Passion fruit is native to South America and is usually planted in tropical and subtropical regions. Passion fruit is known as the "king of drinks" because it is rich in protein, fat, vitamins and other compounds and amino acids. There are many kinds of farmers planting passion fruit in China, but it is not a simple matter to improve the quality and yield of passion fruit. How to improve the quality of passion fruit? Take a look with me.

Timely application of base fertilizer

1. Before planting, combine with soil preparation, fully apply base fertilizer and lay a good foundation, so that passion fruit will grow vigorously, be healthy, have fewer pests and diseases, and have no problems in yield and quality. When topdressing, organic fertilizer is the main fertilizer, and medium and trace element fertilizers are added appropriately to ensure comprehensive nutrition.

2. After planting 15 days, the roots began to grow. Apply 0. 1 kg compound fertilizer or 2.5 kg human excrement every 20 days. At the same time, spraying 0.5% urea on leaves can promote the growth of passion fruit.

3. Apply 0. 1 ~ 0. 15 kg potassium fertilizer and 0. 1kg urea to promote flower bud differentiation; In the fruiting period, 5kg of decomposed human manure and 0. 15kg of potassium fertilizer were applied to each plant to promote the fruit to become bigger and better; At the late stage of fruit production, 0. 1kg compound fertilizer and 0.2kg urea were applied to each plant to promote the rapid recovery of tree vigor.

Drought and flood

1. Passion fruit has shallow roots and is distributed in 5-40cm soil layer. Its water demand is relatively "high", and it likes humidity but is afraid of drought and humidity. In water resources management, we should follow the principles of timely watering in drought, timely drainage in rainy season and taking certain water-saving measures.

2. If the soil is dry at seedling stage and flower and fruit stage, it should be watered properly to keep the soil moist and ensure the root system to grow well. Watering is usually done in the morning or evening. In rainy season or heavy rainfall, drainage ditches should be built in advance to facilitate timely drainage, avoid excessive humidity in the field and reduce bacterial infection. You can plant grass or spread straw between rows to keep the soil moisture.

3. Especially in the flower and fruit period, if the weather is dry and the soil is short of water, it will affect the development of flowering period. The fruit is not only small, but also has less pulp, and even falls early. /kloc-If it doesn't rain for more than 0/5 days, water it in time to ensure the water supply is in place.

Timely farming

1, after the rain in summer and autumn, the orchard should be planted with 5- 10 cm, supplemented by weeding, and all weeds and litter should be buried in the soil to improve the soil. Rooting culture should be carried out for 2 ~ 3 times during the fruit expansion period and after picking, so as to keep good breathing and growth.

2. In addition, passion fruit orchards are prone to grow weeds, especially after rain and before fruit picking. Weeds on the ground should be cleared manually in time, and pesticides should not be used as much as possible. You can also interplant vegetables in the orchard to increase your income, but don't be too close to the roots. After put into production, interplanting can no longer be carried out, which is not conducive to orchard management.

? Plastic trimming

1, the branches and leaves of passion fruit grow rapidly. If not pruned in time, too dense leaves will cause diseases and affect the yield. After planting, the buds should be wiped once a week to make the main vines grow stronger.

2. After harvest, fruits should be pruned as early as possible. Branches close to the trunk should be trimmed with 1-3 nodes to promote the formation of new fruiting branches. After the last harvest, all the fruit branches should be cut off from the base.

hand-pollinate

Passion fruit only has a one-day flowering period, the flower structure is "different" and the natural pollination rate is very low. Even if it can be pollinated by itself, it is uneven and easy to deform after fruit setting, which requires artificial pollination. After 30 minutes of flowering, pollinate with hand brush, and finish pollination before closing the flower.

This is how to improve the quality of passion fruit. In the process of passion fruit planting, it is necessary to prevent and control the erosion of pests and diseases in time to ensure the yield and quality of passion fruit. Passion fruit falls automatically when it matures, and growers must ensure its original quality and harvest it in time.
