Columnar tree culture method suitable for high-density cultivation of nectarine in greenhouse

The invention discloses a columnar tree culture method suitable for high-density cultivation of nectarine in greenhouse. The columnar tree culture method comprises the aspects of facility condition and preparation, soil condition and improvement, nursery-grown plant preparation and requirement, planting and water and fertilizer management, trimming method, facility environment control and the like. Combined with the aspects of the growth condition of the high-density cultivation of nectarine in greenhouse, the growth environment control and the like, careful research is carried out, a specific implement scheme is provided, and conditions suitable for the high-density cultivation of nectarine in the greenhouse are provided, so that the survival rate and fruit setting rate of the high-density cultivation of nectarine in greenhouse are improved to a great extent, reasonable control of tree crowns can be realized, and the purposes of high yield and early production are reached.
