What are the advantages of plug seedling cultivation?

We all know that plug seedling cultivation is a seedling cultivation technology that uses containers for once-grown seedlings and soilless cultivation. Its appearance has been recognized by most people, so do you know what advantages it has? Let's take a look together.

1. The substrate used for plug seedling cultivation is mainly peat soil, vermiculite, perlite and other light substrates. These substrates have light specific gravity, good air permeability and water retention, moderate pH, and less virus contamination. The substrate used for plug seedling cultivation does not adhere to the surface of the plug tray and is easy to come out of the tray. It does not stick to the surface of mechanical parts, making it easy for mechanical operation.

2. The germination rate of plug seedlings is high, and the seedlings have strong vitality, which greatly saves seeds, so that seedling companies can safely use high-quality seeds with high value.

3. The density of plug seedlings is several times higher than that of traditional seedlings. Therefore, the greenhouse fixed investment cost and greenhouse operating cost amortized per seedling are greatly reduced.

4. The root mass formed by the network of the root system and the matrix of the plug seedlings is quite strong. Regardless of manual or mechanized transplantation, the root mass is not easy to spread out and be injured. After transplanting, the plug seedlings can grow rapidly without the slowness of traditional seedling raising. Seedling stage.

5. Mechanized sowing can be used for seedling cultivation in plug trays. The use of a seeder assembly line can make the substrate filling amount, seeding depth, compaction degree, and coverage depth of each hole in the plug tray basically consistent. The emergence date and seedling size are uniform, which is conducive to the commercialization of seedlings. .

6. The entire plug seedling production line is easy to disinfect.

7. It is easy to carry out centralized transportation, and commercial seedlings can be transported over long distances to expand the scope of supply.
