How to Precocious and High-yield Strawberry
Strengthen the management of strawberry in spring and make strawberry grow well, result early, excellent quality, and high yield. The specific management measures are as follows: Uncover the film: When the temperature stabilizes at about 10°C, remove the greenhouse cover and remove it from the middle or late March. . Before the removal, the seedlings should be well-prepared so that the plants can gradually adapt to the external environment so as to avoid excessive temperature difference and affect the normal growth and development of the strawberries. Cultivated drainage: After cultivating, timely cultivating loose soil and weeding shall be performed to promote strawberry growth and eliminate weed damage. The cultivator should be shallow and shallow so as not to damage the root system and excessively heavy soil blocks. At the same time, combined with gully drainage to reduce soil moisture and prevent waterlogging. Cut off the old leaves: After the strawberries begin to grow, we must promptly cut off the dried old leaves and diseased leaves, improve the ventilation and light transmission performance between plants, and reduce the humidity in the field. Cut off the remaining leaves to clear out of the field to reduce the source of disease and prevent the spread of germs. Timely topdressing: Due to the shallow root system of strawberries, the response to fertilizers is more sensitive. Therefore, it is not appropriate to use fertilizers such as ammonium bicarbonate and ammonium sulfate, and urea and compound fertilizers should be used. Fat tree fertilizer in combination with water in the middle and late March topdressing, mu urea 10-15 kg or compound fertilizer 20-30 kg; flower before the flowering in mid-April before the topdressing, mu compound fertilizer 10 kg. In addition, spraying 0.2% potassium dihydrogen phosphate and 0.2% of photosynthetic fertilizer 2 times on the foliar stage resulted in significant yield increase. Reasonable irrigation: Usually watering once before budding, the fruit expands to maturity, and the water supply will be added in time according to the conditions of the field. The amount of irrigation should be appropriate, must not flood irrigation. Especially in the fruit ripening period, excessive watering or stains in the rainy season will not only reduce the fruit's sugar content, but also cause it to be rotten. Therefore, timely drainage after irrigation and during the rainy season will prevent waterlogging. Thinning and thinning fruit: After the budding of the strawberry, the thin buds should be removed in time. Generally, the flower buds are separated from one another in the inflorescence, and when they are easily removed, 20-25% of late weak buds are removed. Prevention and control of pests: fungal diseases such as gray mold, leaf spot, verticillium wilt, bud blight, and powdery mildew, may be selected from the group consisting of quick-acting, green deterrence, thiophanate-methyl, dexamethasone, carbendazim, etc. Pharmacy spraying, spraying once every 5-7 days, once every 2-3 times. In particular, after the onset of the disease, it is necessary to apply the pesticide in time and control the disease at the initial stage. Virus disease is mainly caused by aphid-infected virus. It can be sprayed and killed by 1000 times of 10% imidacloprid. Underground pests such as ground tigers, badgers, and cockroaches can be poisoned by 1000-fold phoxim. Red spiders can be sprayed with Krypton and Ketete. Note: The use of chemical pesticides is prohibited during fruit ripening.
