How to choose passion fruit seeds? What are the methods of raising seedlings?

Passion fruit is currently a very popular fruit, rich in vitamins, high medicinal value, sweet and sour delicious, known as the "king of fruit juice". At present, the economic value of passion fruit in the market is also considerable, and demand falls short of supply, and there are many farmers planting. So how to choose passion fruit seeds? What are the methods of raising seedlings? Next, let's have a look with the editor.

First, how to select passion fruit seeds?

First of all, we must choose large and healthy passion fruit, must be ripe, if you think the passion fruit is not too ripe, you can put it for a few days and then take the seeds, so that the success rate of seed sowing will be higher, we will wash the passion fruit seeds taken out, and then dry them in a cool place and keep them in reserve.

Second, what are the seedling methods of passion fruit?

1. Seed breeding of passion fruit

The seeds of passion fruit have no dormancy period and can be sown after harvest. Seed propagation can be carried out all the year round, but it is better to sow in spring and autumn. The plant with strong growth, no diseases and insect pests, high and stable yield was selected as the mother plant, the fruit with correct shape, heavier and fully ripe fruit was collected, the seeds were taken out, the aril was removed, washed and dried and sown as soon as possible. The method of soaking and fermenting in water for 3-4 days or shaking it in a bottle with coarse sand and rubbing the seed coat with sandpaper can improve the germination speed of seeds.

When sowing, sow 1.5 kg seeds per mu with 15g of domaolin for about 20 minutes, take river sand as the substrate, and then spread the seeds evenly on the seedbed, cover with a thin layer of grass and drench with enough water. Passion fruit seeds generally take about 20 days to break their shell and bud, and the optimum temperature for germination is 24C. When the temperature is below 15 ℃, it should be covered with plastic film to keep the soil moist during the whole seedling stage. After sowing, water should be drenched according to the weather conditions, and water should be sprayed once every morning and evening on a sunny day, and it will be unearthed about half a month later.

When the seedling emergence reaches more than 80%, it should be fertilized in time, and can be poured with dilute dung water or less than 0.3% dilute urea solution to cultivate strong seedlings. After the seedlings grow 2 true leaves, they are sprayed with 0.1% carbendazim or topiramate solution every other week, twice in a row. In order to improve the survival rate of planting and facilitate transportation, bagging cultivation can be carried out when the seedlings grow 1 or 2 true leaves, and 4 (clean land seedlings) ~ 8 (bagged seedlings) can be planted in the nursery and transplanted to the field.

2. Cutting seedling of passion fruit.

Most of the purple fruit varieties commonly planted are hybrids with great variability in seed reproduction, so cutting seedlings and other vegetative propagation methods should be used in large area production. The branches selected for cutting seedlings of passion fruit should contain high carbohydrates and appropriate amount of nitrogen nutrition, which has a good effect on rooting. Therefore, it is better to use sunny, robust and mature 2012 branches as cutting materials.

The passion fruit cuttings are cut into 2-3 nodes, the lower cut is obliquely cut parallel to the bud, the distance between the incision and the internodes is 1 cm, the upper cut is about 3 cm apart from the node, it is best to have a whole leaf, and 0.5 cm bud is better in the leaf axil. The selection of such cutting materials is not only beneficial to early rooting, but also the sprouting and growth of new shoots are faster after rooting, which is more effective than the cuttings without leaves or half leaves.

After cutting the cutting material, it is best to soak the cutting material with Abr rooting powder 25 mg / kg water for 30 minutes, and then cuttage, cutting depth up to the cutting length of 2 cm 3. Under normal circumstances, passion fruit cuttings take root 20-30 days after cutting, and the seedling rate can reach more than 80%. It can then be implanted into the plastic bag soil, and after the growth is restored, it can be planted in the field, or even directly cultivated in the plastic bag (cup) soil.

The above is the introduction of passion fruit. When passion fruit is planted, farmers must choose the main varieties according to the characteristics of passion fruit varieties and local climatic conditions.
