The temperature at which passion fruit is planted is critical, so how many degrees is it appropriate

The best temperature should be around 20 or 30 degrees, but not below 15 degrees. Otherwise, it will stop growing.

The most suitable growing temperature for passion fruit is 20 30, which should be strictly controlled and should not be lower than 15.

Different varieties of passion fruit have different temperature requirements, but generally speaking, the most suitable temperature is around 25 degrees. During the sowing period, the temperature should be controlled at about 14 degrees. Sufficient light can promote the growth of passion fruit plant shoots, enhance photosynthesis, and increase the accumulation of photosynthetic substances.

Before and after flowering, it is recommended to apply compound fertilizers with a high potassium content or water-soluble fertilizers to improve the quality of the flowers.

Choose to plant in March or September, as passion fruit is the best to survive during these two times.

The most suitable growth temperature for passion fruit is 20 30, generally not less than 0 temperature to grow well, to -2 when the plant will be seriously damaged, or even die.

Generally, passion fruit grows best under the condition that the annual rainfall is between 1500 and 2000mm and evenly distributed, and the annual rainfall in the planting area should not be less than 1000mm.

When planting passion fruit, it is necessary to scientifically control the temperature, scientific watering and fertilization, and apply more nitrogen fertilizer, nitrogen fertilizer can promote the absorption of nutrients by plants, which is conducive to the growth and development of crops.

First of all, we must keep the passion fruit in sufficient sunlight, and also apply fertilizer to the passion fruit, so that the passion fruit has sufficient nutrients, so that the passion fruit can produce very good quality.

1. Build a shed: If you want to let passion fruit spend the winter outdoors, you can use plastic film to build a greenhouse, which is a somewhat troublesome but better way to keep out the cold. On a sunny day, it needs to be opened for ventilation and light, and it should be covered at night.

2. Wrapping: When it is cold in winter, you can wrap the root and trunk of passion fruit with plastic sheeting. And water it less and see more sunlight.

3. Sprinkle lime: Generally, when potting and breeding, the cold method is to sprinkle some lime in the pot. It is also possible to use weeds, films, etc. to protect against the cold. If you spend the winter in the third year, you can cut off some old branches, but if you don't prune, it won't have any effect.

The temperature suitable for its growth is about 20 30, under normal circumstances, as long as the temperature of wintering is above 0, it can survive the winter smoothly. However, if the temperature is below -2, it will be difficult for it to resist the invasion of cold air and will most likely freeze. If you are exposed to low temperatures for a long time, you may freeze it to death.

Usually, it is easy to keep a pot plant for the winter, because when the temperature drops, it can be raised in the house.

1. Outdoor wintering methods.

1.Build a shed: If you want passion fruit to spend the winter outdoors, you can build a greenhouse with plastic film.

It's a great way to protect against the cold, albeit troublesome. When it is sunny, you need to open the windows for ventilation and lighting, and cover them at night. 2.

Wrapping: When it is cold in winter, you can wrap the roots and trunk of passion fruit with plastic sheeting. Water less and get more sun.

3.Sprinkle stone Qiqing ash: Generally, when potting, the way to keep out the cold is to sprinkle some lime in the pot.

Weeds, movies, etc. It can also be used to protect against the cold. If you spend the winter in the third year, you can cut some old branches, and it doesn't matter if you don't cut them.

Second, the overwintering temperature.

The suitable temperature for its growth is about 20 30. Under normal circumstances, as long as the overwintering temperature and selling divergence is above 0, it can be successfully wintered. But if the temperature is below -2, it will be difficult to resist the invasion of cold air, and the very middle Ponzi may be frozen.

Prolonged exposure to low temperatures may freeze it to death. Usually, it is easy to pot it for the winter, because when the temperature drops, it can be kept indoors.

Passion fruit 20 30 As a result, if the temperature is above 30 or below 15, the overall growth of the plant will deteriorate. Cultivation method: Prepare soil, which can be mixed with garden soil, humus soil and river sand soil to make a substrate for cultivation; For seed selection and germination, it is necessary to select the seeds with round and full particles and large size and put them in warm water to soak and germinate; The sowing method is to spread the seeds evenly on the surface of the soil and cover it with a layer of fine soil.

Passion fruit is a common tropical fruit, when the temperature is stable at 20 30, it can bear fruit smoothly, suitable for growing in areas with an average annual temperature of more than 18, the temperature is higher than 30 or lower than 15 will lead to poor growth, can not flower and bear fruit normally. It can be cultivated in Guangdong, Guangxi, Fujian, Yunnan and other regions.

1. Soil preparation

When cultivating passion fruit, we must first prepare the soil suitable for growth, choose loose and breathable, nutrient-rich soil as the substrate for cultivation, in the process of soil blending, the pastoral soil, humus soil, river sand soil can be mixed into the cultivation substrate slag file according to the ratio of 2:3:2, before cultivation, it is necessary to mix the organic fertilizer such as burning the appropriate amount of rotten organic fertilizer to improve the fertility of the soil, and it can be used after 3 5 hours of exposure.

2. Seed selection and germination

When planting passion fruit, the seeds are first germinated to improve the germination rate after sowing, the seeds with round and full grains and larger size can be selected, soaked in warm water of 50 for 1 day, and then wrapped in wet towels to promote germination, and then placed in a ventilated and warm environment, and then the seeds can be sown after they are completely exposed.

3. Sowing method

When sowing passion fruit, it is necessary to evenly sow the whitish seeds into the soil, cover it with a thin layer of fine soil, and water an appropriate amount of water to keep the soil in a slightly moist state. Under the premise of a suitable environment, the seeds will germinate in about 1 week, during which the weeds around the plot can be properly ventilated and ventilated, so that the nutrients can be concentrated for the seedlings to grow.

Summary. The most suitable growth temperature for passion fruit is 20 30 (15 25 for some varieties), the growth is slow when it is above 30 or 15 20, and the growth basically stops when it is below 15, and there is no obvious cold damage found at 12 8 low temperatures, and the young shoots below have a slight cold damage, and the leaves and vine shoots dry up at 5 o'clock, and the frost below 0 will cause the crown to die. The low temperature that the purple fruit variety could withstand was only a slight frost damage in the young tissues of the autumn shoots, and the cold tolerance of the yellow fruit variety was not as good as that of the purple fruit variety. Passion fruit seedlings are not cold-tolerant, and they need to be insulated for planting in northern areas.

Passion fruit is more resistant to advection low temperature, radiation resistance to low temperature is poor, frost is easy to cause damage, frost heavy aboveground dry up and die. In the high temperature and dry season, passion fruit grows slowly, the leaves turn yellow or wrinkled, the stress resistance is reduced, and some plants are diseased in the stem or stem base, resulting in the death of the whole plant.

The most suitable growth temperature for passion fruit is 20 30 (15 25 for some varieties), the growth is slow above 30, or 15 20, the growth of the basic litter stops growing below 15, 12 8 low temperature no obvious cold damage is found, the following shoots appear slight cold damage, 5 hours the leaves and vine shoots dry up, and the frost below 0 will cause crown death. The low temperature that the purple fruit variety could withstand was only a slight frost damage in the young tissues of the autumn shoots, and the cold tolerance of the yellow fruit variety was not as good as that of the purple fruit variety. Passion fruit seedlings are not cold-tolerant, and they need to be insulated for planting in northern areas. The rapid return of passion fruit is more resistant to advection low temperature, and the low temperature resistance to radiation is poor, and frost is easy to cause damage, and the aboveground part with heavy frost is dry and died.

In the high temperature and dry season, passion fruit grows slowly, the leaves turn yellow or wrinkled, the stress resistance is reduced, and some plant stems or stem bases are diseased, resulting in the death of the whole plant.

The lowest temperature that passion fruit can withstand is 2.

The most suitable growth temperature for egg fruit is 20 30, generally growing well at a temperature of not less than 0, and the plant will be seriously damaged or even killed at 2 o'clock, and the area with an average annual temperature of more than 18 is the most suitable for planting, and it is easy to obtain a bumper yield. Therefore, it is widely distributed in the warm and humid areas of southern China, especially Hainan.

Passion fruit, scientific name passionflower, is a perennial evergreen vine fruit tree, is a tropical endemic fruit, unique flavor, rich fragrance, has the fruit "king of beverages" reputation. Passion fruit has a wide adaptability, which is not only suitable for orchard planting, but also can be cultivated in courtyard greening. The fruit of planting in the current year, the yield per mu is more than 2500 kg, and the income can be continuously increased for about ten years.

1. Growth habit passion fruit is suitable for planting in areas with a minimum temperature of 0 or more in winter, and flowers begin to bloom in February and March in the southern region, while growing and flowering, and there are basically fresh fruits ripe throughout the year. In areas where the temperature is below 0 in winter, it is necessary to use greenhouses to protect the land. It can also be moved to the plastic greenhouse in winter, and moved to the open field before and after the Qingming Festival.

2. Choose a plot with convenient drainage and irrigation, deep soil, loose and breathable and fertile land for planting. According to the row spacing of 3 4 meters (about 55 plants per mu) dig holes and plant.

3. Erection The frame shape can be a fence, scaffolding, T-shaped frame or simple bamboo pole support, etc., similar to grapes. Large trellises can be selected for garden planting.

4. Pruning and pruning After planting, select 1-2 main vines to be on the shelf, topping when about 2 meters long, promote the development of secondary shoots, and select 4-6 first-class secondary tips at the top to extend the growth, and distribute them evenly and tie them in time. Cut off all the secondary tips below 60 cm, and leave 3-4 leaves for topping of the secondary tips above 60 cm. In a short period of time, the branches can be covered with scaffolding.

Shoots close to the main vine bear fruit first, and when the fruit ripens and falls, it is immediately pruned to 2-3 nodes, and the buds that germinate from its stem can form new fruiting branches. After the last fruits are harvested in winter, all fruiting branches are cut from the base.

5. Fertilizer and water management After the planting seedlings sprout 2-3 leaves, fertilize once every 10-15 days, and use 20-50 grams of urea for each plant; After mid-July, apply potassium dihydrogen phosphate 3-4 times, 20-50 grams each time. After the second year, fertilize 3-4 times a year, and apply basal fertilizer around late October every year in combination with deep turning and expanding holes. Top dressing 3-4 times throughout the year, before germination in March, each plant chasing kilogram of urea, 5-7 months during the fruit development of the secondary fertilizer, mainly phosphorus and potassium fertilizer, each plant with potassium dihydrogen phosphate or compound fertilizer kilograms, during the foliar spraying potassium treasure, potassium dihydrogen phosphate and so on 4-5 times, with an interval of 15 days, to improve the quality, watering immediately after each fertilization.

In terms of moisture**, it is necessary to ensure that the water is sufficient after fruit setting and during the expansion period.

6. Harvest passion fruit that ripens and falls off naturally, juice content, juice active ingredients and flavor are good, the most suitable for fresh eating and processing juice, harvesting the fruit should be timely, timely listed or cold storage, and the fruit should not be harvested if it is not hot.
