Description

Technical Field

[0001] The invention relates to the technical field of fig planting, in particular to a fig grafting and cultivation method. Background Art

[0002] The fig (Ficus carica) is a popular fruit tree, not only widely used for its food and medicinal properties but also highly favored by gardening enthusiasts for its unique growth habits and ornamental value. Figs can be propagated through a variety of methods, including sowing, cuttings, division, and grafting. Grafting, as a highly effective propagation method, is widely used because it maintains the genetic characteristics of superior varieties, improves plant resistance, and enhances fruit quality.

[0003] The core of the fig grafting cultivation method is to combine the branches (scion) of excellent varieties with vigorously growing rootstocks through specific technical means to form a new fig tree. In this process, the selection and implementation of grafting technology are crucial. Commonly used grafting methods include cut grafting, bud grafting, cleft grafting, and belly grafting, each of which has its own unique application scenarios and advantages. For example, the cut grafting method is suitable for situations where the rootstock and scion are of similar thickness, while the bud grafting method is more suitable for situations where the scion is thinner and the rootstock is thicker.

[0004] In the grafting process, the selection of scion, the processing of stock, the use of grafting knife and the management after grafting are all key factors affecting grafting success rate. As pointed out in the disclosed fig grafting cultivation method such as prior art (CN101743876A-exotic fig grafting cultivation method, CN107173078A-a kind of fig grafting cultivation method), scion should be selected healthy, mature, annual branch without pests and diseases, and stock should have the characteristics of vigorous growth and well-developed root system. Grafting knife need keep sharp and pass through disinfection treatment, to avoid pathogenic bacteria propagation. Management after grafting is equally important, including the timely unbinding of reasonable watering, fertilizing, pest control and grafting film, etc., these measures can improve grafting survival rate to a certain extent, but there is no obvious promoting effect for fig yield.
