Greenhouse nectarine dormancy management
First, picking leaves to promote sleep in late October to early November, remove the leaves that grow on the tree and force the nectarine tree to sleep. Second, the pruning of young pruning trees to plastic surgery, choose to cultivate the backbone, expand the crown. Moderately light-cut long-distance release, open angles, balanced tree vigor, promote premature birth; early fruit tree pruning is mainly to cultivate large and medium-sized branch groups to prevent excessive extension. Long fruit branches and fruit branches with a length of less than 40 cm should be clipped or slowly placed, and the fruit should be retracted when the result is drooping at the back. The short and medium fruit branches do not cut, and the useless standing erect branches, dense branches and diseased shoots are eliminated; the pruning of the fruit stem branches of the fruit tree is aggravated as the growth weakens. The results of the pruning of the branches were noted as updated, moderately short cut, sparse canopy. III. Pest Control After the tree is trimmed, 5 degree lime sulfur is sprayed in the greenhouse once again, which is effective for the control of nectarine bacterial perforation, leaf spot, scale insect, and red spider. Fourth, cover film curtain in the late autumn and early winter, when the night temperature dropped to about 7 °C when the buckle shed, while covering the insulation layer. Open the tuyere at night to allow cold air to enter, close the tuyere during the day, and cover the insulation to keep it cool. After 30 to 40 days of such maintenance, the nectarine can pass through the dormancy period.
