Introduction to seedling tray technology

Seedling plug technology is a modern seedling technology that uses peat, vermiculite and other light matrix soilless materials as the seedling substrate, mechanized precision sowing, one seed per hole, and one-time seedling growth.

Whether it is flowers or vegetables, seedling raising is a fundamental change in modern gardens, providing a guarantee for accelerated and mass production. Trays have become factory seedling trays, and seedlings are important equipment in the seedling production process. The materials for preparing plug plates are polystyrene foam, polystyrene, polyvinyl chloride and polypropylene. Manufacturing methods include blow molding and injection molding. Common vegetables and ornamental plants are made of polystyrene.

The standard plug size is 540mm*280mm. Because the hole diameters are different, the number of holes is between 18-800. 72 and 288-well plates are suitable for small and medium-sized seedlings. The hole shapes of the seedlings are square and round. The hole matrix is round and square holes account for more than 30%. The water is evenly distributed and the root system of the seedlings grows fully. The color of the seedling plug affects the temperature of the plant's root system. White polystyrene foam discs have good reflectivity and are used for early growing in summer and autumn to reflect light and reduce heat accumulation in the seedling roots. In winter and spring, black seedling plugs are good for seedlings to take root because of their good absorbency.

1. The filling, sowing, germination and other processes of plug seedling cultivation can be completed by machinery. The operation is simple and fast, and is suitable for large-scale production.

2. The seeds are sown evenly, the seedling rate is high, and the seed cost is reduced.

3. The seedlings in each hole in the plug tray are relatively independent, which not only reduces the spread of diseases and insect pests to each other, but also reduces the competition for nutrients among the seedlings, and the root system can be fully developed.

4. Increase the density of seedlings to facilitate intensive management, improve greenhouse utilization and reduce production costs.

5. Due to the unified sowing and management, the growth and development of seedlings can be consistent, the quality of seedlings can be improved, and it is more conducive to large-scale production.

6. Seedling transplantation is simple and convenient without damaging the root system. The survival rate of transplantation is high and the seedling slowing period is short.
