Babyster seeds germinate in a few days
As a beautiful ornamental plant like a starry sky, Gypsophila is favored by gardening enthusiasts for its slender branches and dense small flowers. Mastering sowing techniques and seedling maintenance points is the key to successfully cultivating such exquisite flowers. This article will systematically analyze the technical points of the entire process from sowing to seedling management. The optimal germination temperature range for controlling the germination cycle of Gypsophila japonica seeds is 15-20℃ and a constant temperature environment can significantly shorten the germination cycle. It is recommended to choose from late March to early April for spring sowing, and September is better for autumn sowing. Low-temperature environments require greenhouse or film insulation measures to avoid the temperature difference between day and night exceeding 8℃. The sowing operation specifications use a 3:1 mixed substrate of peat soil and perlite, and the sowing depth is controlled at 2-3 mm. Keep the substrate humidity at 60%-70%, and a stable humidity environment can be maintained through a spray humidifier. Under normal management, soil can be broken in 3-4 days, and in extreme cases, observation needs to be extended to 7 days. Scientific maintenance system for gypsophila seedlings Progressive light management Implement stepped light adaptation after sprouting: receive weak light (<5000lux) in the morning/dusk for the first 3 days, and increase it to half-day scattered light (10,000 - 15,000 lux) on the 4-7 days to avoid direct strong light at noon. When using a sunshade net for adjustment, it is recommended to choose a black sunshade net with 50% light transmittance. Intelligent moisture control adopts the principle of "seeing dry, seeing wet", and water is replenished immediately when the substrate surface is dried 1 cm. It is recommended to use an atomizing nozzle with a hole diameter of 0.3mm, or use the immersion basin method to make the water level reach 1/3 of the height of the basin, and each time water replenishment should not exceed 15 minutes. The air humidity should be maintained between 55% and 65%. Scientific thinning operation carries out thinning 2-3 times when the main leaves are unfolded, and the plant spacing is kept at 4-5cm. Priority should be given to removing weak seedlings with yellow leaves and too dense internodes, and retaining strong plants with thick leaves and upright stems. Immediately after thinning, root water was poured and brassinolide diluted by 2000 times was added to promote root development.
It takes about 20-25 days from the breaking of seeds to the formation of strong seedlings, and it is crucial to maintain environmental stability at this stage. By accurately controlling the three major factors of light, moisture and density, the survival rate of seedlings can be significantly improved. After mastering these core skills, growers can smoothly transition to the subsequent fertilization and styling management stages, and finally harvest star-like flowers.
