It also contains many minerals and free amino acids which are beneficial to human body. While it has the pleasant aroma of pineapple, banana, mango, guava, apple, sour plum and other fruits. Because of its strong aroma and high acidity, it is known as the king of natural fruit juices and natural spices. Passion fruit with its unique flavor, product market prospects.
A、Passion fruit requirements for environmental conditions
The most suitable temperature for the growth of passion fruit is 20 ℃ ~ 30 ℃. Generally in the temperature conditions not less than 0 ℃ grow well. To -2 ℃ when the plant will be seriously affected, or even die.
General annual rainfall between 1500-2000 mm and evenly distributed under the conditions of the best growth of passion fruit. Commercial development of planting areas of annual rainfall should not be less than 1000 mm.
As a tropical fruit, passion fruit like full sunlight. This can promote the growth of branches and vines and nutrient accumulation. Long sunshine time is conducive to the flowering of it. While in the annual sunshine hours 2300-2800 hours of the region, passion fruit growth, nutrient accumulation, rapid growth of branches and vines, early results, fruitful.
Passion fruit is highly adaptable, the soil requirements are not high. However, the large-scale production of it, soil layer of at least 0.5 meters, and the soil should be fertile, loose, well-drained. The most suitable soil pH value is 5.5-6.5.
B、The variety of passion fruit selection
Now widely planted passion fruit have purple passion fruit, yellow passion fruit and hybrids and so on. However, the natural pollination fruiting rate of about 10%-29.6%. The purple introduced from the United States Hawaii, natural pollination rate of 60%, and high sugar and vitamin C content, strong aroma, high yield. Planted in the year of harvest, the third year of peak yield can reach 2000 kg per mu.
C、The establishment of passion fruit orchards
1、Lelection of land and reclamation
Passion fruit planting site is appropriate to choose a well-drained gently sloping land. The soil is deep, fertile and loose sandy loam soil is more suitable, can be reclaimed or hole reclamation. If planting it in mountainous areas, require planting bandwidth of more than 1.1 meters, inclined 50-80, planting the outer edge of the belt to build a small ridge 20 cm high and 30 cm wide.
2、Build the frame
Passion fruit for sprawling plants, rely on scaffolding support to grow properly. Shelf type has a flat roof type, fence type, “human” and “door” type. The general height of the trellis is 1.8-2 meters. The trellis material can be chosen from cement pillar, stone pillar, wooden pillar and bamboo pole, wooden pole, iron wire, etc.
Passion fruit tree spacing of 4 × 6 meters, 25 plants per mu. Digging holes for planting, the size of 60 × 60 × 60 (cm). Base fertilizer, 25 kg of farmyard manure per hole, 0.5 kg of phosphorus fertilizer. Passion fruit can be planted all year round, planting selected cloudy days or sunny days after the rain, planted after drenching, insulation.
D、The passion fruit orchard management
Newly planted passion fruit, predominantly nitrogen fertilizer. This can promote plant growth. Planting 10-15 days after the root system began to grow, you can apply 0.5% dilute urea or dilute manure and urine. After that, apply 5 kg of well-rotted human manure and urine or 0.1 kg of compound fertilizer every 20 days. We usually use the compound fertilizer produced by Nagric. Each year, we apply 20-30 kg of farmyard manure, 0.6-0.7 kg of urea, 0.6-0.9 kg of phosphate and 1.2-1.3 kg of potash per plant. Farmyard manure and phosphorus fertilizer composted and rotted before and after spring ditching, urea and potassium fertilizer during flowering and fruiting once a month, 0.3-0.4 kg of mixed fertilizer per plant.
Passion fruit is a shallow-rooted plants, like moist, both avoid water and fear of drought. Therefore, the first step is to open a good drainage ditch to prevent waterlogging in the orchard. At the same time, lay weeds to retain water, 15 days without rain to consider irrigation once.
After clearing the garden in winter to carry out the national turn soil, turn the soil combined with buried in the clearing of weeds and residual leaves. Then withdraw 25-30 kg of lime per mu.
Passion fruit is more drought-resistant. However, if you encounter dry weather, still need irrigation. Soil is too dry, will affect the vine and fruit development. In severe cases, the branches show withered, the fruit does not develop or even drop fruit. While in the rainy season, pay attention to drainage.
E、Passion fruit tree plastic pruning
1、Plastic surgery to guide the main vine on the shelf
Passion fruit tree seedlings to resume growth, every 5 days to wipe 1 bud, to promote the main vine quickly, thick. At this time, should insert a pillar to guide the main vine on the shelf. While after the main vine is on the shelf, the side vines should be often guided to grow in a spiral on the wire frame, and after the side vines are full, the top is broken and tied. Side vines to one side of a branch, to facilitate the early development of fruit-bearing branches full frame.
The branch tips sprouted after the previous year’s fruit picking, almost in the middle of each section above the fruit-bearing vine. The previous year to keep as many fruit-bearing branches as possible, but in order to prevent the shed surface is too dense, pruning as soon as possible after fruit harvesting. According to 2 main branches to keep vine, near the main stem of the branch first full of fruit, mature fruit harvest, immediately pruned to 2-3 nodes, from the base of the main branch and then sprouted buds can form new fruit-bearing branches. Winter after the last batch of fruit harvest, all the fruiting branches from the base pruning.
F、The passion fruit pest and disease control
1、The main diseases and prevention
Passion fruit’s main diseases are seedling burst disease, foliar disease, epidemic disease, stem-based rot.
① Soil selection
To choose clean soil seedlings, keep the field moist degree. In particular, it is necessary to prevent the soil from being too wet, away from bananas, various melons and eggplant vegetables.While Remove and burn diseased branches and leaves in a timely manner.
Choose Bordeaux solution or ethyl phosphorus aluminum, anti-killer, etc.
2、The main insect pests and control
The main insect pests of passion fruit are small fruit fly, mites, moths and so on. Trichlorfon, Nongdile, Roxburn, mites that die, etc.
