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 fert ilizer 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.

Key words: Wheat, High-yield measures, Stabilizing LAI and controlling plant type and increasing ear numbers, Increasing harvest index, Coordination and balance of source-sink-translocation
