Passion fruit planting technology Passion fruit should be planted in February-March every year. The economic cultivation cycle of passion fruit is generally 4-5 years. After harvesting in the fifth year, the old plants should be cut down and completely renewed. Because passion fruit is a tropical fruit, continuous cropping is easy to be infected with viruses, reducing yield and quality. In order to reduce the harm of virus infection to passion fruit, it is best to update it every year and plant it with virus-free healthy seedlings.

1, the planting distance of passion fruit is vine fruit tree, and the branches extend. Therefore, the row spacing of trellis cultivation is 3m, the plant spacing is 3-3.5m, with about 70 plants per mu, the row spacing of single-row hedge cultivation is1.7-1.8m, and the plant spacing is 3.5-4m, with 100 plants per mu.

2. Planting method: according to the predetermined planting distance between rows, dig a planting ditch with a width of 60 cm and a depth of 20-30 cm, first put mixed compost or other soil miscellaneous fertilizers, and at the same time add 0.25 kg of phosphorus +0. 15-0.25 kg of compound fertilizer to each plant, and then pile it up for planting. After the plant survives, the axillary buds should be pulled out at any time, leaving only the terminal buds of the main vine.

3. Scaffolding: During passion fruit planting, scaffolding must be set up for management and harvesting. At present, there are many forms of scaffolding, mainly horizontal scaffolding and single-line fence scaffolding. Single-line fence scaffolding columns are 2.3 meters high and set between plants. Plant about 30 cm underground, and pull two rows per column 12.

Planting conditions of passion fruit

1. Soil: Passion fruit has strong adaptability and low requirements for soil. Sandy loam, red loam, kaolin and other well-drained flat land or sloping land can be planted, and it is absolutely not allowed to be planted in places with long-term low-lying water accumulation. In large-scale production, it is best to plant in fertile soil, loose soil and well-drained places, and paddy fields with irrigation and drainage are the best. The most suitable soil pH value of passion fruit is 5.5-6.5. When pH < 5.5, the acidity is too high, which is easy to cause stem rot. Therefore, before the arrival of high temperature and rainy season in summer, some acidity should be neutralized with lime to improve the soil. pH value

2. Illumination: Passion fruit likes plenty of sunshine to promote the growth and nutrient accumulation of branches and vines. If there is not enough sunshine, it will grow slowly, branch too much, and even cause the fruit to shrink and fall off. Passion fruit is a diurnal plant with photoperiod effect, that is, long sunshine hours (more than 12 hours) can promote the formation and flowering of flower buds. Generally, water and fertilizer can be cultivated and managed after sowing in early spring.

3. Temperature: Passion fruit basically has the same temperature requirements as ordinary tomatoes, and has wide adaptability, so it is suitable for planting in the north and south (the north should overwinter in a greenhouse, and the south should be covered with cold protection before the frost period at an altitude of 1400m, so it can safely overwinter, otherwise the upper part and lateral branches of the main stem will freeze to death, or even the whole plant will freeze to death.
