Detailed Guide to Passion Fruit Planting Methods and Cultivation Techniques
Passion fruit is a perennial evergreen climbing woody vine of the genus Passiflora in the family Passifloraceae, also known as maypop, Brazilian fruit, passion fruit, and running-heart lotus. It originated in Brazil and was later cultivated in South America, South Africa, Southeast Asian countries, Australia, and various regions of the South Pacific. In China, it is cultivated in Guangxi, Jiangxi, Sichuan, Yunnan, and other places. Let us now take a look at the cultivation techniques for passion fruit!
Growth Habits of Passion Fruit
Passion fruit originated in South America and is commonly cultivated in tropical and subtropical regions. It is a tropical and subtropical fruit that prefers bright light, sunny locations, and a warm climate. It has strong adaptability and is not demanding about soil. It can be planted in front of and behind houses, on hillsides, and along roadsides, but grows best in sunny garden plots that are rich in organic matter, loose, deep in soil layer, well-drained, and exposed to ample sunlight. It dislikes waterlogging and is not drought-tolerant, so the soil should be kept moist.
Cultivated Varieties of Passion Fruit
1. Purple-fruited type: The purple-fruited type of passion fruit has purple-red skin and greenish vine stems. It is suitable for planting in places with cool summers at elevations of 300 to 500 m, but is not suitable for cultivation in the Pearl River Delta or areas to its south where summer temperatures are high.
2. Yellow-fruited type: The yellow-fruited type of passion fruit has strong adaptability, larger fruit, higher yield, excellent quality, and a higher juice yield, but it has poorer cold tolerance. Some varieties also exhibit self-incompatibility and require artificial supplementary pollination.
Propagation Methods of Passion Fruit
1. Sowing: Seed propagation can be carried out throughout the year, but sowing in spring and autumn is best. Generally, robust, pest- and disease-free, high- and stable-yielding plants are selected as mother plants. Fruits that are well-shaped, slightly heavy, and fully ripe are harvested, the seeds are extracted, washed to remove residue, and dried before sowing. When sowing, mix 1 kg of seeds with 10 to 20 g of carbendazim for about 20 minutes, then evenly broadcast the seeds on the seedbed, cover with a thin layer of grass, water thoroughly, and transplant when the seedlings grow 4 true leaves.
2. Layering: Layering propagation is best done in spring from February to March. The method involves pressing branches from the mother plant into the soil or wrapping them with soil and other materials to form adventitious roots, then separating the branches above the adventitious roots from the mother plant to form an independent new plant. During layering, to interrupt the downward transport of organic substances such as sugars, auxins, and other substances from the leaves and upper branches, so that these substances accumulate in the upper part of the treated area for use during rooting, ring-barking can be performed.
3. Cuttage: The best time for cuttage is spring from February to March, and autumn cuttage is also possible. Select robust, mature one-year-old vines as cuttage material. After cutting the cuttings, soak them in a 25 mg/kg aqueous solution of Abr rooting powder for 30 minutes, then insert them into nutrient bags 8 cm in diameter × 12 cm in height for cultivation. The insertion depth should reach 2/3 of the cutting length. It takes about 3 to 4 months from cuttage to leaving the nursery.
Planting Methods for Passion Fruit
1. Soil: For passion fruit planting, sandy loam soil that is fertile, loose in texture, and well-aerated should be selected. Heavy clay soil, compact sandy soil, cold sandy soil, and areas prone to erosion are not suitable for planting unless improved. The soil pH should preferably be neutral to slightly acidic below pH 7.0.
2. Field planting: When planting passion fruit seedlings, old leaves should be properly pruned off, and the nutrient bag should be broken open and removed, not buried in the soil. When setting the seedlings, mix an appropriate amount of decomposed organic fertilizer with sandy loam soil to make planting soil or covering soil. When planting, straighten the root system, fill soil in layers, and firm it by treading. Water the roots promptly after planting. For newly dug planting holes, the seedling root crown should be about 8 to 10 cm above the ground surface when planted. After planting, shape a tree basin and cover it with a small piece of film measuring 50 × 50 cm.
2. Fertilizer and water: When passion fruit is first planted, base fertilizer application should be combined with hole digging and planting. Apply 10 to 15 kg of decomposed farmyard manure per hole, backfill the hole with soil, and then plant. After fruit harvest each year, apply sufficient base fertilizer in combination with pruning and weeding, applying 8 to 10 kg of decomposed organic fertilizer per plant. Topdressing for passion fruit is generally carried out after field planting and survival, once a month, first dilute and then concentrated, with thin manure water being preferable.
3. Vine training: When young passion fruit trees grow to 40 to 50 cm, supports should be set up promptly to guide the young vine stems onto the trellis. When the main vine of the young tree grows to 70 to 80 cm, retain 2 side vines and guide them separately onto the trellis as the first layer of main vines. When the plant grows to 150 to 160 cm, retain another 1 vigorous side branch to serve together with the extended main vine as the second layer of main branches, guiding them in opposite directions onto the trellis to form a double-layer, four-branch vine training system.
4. Flowering: Passion fruit flower buds belong to the current-year differentiation type, shooting and differentiating at the same time. From flower bud differentiation to flowering takes only about 30 days. Newly planted cuttage seedlings in the same year can flower by June, and a small amount of fruit is available on the market by August. The second year enters the formal fruiting period, and flowering can occur multiple times each year from March to November. Each node on the base of the flowering branch section can form 1 flower, and in production, 4 to 6 normal flowers can form continuously, after which normal developed flowers can form every 2 to 3 nodes.
5. Fruiting: The time required for passion fruit to mature varies with the flowering season. Flowers opening in May to June mature 50 to 60 days after flowering; flowers opening in August to September require 70 to 90 days to mature; flowers opening after October require 100 to 120 days to mature. Its self-pollination fruit-setting rate is high, and mature fruits can be picked from mid-June each year to early February of the following year, with the most concentrated harvest periods in early July and late October.
Cultivation Methods for Passion Fruit
Passion fruit is a plant of the genus Passiflora in the family Passifloraceae. The genus has more than 400 species, most native to the tropical regions of the Americas, and 13 species are native to China. They prefer bright light and a warm to hot and humid climate, and are not cold-tolerant. They grow quickly, have a long flowering period, and produce abundant flowers, making them suitable for planting in areas south of 24 degrees north latitude.Although the requirements for soil are not very strict, to obtain high and stable yields, a growing environment with loose and fertile soil, rich organic matter, sufficient water, good drainage, and convenient irrigation is required. In terms of climatic adaptability, warm weather without freezing damage throughout the year is required.
Passion fruit is a vine fruit tree. To achieve good growth, abundant fruiting, and few pests and diseases, trellis cultivation is essential. At present, passion fruit planting generally uses two types: overhead trellis and fence trellis. These two trellis types each have advantages and disadvantages.
The advantage of the overhead trellis is that in dry land, sloping land, and dry seasons where water sources are relatively scarce, it can shade the ground, reduce evaporation, and form a small environment with relatively high humidity under the trellis, while also making full use of the abundant bamboo and wood resources in some areas to reduce the cost of building the trellis; its disadvantages are that the effective green leaf layer is thin, the fruiting capacity is relatively small, the yield is relatively low, and pruning, pest control, and disease prevention spraying are more difficult. In paddy fields or passion fruit flowers
during the rainy season, orchard humidity is relatively high, which easily induces disease. At the same time, when fruits mature, many fruits remain on the trellis surface and do not fall to the ground in time, which is unfavorable for fruit harvesting. The advantages of the fence trellis are that it facilitates shaping and pruning, pest control spraying, artificial supplementary pollination, and fruit harvesting, while also having a thick effective green leaf layer, large fruiting capacity, and reasonable ventilation and light exposure; its disadvantage is that more iron wire is needed to build the trellis.
At present, according to the principle of high efficiency and low cost, the use of a single-wire fence trellis is advocated, that is, only one wire is stretched at the top of the fence trellis posts, and the main vines of passion fruit grow along the wire. The wire specification is No. 8 or No. 10. If the posts are relatively dense, such as setting 1 post every 1 plant, then No. 12 wire can be used. The wire should be 1.8 m above the ground, and the posts or supports should also be more than 1.8 m high, so as to fully and rationally utilize space and light energy.
The posts and supports used for trellising can be reinforced concrete posts, wooden posts, or bamboo posts, depending on the actual conditions of each orchard. Reinforced concrete posts are durable but cost more, while wooden or bamboo posts cost less but have a shorter service life. A compromise is to use reinforced concrete posts together with bamboo or wooden posts, alternating the posts.
This can combine the advantages of low cost and durability. From a comprehensive analysis of high and stable yield, convenient cultivation management, and trellis construction cost, the use of the single-wire fence trellis type for cultivating passion fruit is advocated.
