A Detailed Explanation of the Latest Key Points on Fertilizing Passion Fruit
At first, passion fruit was a wild fruit, but as its nutritional value was gradually developed, it became deeply loved by women in the market, and market demand increased sharply, so the scale of cultivated passion fruit gradually expanded. So do you know how passion fruit should be fertilized? Now follow the editor to learn about it in detail.
1. Base fertilizer
Before planting passion fruit, we need to apply enough base fertilizer. The base fertilizer is mainly organic fertilizer, and of course microbial bacterial fertilizer or farmyard manure can also be used. Secondly, in order to improve the soil structure, we will also appropriately use some trace element fertilizer or dolomite powder. The amount of base fertilizer per mu should be controlled at about three thousand to four thousand jin. Mix the base fertilizer thoroughly with the soil and turn it into the soil to avoid nutrient volatilization and loss of fertilizer efficiency.
2. Seedling fertilizer
Seedling fertilizer is generally applied after the passion fruit has survived planting. Do not apply seedling fertilizer too early, otherwise it will affect the survival rate of passion fruit seedlings. At least about half a month after planting should pass before topdressing. For seedling fertilizer, we can irrigate with manure and urine water, or irrigate with urea diluted in water. Of course, we can also spray a special growth-promoting fertilizer designed for fruit cultivation. For example, the effect of Sea Elf biostimulant is very good.
⟦NL>3. Flower fertilizer
Flower fertilizer refers to pre-flowering fertilizer and post-flowering fertilizer, meaning fertilization before and after flowering, used to promote flowering, prolong the flowering period, and ensure flower quality. Generally, topdressing is carried out about half a month before flowering and after passion fruit flowers fall. It is mainly phosphorus and potassium fertilizer. We usually use a ternary compound fertilizer containing nitrogen, phosphorus, and potassium for furrow topdressing.
4. Fruit fertilizer
Fruit fertilizer is actually fruit-preserving fertilizer and fruit-strengthening fertilizer, and it needs to be carried out in two steps. The first step is after the passion fruit has set fruit, spray the fruit with an agent that can preserve the fruit, and then apply potassium fertilizer in a timely manner. When the fruit grows to the size of a thumb, we need to topdress again, mainly to promote the enlargement of the fruit. It is mainly phosphorus and potassium fertilizer, combined with trace elements and foliar fertilizer for topdressing. At this time, we usually use drenching for topdressing. Other topdressing methods are not very suitable.
5. Supplementary fertilizer
Supplementary fertilization is generally during the fruit growth process or during the fruit harvesting process. If passion fruit lacks a certain element, then we need to supplement fertilization in time to avoid affecting the yield and quality of passion fruit. Among these, the most important are elements such as calcium and magnesium. Of course, when the fruit is coloring, in order to make its coloring uniform, we also need to appropriately supplement the use of foliar fertilizer.
6. Post-fruit fertilizer
Post-fruit fertilizer means that after the passion fruit is harvested, nutrients should be supplemented to the passion fruit vines in time. At this time, nitrogen fertilizer is generally the main type, and the fertilization amount should be controlled at about three thousand jin. This is also equivalent to the base fertilizer for the second year. Secondly, during the dormant period of passion fruit, we also need to topdress appropriately. During this period, farmyard manure is mainly used, and the amount per mu should be controlled at about two thousand jin.
