 t/ha according to the new way,it pointed out that the new way build a high density and small plant structure by first controlling and then increasing the fertilizer and water,reducing the leaf area of every plant to increase the ear numbers of unit area and other measures,the structure has great advantages in increasing harvest index and rate of gain to leaf,and helped to improve the Coordination and balance of source-sink-translocation in a high level,therefore,it can make a breakthrough in the aspect of the yield and throw light on the high-yield breeding and growing of wheat. |
