The invention discloses a culture method for paddy-upland rotation of strawberries and water chestnuts to eliminate successive cropping obstacles. The method comprises the following steps: in the first ten-day period of March, building ridges at the periphery of a plastic film coated sunlight warm greenhouse, taking an organic fertilizer as a base fertilizer, feeding water for ploughing and levelling to obtain a shallow water chestnut nursery pond; harvesting the strawberries, and ploughing and levelling a piece of field to obtain a flat rectangular piece of field; setting shallow water chestnuts 45 days after the shallow water chestnuts are sowed generally, transplanting the shallow water chestnuts to the prepared strawberry field, and inserting the shallow water chestnuts into soil for setting; and harvesting water chestnut stems and water chestnuts, applying an organic fertilizer or fermented farmyard manure serving as a base fertilizer, ploughing and ridging, transplanting strawberry seedlings, performing normal field management, and harvesting the strawberries. Facility strawberries are taken as an agricultural production main body, the water chestnuts are auxiliarily planted, the paddy-upland rotation is realized, successive cropping obstacles such as soil acidification and salinification, nutrient imbalance and serious soil-borne diseases and pests caused by successive plantation of strawberries in the facility strawberry field are delayed or eliminated, the utilization rate is improved, the shopping baskets of consumers are enriched, and the agricultural production benefit is further improved.
