When will the passion fruit, the king of vitamins, be fertilized? What kind of fertilizer? How often do you do it? What is mature listing? (with planting skills)

Passion fruit, also known as egg fruit, foreign pomegranate, rattan pomegranate, is a common fruit in Yunnan, Fujian, Hainan, Guangdong and other places in China. It is known as the king of vitamins because it is rich in vitamins, so many people like to eat it. When will passion fruit be fertilized? What kind of fertilizer? How often do you do it? What is mature listing?

Fertilization time:

1. Nitrogen fertilizer is the main fertilizer in the early stage, mixed peanut bran water is applied, each plant is drenched with 0.2% urea and 15% peanut bran water or human fecal urine 15 kg, each plant twice a month, the amount of fertilizer increases with the growth of seedlings, and combined with foliar fertilizer spraying.

2. Phosphate fertilizer is used during flowering, but not too much nitrogen fertilizer. Passion fruit is very sensitive to nitrogen fertilizer. Excessive nitrogen fertilizer often causes the phenomenon of "falling flowers", that is, it falls off before the bud is a little larger, and naturally there will be no fruit to harvest. Generally speaking, do not apply too much nitrogen fertilizer after the initial stage.

3. The juice of passion fruit is all in the false skin of the seed. Therefore, if the seed is underdeveloped, the content of fruit juice is naturally less. In order to ensure that the juice content can reach a certain level, there is no shortage of phosphate fertilizer to promote seed development. Using drip irrigation liquid fertilizer, it is the best way to supply phosphate fertilizer from time to time in irrigation. Of course, the use of leaf fertilizer to reduce soil interference is also one of the effective ways to supplement phosphate fertilizer.

4. Although potash fertilizer has little effect on yield, it has a great influence on whether the plant of passion fruit is strong or not. Therefore, the application of potash fertilizer should be strengthened within 15 days after flowering. Because this period is the rapid growth period of fruit, to ensure the right amount of potash fertilizer, can ensure the growth of fruit.

How often do you apply fertilizer?

Passion fruit in the seedling stage can apply more nitrogen fertilizer to promote the growth of branches and leaves, generally fertilized 1-2 times a month, in the flowering stage, the corresponding reduction of nitrogen fertilizer, the corresponding increase in the amount of phosphorus and potassium fertilizer. In peacetime, we can not only apply a single fertilizer, we should pay attention to the rational use of nitrogen, phosphorus and potassium fertilizer.

In addition, due to the different topography, soil, climate and other factors, the soil fertility is also very different. Therefore, during the planting period, the actual growth of passion fruit should be used to judge whether the nutrient elements need to be adjusted and what fertilizer should be applied. In order to do a good job in the fertilization management of passion fruit, it is not possible to rely on one step alone, which does not require the cooperation of many aspects to achieve results, so that passion fruit can grow healthily and achieve the goal of high yield.

Mature time to market:

Passion fruit belongs to autumn fruit. The flowering period is from May to July and the fruiting period is from July to September.

The best season for eating passion fruit

Passion fruit because of its pulp can exude banana, pineapple, strawberry, litchi, lemon, mango, sour plum and other fruits and other rich aroma. In foreign countries, passion fruit also has "king of fruit juice", "cash cow" and other laudatory names. Passion fruit can be eaten raw or used as vegetable or feed. The medicine has the effect of excitement and strength. The pulp is juicy and can be made into fragrant and delicious drinks by adding calcium bicarbonate and sugar.

Passion fruit ripens after the end of July and tastes best from August to October.

Planting techniques:

1. Scientific selection of species

Passion fruit is mainly divided into yellow fruit and purple fruit, the sweetness and taste of purple fruit are higher than yellow fruit, and the yield is higher in the same environment. Purple fruit plant disease resistance is poor, later fruit tree management needs to spend more time and energy; yellow fruit disease resistance is strong, and the fruit is golden, beautiful appearance, but yellow fruit natural pollination ability is poor, fruit setting rate is relatively low. At the present stage, purple fruit cultivation is the main planting in Guangxi. When carrying out large-scale cultivation, passion fruit varieties can be reasonably selected according to market demand and actual situation, so as to maximize profits.

2. Reasonable selection of land

Passion fruit has strict requirements on the cultivation environment, like to be moist, avoid stagnant water and fear drought. When selecting a site, the following factors should be taken into account: first, the cultivated land should have good ventilation, and the land which is sunny and leeward is suitable; second, the land which is rich in organic matter and the soil layer is deep and loose, with a soil pH value of 5.5 to 7.0, making it convenient for drainage and irrigation; third, the site should be far away from the paper mill or chemical plant to prevent the fruit from being polluted and affect the quality. After the completion of the site selection, the plot arrangement should be carried out, and the impurities in the soil can be cleaned up deeply to improve the soil permeability and create good conditions for the normal growth of passion fruit.

3. Scaffold construction

Passion fruit belongs to lianas, and a certain number of supports should be built in the process of cultivation to facilitate the climbing and growth of vines. The height of the support is controlled at 1.5 ~ 2.0m, and the depth of the support is about 20cm. Can use hedge frame, scaffolding, bamboo pole support and so on. Scaffolding materials can be made locally, and bamboo poles can be used to build scaffolding. It is suitable to dig holes according to the row spacing of (2 × 3) m × (3 × 4) m, and it is suitable to plant 70 plants per 667m2.

4. Planting and pruning

Planting needs to be determined according to seedling height and local temperature. When the seedling height is above 20cm and the daily average temperature is above 15 ℃, it can be planted. It is appropriate to plant in the evening or cloudy day, spread the root system of the seedling and straighten out the root system, and mix the appropriate amount of mature organic fertilizer with sandy loam soil to make colonization soil or cover soil. After planting, pour root water and cover with film or straw. If the weather is dry and there is no rain after planting, it is necessary to determine the amount and frequency of watering according to the wetness of the soil. It is usually watered once a week to keep the soil moist. And according to the growth of passion fruit branches, pruning properly to avoid twining each other.

5. Field management

After the growth of the planted seedlings is restored, the lateral buds should be erased in time to promote the thickening of the main vine. When the main vine grows to the height of 50~80cm, it should be guided on the shelf. Timely drainage when waterlogging occurs in rainy days, and irrigation should be carried out in time to ensure the normal growth of passion fruit. Passion fruit is mainly nitrogen fertilizer in the early growth stage. Before putting on the shelf, each plant was sprayed with water with 50g Eurasian-American water-soluble fertilizer, two or three times a month, and the amount of fertilizer increased with the growth of seedlings, combined with foliar fertilizer. After entering the production period, increase the application of phosphorus and potassium fertilizer to promote flower bud differentiation. The fruit expands rapidly within 15 days after flowering. The management of fertilizer and water should be strengthened and the application of potash fertilizer should be increased to promote the rapid expansion of fruit. Each plant was drenched with 100 g Eurasian fertilizer and drenched every 7 days. Winter fertilizer was applied after fruit harvest, and farm manure 20kg and calcium magnesium phosphate fertilizer 0.5kg were applied to each plant.

(6) Disease and pest control

The common diseases in passion fruit cultivation are blight, mosaic virus and stem rot. In view of this kind of disease, on the one hand, we should strengthen the field management, such as turning the soil and drying the soil during the cultivation interval, which can not only improve the air permeability of the soil, but also effectively kill the diseases, insects and bacteria in the soil; on the other hand, we can choose 1000 times of Kangkuling solution for spray control, which can be effective for two or three times in a row. The main pests are leaf miner, small fruit fly and so on. This kind of pest can occur in all periods of passion fruit cultivation, and can be controlled by 1000 times of trichlorfon in flowering or fruit growth period, and biological control should be used in fruit ripening period. or use a new type of pesticide with low toxicity and high efficiency. The use of pesticides is prohibited 30 days before fruit picking to ensure product safety.

.7 timely picking

Passion fruit takes 70 days from flowering to picking. The best time for picking is 10 days before falling fruit, and it is best when the fruit begins to change color and emit fragrance. When picking, some of the ripe fruit will fall by itself, and the fallen fruit can also be collected at this time. If the fruit has rotted, then the fruit cannot be sold as a commodity fruit.
