2, cultivating cultivator: timely cultivator weeding and loose soil in the spring, should be shallow, so as not to hurt the roots and prevent the clods from pressing down seedlings; cultivator should be combined with the clear channel rake, clean up the drainage ditch, Xianggou, Grooves, gutters, etc., to eliminate waterlogging; after the strawberry grows, it is necessary to timely remove the dried old leaves and diseased leaves, and bring out the stacking fertilizer outside the field to prevent the disease from re-infection. 3. Timely top dressing: In the middle and late March, it is necessary to combine top dressing with watering, applying 10-15 kg of urea per mu or 20-30 kg of compound fertilizer; 10-15 kg of compound fertilizer; In addition, 0.3% potassium dihydrogen phosphate solution is sprayed 2-3 times in the fruiting stage of flowering, which is beneficial to increase the yield and quality. 4. Sparse flowering buds: The flowers that bloom first on the strawberry inflorescence are good, and the fruits are large and mature. Therefore, after budding, the buds should be thinned to reduce nutrient consumption, so that the fruits are large and tidy, mature early and of good quality. Discard 20-25% of late weak buds. 5, cut off the old leaves: After the strawberry begins to grow, we must promptly cut off the dried old leaves and diseased leaves in order to improve the ventilation and light transmission performance between plants and reduce the field temperature. Cut off the remaining leaves to clear out of the field, and concentrate on stacking and fattening, in order to reduce the source of the disease and prevent the spread of germs. 6. Prevention and control of pests: (1) Shallow earthworms in early spring, effectively eradicating eggs and larvae from weeds and soil. (2) Use 200-300 grams of 90% crystal trichlorfon or 200-300 grams of 50% phoxim emulsion per acre, dilute 500-700 times, and then water the roots. (3) For leaf spot, gray mold, bud blight, powdery mildew and other diseases, timely prevention in the early spring, can be used 50% carbendazim or 70% thiophanate 500-800 times spray, virus disease is mainly Infected by aphids, it can be prevented and sprayed with 40% omethoate 800 times as early as possible. It is forbidden to use chemical pesticides during fruit ripening. 7, anti-rotten fruit: Strawberry plants dwarf, the fruit is easy to drape to the ground, causing pollution and rot, both large impact on yield and quality. It can be planted around the plants with hay after flowering so that the fruit does not come into contact with the ground. After the fruit is harvested, the grass will be removed.

How to Manage Spring Strawberry
(1) Uncovering membranes to consolidate seedlings: (1) When the average temperature on the day is stable at around 10°C, coverings that protect against over-wintering should begin to be removed. (2) Take care when exposing to prevent breakage of flower buds. If the agricultural film cover should be exposed during the day, cover it at night, and then gradually remove the film to avoid excessive temperature difference, affecting the normal growth of strawberries; after uncovering the cover, the leaves, diseased leaves, and old leaves should be promptly removed to improve light transmission. Conditions to prevent the occurrence of diseases.
