摘要：
Sap-collecting devices, systems and methods for sap-producing saplings are disclosed. The saplings each have at least one stem, which is cut to form a top end at a reasonable height above ground. The sap-collecting system includes a sap-collecting device that fits over the top end and forms a vacuum-tight seal with the stem. The sap-collecting device includes an interior and an access port open to the interior. The access port can be connected to a line system. A vacuum system is operably connected to the line system and forms a vacuum within the sap-collecting device. This serves to draw the sap from the top end of the sapling, through the sap-collecting device, through the line system and to a collecting tank. A plantation growth, management, and sap-collecting system that comprises the sap-collecting system and a stand of saplings is also disclosed.
