2. Leveling: Leveling along the direction of greenhouse construction, with the border width of 3m, digging a drainage ditch of 30cm×20cm between the borders, and erecting a ridging box in the middle of the border along a straight line, with the base of the ridging box being 60cm wide, 40-50cm high and the spacing between the ridging boxes being 3.0-50cm.
3. Planting: It is advisable to plant greenhouses in February and March every year. 20-30 kg of decomposed organic fertilizer is applied to each planting hole, and compound fertilizer 1.0- 1.5 kg is used as base fertilizer, and the base fertilizer is covered with surface ripe soil dug out during hole digging, with a thickness of 15-20 cm. Seedlings are planted on mature soil and planted. When planting, straighten out the root system, fill the soil in layers and compact it. The root neck of the seedling is 8- 10cm higher than the planting surface to ensure that the joint is exposed to the soil surface, and water it in time after planting. The planting spacing is 3.0m×3.5m, with 60-70 plants per 667m2 species.
4. Bud smearing: After the survival of field planting, axillary buds should be removed in time to make the main vine grow fast and stout, and smeared for 5-7 days 1 secondary bud.
5. Leading vines: When the main vines grow to 40-50cm, the pillars should be inserted in time to guide the main vines to the shelves. When the main vine is put on the shelf, the side vines should be dragged and grown on the wire rack all the time. After the lateral vines are full, the top is broken. Lateral vines tend to have one branch on each side, which is beneficial to early fruiting.
6. Shaping: The main vine and the lateral vine are the main vegetative branches, and the secondary lateral vine grown by the lateral vine is the main fruiting branch, so cultivating strong fruiting vines is an important part of increasing production. When the main vine grows to the height of 1.5m, let it grow lateral vines and grow to both sides.
7. Pruning: Don't cut passion fruit any more. If it is excessively pruned, the main vine will wither gradually, and the whole plant will die in severe cases. Generally, after each batch of fruits is ripe and picked, 2 or 3 knots should be cut off in time to promote the lateral vines to grow again. In summer, the branches and leaves that grow too densely and droop must be thinned to maintain good light and ventilation, and the drooping branches should be cut off at 30-40cm from the ground. After harvesting the last batch of fruits in winter, cut off all fruiting branches from the base to prevent white growth or too dense branches and leaves in the next year.
8. Weeding: Before the fruiting mother branches are full, weed the orchard irregularly to prevent weeds from competing with young trees for fertilizer and breeding pests and diseases. Weeds removed can be buried in deep ditches in planting areas, or they can be removed from orchards and burned.
9. Scientific water management: Passion fruit is drought-tolerant, but too dry soil will affect the development of vines and fruits. In severe cases, branches will wither, fruits will not develop and fruit will drop, so irrigation is needed when the soil is white and dry. Pay attention to drainage in rainy season to prevent water from causing root rot.
