The raw water conservation stake of a plant,System prospects instrument using geoscience and surveys out hydrological data in desert terrain,And a plurality of predetermined points according to hydrological data along the desert terrain are implanted into subsurface predetermined depth,To be afforested； Wherein,The raw water conservation stake of the plant is moulded into cross section into H-type shape by organic fertilizer etc.,And run through slot comprising plural vertical direction on cross section； A plurality of twirls twist item,Strip is twisted by water-absorbing material,It is packed in running through in slot for the plural number vertical direction respectively,And each twirl of plural number twirl twirl item is twisted item and is arbitrarily extended to its top outer direction； AndA plurality of plants are planted,It is planted in a plurality of tops for planting raw water conservation stake. Accordingly, a groundwater absorbing and water conservation stake slow release fertilizer nutrient are twisted by the twirl, plants crop using what desert geology to conserve to plant, is apt to limited water resource.一種植生保水樁，係利用地球科學探勘儀在沙漠地形中勘測出水文資料，並根據水文資料沿該沙漠地形之複數個預定點植入地面下預定深度，以進行綠化；其中，該植生保水樁由有機肥料等塑成橫斷面成H型狀，及在橫斷面上包含複數垂直方向的貫穿槽；複數個撚捻條，由吸水性材料撚捻成長條狀，分別填塞在該複數垂直方向的貫穿槽中，且該複數撚捻條之每一撚捻條向其頂部外側方向任意延伸；及，複數個植栽，種植在該複數個植生保水樁的上方。據此，藉由該撚捻條吸取地下水及保水樁緩慢釋放肥料養分，應用於沙漠地質以涵養植栽作物，善用有限的水資源。
