The filmed drilling cultivation technique of winter wheat is a new breakthrough technique to win high yield for the dry land wheat and the late sowing wheat,coupled with a complete sowing and filming train planter supporting efficient operations,and increasing output significantly.

The advanced main factor regression analysis was applied to winter wheat s climate analysis in this article, in which the practicality and science character of this method were embodied, eventually it was set that the temperature is the main climate element which affect on winter wheat s regreening and the precipitation is the main climate element which affect on winter wheat s yield.

The favourable seeding-time for drilling winter wheat covered with the plastic film are longer and later than that for conventional winter wheat on open plots.
