How to grow passion fruit for high yields? Detailed explanation of key cultivation techniques
There is now a very popular drink on the market, and that is one made from passion fruit, with considerable economic value. Secondly, the effects and nutritional value of passion fruit are also very considerable. Although the planted area of passion fruit has increased, the yield has not grown noticeably. Today Qinnong.com brings you a few little tricks that can make passion fruit high-yielding. Let's take a look.
1. Sow at the right time
If you want high yields of passion fruit, then the planting time must be reasonable. So when is the best time to plant passion fruit? According to research, passion fruit can be planted in two seasons, namely February and March in spring and August and September in autumn. The best planting times are from the end of February to mid-March and from the end of August to September. The main reason is that the temperature and conditions at this time are very suitable for the growth of passion fruit, so if you want high yields, be sure to remember to plant during these two periods.
2. Planting conditions
Passion fruit has a very strong ability to adapt to the environment, but if you want to increase the yield, then you still need to understand the conditions most suitable for its growth. If conditions permit, we should choose an area with developed transportation as much as possible, and it is best to plant it in sandy soil with sufficient fertility, so that its water retention and permeability are better. The planting temperature is best kept between 15 and 28 degrees, the lowest temperature cannot be lower than 8 degrees, and the highest temperature cannot be higher than 30 degrees. Therefore, in winter, a greenhouse must be used to keep it warm, while in summer, heat dissipation is needed to increase ventilation.
3. Reasonable density
In order to increase the yield, the planting density needs to be planned well when planting. According to relevant surveys, an average of 50 to 80 passion fruit trees can be planted per mu, distinguished according to different plots. For example, about 50 to 60 trees can be planted in plots with strong soil fertility, while 70 to 80 trees can be planted in relatively barren plots. Generally, the planting spacing is about 3 meters between plants and about 4 meters between rows. This planting density is relatively scientific.
4. Scientific fertilization
The growth lifespan of passion fruit is generally about 5 years, so fertilization at each stage is somewhat different. During the seedling stage, nitrogen fertilizer is generally the main type, then some manure and urine water is applied as a top dressing, with a small amount of urea added for irrigation. When it grows to a certain extent, a little potassium fertilizer can be added. For passion fruit trees in the fruiting stage, fertilization needs to be done in batches. Before flowering, urea is generally applied to promote the growth of branches and leaves; during the flowering stage, phosphorus fertilizer is applied; during the fruiting stage, potassium fertilizer is applied; and after harvesting the fruit, nitrogen fertilizer is applied. The amount used each time does not need to be too much, and fertilization can follow the principle of frequent application of thin fertilizer.
5. Pruning of branches and leaves
Passion fruit trees must be pruned at certain times, otherwise the yield will be affected. Pruning is generally divided into two seasons, namely spring and autumn. At this time, after cutting off old branches and diseased branches, new branches will grow. If pruning is done at other times, it will not, and it may even cause the passion fruit trees to age prematurely and reduce yield. The purpose of pruning is to maintain ventilation in the field. Finally, when pruning, we must prune lightly, otherwise it will cause the plants to die, and the loss will be severe.
