Breeding method of green radish in winter
Winter is a critical period for the maintenance of indoor green plants. As a popular leaf-viewing plant, large-green radish often suffers from problems such as yellow leaves and wilting due to low temperature drying. Mastering scientific maintenance methods can not only help plants survive through the winter safely, but also maintain their year-round green beauty. This paper explains in detail the key points of maintaining green radish in winter from the three core dimensions of light management, humidity control, and temperature control. Winter light management skills Although the green radish is resistant to shade, it still needs to scatter light for 4-6 hours a day in winter. It is recommended to place the plant within 1.5 meters of the southbound window sill, or use a double gauze curtain to filter direct light. In the northern region, full-spectrum plant fill light can be used to fill light for 2 hours in the morning and evening every day. Pay attention to rotating the flowerpot regularly to avoid the plant type being skewed due to phototaxis of the leaves. To handle floor heating in special scenarios, the flowerpot needs to be raised 3-5cm high and heat insulation boards are used to block the heat radiation. In haze weather, you can wipe the leaves with a soft cloth dipped in beer water (1:50), which can not only clean dust but also replenish nutrients. Precise humidity control plan It is recommended to maintain 60-70% ambient humidity in winter, which can be achieved in three ways: ① The ultrasonic humidifier is operated for 4 hours a day;② The pebble water tray is placed under the plant;③ The morning and evening leaf spray (with 3 drops of Melia oil) Insect insects). Watering follows the "three-look principle": look at the soil surface to dry completely, see if the leaves are slightly wilted, and see if the temperature is>15℃ before watering thoroughly. Watering taboos Avoid watering cold water at noon causing root stress. The water temperature should be consistent with room temperature. Use tap water that is dried for 24 hours, or collect rainwater/snow water, preferably. The layered temperature control strategy maintains the ideal temperature difference between day and night at 5-8℃: 18-22℃ during the day and 13-15℃ at night. Heating rooms in the north can be monitored in real time with a thermohygrometer. When the temperature is greater than 25℃, windows should be opened for ventilation. Plastic film can be used to build temporary greenhouses in wet and cold areas in the south, and built-in water cups can increase humidity at night. Emergency treatment for freezing damage found that leaf transparency should be immediately: ① cut off the frostbite parts;② move to an environment of 10℃ to slow down seedlings;③ spray alginin (1:1000) to repair cells. Do not bake at high temperatures immediately, as sudden changes in temperature difference will aggravate the damage.
Through the three-dimensional control of light, humidity, and temperature, and regular inspection of pests and diseases, green radish can not only safely survive the winter, but also achieve sustainable growth in winter. It is recommended to apply phosphorus and potassium fertilizers once a month to enhance cold resistance, and change pots and prune roots in time after spring to lay the foundation for a new growth cycle.
