To make water uniformly stream down to a basket on the lowermost stage when water is sprinkled to baby plants in the baskets being stacked in several stages by providing notched grooves which cross the longitudinal direction of ribs on the upper end side of the numerous ribs for the baskets made of a synthetic resin.

For the bottom section 1 of this basket, through holes 8 are formed by providing linear ribs 4 into a grid-shape, and notched grooves 7 which cross the longitudinal direction of the linear ribs 4 are provided extending to the total periphery of the linear rib 4, on the linear ribs 4. The notched groove 7 is provided on respectively linear ribs 4 on circular orbits which alternately continue under a state wherein the circular orbits are parted by the through holes 8, and the bottom section 1 is partitioned P into a plurality within a specified range. In addition, a leg section is provided on the external edge of the bottom section 1. The leg section is located to be slightly closer to the center of the bottom section 1 than the internal surface side of a side wall section 2, and is shallowly fitted in the basket on the lower stage side when the baskets are stacked. By this constitution, water can be made uniformly stream down to the baskets on the lower stages, and nursery plants housed in the baskets can be evenly grown.
