Abstract: The technique of ridge planting and furrow sowing and sprinkling irrigation has obvious effect on the superposition utilization of precipitation and irrigation water, and is suitable for the well irrigation agricultural area in the north. By measuring soil moisture change, soil temperature change, dry matter accumulation and distribution, yield, water use efficiency and benefit under different irrigation treatments, the mechanism and effect of different irrigation treatments on soil moisture and soil temperature and water and heat efficient utilization of oil sunflower are analyzed. The results show that ridge and furrow seeding can reduce evaporation between trees, make full use of winter irrigation water storage and limited irrigation water resources, and improve water use efficiency. Compared with CK（effect of the culture sprinkler irrigation）, the variation range of soil temperature is smaller and more gentle, and the regulation effect of soil moisture and heat is obvious, which improves the utilization efficiency of water and heat, and promotes the formation of oil sunflower yield. The dry matter accumulation of T3（furrow seeding sprinkler irrigation, irrigation quota of 36mm） and T4（furrow seeding sprinkler irrigation, irrigation quota of 42 mm）in ridge and furrow treatment is higher than that in other ridge and furrow treatments and CK treatments, which increases the total photosynthetic products and the accumulation of economic products. Under the condition of suitable irrigation quota（T3）, the oil sunflower yield is 6.1%and 8.3% higher than CK, the water use efficiency is 0.34 and 0.54 kg/m~3 higher than CK, and the net output value is 6.7% and 10.2% higher than CK. In the practice of oil sunflower planting and production, it is suggested that the irrigation quota should be 28 mm, and the irrigation frequency should be kept at 3～5 times according to the climatic conditions.
