A seedling cultivation method for enhancing the resistance of passion fruit plants to stalk rot

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...

Problems solved by technology

[0005] As the common purple passion fruit and yellow passion fruit seedlings in the domestic market, in the case of field planting, due to the occurrence of stem rot, they must be replanted every one or two years. By replanting a batch of new seedlings to maintain persistent fruiting, but even after replanting new seedlings, the seedlings behaved more disease-prone than before
