The seeds and culture medium of goldfish grass need to be disinfected before sowing. The seeds of goldfish grass were immersed in potassium permanganate solution with a concentration of about 0.5% for 1-2 hours. You can add a proper amount of methyltobuzin powder into the medium, and stir it for 2 or 3 times to make it fully mixed with the medium, and then mix it while spraying water. It is better to hold the medium into a group with hands, and loosen it without scattering it. Finally, cover it with a film, place it for about 8-10 hours, and then install it in the hole plate..
The seed of goldfish grass is relatively small. Before sowing, apply base fertilizer in the basin, and then sprinkle the seed. Generally, 200 seeds can be sown in each hole plate, and one seed can be placed in each hole. After sowing, press it gently by hand to make the seed adhere to the medium, spray it through water, and finally cover it with newspaper or plastic film. It is unnecessary to cover the soil for sowing. Then wait about 7-10 days to be unearthed.
Goldfish grass is a kind of light loving plant for germination. The suitable germination temperature is between 20-22 ℃. It needs to be given a proper amount of light, but attention should be paid to avoid direct sunlight, keep the medium moist at the same time, and keep the newspaper moist for a long time until the seeds are germinated before turning the newspaper over. It usually sprouts in 7-15 days. After germination, seedlings need to be moved to a temperature of 16 - 18 ℃.
After 5-7 weeks of growth, goldfish grass can be directly put into a 7-8 cm basin. Goldfish grass likes light. It's a long sunshine plant. The sunshine time is more than 12 hours, which is more conducive to flower bud differentiation. According to this feature, it can supplement light properly to promote its early flowering, but at the same time, it should pay attention to prevent the harm caused by too high temperature.
