Conservation of Clivia seedlings in winter
As the temperature gradually drops, many flower lovers begin to worry about the overwintering problem of Clivia seedlings. As a typical greenhouse plant, Clivia seedlings have special needs for temperature, light and nutrients. Especially in low temperature environments in winter, it is necessary to ensure normal growth of plants and avoid freezing damage, which puts forward higher requirements for maintenance technology. Today, we will discuss the core issues of winter maintenance. Temperature control points for the three key elements of winter seedling maintenance The suitable growth temperature of seedlings must be maintained within the range of 15-30℃, and the temperature at night in winter must not be lower than 12℃. It is recommended to move indoors to sunny places in the northern region, while temporary insulation sheds need to be built for dry farming in the southern region. When the thermometer shows 13 ° C, heating measures should be taken immediately. A special plant insulation film or a small heater can be used to assist in heating up. Light management skills The sun is soft in winter and full sunshine maintenance can be accepted. It is recommended to maintain light for 6-8 hours a day and rotate the flowerpot 180 degrees every 3 days to allow the leaves to receive light evenly. In case of continuous rainy days, you can use a plant fill light to fill light for 2-3 hours a day, and the lamp distance should be kept at 30-50 cm. The water control method adopts the principle of "see wet when it is dry", and the basin soil is completely dried and poured with water. It is recommended to use drying water close to room temperature, and the watering time is at noon on a sunny day. The humidity can be determined by the bamboo stick test method: insert the bamboo stick into 2/3 of the pot soil, leave it for 5 minutes, and then pull it out to observe humidity traces. Scientific use plan for potassium dihydrogen phosphate The correct proportion principle is to dilute potassium dihydrogen phosphate to a concentration of 0.1%-0.2%, that is, 1 gram of fertilizer mixed with 1-2 liters of water. A lower concentration (0.05%) is recommended during the seedling period and is applied once a month. The concentration can be increased to the standard concentration during the bud pregnancy period and sprayed on the leaves once every 10 days, paying attention to avoid the strong noon period. Dual application method root irrigation method: Slowly water 50ml of fertilizer solution along the edge of the pot and use it in conjunction with the watering cycle. Leaf spray method: Use an atomizing spray can to evenly spray the back of the leaves, focusing on taking care of the newborn leaves. The two methods need to be used alternately 10 days apart to avoid excess nutrients. Precautions indicate that fertilization should be stopped when the ambient temperature is lower than 15℃, and newly planted plants need to be delayed for one month before fertilization. If the leaf tips are found to be yellow, stop fertilizer immediately and wash the substrate with clean water. It is recommended to use pH test paper together to keep the soil pH between 6.0 and 6.5.
Through scientific and systematic maintenance and management, Clivia seedlings can not only survive the winter safely, but also accumulate energy for growth in the coming year. The key is to grasp the balanced relationship between the bottom line of temperature, light intensity and nutrient supply, especially the use of potassium dihydrogen phosphate to achieve "thin fertilizer and frequent application." It is recommended to regularly observe the status of the plants and adjust maintenance strategies in a timely manner so that the seedlings can grow healthily and healthily.
