Strengthen management, details are as follows:
Key points of breeding
1. Watering and fertilization: The capacity of the flowerpot is limited, and the nutritional area and water storage are not much. Water and topdress in time. Watering should depend on the season. In early spring and late autumn, watering should be done after 4 o'clock in the afternoon. Strawberries like a humid environment. In terms of management, they should be watered frequently to keep the soil moist. During the fruit growth and maturity stages, that is, in April and May, the water demand is large, so watering should be frequent, but there should be no stagnant water to prevent root rot. Fertilizer directly affects the growth and results of potted plants. Before germination in spring, nitrogen fertilizer is the main fertilizer, for example, 0.1%-0.3% urea solution can be sprayed 2-3 times; before flower buds differentiate, phosphorus and potassium fertilizers are mainly used, and 0.2% potassium dihydrogen phosphate aqueous solution can be sprayed 1-3 times. 2 times, to promote flower bud differentiation and fruit growth, and reduce the formation of ineffective flowers; after picking the fruit, use nitrogen, phosphorus and potassium compound fertilizer as the main fertilizer to improve the overwintering ability of strawberries. Top dressing should be carried out based on the principle of applying thin fertilizer frequently, on average once a week. Under no circumstances should thick and raw fertilizers be applied.
2. Plastic pruning: Potted strawberries are not allowed to be heavily pruned. Remove excess stolons, old leaves, and diseased leaves in time to reduce nutrient consumption. You can use iron wire or bamboo sticks to make fruit stands of different shapes, and put them into flower pots to stand up the fruit ears. Stolons can also be used to shape according to the principles of bonsai art to improve their ornamental value.
3. Pest and disease control: Potted strawberry pests and diseases generally occur less or less frequently. Aphids are the main spreaders of strawberry virus. You can use imidacloprid or 1:200 washing powder and water plus a few drops of vegetable oil, mix thoroughly and then spray.
4. Overwintering and cold protection: Move potted strawberries indoors in October, or place them on a sunny enclosed balcony to prevent frost damage and affect the growth and development of strawberries.
5. Change the pot: Since the nutrients in the culture soil will be washed out during frequent watering, after 2-3 years, the nutrients in the culture soil will be seriously lacking, and it is necessary to change the pot in time. pot. Stop watering before pouring the pot to allow the soil to shrink and separate from the pot wall so that the culture soil can be poured out. After the soil ball is turned upside down, cut off the 2-3 cm thick old roots around the culture soil, mix the organic fertilizer with the soil, sieve and fill the bottom. Then put the soil ball in the pot, fill it with fertilizer around it, and water it once to make it watery.
