Whether it is flowers or vegetables, plug seedling is a fundamental change in modern horticulture, which provides a guarantee for fast and mass production. Plug tray has become factory

An important tool in the seedling production process.

The materials for making plug trays generally include polystyrene foam, polystyrene, polyvinyl chloride and polypropylene. There are blow molding and injection molding methods. Common vegetable and ornamental plant seedling trays are made of polystyrene material.

The size of the standard plug tray is 540mm×280mm, and the number of holes is between 18-800 due to different hole diameters. For the cultivation of medium and small seedlings, 72-288 hole plugs are suitable.

The hole shapes of the seedling trays are mainly square and round. The square hole contains about 30 more substrates than the round hole. The water distribution is also more uniform, and the seedling root system is more fully developed.

The color of the seedling tray will affect the temperature of the plant roots. The white polystyrene foam plate has better light reflectivity and is mostly used for early seedling cultivation in summer and autumn to reflect light and reduce heat accumulation at the roots of the seedlings. In winter and spring, choose black seedling trays because of its good light absorption, which is beneficial to the greening of seedling roots.
