The Latest Passion Fruit Cultivation and Management Techniques: A Tutorial
The scientific name of passion fruit is Passiflora edulis, a herbaceous climbing fruit that generally grows in valley forests and can only be planted in tropical regions. The plant is a perennial with a very long lifespan. Besides being edible, it also has certain medicinal value, and its seeds can be pressed for oil. It has relatively high economic value and good cultivation returns, so many regions choose to plant it. High-yield cultivation techniques and post-planting cultivation management are very important, and this is also the main content this article will cover.
I. Cultivation Techniques
1. Site Selection
Passion fruit needs relatively high growing temperatures, so land should be chosen in low-altitude areas for planting; the planting site is best if it is flat, broad, and easy to manage and transport from; the root system is average, so deep, loose, breathable, and well-draining soil should be chosen; it likes fertilizer, so the planting site should be fertile.
2. Planting
In the tropics it can be planted year-round, while in the subtropics it is planted in spring and autumn. Planting requires trellises; generally a small trellis 3 m long and 3 m wide is suitable for planting 10 plants beneath it, not too many, as crowded vines affect photosynthesis and growth. Before planting, each planting pit should be given sufficient base fertilizer and farmyard manure, with a plant spacing of about 30 cm; water thoroughly and cover with rice straw to retain moisture and warmth.
II. Management
1. Fertilizer and Water
Before fruiting, young trees should be given a nitrogen fertilizer topdressing once a month to keep the plants growing well, sprouting and branching, retaining branches, and preparing fruiting branches. Adult trees are given base fertilizer in early spring, applying fertilizer in a ring-shaped trench dug 30 cm from the roots; apply about 2 to 5 jin of farmyard manure per plant, then cover with soil and water to aid absorption. During the fruiting period, a topdressing should be applied once, mainly compound fertilizer diluted with water for quick absorption; after harvest, fertilizer should be replenished, mainly barnyard manure and similar mild fertilizers, to keep warmth and protect the roots. After the second fruiting, another topdressing is applied. The root system is shallow and fears both drought and waterlogging; besides normal watering, drainage must be ensured after rain, as waterlogging easily causes root rot or even death; but a lack of water also causes water loss, slow growth, small flowers, and fruit drop.
⟦NL>2. Pruning
Before budding, heavy pruning should be carried out: generally remove all dead and diseased branches, then keep the main trunk and cut off side branches and twining branches beyond 60 cm. Light pruning can be done in all four seasons; during vigorous growth, remove excess shoots and weak branches; after harvesting, cut off most of the new shoots and keep a few healthy branches at good node positions. Prune branches that have already fruited, as well as diseased, pest-damaged, and dense branches.
3. Pest and Disease Control
The main disease is damping-off, for which a 800-fold dilution of Cudao Likuling or a 800-1000-fold dilution of Miao Jundi can be used; for mosaic disease, a 1000-1500-fold dilution of Xiaoye Huangjue or a 1500-2000-fold dilution of Bingduling can be sprayed for treatment. The main pest is the leaf miner, for which a 1000-fold dilution of 40% dimethoate emulsifiable concentrate or a 1000-1500-fold dilution of 40% diazinon emulsifiable concentrate can be used; for thrips, a 1000-fold spray of 25% imidacloprid or a 3000-5000-fold root drench of 25% thiamethoxam water-dispersible granules can be used.
The above are the cultivation and management techniques for passion fruit. I hope this brings you some help after reading. For specifics, you can learn from experienced growers or accumulate practical experience yourself, so as to gain a comprehensive understanding of cultivation and management.
