Knowledge of reusing seedling trays

2023-11-06 15:39:28

Caverns are generally reused. Caverns should be thoroughly cleaned and treated with special disinfectants such as quaternary ammonium salts before reuse to prevent the growth of root rot pathogens. For high-density polystyrene foam film discs that are not easily melted at high temperatures, steam disinfection can be considered, but they must be thoroughly dried before use. For thinner hole plates, the number of repetitions should not exceed 3 to prevent damage and leakage of water and matrix.


The seedlings in each hole of the seedling tray are relatively independent, and the root system can also be fully developed. Light substrate and light container make it easy to store and transport, reducing the spread of pests and diseases among each other and the competition for nutrition among young seedlings, achieving marketization of seedlings.


Increase seedling density, facilitate intensive management, improve greenhouse utilization efficiency, and reduce production costs. The hole tray seedling is easy to raise and transplant, without damaging the root system. After transplanting into the soil, the slow seedling period is short, and the survival rate of planting is high. Unified sowing and management can ensure consistent growth and development of seedlings, improve seedling quality, and facilitate large-scale production. The process of hole tray seedling cultivation, such as filling, sowing, and germination, can be completed using machinery, and the operation is simple and fast, making it suitable for large-scale production. The seeds are evenly distributed, with high germination rate, high seedling rate, and strong seedling vitality, which can save seeds.
