1, reasonable close planting. The open planting density is 2 m× 1 m, the line spacing boundary of the first 1 row is 1.5 ~ 2 m, the line spacing of the second row is 2 m, and the line spacing of the third row is 3 m. From the third row, there is a line spacing of 1 3 m every 2 m, and so on.

2. The planting density in the facility is1.5m× (1~1.2) m, and the number of rows is designed according to the shed width and the support. Attention should be paid to the design: First, the distance between the shed leg and the side row is the row spacing divided by 2 plus 0.5 m, so as to avoid the plastic surgery being affected by the insufficient height of the shed side. Second, for greenhouses with supports, they must be planted along the supports, and both sides of the supports should be planted as appropriate. Whether it is an arch shed or a greenhouse, we should pay attention to the north-south shed and the north-south shed, the east-west shed and the east-west shed, so as to facilitate micro-tiller farming and plastic film mulching. Before planting, sufficient base fertilizer should be applied, and the soil should be prepared and ridged. Planting in autumn is better than deep planting. Cover with water and film after planting.

3. Scientific shaping and pruning. Prune 1 year after planting, and dry immediately after planting. The height of the stem is about 50 cm. The incision is about 0.5 cm away from the bud, and there must be a full bud under the incision. Cut off the plastic cloth at the marriage seam and the sprout under the marriage seam. Summer scissors (usually in early May) ① The first 1 summer scissors. When the new branch grows to about 20 cm, the topmost new branch is not cut (if the topmost new branch is weak, all branches are cut, and the second strongest branch is not cut), and the rest branches are cut short by 5 ~ 6 cm.

4. If the trunk is crooked, the tree will be in disorder. When the trunk length is about 1 m, it is necessary to straighten the trunk with a bamboo pole of about 2.8 m, and the rope tied to the trunk should not be too tight to avoid injury to the trunk. With the increase of trunk, it is usually tied 3 ~ 4 times. In the process of plastic surgery, if the pear moth bites off the new tip of the trunk, the newly grown branches will be lifted up again with the trunk, and other branches near the trunk will be cored or chopped.

5. Winter pruning is pruning after defoliation. The purpose of pruning is to make the tree even, ventilated and transparent, and to determine the yield and the number of branches. Sparse the branches below; Too many sparse branches, especially the strong branches in the middle and upper parts; Thinning out over dense branches (removing intermediate branches) and damaged branches; The short section does not have a sufficiently high trunk extension head (0.5 cm above the full bud). The average 1 year-old tree has about 25 branches.

6. Pruning of fruit trees after fruit picking. Pruning peaches in greenhouse first cuts the bottom side branches into a single axis, and then leaves a short section of 50 ~ 60 cm. Leave 3 ~ 4 side branches and remove more. Pruning should be carried out in two stages, cutting off 70% ~ 80% of the lower part of the trunk first, 10 d, and then cutting off the rest of the upper part of the trunk, so that on the one hand, the upper part is not forced, and on the other hand, the coordination of the growth of the aboveground part and the underground part is taken care of. If paclobutrazol is too heavy to sprout new branches after short cutting, spray Bihu (1 g+ 15 kg water) or gibberellin (1 g+ 15 kg water) every 7 ~ 8 d and dissolve it with alcohol for three times.
