What should I do if the narcissus grow crazily?
It is an elegant thing to bloom during the New Year, but the leaves grow and fall crazily and the flower stems are thin and weak, which give many flower friends headaches. The excessive growth of narcissus not only affects the ornamental quality, but also consumes the nutrients of the bulbs and shortens the flowering period. This paper analyzes the causes from the perspective of plant physiology, and systematically combs the four major control techniques and three maintenance points. Analysis of the causes of daffodils 'wild growth caused by imbalance of light. Daffodils are typical photoperiodic plants that require more than 6 hours of direct light during the day. Experimental data show that when the light intensity is below 3000 lux, the plant will produce excessive gibberellin, causing the internode spacing to lengthen by 40%-60%. Temperature fluctuations accelerate growth. When the temperature difference between day and night is less than 8℃, the metabolic rate of narcissus accelerates. Especially in environments where the night temperature exceeds 15℃, the respiration of plants is enhanced, and the phenomenon of "growing 3 centimeters overnight" is prone to crazy growth. Four methods to control the wild growth of narcissus at night water control method Pour away the accumulated water in the basin at 17:00 every day. By limiting the absorption of water at night, it can effectively inhibit cell elongation. Experimental results show that this method can reduce plant height by 30%, and maintain root vitality with morning water replenishment. The temperature difference control method maintains the golden temperature difference of 18℃ during the day/10℃ at night, and uses intelligent temperature control equipment to adjust it. For every 1℃ increase in the temperature difference, the plant growth rate slows down by 12%-15%. Tips for using chlormequat Select a special preparation containing CCC (chlormequat) and dilute it at a ratio of 1:1500. Spraying on the leaves every week during the budding period can increase the thickness of the flower stem by 0.5mm and extend the flowering period by 5-7 days. Light management points for daily maintenance of narcissus adopt the combination of "east-facing balcony + fill light" to ensure 9 hours of daily light. Turn on the LED plant lights for 2-3 hours in rainy days to maintain photosynthesis efficiency. Nutrient ratio When hydroponic cultivation, add hydroponic nutrient solution containing phosphorus and potassium, and control the ratio of nitrogen, phosphorus and potassium at 1:3:2, which can not only promote flowers but also prevent excessive leaf growth.
Through a three-pronged approach of light control, temperature difference management, and scientific medication, and daily refined maintenance, the daffodils can maintain a beautiful plant type. It is recommended to measure the change in plant height every week and take timely control measures when the growth rate exceeds 0.8 cm/day to allow Lingbo Fairy to bloom gracefully.
