Corydalis seed is very small, generally choose 200 or 288 hole plate for sowing, sowing medium generally choose imported seedling peat or domestic seedling peat after disinfection, PH value is 5.5-6.2. After sowing, the seeds need to be covered with a thin layer of vermiculite to moisturize. If the substrate is too dry, it may lead to irregular germination and the germination temperature is maintained at about 20 ℃.

Stage 1: embryonic roots appear and begin to take root within 3 or 4 days.

When the temperature is controlled at 20 ℃-21 ℃, germination does not need light, but light of 50-200 lux can promote germination.

Stage 2: germination is completed, stems appear and cotyledons unfold.

The key point of this stage is to let the substrate dry slightly to help the roots insert the substrate, the temperature is controlled at about 20 ℃ during the day and 18 ℃ at night, and 4000 times nitrogen fertilizer or calcium fertilizer is applied. In addition, Corydalis does not need to replenish light at night, otherwise it will lead to early flowering.

Stage 3: the root is inserted into the hole of the acupoint plate

When the first true leaf appeared, the temperature control and fertilizer application remained the same as the second stage, and the light was controlled between 25000 and 30 000 lux.

Stage 4: the root system can easily fix the disk matrix and form a root mass.

When there are two or three pairs of true leaves, maintain proper humidity to avoid excessive growth of seedlings. In order to blossom early and reduce the night temperature to 15 ℃, the fertilizer use was the same as that of the third stage, and the light was controlled between 30, 000 and 35000 lux.
