The passion fruit temperature requirements are basically the same as ordinary tomatoes, adaptability is broader, adapted to the north and south planting (the north is suitable for over-wintering in greenhouses, the south in the 1400m altitude above the onset of the frost period should be covered with cold weather, in order to be able to safely over-wintering, or else the upper main stem and lateral branches are more frozen withered, and even the whole plant frozen to death)).
1, planting passion fruit planted that year, the output of the year, to the annual February-March planting is appropriate. General passion fruit economic cultivation for 4-5 years, in the fifth year after harvest, the old plants will be cut to fully renew. Because passion fruit for tropical fruits, crop is very easy for virus infection, reduce yield and quality, in order to reduce the passion fruit by virus infection, to virus-free healthy seedlings, the best annual renewal planting.
①Planting distance Passion fruit is a trailing fruit tree, branches and vines to extend, so the trellis-type cultivation with a spacing of 3 meters, plant spacing 3-3.5 meters appropriate, acres of about 70; single-line hedge cultivation spacing 1.7-1.8 meters, plant spacing 3.5-4 meters appropriate, acres of planting about 100 plants.
② planting method according to the scheduled planting of the rows of spacing, dug 60 cm wide, 20-30 cm deep planting ditch, first into a good mix of compost or other fertilizers, at the same time, each plant with 0.25 kg of phosphorus + 0.15-0.25 kg of compound fertilizer, and then up to the pier planting, planting after the survival of the planting, the axillary buds should be readily After the planting has been activated, the axillary buds should be removed at any time, leaving only the top buds of the main vine and tying the vines to the pillars, so that the plants can climb up the trellis as soon as possible.
2, set up scaffolding passion fruit cultivation must be set up during the trellis, in order to manage, harvest. Scaffolding is equipped with a variety of forms, the current horizontal type of scaffolding and single line hedge type frame is mainly. Single line hedge type frame column height 2.3 meters, set up between plants and plants, implanted in the ground about 30 centimeters, each column pull 2 12 lines.
3, pruning and pruning passion fruit planting, in the seedling period should be inserted to set up the pillar, in order to lure the main vine on the trellis, to be the main vine 1 meter high, cut off the top buds, so that it grows out of the lateral trails, each side of the side of the 2 side of the trails, divided into two lateral growth, when the lateral trails up to 2 meters, the lateral trails will be cut off the top of the lateral trails, in order to promote the secondary side of the trails grow. If it is a horizontal trellis cultivation, should wait for the main vine to reach the trellis, stay side vines to the four sides of the average growth. Passion fruit avoid heavy pruning, no need to strong pruning every year. If excessive pruning, easy to make the main vine gradually withered, and in severe cases, the whole plant died. Generally after each batch of fruit harvest, each side of the vine to stay 3-4 sections for short cuts, and promote its re-growth of lateral vines, at the same time, every summer must be pruned overgrowth of dense branches, or will be hanging down to delay the ground branches, from the ground about 20-30 cm to cut out, in order to keep the ventilation is good.
4, fertilization Passion fruit fertilization principle to nitrogen, phosphorus, potassium ratio of 2-1-4 appropriate, avoid over-application of partial application of nitrogen fertilizer. In order to promote early birth and fast development, 7 days after the seed began to shower 2 times love more collection, 7 days apart, each sachet to 60 kilograms of water. 15 days after flowering is a period of rapid fruit expansion, should strengthen fertilizer management, especially to increase the application of potash fertilizer, promote rapid fruit expansion.
5, water management passion fruit is more drought-resistant, but in case of drought, irrigation is still required. Soil is too dry, will affect the vine and fruit development, serious branches show withered, fruit does not develop and will occur fruit drop phenomenon. During the rainy season, pay attention to drainage.
