PROBLEM TO BE SOLVED: To provide a plant cultivation container designed so as to reduce pressure applied to soil inside a lower-side container by the weight of an upper-side container or the like, and reduce labor required for root cut work, in a cultivation method where the containers are sequentially superimposed on one another to promote plant growth.SOLUTION: The plant cultivation container (such as a flower pot 10) used for plant cultivation is structured as follows: the upper face of the container is open a plurality of holes (such as holes 11) are vertically formed and root cut holes (such as root cut holes 15) almost perpendicularly intersecting the plurality of the holes are formed in a bottom wall part (such as a bottom wall part 16) and a supporting part (such as a shelf part 13) for supporting other containers superimposed thereon from above is formed on a side wall part (such as a side wall part 12). Such structure of the container results in that the pressure applied to the soil inside the container is reduced and also the root cut work is facilitated. The root cut work results in digesting chemical components such as nitrate ions absorbed from the soil, thereby producing highly safe vegetables having less contents of the chemical components.COPYRIGHT: (C)2010,JPO&INPIT【課題】容器を順次重ねて生育を進行させる栽培方法において、上側の容器等の重さによって下側の容器内部の用土に加わる圧力を軽減させ、かつ、根切り作業に要する労力を軽減させる。【解決手段】植物の栽培に用いる植物栽培用容器(例えば植木鉢10)は、上面が開口し、底壁部(例えば底壁部16)には、上下方向に複数の孔(例えば孔11)が形成され、かつ、この複数の孔と略垂直に交わる根切り孔(例えば根切り孔15)が形成され、側壁部(例えば側壁部12)に、上側から重ねられた他の容器を支持するための支持部(例えば棚部13)が形成されたことを特徴とする。これにより容器内部の用土に加わる圧力を軽減させることができるとともに、根切り作業が容易となる。また、根切り作業を行うことによって、用土から吸収した硝酸イオンなどの化学成分を消化し、化学成分の含有量が少ない安全性の高い植物を得ることも可能となる。【選択図】図3
