How to fertilize passion fruit for high yields? A detailed guide to practical techniques
Passion fruit is a fruit that has become popular in recent years. Although passion fruit is a fruit-bearing tree, its physiological habits during cultivation are more like those of vining vegetables. It is not only a fruit tree, but also has a certain climbing ability. Therefore, in daily management, it cannot be managed according to the methods used for ordinary fruit trees. The same applies to fertilization. So how should passion fruit be fertilized? How can fertilization make passion fruit high-yielding? Let us take a look below!
1. Base fertilizer
Base fertilizer is applied when planting passion fruit or when tilling the soil during harvest. Its purpose is to increase soil fertility and strengthen the fruit tree's nutrient absorption. Generally, organic fertilizer and microbial bacterial fertilizer are used. The amount is determined by factors such as planting area and soil fertility. About 5 kg of organic fertilizer is applied per plant. Apply 50-100 kg of dolomite powder per mu. When applying these fertilizers, be careful to mix them with the soil, and then thoroughly blend the fertilizer with the soil through plowing and intertillage.
2. Seedling-stage fertilizer
Passion fruit is generally established by transplanting. After passion fruit seedlings are transplanted, water them promptly, because the seedlings have suddenly changed their growing environment and cannot adapt immediately, so the seedlings first need to adapt to the soil, and seedling-stage fertilizer should not be applied immediately. About two weeks after passion fruit is planted, the seedlings gradually adapt and the roots begin to grow. At this time, some Sea Elf biostimulant should be properly applied to promote root growth and development. After new leaves are found, apply a high-nitrogen multi-element compound fertilizer every half month to promote and strengthen the shoots.
3. Flower-promoting fertilizer
Flower-promoting fertilizer is used to promote flower quality and improve nutrient absorption. The fertilization time is generally about fifteen days before flowering, when passion fruit has successfully climbed onto the trellis. At this time, flower-promoting fertilizer can begin to be applied. Flower-promoting fertilizer can generally be based mainly on high-phosphorus and high-potassium compound fertilizer, and the target of fertilization is plants with good development and large flowers. After the flowers fade, an appropriate amount of post-flowering fertilizer can be applied, but if the flower quantity is unsatisfactory, topdressing with flower-promoting fertilizer should be stopped to prevent flower drop.
4. Fruit-strengthening fertilizer
The purpose of fruit-strengthening fertilizer is to enlarge the fruit and enhance quality. After passion fruit flowers and sets fruit, fruit-strengthening fertilizer can be applied, generally once every 2-3 weeks. It is mainly based on phosphorus and potassium fertilizers, but attention should also be paid to supplementing trace elements, such as calcium and magnesium. If high temperature and drought occur, the fertilizer should be mixed with water and sprayed together, which not only ensures the nutrients needed by passion fruit but also supplies water in time. However, the roots of passion fruit are very fragile, so when applying water and fertilizer, trenches should not be opened, to prevent the fertilizer from burning the roots. Also, to prevent fertilizer loss after application, fertilization can be done by drenching.
The above are the high-yield fertilization techniques for passion fruit compiled by the editor. Passion fruit is different from other fruits; its growing environment and growth habits are very similar to some vining vegetables. Therefore, it cannot be managed and fertilized according to ordinary fruit methods. Everyone should also pay attention to the pests and diseases of passion fruit trees. If pests and diseases are not controlled, passion fruit yields will be greatly reduced. For details, interested friends can learn more from previous articles on Qinnong.com!
