Ground groove type strawberry safe seedling cultivation method capable of regulating water level

The invention discloses a ground type strawberry safe seedling cultivation method capable of regulating a water level. The water level can be regulated by a root limiting sheet; after the water is supplied, an organic substrate absorbs water between a hole tray and the root limiting sheet to allow the hole tray and water to be automatically separated, so that the water logging will not happen; the accumulated residual water is conducive to the cooling of the strawberry seedlings, the effect of the seedling cultivation at a low temperature can be achieved, and the flower bud differentiation of the strawberry seedlings is promoted. Compared with the conventional shelter seedling cultivation mode on ground, the mode brings remarkable early maturing benefits, and thus a new shortcut of the income increasing is created for farmers. Compared with the conventional early maturing seedling cultivation mode (low temperature, short-day, etc. ), during the practical production application, the method is not limited by territories, and is easy to implement and master, the early maturing degree is high, and the invested cost is low.
