Embodiment 1

[0028] The invention discloses a method for cultivating passion fruit seedlings resistant to stem base rot, which adopts grafting for cultivating. The steps not specifically described in the embodiments are all prior art, and will not be described in detail here.

[0029] (1) Selection and pretreatment of rootstock: the grafting time is April 20, 2015, and the rootstock is the Passiflora safflower with a stem base thickness of more than 0.3cm. Prune the rootstock and cut off all branches and leaves above 0.30m in height .

[0030] (2) The pretreatment of scion: the scion that selects for use is the twig that has terminal bud. Choose a purple passion fruit plant that grows robustly and is free from diseases and insect pests. The thickness is 0.3cm in diameter. The top branches growing in the sunny place are used as scions. Use sharp and clean branch scissors to trim them from the vines, cut off the flower buds on them, and then shorten them. Cut into long scions of about 10 c...

Embodiment 2

[0036] The invention discloses a method for cultivating passion fruit seedlings resistant to stem base rot, which adopts grafting for cultivating.

[0037] (1) Selection and pretreatment of rootstock: the grafting time was on July 2, 2015, and the passionflower safflower with a stem base thickness of more than 0.3 cm was used as the root stock. The root stock was pruned, and all branches and leaves more than 0.20 m were cut off.

[0038] (2) Pretreatment of the scion: select a yellow passion fruit branch with a thickness of 0.3 cm in diameter, which is robust and free from diseases and insect pests, as the scion, and trim it from the vine with sharp and clean branch scissors, and remove the tender leaves with a length of about 10 cm at the top. Branches, keep the remaining branches for utilization, cut off the tendrils, twigs and flower buds on it, and then short-cut them into 15cm long scions, ensure that there is at least one node at the top of each scion, and keep a quarter ...

Embodiment 3

[0045] The invention discloses a method for cultivating passion fruit seedlings resistant to stem base rot, which adopts grafting for cultivating.

[0046] (1) Selection and pretreatment of rootstock: The grafting time was on June 2, 2016, and the rootstock was safflower passionflower with a stem base thickness of more than 0.3cm. Prune the rootstock and cut off all branches and leaves above 0.35cm in height .

[0047] (2) the pretreatment of scion: select the purple fruit passion fruit plant that grows vigorously and do not have damage by disease and insect, the thickness is the branch of diameter 0.3cm as scion, and each scion is cut into 15cm long, and each scion upper end guarantees that there is a node, node. Keep a quarter of the size of the leaves at the place, and then put the scion in a ziplock bag that has been sprayed in advance to moisturize the scion.

[0048] (3) Grafting: Cut the lower end of the scion into a 3cm long positive wedge on both sides, then split th...

Abstract

The invention discloses a seedling cultivation method capable of enhancing the resistance of a passion fruit plant to the stem base rot. The seedling cultivation method is characterized in that passiflora coccinea is taken as a rootstock, a passion fruit branch is taken as a scion, a splitting method is adopted for grafting cultivation, and a passion fruit seedling resistant to the stem base rot is obtained after grafting survival. The seedling cultivation method specifically comprises the following steps: rootstock selection and pretreatment, scion pretreatment, grafting, post-grafting management, transplantation and the like. The seedling cultivation method disclosed by the invention has the benefits that the advantages of the passiflora coccinea in the resistance to the stem base rot and the excellent fruit flavor of a passion fruit are integrated, and the defects that an original passion fruit seedling is susceptible to the stem base rot and is not strong in resistance are overcome, so that diseases in the passion fruit planting process are reduced, and the requirement that the seedling is required to be replanted every 1 to 3 years is avoided; the life span of the passion fruit plant and the fruit harvest life are prolonged, and the cultivating and planting costs of the seedling are reduced; therefore, the seedling cultivation method is of great significance in promoting the large-scale planting of passion fruits and has important enlightenment for the cultivation of high-quality seedlings of other plants of passiflora.

Description

technical field [0001] The invention belongs to the technical field of passion fruit seedling cultivation, and in particular relates to a seedling cultivation method capable of significantly enhancing the resistance of passion fruit plants to stem base rot. Background technique [0002] Passion fruit is another name for passion fruit varieties with strong edible and good taste, mainly including purple passion fruit (Passiflora edulis) and yellow fruit passion fruit (P.edulis var.flavicarpa), and two varieties The series of varieties obtained by crossing each other are tropical and subtropical perennial herbaceous to semi-woody vine climbing plants, which can reach more than 10 meters in length. They are native to Australia and Brazil in South America, and are now widely distributed in tropical and subtropical regions. The planting areas are distributed in Taiwan, Guangdong, Fujian, Guangxi, Yunnan, Zhejiang, Sichuan and other provinces. Passion fruit can be eaten as fresh f...
