Cultivation methods and precautions for flower peony
As a classic camellia variety with both ornamental value and difficulty in planting, flower peony has captured the hearts of countless flower growers with its elegant and luxurious flower appearance. If this "queen of flowers" wants to continue to bloom, it is crucial to master scientific maintenance methods. This article will systematically explain the key points of cultivating flower peony from environmental control to disease prevention and control. The three factors of environmental control and temperature accurately control the flower-controlling peony to be native in warm mountainous areas, and the optimal growth temperature is stable in the range of 20-32℃. When the temperature exceeds 35 ° C, it is recommended to protect the leaves by spraying cooling. Although cold-resistant varieties can tolerate low temperatures of-8℃, they still need to maintain environmental temperatures above 5℃ through winter. Scientific lighting ratio ensures more than 5 hours of soft light every day, and 50% sunshade net is used to filter strong light in midsummer. Full sunshine can be accepted in autumn and winter to promote flower bud differentiation. Rotate the flowerpot regularly so that the plants receive even light. Air circulation management keeps the planting environment well ventilated and avoids diseases caused by confined spaces. During indoor maintenance in winter in the north, you can open windows for ventilation at noon on sunny days for 1-2 hours. Advanced skills for water and fertilizer management The intelligent watering plan adopts the principle of "seeing dry and wet". Water is poured thoroughly every 3 days in spring and autumn, and water is replenished once in the morning and evening in summer. Use rainwater or tap water that has been left standing for 2 days, and the water temperature needs to be close to the soil temperature. Nutrient supply strategy Apply diluted fish intestine fertilizer (1:50) twice a month during the growing period, and apply potassium dihydrogen phosphate solution (800-fold dilution) during the bud appearing period. Stop fertilizer and sleep in winter, and bury bone meal as base fertilizer when changing pots in spring. Cultivation methods and precautions for sculpting and pruning artistic flower peonies in spring to promote flowering. In mid-March, new branches are picked to retain 3-4 true leaves. Remove excessively dense flower buds in time and retain 1-2 main flower buds per branch. In winter, after shaping and pruning fallen leaves, cut off dead and weak branches and cross branches to keep the crown transparent. Apply plant ash to the wound after pruning to prevent bacterial infection. Disease early warning mechanism for integrated pest control and pest control of coal smoke disease was sprayed with 800 times 70% thiophanate methyl solution at the beginning of the disease, and Bordeaux mixture (1:1:200) was sprayed once a week for 3 consecutive weeks. The pest eradication program can be used for nematode control by treating 3% carbofuran granules (20g/m2) mixed with soil. Regularly inspect the back of the leaves and find that red spiders are immediately killed with 1000 times matrine solution.
From soil selection and ratio to flowering management, the maintenance of flower and peony requires meticulous operations. By creating a stable environment of 18-25 ° C, maintaining 60% air humidity, and coordinating phased nutritional supplements, even novices can cultivate high-quality plants with flower diameters exceeding 15cm. Remember the eight-character secret of "applying thin fertilizer diligently, preferring to work rather than waterlogging", so that your flowers and peonies bloom like brocade every year.
