Nectarine is planted in a greenhouse, and its area and height are limited. The plastic trimming must adapt to the growth of the greenhouse and the tree structure that can be harvested year after year. Reshaping generally adopts a north-high and south-low slope-type population structure. The northernmost plant has a stem height of 50 cm. The tree shape can be a spindle shape and the tree height is 1.5 meters. The southernmost plant has a stem height of 30 cm. The tree shape is a happy shape. It is 1 meter high; the central trunk height gradually decreases from north to south, and the tree shape is a "Ya" shape with east and west main branches.
Pruning before shed, adhere to the principle of "mainly sparse branches, long stay and long release", thinning out vegetative strong vegetative branches, disease and insect branches, long branches, thinning dense branches, overlapping branches, drooping branches, slender branches Short to middle compound flower bud. Open the main branch and the central stem that are growing upright. For medium and long fruit branches, long extensions are implemented at all extended parts. Generally, the amount of thinning branches does not exceed 10% and the short cuts do not exceed 20%. In order to ease the growth and increase the fruit setting rate, pay attention to maintaining a thickness of about 0.5 cm when thinning branches. The middle compound flower buds have longer mature fruit branches.
