What if passion fruit seedlings have viruses?
1. Passion fruit should be planted in February and March every year. The economic cultivation cycle of passion fruit is generally 4-5 years. After harvesting in the fifth year, the old plants will be cut down and completely renewed. Because passion fruit is a tropical fruit, it is easy to be infected with virus after continuous cropping, which reduces the yield and quality. In order to reduce the harm of virus infection to passion fruit, it is best to update and plant virus-free healthy seedlings every year.

The planting distance of passion fruit is vine fruit tree, and the branches are extended, so the row spacing is 3 meters, the plant spacing is 3-3.5 meters, and there are about 70 plants per mu; The row spacing of single-row hedgerow cultivation is 1.7- 1.8m, and the plant spacing is 3.5-4m, about 0/00 plants per mu.

2. Planting method: dig a planting ditch with a width of 60 cm and a depth of 20-30 cm according to the predetermined planting interval, first put mixed compost or other soil miscellaneous fertilizers, and add 0.25 kg of phosphorus +0. 15-0.25 kg of compound fertilizer to each plant, and then start planting. After the plant survives, the axillary buds should be pulled out at any time, leaving only the terminal buds of the main vine.

2. During passion fruit planting, scaffolding must be erected for management and harvesting. There are many forms of scaffolding. At present, there are mainly horizontal scaffolding and single-line fence scaffolding. Single-line fence-frame column is 2.3 meters high, set between plants and planted about 30 centimeters underground. Pull two lines per column 12.
