The area is located at latitude 36 ° 08’N, longitude 100 ° 46’E and elevation of 2,491 meters. It is a basin of the Yellow River valley with a frost-free period of 142.5 days and a sunshine duration of 2,924.9 hours. The average temperature is 6.25 ° C, the accumulated temperature is 2,420.7 ° C, and the annual precipitation is 293.2 mm , The annual evaporation of 1,964.8 mm. Under such conditions, the output of spring wheat in our field has reached over one thousand kilos, and it is the key to do a good job of water and fertilizer measures. First, the fertilization measures Our measures are not too much fertilizer, but focus on the spring wheat growth period of all aspects of application. Basal fertilizer, in addition to the application of 5,000 kg of organic fertilizer per acre, but also the application of urea 15-20 pounds, superphosphate 50 pounds, “5406” 300 kilograms of fertilizer, these three kinds of fertilizer fully mixed spread, machine rake soil or use planter
