Abstract: There are so many climatic potentials to increase the yield of spring wheat in cold-cool irrigating area of He-Xi, such as sufficient light, suitable temperature, light in tuna with temperture, relatively concentraed rainfall and moderate effective wind speed. We are sure that it must be another higher yield area of wheat in our country. Analysis shows that the climatic factors which limit the development of productive potential for spring wheat are drought in tillering-jointing stage and lack of sunshine in blooming and milkfilling stages. Some ways to develop the climatic potential in this district are discussed.
