Can Narcissus Be Cultivated in Soil
As a representative of winter ornamental flowers, narcissus is often decorated in homes through hydroponics. But did you know? This elegant and fragrant plant can achieve even more vigorous growth through soil cultivation! This article will delve into the unique advantages of narcissus soil cultivation and provide professional-level operation guidelines.
Core Advantages of Soil Cultivation for Narcissus
More Abundant Nutrient Supply
Compared to hydroponics, soil rich in humus can continuously release nitrogen, phosphorus, and potassium elements, and regular top dressing can increase the bulb expansion rate by 30%.
Healthier Root Development
The combination of a breathable matrix and a dry-wet cycle mechanism can effectively prevent the common root rot problem in hydroponics, increasing root density by 2-3 times.
Four-Step Rule for Soil Cultivation of Narcissus
Golden Soil Formula
Use a mixed matrix of peat soil: perlite: decomposed leaf soil = 5:3:2, and add 10g bone meal per liter to increase phosphorus content. The pH value should be controlled between 6.0-6.5.
Pre-treatment Technique for Bulbs
After peeling off the outer brown scales, soak in a 50% carbendazim solution (800 times) for 20 minutes, and dry until the incision contracts (about 48 hours).
Scientific Planting Standards
Plant using the shallow burial method, keeping 1/3 of the bulb exposed above the soil surface. The recommended pot diameter should be twice the circumference of the bulb to ensure space for lateral bud growth.
Temperature, Light, and Water Management
Maintain a scattered light environment of 15-18°C during the rooting stage, and gradually increase to 6 hours of direct light after new roots emerge. Use the immersion pot method for watering, maintaining a matrix moisture level of 40%-60%.
Advanced Care Tips
Techniques for Flowering Control
During the bud formation stage, spray a 0.1% phosphorus acid potassium solution, combined with low nighttime temperatures (10-12°C) treatment, to extend the flowering period by 5-7 days.
Regeneration Cultivation Plan
After flowering, retain 3 functional leaves, and apply a special slow-release fertilizer for flowers monthly, which can achieve a regeneration rate of over 85% for the bulbs.
Through scientific soil cultivation management, narcissus can not only display a plumper flower shape but also achieve multi-year cyclic cultivation. Mastering these key techniques will allow your narcissus to bloom with lasting fragrance in the soil!
