The seedling tray, that is, the hole tray, the specific operation method:

The plug tray, also known as the seedling tray, has become an important tool in the factory seedling production process. Whether it is flowers or vegetables, plug seedling cultivation is the most fundamental change in modern gardening, which provides a guarantee for fast and mass production. The materials used to make trays generally include polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene. Manufacturing methods include blow molding and injection molding. General vegetable and ornamental plant seedling trays are made of polystyrene materials

1. Selection and disinfection of plug trays: The external dimensions of the plug trays are mostly 54.9×27.8cm, and the specifications of the plug trays are 72 holes and 108 holes respectively. 99 kg of water), soak for 8-10 hours, take it out and dry it for later use.
2. Matrix preparation: At present, the commonly used matrix materials for seedling cultivation in plug trays are peat, vermiculite, perlite, etc. Most of them use peat: vermiculite: perlite = 2:1:1, and an appropriate amount of inorganic fertilizer should also be added to the matrix And organic fertilizer, generally add 2.6-3.1 kg of nitrogen, phosphorus and potassium compound fertilizer 15:15:15 and 10-15 kg of deodorized chicken manure and other organic fertilizers per cubic meter of substrate. The pH value of the substrate is 5.8-7.0. Peat is composed of semi-decomposed marsh vegetation, with a pH of 3.8 to 4.5, fine texture and poor air permeability. It is often mixed with vermiculite or perlite. Substrate disinfection.

3. Packing: First of all, the matrix should be prepared, and the prepared matrix should be placed on the plate. When loading the plate, be careful not to press it hard, because after pressing, the physical properties of the matrix will be damaged, and the air content in the matrix will be damaged. And the content of absorbable water is reduced. The correct way is to use a scraper to scrape from one side of the tray to the other, so that each tray is filled with matrix, especially the holes at the four corners and the sides of the tray must be the same as the holes in the middle. , the matrix should not be overfilled, and each cell should be clearly visible after filling.

4. Cavity pressing: The installed trays should be pressed to facilitate the insertion of seeds. You can press the holes with a special presser, or you can stack the trays with the matrix vertically together, and place 4 to 5 trays at a time. , put an empty plate on it, put both hands flat on the plate and press down evenly to the required depth.

5. Sowing: Put the seeds on the tray with well-pressed holes, one seed per hole, to avoid missed sowing, and sow 2 seeds per hole for seeds with low germination rate.

6. Covering the substrate: After sowing, cover the plug with vermiculite. The method is to pour the vermiculite on the plug, and use a scraper to scrape from one side of the plug to the other to remove the excess vermiculite. The vermiculite should not be too thick , It is advisable to be on the same level as the cell.

7. Put the seedling tray into the bed: place the seedling tray that has been sown in the seedbed, and pour the seedling tray thoroughly with clean water in time. When watering, spray lightly and evenly to prevent the substrate and seeds in the hole from being washed out. The seedbed is covered with a layer of plastic film to prevent water loss in the seedling tray. When covering the plastic film, it is necessary to place some small bamboo strips on the seedling tray so that there is a gap between the film and the seedling tray without bonding. It is also possible to dip the tray into the water tank before sowing after the substrate is loaded into the tray. The water will slowly seep upward from the bottom of the tray to absorb water more evenly, and then put it into the seedbed.

8. Seedling management. Transplanting seedlings to fill the gap: after emergence, the plastic film covering the seedbed should be removed in time to prevent the formation of "high-legged seedlings" due to the delay in removing the film. Thinning and transplanting seedlings should be carried out immediately after the cotyledons are unfolded, and the redundant seedlings in the single hole should be pulled up and moved into the holes lacking seedlings, and the redundant seedlings in the holes should be deleted at the same time. Water management: The medium capacity of the seedlings in the plug tray is small, the porosity is large, and the water can be absorbed less. The seedbed has a small buffer for the water supply of the seedlings. Spray water in time when the weather is cool in the evening.

Plug seedlings

Common types of crops suitable for seedling cultivation in plug trays

vegetable

Solanaceous fruits: tomato, eggplant, pepper.

Melons: cucumber, pumpkin, watermelon, melon, bitter gourd, loofah, etc.

Cabbage: cabbage, broccoli, kohlrabi, kale, etc.

Others: okra, etc.

flowers

Cut flowers daisy, gerbera, tulip, sage, violet and more.

Suitable seedling time

The seedling raising time is determined according to the type of vegetables to be planted, the seedling raising environment, and the selected planting method. Solanaceous vegetables are generally seeded 60-70 days before planting; melon crops (such as watermelon, melon, cucumber, etc.) are seeded about 25-30 days before planting.

Trays of different sizes

The plug tray is an important carrier for plug seedling cultivation, and there are plug trays with different numbers of seedling holes such as 20, 50, 72, 128, 200, 288, and 512. Among them, the 50-hole tray is suitable for eggplant, melon and other vegetable seedlings, the 72-hole tray is suitable for solanaceous fruits, melons, beans, etc., and the 128-hole tray is suitable for leafy vegetables, cabbage, short seedling tomatoes, peppers, etc. . The selection of the number of holes in the plug plate is related to the type of vegetable, the age of seedlings and the season.
