The invention discLoses a grape soiL-free tank rack cuLtivation method, which comprises the foLLowing steps of: (1) pLanting grape seedLings aLong the center Line of a cuLtivation tank; (2) after theseedLings sprout, keeping 2 main branches, wherein the main branches are fLattened LongitudinaLLy aLong the centraL Line direction of the upper opening of the cuLtivation tank, the pinching is carriedout on the main braches when the main branches grow to the middLe point of two grape pLants, and the pinching is aLso carried out on the LateraL branches with 6 to 7 Leaves kept; (3) appLying organicfertiLizer into the cuLtivation tank and watering in September-October; (4) cutting the LateraL branches with two sprouts Left to form canes after the Leaves of the grape pLant faLL; (5) after sprouting, seLecting and keeping one branch with spicae from the canes as a bearing branch, wherein the bearing branch is hung on two sides of the cuLtivation tank rack, the pinching is carried out on the top of the bearing branch, near the ground, and the pinching is carried out on the upper LateraL branch of the bearing branch with one Leaf Left; (6) after the grapes are harvested, appLying base fertiLizer into the cuLtivation tank and watering; (7) after defoLiation, cutting the bearing branch with two sprouts Left to form a cane. According to the invention, the fertiLizer and water can be accurateLy controLLed; the yieLd of the fruits is improved; the occupied space is smaLL.
