Cultivation method of grape hyacinth
As a bulbous flower that blooms in early spring, grape hyacinth is very popular among gardening enthusiasts for its unique grape string-shaped ears and blue-and-purple colors. The breeding process includes three major links: ball processing, scientific planting, and fine maintenance. You can master key skills to achieve annual restoration. Analysis of grape hyacinth cultivation system technical points for pretreatment of ball high-quality ball should be filled with balls with a diameter of ≥ 3 cm and no mechanical damage to the skin. When local mold spots are found, use a disinfectant knife to remove the diseased tissue. When immersing in carbendazim solution, ensure that the liquid completely covers the incision. The drying process needs to be protected from light and ventilated. It is recommended to lay it on a bamboo sieve to avoid moisture accumulation. The matrix ratio and container selection use clay pots that need to be soaked in advance to remove fire, and the plastic pots should ensure that there are ≥4 drainage holes at the bottom. The substrate is based on the ratio of leaf soil: perlite: vermiculite =5:3:2, and 5% bone meal is added as the base fertilizer. The 12cm pot is planted in a concentric circle layout, and the outer seed balls are spaced apart by a buffer space of 2 cm. Grape hyacinth growth cycle management During germination period, light regulation is maintained at 2000-3000Lux scattered light during germination stage, and gradually increases to 10000Lux direct light after the leaves are unfolded. Adopt the "progressive supplementary light method" to add 1 hour of sunshine every day until full sunshine conditions are reached, effectively preventing excessive internode growth. The collaborative management plan of water and fertilizer adopts the "weighing and watering method", and the water is poured thoroughly when the weight of the pot soil is reduced by 30%. Water-soluble fertilizer N-P-K=20-20-20 was applied during the vegetative growth period, and potassium dihydrogen phosphate (diluted concentration 0.2%) was used during the reproductive conversion period, combined with foliar spraying of boron fertilizer to improve the quality of inflorescences. Key techniques for post-flowering ball cultivation are pruned and 1cm of pedicels are retained, and calcium-magnesium compound fertilizers are replenished in time. When the natural yellowing degree of leaves reaches 60%, the "three-stage drying method" is used: drying in the shade for 3 days → drying in a ventilated place for 2 days → storing at a constant temperature of 15℃. It is recommended to use cedar wood chips to fill the ball and maintain 45% environmental humidity.
Through systematic cultivation and management, grape hyacinth can achieve continuous reflowering for 3-5 years. The key control points are nutrient accumulation during the bulb cultivation stage after anthesis and temperature and humidity control during storage over summer. It is recommended to establish a planting log to record the management parameters of each phenological period, and gradually optimize and form a personalized maintenance plan.
