When can the seeds of Clivia Miniata be planted after harvesting
As a widely loved ornamental plant, the seed propagation of Clivia Miniata is an important way to continue the plant's life. Many horticulture enthusiasts are often confused about the best sowing time and cultivation methods after harvesting fresh seeds. This article will systematically comb the key points of the whole sowing process from seed viability maintenance to practical steps.
Golden period for seed sowing
Advantages of immediate sowing after harvest
The newly harvested Clivia Miniata seeds contain about 40% water, and the germ is in an active state. Experimental data shows that the germination rate can reach 85% when sown within 7 days after harvest, while it drops sharply to 35% after storing at room temperature for 30 days. It is recommended to hang the spike with fruits in a well-ventilated place to dry for 2-3 days, and then collect the seeds after the seed pods naturally crack open.
Key points of special preservation techniques
If delayed sowing is needed, wrap the seeds with double-layer medical gauze and place them in a constant temperature environment of 12-15°C. Regularly check to prevent mildew, and spray with carbendazim solution once a month. This method can extend the viability of the seeds to 45 days.
Standard operation procedure for sowing
Seed pretreatment technique
Use a stepped soaking method: first activate with warm water at 30°C for 30 minutes, then disinfect with a 0.1% sodium dihydrogen phosphate solution for 25 minutes, and finally soak in pure water for 12-15 hours. After treatment, spread them on a bamboo sieve and dry in scattered light until the epidermis is slightly wrinkled.
Substrate proportion and disinfection
The ideal substrate golden ratio is leaf mold soil: red jade soil: perlite = 5:3:2. It needs to be sterilized with high-temperature steam or sprayed with 50% carbendazim 800x solution before use, ensuring the pH value is maintained between 5.8-6.5.
Precise sowing operation
Use the dot sowing method, maintaining a plant spacing of 2cm×3cm. Embed the seeds with the hilum facing down into the substrate, with a covering thickness of 1.5 times the diameter of the seed. Use the immersion pot method to water, maintaining an air humidity of 90%±5%, and it is recommended to use a transparent humidity cover to create a microenvironment.
Core elements of seedling care period
Control the temperature within the range of 20-25°C, with a day and night temperature difference of no more than 5°C. Maintain a light intensity of 3000-5000Lux, and supplement light for 4-6 hours daily. Regularly loosen the surface soil with a bamboo skewer to promote root respiration. After about 10-15 days, you can see light green seedlings breaking through the soil.
Mastering the critical period for sowing Clivia Miniata seeds, combined with scientific treatment methods, can increase the germination success rate by more than 60%. It is recommended to establish a sowing log to record the changes in temperature and humidity and the progress of seedlings, accumulating valuable data for subsequent transplantation.
