Abstract: To study effect of high light efficiency fallow rotation corn on soil environment technology，combined with two methods of physical and chemical research in this agricultural technique，several important changes in the soil environment index were analyzed.Results showed that this technique corn farming fallow rotation high luminous efficiency technology had significant implications to protect soil，would bring huge economic，social and ecological benefits for agriculture.This technology could promote good soil structure，high light transmittance，get to play a marginal effect，fallow rotation，and effectively protect soil organic matter.While it could reduce operating procedures，significantly reduce operating costs and enhance ability of soil moisture conservation，soil moisture than traditional ridge beneath higher.Under high light efficiency fallow crop rotation，soil agricultural resources have been effectively protected.
