1. Selection and treatment of seeds: select seeds that are fully saturated and have high growth rates. The steps for seed treatment include seed selection, 55°c warm-water immersion, cold-water immersion. In the summer autumn festival, five minutes of bathing with warm water not exceeding 55°c and then with cold water; in the spring freezing season, 30 minutes of immersion with warm water at 55°c and then with cold water, 8-12h, adjusted to the size of the varieties and seed particles。
2. Treatment of seedlings: the seedlings must be prepared well in advance of seeding, the seedling basins cleaned, then fully disinfected, so that they can be immersed in raw lime water for a period of time, and then recovered after five or six minutes。
3. Scientific seeding: when seeding, care is taken to maintain homogeneity and homogeneity. After planting, no collisions should occur, so that the seeds do not shake and lead to uneven planting. After the foundation has been laid, the seedlings are to be poured into a suitable quantity of nutrients, immersed in them and then distributed evenly to the seedlings. It is also important to maintain ventilation after planting and to place it where the sun can be tilted。
4. Discretion management: with the growth of sprouts, there is a growing demand for light intensity, and when sprouts are harvested, they need to be transplanted into the sun to promote growth. The sprouts grow more vigorously and are usually harvested in about a week, and the sprouts feel good during this period。
5. Temperature and humidity management: the temperature required for the growth of budding vegetables should be kept at 16-25°c, too low to extend the growth cycle, and overfibrosis; overbreeding seedlings should be long, decorated, of lower quality and prone to impurity. Sprouts grow at a maximum humidity of about 80 per cent, are too low to cause death and are too high to lead to acclimatization. If wet overlay is low, water can be sprayed to increase moisture, and if wet overlay is high, the ventilation will be enhanced and the humidity reduced in a timely manner。
6. Light management: lighting according to different seedling growth needs. There is a need to see the light green, and there is a need to hide completely. Adjustment to actual situation。
Harvest: the seedling harvest is 10-15 cm high and is collected according to the characteristics of the species。
