The first stage is from the penetration of bacon through its seed coat to germination, from the penetration of young roots to the growth of cotyledons. The temperature shall be maintained at 18 ℃. Keep the cultivation medium moist and the seeds like sunshine and warmth, so it is not necessary to cover the soil, but to avoid direct sunlight, remember not to let the medium dry. In this stage, the pH value is kept between 5.5 and 6.2, and the relative humidity is 100%. After sowing in the lower basin, shade it properly.
From the cotyledons, the true leaves gradually grow and enter the second stage. Keep the room temperature at 18 ℃. The humidity of the medium should be kept between 70% and 80%, of course, it should not be too dry. The growth of cotyledons needs to be completed by the roots penetrating into the medium to absorb nutrients. The first two phases take a total of 2-3 weeks.
The third stage is from the true leaf to 80% of the seedlings. The room temperature can be reduced to about 15 ℃. When the temperature is lower, the humidity will also be lower. The interval between two watering can be longer, and then watering after drying, so as to form a dry and wet cycle, which is conducive to the growth and development of roots.
At this stage, the root system has been well formed, and the seedlings become cold resistant through seedling refining, lasting for about a week. Temperature, humidity and fertilization are basically the same as the previous stage. It needs to be transplanted and potted in time. The latter two stages need about 1-2 weeks to complete.
1. The cool potted environment can make the plant compact.
In winter, the high humidity of potted plants causes the leaves to become moist, which leads to grey mould. The humidity of potted plants should be kept suitable.
3. Daisies are clustered with base leaves, so it is necessary to keep ventilation to prevent the base from rotting.
