Cultivation and management techniques of passion fruit

Passion fruit scientific name egg fruit, is a herbaceous vine fruit, generally grows in the valley from the forest, can only be planted in the tropics, the plant is perennial, long life, in addition to food, but also has a certain medicinal value, seeds can extract oil. The economic value is higher, the planting benefit is better, so there are many areas to choose planting. Planting to high-yield cultivation techniques and cultivation management after planting is very important, which is also the main content of the article.

I. cultivation techniques

1. Select a place

Passion fruit needs to grow at a higher temperature, so it is necessary to choose land for planting at low elevations; then the planting land should be flat, wide, easy to manage and transport; the root system is general, so choose deep, loose, breathable and draining soil, like fertilizer, so you should have fertile planting land.

two。 Planting

It can be planted all year round in the tropics and in spring and autumn in the subtropics. Planting needs to build a frame, generally 3 meters long and 3 meters wide, it is appropriate to plant 10 plants under such a small frame, not too much, vine crowding affects photosynthesis and growth. Before planting, each planting pit should be fully applied base fertilizer, farm manure, plant distance of about 30 cm, irrigated, covered with straw moisturizing and heat preservation.

II. Management

1. Fertilizer and water

Before fruiting, young trees should be topdressing nitrogen fertilizer once a month to keep the plant growing well, sprouting and branching, leaving branches, and preparing fruiting branches. Adult trees apply basal fertilizer in early spring, dig a circular ditch 30 cm away from the root to fertilize, fertilize a plant of about 2 to 5 jin of farm manure, and watering after covering the soil is beneficial to absorption. In the result period, topdressing should be done once, compound fertilizer should be used and absorbed quickly with water, and fertilizer should be replenished after harvest, mainly stable manure, equal mild fertilizer, heat preservation and root preservation. After the second result, there is another topdressing. The root system is afraid of drought and waterlogging. in addition to normal watering, attention must be paid to drainage after rain. flooding is easy to rot roots and even die; but lack of water will also lead to water loss, slow growth, small flowering and fruit drop.

two。 Pruning

Before sprouting, it is necessary to re-cut, generally cut off all the dead branches and diseased branches, and then leave the side branches after 60 centimeters of the main stem, and all the winding branches are reduced. Light pruning can be cut all the year round, remove excess shoots and weak branches during the growing period, and cut off most of the new shoots after picking fruit, leaving a few strong and well-jointed branches. Pruning fruiting branches, disease and insect branches, dense branches.

3. Pest control

The main diseases such as quenching disease can be treated with 800-fold liquid or Miaomiaoling liquid, and mosaic disease can be treated with 1000-1500-fold solution of lobular Huangji or 1500-2000-fold solution of viretin. The main pest is Liriomyza sinensis, which uses 1000 times of 40% dimethoate EC or 1000-1500 times of 40% diazinon EC; thrips can use 1000 times of 25% imidacloprid or 3000-5000 times of thiazine water dispersible granules.

The above is the planting and cultivation management technology of passion fruit. I hope it can bring some help to you after reading. Specifically, you can learn from experienced growers or accumulate their own practical experience, so that you can have a comprehensive understanding of the content of planting and cultivation management.
