The root distribution of strawberry is shallow. The irrigation and fertilization should focus on the flowering period and fruit expansion period. The nitrogen, phosphorus and potassium should be properly combined and carried out in small amounts. For open field strawberry, it is recommended to combine irrigation, apply urea and potassium sulfate per acre during flowering period, or apply high nitrogen and potassium compound fertilizer with total nitrogen, phosphorus and potassium nutrients not less than 45%; during fruit expansion period, spray Shixin high-fat membrane combined with rapeseed Zhuang Tingling enhances nutrient flow, promotes fruit development and expansion, enhances strawberry water absorption and absorption, and improves fruit yield and quality. For the protection of strawberries in greenhouses, it is necessary to adhere to the principle of “small number of timesâ€, and combine topdressing with irrigation. The specific quantity and number depends on soil fertility, soil moisture and plant growth and development. It is necessary to focus on the flowering period and the fruit expansion period. The fertilizer is mainly composed of potassium sulfate compound fertilizer. Each time, the high nitrogen and potassium type ternary compound fertilizer is applied for 15-20 kg, and the top dressing is stopped 15 to 20 days before the pulling.
