Timely topdressing should firstly apply the fertilizer and pre-flower fertilizer in time to promote the early growth of the plant, form a new leaf area as soon as possible, increase the effective number of flowers, and increase the fruit setting rate. Due to the shallow root system of strawberry, it is sensitive to the reaction of fertilizer. To avoid the application of fertilizers such as ammonium bicarbonate and ammonium sulfate, urea and compound fertilizer should be used. In addition, in the flowering result period, the spraying of 2 to 3 times of potassium dihydrogen phosphate solution on the foliar surface can improve the quality and the yield increasing effect is remarkable. Prevention and control of pests and diseases on leaf spot, gray mold, verticillium wilt, blight, powdery mildew and other fungal diseases can be sprayed in early spring using Bordeaux mixture, Daisen zinc, methyl thiophanate and other drugs, especially Control the disease at the initial stage. The virus disease is mainly caused by aphids with poison, and it is necessary to control aphids. For underground pests such as tigers, crickets, and scorpions, 1000-1500 times of sulphur solution can be used for watering and poisoning; for locusts, dimethoate and trichlorfon can be used. Such as prevention and control; for spider mites, it is possible to use triclosan, ketone and the like to spray. Disclaimer: Some articles on this website are transferred from the Internet.

In the middle of the ploughing, the strawberry should be cultivated in a timely manner to weed and loosen the soil to promote the growth and development of the strawberry and prevent grass damage. The cultivating should be shallow, so as not to hurt the roots and prevent the clods from pressing the seedlings. At the same time, it is necessary to combine with the clear ditch to prevent waterlogging and hinder the normal growth of strawberries.
After cutting off the growth of the old leaves, the dried old leaves and diseased leaves are cut off in time to improve the ventilation and light transmission performance of the plants and reduce the humidity in the field. The removed residual leaves should be taken out of the field and concentrated to build fertilizer to prevent infection.
Reasonable water management is generally watered before the bud, and the fruit is expanded to maturity. The water should be supplied in time according to the dry and wet conditions in the field. Every time the amount of irrigation should be appropriate, avoid flooding. Too much water content in the soil and poor air permeability will directly affect the growth and development of the root system. The surface moisture is too large and the disease is easy to breed. Especially in the fruit ripening period, excessive irrigation or rainy season, it is easy to rotten fruit. Therefore, drainage work should be done after irrigation and during the rainy season.

Uncovering the film and smelting the seedlings with the increase of the temperature after the spring, the wintering cover should be gradually removed. When the average temperature is stable at around 10 °C, it will be sprinkled and will be removed by mid-March. If the film is covered with cold, it is necessary to do a good job of refining the film after the film is uncovered, to prevent sudden changes in the temperature environment, and to make the temperature difference too large and affect the growth and development of the strawberry.
