Soil should be disinfected before planting. If conditions permit, the soil can be screened, the larger soil blocks and stones can be cleaned, and then the soil can be reconfigured.
The potted soil planted shall be exposed to the sun, or sprayed with potassium permanganate, formalin, dixone, etc. in an appropriate proportion of water solution, and can be used after being dried.
Before planting, it is better to deal with the seeds first, which can improve the germination rate of the seeds. The simplest way is to soak in warm water for 6-8 hours, add some rooting powder, and then seed after germination.
After seed treatment, the seeds shall be evenly spread on the soil surface, not too dense, so as not to affect the germination rate of seeds.
Then cover the soil surface with a layer of 3 mm sandy soil, do not cover the soil block, too heavy. Water permeable, cover with plastic film to keep wet. Move to the sun, if you see that the plastic film is full of water vapor, you can open the ventilation, about 7-10 days can germinate.
The best germination temperature of fluke seedlings is 20 ~ 22 ℃, and the soil temperature has a great influence on the seeds, so the temperature should not be too low. After emergence, the temperature can be reduced to 15 ℃, a little lower temperature can form a good plant type and promote its growth.
After emergence, the seedlings should be carefully managed, and attention should be paid to water control and light replenishment to prevent the seedlings from growing in vain. When the seedlings grow to 6-7 cm, they can be transplanted. Note that fluke seedlings are not resistant to transplanting, do not repeatedly toss, and ensure that the roots are intact when transplanting.
