A kind of offer plantation cultivates to plant and plants and when seedling, provide nutritional ingredient, fertilizer or the feedway for being suitble to its nutrient in due course； Including one have by design unequal thickness and bottom present it is gradient can charging main body easily in what insertion soil, it is able to the upper cover for covering and clasping or lock and there is mark at obvious place outside with a cooperation charging main body, the mark of upper cover is to be directed toward planted plant. The main body and upper cover of the present apparatus are all that → fermentation → processed using plant amylum and celloglobulin goes water → polymerization → to be recrystallized into high molecular polymer as material, this material can in the soil the watering by the microorganism in soil and when imposing plantation and reach complete decomposition； Thereby form a kind of supply plant growth fertilizer control device.一種提供種植、培育植栽和種苗時，適時提供營養成分、肥料或適合其養分之供給裝置；包括一個經過設計而有不平均厚度且底部呈現有斜度可易於插入土壤中之裝料主體，和一個配合裝料主體得以蓋上和扣住或鎖住並在外面明顯處有標示的上蓋，上蓋的標示是用以指向所種的植物。本裝置的主體和上蓋都是以植物澱粉和纖維蛋白質經加工→發酵→去水→聚合→再結晶成高分子聚合物為材料，此材料可在土壤中由土壤內的微生物和施以栽種時的灑水而達到完全分解；藉此組成一種供給植物成長肥料控制裝置。
