Description

Technical Field

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

[0002] Fig (Ficus carica) is a popular fruit tree that is not only widely used for food and medicine, but also favored by gardening enthusiasts for its unique growth habits and ornamental value. There are many ways to propagate figs, including sowing, cuttings, division and grafting. Among them, grafting is an efficient means of propagation and is widely used because it can maintain the genetic characteristics of excellent varieties, improve plant resistance and promote fruit quality.

[0003] The core of the fig grafting breeding method is to combine the branches (scion) of excellent varieties with the vigorously growing rootstock 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 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 the success rate of grafting. 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), the scion should select healthy, mature, annual branches without pests and diseases, and the stock should have the characteristics of vigorous growth and well-developed root system. The grafting knife needs to keep sharp and be disinfected to avoid the spread of pathogens. Management after grafting is equally important, including reasonable watering, fertilizing, pest control and timely unbinding of grafting film, etc., these measures can improve the grafting survival rate to a certain extent, but there is no obvious promotion effect for fig yield. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a fig grafting cultivation method.

[0013] Furthermore, one-year-old Ficus microcarpa with a diameter of 0.5 to 0.8 cm was selected as the rootstock.

[0014] Furthermore, one-year-old semi-lignified branches that are free of pests and diseases, have full buds, and are strong are selected from fig mother trees as scions.

[0015] Furthermore, the first grafting and cultivation step includes the following process:

[0016] The scion is grafted onto the rootstock by cleft grafting or cut grafting, and after grafting, the scion seedling with the upper half cut off is retained and planted in a plug tray for lateral branch regeneration cultivation to obtain a regenerated mother plant;

[0017] The working conditions for the lateral branch regeneration cultivation include: from the 1st to the 7th day, the cultivation temperature is 25-28°C, the air humidity is 85-90%, and the light intensity is 120-140 μmol·m -2 ·s -1 The light intensity was subsequently adjusted to 280-350 μmol·m -2 ·s -1 .

[0018] Furthermore, the second grafting and cultivation steps include the following process:

[0019] When the regenerated mother plant grows a regenerated side branch with 3-5 true leaves as a new scion, the new scion is grafted onto the rootstock by cleft grafting or cut grafting, and then cultivation and management after the second grafting are carried out.

[0020] Furthermore, the cultivation and management after the second grafting includes: 1) placing the grafted seedlings in a cool, humid, well-ventilated environment, keeping the soil moist, and watering 1 to 2 times a day; 2) within one week after grafting, spraying the scion with a nutrient solution containing a potassium dihydrogen phosphate solution with a weight fraction of 0.2 to 0.5% and a urea solution with a weight percentage of 0.1 to 0.2%, once every 3 to 5 days, and spraying continuously for 1 to 3 times.
