Cherry trees are often sown in autumn in late September.
1. Matrix disinfection to prevent bacterial infection. The commonly used disinfection methods are insolation, which can directly expose the soil in the sun, or stir fry the soil in a pot to directly kill pests.
2. Germination: soak the seeds in warm water for three to ten hours, until the seeds absorb water and expand.
The Nanking cherry trees were evenly seeded in the nursery tray, covering about 1 centimeters. After sowing, the seeds were drenched with sprayers. When the soil was slightly dry, attention should be paid to the continuous watering. The intensity of watering should not be too large, so as not to rush the seeds.
After sowing in autumn, in case of cold wave and low temperature, the flowerpot can be wrapped with plastic film to facilitate heat preservation and moisture preservation; after the seedlings are unearthed, the film should be uncovered in time and the seedlings should be exposed to the sun before 9:30 a.m. or 3:30 p.m. every day, otherwise the seedlings will grow very weak; after most of the seeds are out, the seedlings need to be properly intercropped. The diseased and unhealthy seedlings are pulled out, so that there is a certain space between the left seedlings; when most of the seedlings grow three or more leaves, they can be transplanted into the basin.
