planting methods and key points of lettuce with balls
1. Selecting varieties
Choosing varieties of lettuce with balls should be combined with the environment of the breeding place, so that the survival rate can be high and the yield can be high. This variety with balls is not easy to ball when the temperature is high in summer, so protective measures should be taken to prevent heatstroke and cool down.
2. Seeding and seedling raising
In general, the seeds of lettuce should be treated first. The seeds should be soaked in water at room temperature for about 12 hours, then taken out, washed with clear water, wrapped in a wet gauze, and placed in a low temperature environment for two days. When about 8% of the seeds begin to show white, they should be taken out for sowing. After sowing, the soil cover is generally about 1 cm.
Points for attention in daily management of lettuce
In daily management of lettuce, pests and diseases should be mainly prevented, such as Sclerotinia sclerotiorum and soft rot, which are more harmful and easy to be infected under warm and humid conditions. Therefore, the planting density can be appropriately reduced, the watering times should not be too much, and the soil surface can be kept dry and cleaned frequently, which can be effectively prevented.
