Passion fruit high yield and efficient cultivation techniques
A, passion fruit planting 1. The current year's output is planted in the same year, which is appropriate for planting in the 2-3 months of each year. Generally, the economical cultivation period of passion fruit is 4-5 years. After harvesting in the 5th year, the old strains are completely removed. Since Passion fruit is a tropical fruit, it is easily infected by viruses, and the yield and quality are reduced. To reduce the damage of passion fruit caused by virus infection, it is best to use a virus-free healthy vaccine every year. 1 Planting distance Passion fruit is a vine fruit tree, and the branches and branches are prolonged. Therefore, the scaffolding type is planted with a row spacing of 3 meters, a plant spacing of 3 to 3.5 meters is appropriate, and about 70 acres are planted; single row fence cultivation spacing is 1.7 to 1.8 meters and the plant spacing is 3.5- 4 meters is appropriate, about 100 acres of planting. 2 Planting methods According to the scheduled planting spacing, dig 60 cm wide and 20-30 cm deep for planting furrow, first put in a well-mixed compost or fulvic acid organic biological fertilizer, and add 0.25 kg of phosphorus+0.15 for each plant. - 0.25 kg of compound fertilizer, and then piercing planting, after planting and survival, the axillary buds should be removed at any time, leaving only the top buds of the main vines and spreading them on the pillars to allow the plants to climb onto the scaffolds as soon as possible. 2, scaffolding must be set during the cultivation of passion fruit in order to manage, harvest. Shelvings are available in a variety of forms and are currently based on horizontal shelving and single wire fences. The single-fence rack column is 2.3 meters high and is erected between the plant and the plant. It is implanted underground for about 30 centimeters. Each column has two No. 12 lines. 3, pruning After the pruning of the passion fruit planting, in the seedling stage should be set up to support the main vines on the scaffolding, until the main vine is 1 meter high, cut off the top buds, let it grow side vines, leaving 2 side vines on each side, Divided to both sides of the growth, when the side vine grows to 2 meters, the top side of the side vines cut off to promote secondary side vine growth. In the case of horizontal scaffolding, wait until the main vine reaches the scaffold and leave the vines growing to the four sides. Passion fruit avoid heavy cuts, no need to cut every year. If over trimming, it is easy to make the main vine gradually wither, and the whole plant will die in serious cases. Generally, after each batch of fruit is harvested, each side will have 3-4 knots for short cuts to promote the growth of side vines. At the same time, it is necessary to thin the branches that grow too dense each summer, or to suspend the branches that will delay the ground, Cut off the ground about 20-30 cm to keep it well ventilated. Second, the colonization time: depending on the height of the seedlings, seedlings up to 25 cm or more can be planted, there are watering conditions of the land can be colonized as soon as possible, water shortage land is best to be the beginning of the rainy season 5 to 6 days of planting. Before the onset of the rainy season, due to the dry weather, water is poured every 10 to 15 days to keep the soil moist. Third, the planting density: Passion fruit for the vine fruit trees, dendrite extension, so scaffolding type spacing of 3 meters, spacing of 3-3.5 meters is appropriate, about 70 acres of species; single line fence spacing 1.7-1.8 meters, spacing between rows 3.5-4 meters is appropriate, and about 100 acres are planted. Fourth, field management: Seedlings seedlings about 8 cm high Dingmiao, between the thin and thin seedlings, planting a 4-5 cm plantlets. After planting, weeding and weeding were carried out 4 times a year. Fertilizers were applied once in the autumn and in spring. The combination of fulvic acid, organic and inorganic barium combined with phosphorus and potash fertilizers was the main method. Stem cane 30 cm above the length of the vine climbing. During the period between the pregnancy buds and the results, in case of dry weather, irrigation should be timely. Fifth, water and fertilizer management: passion fruit hi moist, but avoid water scared afraid of drought, water should be drained in time, when the drought should be ground irrigation, especially fruiting period, the need for large amounts of water, to fill enough water. Scientific fertilization, newly planted passion fruit, mainly in the early stage with nitrogen fertilizer, mixed with the source of life fulvic acid leaching, every plant once every two months, the amount of fertilizer increases with the growth of seedlings, and with the fertilizer spray Shi. To promote early-onset rapid growth, the root-strengthening agent or fulvic acid nutrient solution is applied twice a day after 7 days of seeding. The interval time is 7 days. After entering the perinatal period, phosphorus and potassium fertilizer should be applied to promote flower bud differentiation. Surface spraying of potassium dihydrogen phosphate, 0.5 kg per plant applied organic inorganic wolfberry Hefei plus 0.1 kg of Goldman Sachs Potassium. After the fruit is harvested, the winter fertilizer is applied, and the fulvic acid bio-fertilizer is the main fertilizer. Each cultivating fulvic acid bio-fertilizer 1.5 kg, calcium magnesium phosphate 0.5 kg. Within 15 days after flowering, the rapid expansion of the fruit period, fertilizer and water management should be strengthened, in particular, the application of potassium fertilizer (Gaosheng potassium pot) to promote the rapid expansion of the fruit; each year alternately on both sides of the tree.
