Strengthening the management of strawberries in the spring is the key to promoting quality, early maturing and increased production. Specific measures to grasp the "five timely": 1, timely removal of cold cover. Strawberries are temperate and evergreen plants. When the soil temperature is between 1Â°C and 2Â°C, the root system begins to grow. In production, generally when the temperature is around 5Â°C, it is necessary to remove the winter-proof and cold-proof materials in time, pick up the leaves and other sundries, and use a film-covered strawberry. After the film is uncovered, the work of hardening the seedlings must be done to prevent freezing in the early spring. 2, timely loose soil, thinning. After cultivating in spring, timely cultivating loose soil and increasing soil temperature, cultivator should be shallow and not deep enough to prevent the soil blocks from pressing down seedlings. At the same time, it is necessary to do a good job of seedlings and to remove the smoked side vines early. 3, timely fertilization. After the beginning of spring, the temperature is getting higher and the plants begin to grow. Applying fertilizer in time can increase the number of effective flowers and increase the fruit setting rate. As strawberry roots are shallow and sensitive to fertilizers, fertilization should be based on urea and compound fertilizers. The amount of fertilizer should not be too large. Generally, the application of urea from 5 kg to 6 kg and compound fertilizer from 10 kg to 15 kg are appropriate. In addition, the 0.2% potassium dihydrogen phosphate solution was used as a foliar dressing during the flowering period, which has a good effect on improving quality and increasing yield. 4, timely sparse flowers and thinning fruit. Inflorescences on the fresh stems of strawberry usually have 10 to 30 flowers; buds consume excessive nutrients, plant growth is weak, and small fruits and deformed fruits increase. Therefore, it is necessary to carry out sparse fruit thinning in time so that 2 to 3 inflorescences per plant can be retained, and 3 to 5 can be left per fruit inflorescence. 5, timely control of pests and diseases. The diseases that damage strawberries mainly include leaf spot, gray mold, powdery mildew, bud blight, and viral diseases; insect pests include aphids, underground pests, and red spiders, etc. The production must be strengthened in terms of forecasting, discovery, and timely prevention and treatment.
