A kind of seedling container of high gas flow smooth degree, accommodating unit, a cover unit combined with the accommodating unit comprising one with an accommodating space, and plural filtration members. The cover unit includes one having a roof of plural stomata, plural ventilating column, and the shelves structure in the plural position what grade stomatas. It is connected to corresponding stomata by plural ventilating column, the smooth degree that air-flow can be made to pass in and out the accommodating space is high, sharp what plant growth. Furthermore in high temperature sterilization, swollen in the accommodating space rise gas can smooth outflow it is extraneous, take out when cooling down, ambient atmos smooth can also fill into accommodating space, therefore the seedling container is integrally not likely to produce deformation. Furthermore through the design of the grade gears structure, in high temperature sterilization, the filtration members such as this can be blocked in the what grade ventilating columns, will not fall to the external world because of swollen rise of gas.一種高氣流順暢度之種苗容器，包含一具有一容置空間的容置單元、一與該容置單元相結合的蓋體單元，及複數過濾件。該蓋體單元包括一具有複數氣孔的頂壁、複數通氣柱，及複數位於該等氣孔內的檔制結構。藉由複數通氣柱連通相對應的氣孔，能使氣流進出該容置空間的順暢度高，利於植物生長。此外在高溫殺菌時，該容置空間內的膨漲氣體能順暢流出外界，取出冷卻時，外界氣體也能順暢補入容置空間，故該種苗容器整體不易產生形變。再者，透過該等擋制結構的設計，在高溫殺菌時該等過濾件能被遮擋於該等通氣柱內，不會因氣體膨漲而脫落到外界。
