Cultivation methods and precautions for crabapple
As one of the famous traditional flowers in China, Begonia is deeply loved by gardening enthusiasts for its colorful flowers. Mastering scientific breeding methods can make crabapple plants strong and have a lasting flowering period. This article will analyze the five core points from environmental control to daily maintenance systems. Environmental control factor temperature management The optimal growth temperature of crabapple is maintained at 15-22℃, and the temperature difference between day and night needs to be controlled within 5℃. Shade measures should be taken when the high temperature exceeds 24 ° C in summer, and the temperature should be kept no lower than 10 ° C in winter. In the northern region, it is recommended to use greenhouses to overwinter to avoid low-temperature freezing damage. Light demand Direct light for 6 hours a day is required in spring and autumn, and 30%-40% of the light is required during high temperature periods in summer. Gradually increase the light duration after October, and newly transplanted plants need to grow in a cool place for 2 weeks. Rotate the flowerpot regularly to ensure uniform light reception. Daily maintenance skills Scientific watering adopts the principle of "seeing dry, seeing wet", and water is poured thoroughly after 2 cm of the surface of the basin soil is dry. The air humidity needs to be maintained at 60%-70%. Spray and humidification can be carried out regularly but avoid leaf area water. Control water to soil micro-tide state in winter. It is recommended to use a mixed substrate of peat soil: perlite: humus soil =5:3:2 for soil formulation, and add bone meal as base fertilizer every two years when changing pots. A 3cm ceramite drainage layer needs to be laid on the bottom of the basin to ensure root oxygen permeability. Fertilization management Apply 1:1000 diluted nitrogen-phosphorus-potassium balanced liquid fertilizer every 15 days during the growth period, and increase phosphorus and potassium fertilizer during the budding period. It is recommended to use special slow-release fertilizer for Haitang and supplement trace element foliar fertilizer every quarter. Special precautions 1. Newly purchased plants need to be isolated and observed for 2 weeks to prevent pests and diseases 2. Trim residual flowers in time after flowering and supplement organic fertilizer 3. Regularly check common insect pests such as red spiders and aphids 4. In the rainy season, drainage needs to be strengthened to prevent root rot. In the northern heating season, it needs to be used in conjunction with humidifiers. By accurately controlling temperature and humidity, reasonably mixing cultivation substrates, and implementing periodic maintenance, crabapple can continue to bloom for many years. It is recommended to dynamically adjust the maintenance plan based on the growth status of the plant and record the growth logs regularly to help grasp its growth laws.
