What should I do if there is no heating in winter
As a popular indoor leaf-viewing plant, green radish's weak cold resistance has become a difficulty in winter maintenance. When the environmental temperature is lower than 10℃, the leaves are prone to freezing spots, wilting and even entire plant death. This paper systematically analyzes the wintering plan of green radish in an unheated environment, and provides emergency response guidelines at the extreme temperature of 0℃. 1. Green radish triple protection method in unheated environment 1.1 Space transfer strategy Closed balcony in the north and open window sill in the south need to be treated differently: the indoor temperature gradient shows the characteristics of the higher the ground, the lower the temperature. It is recommended to place the plant 50cm away from the ground. Solid countertops, away from cold air inlets such as gaps in doors and windows. Special reminder: Do not place it on the floor heating. High temperature baking will accelerate the drying of the basin soil. 1.2 Physical insulation plan Bagging operation requires selecting PE material with good light transmission, and opening it for ventilation from 10:00 to 15:00 every day. Advanced skills: Hang a small cloth bag filled with activated carbon inside the bag to effectively regulate humidity and prevent mildew. It is recommended to adopt a three-layer structure for flowerpot packaging: inner bubble film → middle nonwoven fabric → outer aluminum foil insulation cotton to form a gradient insulation system. 1.3 Collaborative management of light and temperature In winter, lighting must follow the principle of "chasing light but not chasing temperature": the daily light received by south-facing bay windows should be controlled within 4 hours to avoid concentrated burns on glass windows. Turning on the humidifier synchronously during the light period and maintaining 40%-50% air humidity can improve the cold resistance of leaves by 2-3℃. 2. Guidelines for Rescue of Zero Extreme Environments When a cold current attack causes the ambient temperature to plummet to 0 ° C, a three-level Incident Response Service should be activated: ① Immediately cut off frostbitten leaves and block low-temperature conduction ② Soak the basin with 35 ° C warm water for 20 minutes and slowly warm it up ③ Build a temporary insulation shed with built-in LED plant fill light to continue to provide a basic heat source of 5 ° C. Data shows that this plan can increase the survival rate of green radish to 78%.
Through scientific space management, physical insulation and light and temperature control, green radish can be ensured safely through the winter even without central heating. It is recommended to use an infrared thermometer to monitor the leaf surface temperature every month, and immediately activate an emergency plan when it continues to fall below 8 ° C, so that green radish remains full of vitality in the cold winter.
