The invention discloses a double-trench close planting water and fertilizer integrated Chinese yam cultivation method. A double-trench planting mode is adopted, the width of each unit is 1.2m, and twoplanting trenches are formed in each unit, so that the length of the planting trench per mu reaches about 1100m. Compared with the traditional single trench planting that the planting trench length only reaches 740m, the double-trench close planting method has the advantages that the planting trench length of about 360m is increased, a planting row spacing of 0.2m is less than the traditional planting row spacing of about 0.25m, and the planting density is increased. Then, the yield per plant of Chinese yam is about 80% of the yield per plant during single trench planting, the yield per mu isabout 130% of the yield per mu during single trench planting, water is directly supplied to the Chinese yam root through a dropper, the water usage amount can be reduced, and the evaporation capacityof surface water can be reduced, so that the water-saving planting aim is achieved.
