Cultivation method of rose flowers
As the queen of flowers, rose flowers are very popular among gardening enthusiasts for their colorful flower appearance. However, many people often encounter problems such as less flowering and more diseases during the maintenance process. Only by mastering scientific cultivation methods can the roses keep blooming all year round. Soil formulation and improved high-quality substrate are the foundation for rose growth, and acidic soil with high humus content is recommended (PH 5.5-6.5). Add 30% humus leaf soil to the garden soil to improve air permeability, and mix 20% pine needle soil to adjust the pH value. When changing pots in early spring every year, 1/3 of the core soil is reserved and bone meal is added to enhance fertility. The light and warm water circulation system follows the principle of "morning light and evening water": it receives direct light for 6 hours after sunrise, and uses sunshade nets to filter strong ultraviolet rays at noon in summer. Use the knuckle test method-insert the index finger into the second joint of the soil and pour water thoroughly when it is dry, and use ceramite to lay the bottom to enhance drainage. It is only necessary to maintain micro-tide in the substrate during winter dormancy. During the growth period of nutrient supply rhythm, fish intestine water (1:50 dilution) and potassium dihydrogen phosphate (800 times solution) were used alternately every 10 days. In September, nitrogen and phosphorus and potassium were stopped, and borax solution was sprayed to promote flower bud differentiation. In winter, bury decomposed sheep manure as base fertilizer, and remember to avoid root burning caused by unfermented fertilizer. Advanced techniques for reproduction and cultivation Select semi-lignified branches for tender cuttage, retain 3 bud points and soak them in rooting powder. The rootstock of wild rose was selected for grafting, and the T-type bud grafting method was used to operate during the sap flow period. During the new seedling cultivation stage, transparent plastic bags are used to make a miniature greenhouse to maintain 85% air humidity. The comprehensive pest management plan establishes a preventive killing system: spray stone sulfur mixture in early spring to clear the garden, and hang yellow sticky insect boards before the rainy season. Aphids were found to wash the back of the leaves with detergent water (1:200), and scale insects could be killed with alcohol cotton swabs. Spray garlic extract every week to prevent powdery mildew. Ensuring ventilation and light transmission is the key.
By accurately controlling growth factors, scientifically implementing reproduction techniques, and establishing pest and disease prevention systems, roses can fully demonstrate excellent vitality under different climatic conditions. Remember that observing the state of the plant is more important than the fixed process. When the leaves are bright and the new buds are full, it is the best feedback for your careful maintenance.
