The utility model relates to the technical field of seed
germination, and discloses a multifunctional seed
germination observation box which is characterized in that a planting component is arranged in an observation box body; water is injected into the water collecting tank through the connecting
pipe, and the
water level in the other end of the connecting
pipe can be observed through the transparent scale plate, so that the
water level in the water collecting tank can be known, and the situation that excessive water in the water collecting tank overflows, and water enters the observation box body is avoided; meanwhile, the height of the
water level in the water collecting tank can be obtained through a transparent scale plate, and growth of seeds in the transparent planting box is prevented from being affected by water shortage of the water collecting tank; the sliding column is pushed to move in the sliding groove, so that the sliding column drives the measuring scale to move to the position of a seed, an observer can measure the length of the
rhizome of the seed by looking at the head up, data can be recorded rapidly, and meanwhile when measurement is not carried out, the measuring scale can be used for measuring the length of the
rhizome of the seed by moving the sliding column to the two ends of the sliding groove. The transparent planting box is prevented from being shielded by the measuring scale, and the
sight of observers is prevented from being influenced.
