105 Holes Plastic Seedling Tray Nursery Tray

Hole tray, also known as seedling tray, has become an important instrument in the factory seedling production process. Whether it is flowers or vegetables, hole plate cultivation is the most fundamental change of modern horticulture, which provides a guarantee for fast and mass production. The materials for making cavitation disks are generally polystyrene foam, polystyrene, polyvinyl chloride and polypropylene. The manufacturing methods are blow molding and injection molding. The common vegetable and ornamental plant seedling hole plate is made of polystyrene material.

The hole shape of seedling hole disk is mainly square and round. The matrix contained in the square hole hole is about 30% more than that in the round hole, the water distribution is more uniform, and the root system of the seedling is more fully developed. The size of the standard hole plate is 540mm×280mm, and the number of holes ranges from 18-800 due to the different hole diameters. For medium and small seedling cultivation, 72--288 hole plates are suitable.

The color of the seedling tray affects the root temperature of the plant. White polystyrene foam disk reflective better, more used in summer and autumn early seedling, to reflect light, reduce the root heat accumulation. The choice of black seedling tray in winter and spring, because of its good light absorption, is conducive to green seedling roots. After the seedlings grow up, they should start to use the root control rapid seedling technology, move into the root control rapid seedling container, and continue to grow.
