Abstract: Straw is a saving production and adjustment measure of modern agricultural production. It can regulate farmland ecological environment and provide nutrients for plant growth. The purpose of this study was to further explore the effects of straw returning on wheat growth and soil nutrient variations in the context of different soil. Wheat straw as experimental material of the study, it was added to the whitish soil, huangni soil, wushan soil with the 1%, 2%, 5%, than we determined the main index of wheat in 14th , 28th and 42nd day ,and determined the physicochemical properties of soil in forty-second day-pulling out the wheat. The results showed that the wheat height, fresh weight and leaf chlorophyll content decreased with the increase of addition amount of straw, and that, to some extent, straw returning changed the soil physical and chemical properties. The study showed that adding straw inhibited the normal growth of wheat growth in the seedling growth of wheat, and showed different degree of influence in different soil conditions.
