How to raise daffodils on the balcony
As a representative of flowering plants in winter, daffodils can not only purify the air but also add vitality to maintenance on the balcony. Mastering scientific maintenance methods can effectively prolong the flowering period. This article will systematically explain the practical skills of cultivating family narcissus from environmental control to maintenance details. Light environment control average daily light duration Narcissus is a highly positive plant. It is recommended to ensure 4-6 hours of direct light every day. South-facing balconies are the most suitable. They can be maintained under full sunshine in spring and autumn, and gauze curtains are needed to filter strong light at 10-15 o'clock in summer. In winter, you can receive sunshine all day long, which naturally increases the temperature of the basin soil through light. The seasonal adjustment plan implements full sunshine management from November to March of the following year, maintains half sunshine from April to June and September to October, and only 3 hours of morning light per day during the high temperature period from July to August. By rotating the flowerpot to achieve uniform light reception, preventing the plant from growing off the crown. Cultivation substrate management Soil culture moisture control uses a 3:1 mixed substrate of peat soil and perlite, which has good water retention and air permeability. Watering follows the principle of "seeing dry, seeing wet", and inserting bamboo sticks to test soil moisture. The micro-tide state is maintained in winter, and the water content is increased to 60% during the spring germination period. In the early stage of hydroponic system maintenance, water was changed daily to stimulate root development, and was replaced on three days after 2 weeks. Use tap water that is dried for 24 hours, and the temperature difference between the water temperature and the room is controlled within ±2℃. It is best to submerge 1/3 of the bulb at the water level, and clean the algae on the inner wall of the container regularly. Nutrient supply strategy Soil culture and fertilization cycle Pre-buried bone meal as base fertilizer during planting, and phosphorus and potassium liquid fertilizer (diluted 1500 times) is applied every half month during the growth period. Apply potassium dihydrogen phosphate foliar fertilizer during the bud appearing period, and supplement compound fertilizer after flowering to restore corm nutrients. Hydroponics nutrient supplement When changing water, add special nutrient solution for hydroponics, and the concentration is controlled at 0.8-1.2‰. Adding boron-containing nutrients every week during the flowering period can extend the flowering period of a single flower by 3-5 days. Regularly prune aging roots to improve nutrient absorption efficiency.
By accurately controlling the duration of light and scientifically managing the water and fertilizer system, balcony narcissus can achieve continuous flowering year after year. Pay attention to maintaining a low temperature of 8-15 ° C in winter and cutting off residual flowers in time after flowering to retain nutrients, so that the bulbs can accumulate energy and wait for the next flowering cycle.
