Bergamot is also known as bergamot orange, bergamot orange, bergamot and so on. The fruit, stamens, leaves, stems and roots of bergamot can be used as medicine, which is commonly used in traditional Chinese medicine, and has the effects of resolving phlegm and stopping vomiting, promoting qi and regulating qi, strengthening spleen and relieving depression. At the same time, the fruit of bergamot can be processed into candied fruit and extracted spices, such as smoking cessation candy, bergamot, bergamot hangover tea and so on. However, fingered citron is an asexual plant, which cannot be planted by sexual reproduction under natural conditions, so it is necessary to choose its planting techniques reasonably.

First, the cutting planting technology of bergamot branches is very easy to take root. Cutting technique has the characteristics of fast growth and high survival rate. The main process of planting bergamot by cutting planting technology is as follows:

1. Establish seedbed. The quality of bergamot has a great relationship with healthy seedlings. Seedbed is a hotbed for fingered citron planting, and its construction site should be characterized by easy management, non-toxic pollution, good drainage and irrigation, sufficient water, leeward facing the sun, loose soil, favorable transplanting and sufficient illumination. At the same time, the seedbed area should be determined according to the branches of bergamot, with more branches being larger and less branches being smaller. After determining the construction site and area of the seedbed, it is necessary to deepen the land, break the clods and remove weeds. In the meantime, the finer the soil, the better. Then you can spread 2cm thick yellow sand or red sand on it. Black film can also be used instead of yellow sand and red sand to avoid excessive weeds. The best cutting spacing is 5- 10cm.

2. Title selection. In the process of selecting heading, we should pay attention to selecting mature branches, robust branches and healthy branches, such as mature branches that are robust for one year, rather than diseased branches, weak branches, tender branches and residual branches. Each branch should be 7- 10cm. Cut it too clearly, leaving no incision, leaving 2-3 leaves on the branches.

3. Cutting time. Cutting planting technology is mainly used in spring and summer, from March to April in spring and from late July to early August in summer. Choose branches without plant diseases and insect pests as strings, and string them with three bud eyes, so that the fingered citron will germinate on 15-20.

2. Grafting planting technology Compared with cutting planting technology, fingered citron planted by grafting planting technology has a longer life span, more vigorous growth and developed roots, but it requires a higher technical level, and the planting process is more complicated and time-consuming, which is not as simple as cutting planting technology. The grafting time of bergamot is generally in April, May and August. In the process of scion, we should choose the mother tree with no pests and diseases and strong tree potential, and at the same time, we should also require full bud eyes. After the scion is cut, the needles and leaves should be cut off immediately, leaving a petiole of about 3mm, and then every 50 branches or 100 branches should be tied into small bundles and stacked in rows. The main working procedures of grafting planting technology are as follows:

1. Cut the buds. On the scion, you can choose the full axillary buds of prismatic spring shoots. When cutting buds, use the middle finger and thumb of the left hand to buckle the scion upside down, and the wider side is close to the fingertips. Starting from the first bud at the base of the branch, obliquely cut a knife from the position below the bud10 mm. Then cut a knife flat on the bud base and cut through the cortex to avoid hurting the xylem.

2. Rhizome incision. According to the thickness of the rootstock, select a relatively flat position at the position where the trunk of the rootstock is 8- 15cm from the ground, and cut vertically from top to bottom, with a length of about 3cm, until it cuts through the cortex, and the section is required to be straight.

3. Embedding buds. Pinch both ends of the grafted bud with index finger and thumb, and insert the grafted bud into the incision of the rootstock, and the lower end of the grafted bud should be closely attached to the bottom of the incision of the rootstock. The cutting surface of the rhizome and the cutting surface of the bud should be closely aligned.

4. Tie the membrane. Cut the graft membrane into 25- 30cm long and 3cm wide, and wrap it from bottom to top at the joint. Pay attention to the tightness. After the whole joint is wrapped, there should be no water seepage at the joint, and the grafted buds should not be exposed. Finally, tie a slipknot. After using grafting planting technology for half a month, it is necessary to check the survival rate of bergamot. If you touch the petiole of the bud, it will fall, and the bud is bright green, indicating that it has survived. If it is yellow, the grafting is unsuccessful.
