The solution of Cu2+、Mg2+、Zn2+、Ca2+ and their mixture are used to maintain the green of winter wheat juice.

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.

Results indicated that the soil of winter wheat field in the rapid growth season is a weak sink of CH_(4).

Membrane side winter wheat cultivation technique is one new technology,have extremely notable increasing yield,protect water, increase temperature effect,the research has the certain theory and real effect,The results show that beside membrane soil moisture increas- ing 9.

Effect of and sowing time, types of soil and variety on yield components of winter wheat sowings in spring;
