Erection technology of passion fruit hanging curtain

Passion fruit is generally planted in a flat shed, allowing the leaves to form a greenhouse. The fruit is under the shed, but this will make the ground and fruit unable to accept sunlight, which will greatly affect the yield and quality of passion fruit. Therefore, now the cultivation of passion fruit is mainly based on hanging curtains, so how should it be operated? The following editor brings you the technology of setting up the hanging curtain of passion fruit, let's have a look!

1. Material preparation

In the construction of hanging curtains, the first thing we need to do well is to select the materials. For qualified people, the main material had better be post-based. For the steel pipe used to support, its specification should be maintained at 32 tubes, with a thickness of 3 mm and a length of about 2.7 meters. Under normal circumstances, about 80 pieces per mu can be prepared. The steel pipes used in the surrounding support are of similar specifications, but the length should be controlled at 3 meters, with 20 pieces per mu. Crossbar is the most important, to be dominated by rebar, the surrounding support should be a little thicker, and should be kept at about 200 per mu. If the conditions do not permit, you can also replace other materials.

2. Row and plant planning

Passion fruit should be planted in the direction of rising from the east and falling from the west, so that the photosynthetic capacity of passion fruit can be maximized. If it is a mountain planting, it should be adjusted flexibly. The row spacing per mu is about 2.2 million. 75 meters, and the number of plants per mu is about 400. Then when setting up the post, a pillar is erected at 3 meters, and the length of the column is maintained at about 2.7 meters. It takes about 100 to bury 50 centimeters into the soil. Then connect the two ends of the upper and lower bars to maintain about four parallel lines. The number of planting plants between the two pillars is kept at about 4, and after growing tall, it can be introduced to 4 lines to improve the utilization rate of three-dimensional space.

3. Introduce the vine to the shelf

After the preparatory work is done, the vine introduction of passion fruit will be carried out. We want to let each seedling grow with a line, let it climb vine development, to meet the living habits of passion fruit. Wait until the seedling grows to about 1.5 meters, when it reaches the line, then top it. Then leave about two stout lateral branches at the top and use them as secondary vines to develop along both sides of the line. Wait until another seedling meets the secondary vine. Finally, all the branches growing on the secondary vine are tertiary vines, which should be hung down to bear fruit. Seedlings with a top layer of more than two meters should also be pruned in the same way.

4. Proper pruning

Pruning work is very important, we are mainly in the form of double main vines. Wait until the main vine grows to the top, erase all the branches and leaves below 50 cm. And then do a good job of cutting off the head of the side branches, that is, when the top layer is connected to the lower layer and the lower layer is grounded. It is necessary to stop cutting short, strengthen fertilizer and water management, and promote the vigorous growth of branches. In order to stop cutting each batch in the future. When the last fruit on each tertiary vine has been picked, it should be cut off, its first section can be retained, and the excess should be cut off. The main purpose is to make the second batch of third-grade vines bear fruit, and to ensure that there are about three batches of third-grade vine fruiting branches every year.

The above is a brief introduction to the construction technology of passion fruit hanging curtain. That's all for today's introduction. This article is for reference only. I hope it can help you all.
