Do green radish need fertilizer in winter
As a common indoor leaf-viewing plant, the winter maintenance of green radish has attracted much attention. Many plant friends wonder: Do green radish need fertilization in winter? How to scientifically maintain green radish to survive the winter safely? This paper will comprehensively analyze the key points of winter conservation of green radish based on plant growth laws, from fertilization strategies to environmental control. Nutritional requirements characteristics of green radish during the dormant period when the temperature is below 15℃, green radish enters a semi-dormant state, at which time the metabolism slows down, and the root absorption capacity drops to 30%-40% of the peak growth season. However, completely stopping fertilization may lead to malnutrition in the plants, so it is recommended to adopt the principle of "eating light and eating multiple meals". The optimal fertilization window period for scientific fertilization time nodes is early winter (temperature 15-18℃) and early spring when it warms up. It can be judged by observing the growth rate of new leaves. If one new leaf grows every two weeks, liquid fertilizer supplementation can be maintained once a month. Practical Operation Skills for Overwintering Fertilization of Green Rose Special fertilizer selection standards recommend using a balanced foliar fertilizer with an NPK ratio of 1:1:1, and the concentration needs to be diluted to 1/3 of the regular amount. Pay special attention to the selection of fertilizers containing magnesium to prevent yellow leaves in winter. Precise fertilization steps 1. Fertilization at noon (10:00-14:00) 2. When spraying, evenly atomize 20cm away from the leaves 3. Keep the environment ventilated for 2 hours after fertilization 4. In conjunction with wiping leaves to improve stomatal absorption rate, the greenhouse environment is regulated. In a greenhouse with a constant temperature of 18-25 ° C, the fertilization frequency of 15 days per time can be maintained. It is recommended to cooperate with the carbon dioxide replenishment system to increase the fertilizer utilization rate by 40%. Low-temperature coping strategies When the room temperature continues to be lower than 10℃, fertilization should be stopped immediately and the following measures should be taken: -Use a transparent insulation cover to maintain local temperature-lay a pine scale insulation layer on the surface of the pot soil-Use LED plant fill light to maintain photosynthesis Through scientific fertilization and environmental control, the survival rate of green radish over winter can reach more than 95%. It is recommended to regularly observe the condition of the leaves and adjust the maintenance plan in time when the blade tips are scorched or growth stagnated. Remember that the core of winter maintenance is to balance the dynamic relationship between plant fertilizer requirements and metabolic ability.
