Although passion fruit belongs to fruit trees, its biological learning is more like melons. It grows rapidly and has the ability to cling. It has both vegetative growth and reproductive growth, which is quite different from ordinary fruit trees, so there will be differences in fertilization management.

Fertilizer requirements of passion fruit

Passion fruit fertilizer is in high demand

Passion fruit grows vigorously and has a large amount of growth. It can be planted in the same year and can bear fruit in the same year, so the demand for fertilizer is relatively large.

Preference for fertilizer types

Passion fruit requires a lot of nitrogen and potassium, followed by phosphorus, calcium, and magnesium. In addition, it also needs trace elements such as boron, zinc, iron, manganese, and molybdenum.

At different periods, passion fruit has different nutrient requirements. For example, when the bud grows, the nitrogen consumption is large; the demand for phosphorus, boron, magnesium and other elements increases during the flowering period; potassium and calcium should be supplemented when the fruit is colored.

Passion fruit likes fat, but also afraid of fat

Passion fruit is a shallow-rooted plant. The top dressing is too close to the root system, excessive fertilization, too high concentration, and the application of immature organic fertilizer, etc., may cause fertilizer damage.

Passion fruit fertilization program

Passion fruit base fertilizer

Mainly organic fertilizer or microbial fertilizer, combined with calcium magnesium phosphate fertilizer or dolomite powder. The dosage depends on the fertility of the soil. Generally, 3~5kg of organic fertilizer is applied, 100~200 kg of dolomite powder per acre, which needs to be mixed with the soil evenly, or plowed into the soil through tillage or rotary tillage.

Passion fruit seedling fertilizer

After transplanting passion fruit seedlings, pay attention to watering, keep the soil moist, and let the seedlings gradually adapt to the new environment, and don't rush to fertilize them.

Generally, the roots of passion fruit will start to grow 10~15 days after planting

.

After the new leaves are grown, topdressing high-nitrogen multi-element compound fertilizer or high-nitrogen flushing fertilization is applied every 12 to 15 days to promote shoots and shoots.

Passion Fruit Flower Promoting Fertilizer

In the first half month of flowering (after putting on the trellis), apply pre-flower fertilizer, and use high-phosphorus and high-potassium compound fertilizer to improve flower quality. Apply post-flower fertilizer after the flower has withered. If the amount of flowers is small, do not apply fertilizer.

Passion fruit strong fruit fertilizer

After each flowering and fruit setting (about once every 15-20 days), use phosphorus and potassium fertilizer as the main fertilizer. Pay attention to the supplement of middle and trace elements such as calcium and magnesium. It is recommended to mix with water and spray it in drought.

Due to the shallow root system of passion fruit, it is not advisable to ditch during top dressing to avoid root damage. After application, the soil can be slightly covered to avoid fertilizer loss, or the method of leaching can be used.

Passion fruit foliar top dressing

In addition to soil fertilization, foliar fertilizer should be used in conjunction with the key periods of passion fruit to promote flowers, preserve fruit, promote swelling, and color, and take advantage of the rapid and efficient characteristics of foliar fertilizer to meet the nutrient needs of passion fruit in this period.
