How to spend the winter in the north
As a representative of tropical leaf-viewing plants, the winter conservation of rich bamboo in the north is facing severe challenges. This article will systematically analyze the key points of wintering from dimensions such as temperature, light, and moisture, and demonstrate the feasibility of outdoor wintering based on the unique climate of the north, so as to help you protect green plants for safe winter. 1. Precise control of the temperature of the core elements for winter maintenance of rich bamboo. In northern winter, the indoor and outdoor temperature difference can reach more than 30℃. Maintenance requires the establishment of a three-level temperature control system: the minimum living temperature is 10℃, the safe wintering temperature is 15℃, and the normal growth temperature is 20℃. The floor heating environment needs to be coordinated with a humidifier to keep the humidity>60%, so as to avoid high temperature drying causing leaf tips to become yellow. Special lighting strategy reduces the duration of direct sunlight in winter by 40% compared with summer. It is recommended that southbound window sills receive light for 6-8 hours a day. Using the "rotating maintenance method", rotate the flowerpot 180° every week to receive even light. Combined with leaf wiping, the photosynthetic efficiency can be increased by 30%. 2. Scientific water management in the northern special environmental response plan adopts the "three-degree control method": the temperature difference between water temperature and room temperature is ≤3℃, the soil humidity is maintained at 40%-50%, and the watering frequency is reduced to 15-20 days per time. It is recommended to use a water temperature meter for monitoring and cooperate with the bamboo stick insertion method to detect the humidity of the basin soil. The "hibernating fertilization method" is implemented in the adjustment of nutrient supply: phosphorus and potassium fertilizers are applied before the beginning of winter to enhance cold resistance (N:P:K=1:3:2), and fertilization is completely stopped in winter. Special reminder: If the temperature in the heating room continues to be greater than 18℃, 1/4 of the regular amount of nutrient solution can be added every month. 3. Experimental data on the feasibility demonstration of outdoor wintering show that in an environment of-5℃, frostbite occurs in unprotected rich bamboo within 4 hours. The winter night temperature in most areas in northern China is ≤-10℃. It is recommended to adopt the "triple protection method": winding insulation cotton on the main stem + covering the root with pine scales + building a temporary greenhouse to cope with the-5℃ environment in a short period of time (<72 hours). However, the long-term outdoor wintering success rate is less than 5%, so it is not recommended to try.
Through precise temperature control, light optimization and water and fertilizer management, northern flower friends can fully realize the safe winter of rich bamboo. Master the twelve-character secret of "giving priority to temperature, assisting in light, and focusing on dry care" to maintain greenery even in severe cold areas. It is recommended to regularly check the status of plants and adjust maintenance plans in a timely manner to rejuvenate tropical plants in the north.
