Passion fruit top-grafting breeding and planting method

Abstract

The invention discloses a passion fruit top-grafting breeding and planting method, and belongs to the field of passion fruit grafting planting. The passion fruit top-grafting breeding and planting method includes the steps of (1), selecting of seeds of root stocks; (2), seedling growth and culture of root stocks; (3), processing of root stocks; (4), selecting and grafting of scions; (5), sterilization after grafting; (6), planting management after grafting; (7) prevention and control of pests. As top grafting, which is much different from low grafting in the prior art, is combined with fruit bearing hanging strings, stem rot can be controlled effectively, incidence rate of stem rot can be decreased, while output of grafted passion fruit can be increased.

Description

technical field [0001] The invention belongs to the field of grafting and planting of passion fruit, and in particular relates to a high-level grafting and planting method of passion fruit. Background technique [0002] At present, an important factor restricting the production of passion fruit is the widespread prevalence of passion fruit stem rot. [0003] Passion fruit stem base rot mainly affects the base of the plant stem 5 to 10 cm from the ground, and both seedlings and adults can be affected. The seedlings are susceptible, the plants wilt, the leaves will fall off and fade, and then the whole seedling will die; the adult plants are susceptible, and in the early stage of the disease, dark brown lesions will appear at the base of the stem of the plant, and then the cortex of the diseased part will turn. Soft, cracked and rotten, the epidermis is easy to detach, and when the humidity is relatively high, pink mold will appear on the surface of the diseased skin. The le...

Problems solved by technology

[0004] However, the traditional passion fruit rootstock grafting technology is to carry out low-level grafting when the rootstock grows to 15-20cm. There are problems in low-level grafting: grafted seedlings are susceptible to stem rot, and stem rot affects growth and affects yield and yield.

Low-level grafting is easy to infect underground germs, and the process of pollination is also easy to infect low-level and easy-to-underground germs, resulting in stem rot

[0005] The peak period of passion fruit stem rot is the high temperature and high humidity season from May to July. The general incidence rate is 20-30%, and the serious plot reaches more than 50%. It is highly contagious and spreads rapidly in the orchard. , resulting in a serious lack of plants in the orchard and a decrease in yield per unit area

Passion fruit plantations with high humidity, poor soil permeability, poor drainage, acidification, and poor light transmission are severely affected
