What kind of fertilizer should be applied when passion fruit bears more fruits?

Passion fruit, also known as egg fruit, is a vine of the genus Passiflora in the family Passifloraceae. There are many farmers who grow passion fruit. In order to produce more passion fruit, it is necessary to pay attention to fertilization to achieve the goal of high yield. So what kind of fertilizer should be applied when passion fruit bears more fruits? Let’s take a look with the editor below.

1. What kind of fertilizer should be applied when passion fruit bears more fruits?

1. Base fertilizer: Passion fruit base fertilizer usually uses organic fertilizer and microbial fertilizer, combined with calcium magnesium phosphate fertilizer or dolomite powder. Apply 3-5kg of organic fertilizer per plant and 100-200kg of dolomite powder per mu. Mix well with the soil and then apply.

2. Fertilizer in the seedling stage: After the passion fruit seedlings are transplanted, when the roots begin to grow, you can apply 300 times the liquid of Sea Elf Biostimulant Root Application to promote root growth. After new leaves grow, apply high-nitrogen multi-element compound fertilizer or high-nitrogen flush fertilizer every 12-15 days to promote shoot growth.

3. Flower-promoting fertilizer: Apply pre-flowering fertilizer half a month before flowering, mainly phosphorus and potassium fertilizers, and apply boron, magnesium, zinc and other trace elements on the leaves. Spray boron fertilizer on the leaves during the bud stage and after flowering to increase the fruit setting rate.

4. Fruit-enhancing fertilizer: Apply fertilizer about 15-20 days after each flowering and fruiting, mainly using phosphorus and potassium fertilizers. Pay attention to the supplementation of trace elements such as calcium and magnesium. It is recommended to dilute with water and then apply during drought.

5. Foliar topdressing: During the key periods of passion fruit such as flowering, fruit preservation, swelling and coloring, foliar fertilizers such as boron source library, cytokinin, and sea elf biostimulant foliar type can be used to quickly and efficiently meet the nutrient needs of passion fruit.

6. Fruit ripening period: mainly foliar topdressing. You can spray Hongku foliar fertilizer, which contains organic potassium, soluble phosphorus, chelated trace elements, Haematococcus pluvialis extract, etc. It is very helpful for color change, acid reduction and sweetness increase, and juice production.

7. High-potassium fertilizer: During the fruit expansion period, the use of potassium fertilizer should be increased to promote rapid expansion of the fruit.

1. Fertilization principles

The fertilization principle of passion fruit should be based on a nitrogen, phosphorus and potassium ratio of 2-1-4, that is, the demand for potassium fertilizer is the highest, followed by nitrogen fertilizer, and the demand for phosphorus fertilizer is relatively low. At the same time, avoid excessive application of nitrogen fertilizer to prevent problems such as plant growth and deterioration of fruit quality.

2. Fertilization time

The growing season for passion fruit is from spring to autumn, and regular fertilization is required during this period. In winter, due to the slow growth of plants, the frequency of fertilization can be appropriately reduced. In addition, within 15 days after flowering, the fruit rapidly expands, and fertilizer and water management should be strengthened, especially increasing the application of potassium fertilizer.

3. Fertilization method

When applying fertilizer, be careful to spread the fertilizer evenly around the plants to avoid direct contact between the fertilizer and the stems and leaves of the plants to avoid burning the plants. At the same time, try to avoid direct contact between fertilizer and roots to avoid root diseases. Water the plants in time after fertilizing to facilitate the absorption of fertilizer.

The above is an introduction to what fertilizers should be applied when passion fruit bears fruit. After passion fruit bears fruit, phosphorus and potassium fertilizers should be applied in combination with medium and trace element fertilizers. At the same time, necessary nutrients should be supplemented through foliar topdressing to improve fruit quality and yield.
