Abstract: Since 1990, the development of high productive cropland has been accelerated and the effect of its yieldand benefit increase is very obvious,But,whether high yield and high efficiency can be synchronized de-serves close attention,In this research,79 high yield cropping patterns are investigated for three years inHubei and their efficiencies are analyzed.Countermeasures for existing problems are put forward.
