1.Features: wide adaptability, can sown a variety of crops; the root system is tightly entangled with the substrate, and there is no slow seedling period after planting
2. Advantages compared with traditional seedling cultivation:
(1) Energy saving. Traditional seedling raising 100 plants/M2, plug seedling raising 700-1000 plants/M2, energy saving 2/3
(2) Save labor and effort, and have high efficiency. The traditional nursery soil tuft weighs 500-700g, and the plug substrate is less than 50g
(3) The quality of seedlings is high.
(4) Suitable for long-distance transportation.
