How to cultivate bergamot seedlings?

Fingered citron is a shrub or small tree belonging to Citrus of Rutaceae. It is a tropical and subtropical plant. It likes warm and humid environment. It is planted in all parts of the Yangtze River in China. It is cultivated in courtyards or orchards in southern provinces. It is usually used as traditional Chinese medicine, or as an ornamental plant due to its peculiar fruit shape. It has extremely high cultivation value. Let's take a look at how to cultivate fingered citron seedlings together.

aerial layering

The aerial layering propagation of fingered citron is suitable for May to July. Select the branches that grow vigorously and are too high or have been firmly planted with fruits. Insect them obliquely from bottom to top under the branches, reaching deep into the pith. Put the injured branches into the felt, tighten the lower part, fill the tube with soil, tighten the upper part, and set up pillars. Water every day. When the temperature is high and the water is sufficient, it can take root in 20~30 days. If there is a bergamot fruit on the pressed branches, it must be cut off from the mother plant when the fruit ripens yellow, about 90 days.

grafting propagation

1. Contact method: in that first ten day of August to September, selecting a 4 - 5 year old plant with a stem part of 2 - 3 cm in diameter and grow healthily, cutting off branches below the branch part of the stem base, leaving only one branch, then cutting off some cortex downwards at one side of the branch part, then selecting branches generated in spring or autumn of the previous year as scions, the thickness of which is similar to that of the rootstock and the length of which is 5 - 7 cm, cutting off part of the cortex below one side of the lower part of the scion, leaning the cut surface of the rootstock on the cut surface of the scion, Make both sides close, the middle with plastic film tight, about a week later can heal.

2. Cut the abdomen and connect: cut the rootstock flat at 5~7 cm above the ground in the first and middle of March, cut it with grafting knife, select the smooth part with slight wood as oblique section, 1~1.5 cm deep. Scion to leave 2~3 buds, and the lower end cut into 1~1.5 cm long wedge, and then the rootstock cut side and scion cut skin straight, closely inserted into the rootstock cut, with plastic film bundle, generally half a month after the healing and bud growth. At this time, it is necessary to loosen the soil and weed. After 45~60 days, start to shoot, at this time must be removed from the bandage, otherwise the new shoots easy to bend.

cutting propagation

1. Cuttings: Before cuttage, 7~8-year-old strong mother trees should be selected, old healthy branches without diseases and insect pests should be cut off, leaves and tender shoots at the top should be cut off, and cuttings growing 17~20 cm should be cut off. The survival rate of cuttage is above 90%, and the seedlings are also very strong. All young branches or long branches, can not be used, because such branches are often difficult to bear fruit after planting.

2. Soil preparation: It is best to choose thick sand soil for the cuttage seedbed of bergamot so as to take seedlings in the future. After the cuttings are selected, they should be deeply ploughed and raked, and at the same time, human and animal manure water should be applied. After that, they should be made into a high ridge 1.3 meters wide, usually about 30 cm wide and 20 cm deep.

3, cuttage: spring 2~3 months and autumn 8~9 months can be cuttage, autumn cuttage best. When inserting, open a transverse ditch on the ridge, the ditch spacing is 23~27 cm, insert the cuttings into the ditch according to the plant spacing of 15~17 cm, and do not insert them. Usually, about 12000~15000 cuttings are needed per mu. After planting, cover the soil and compact it, so that a bud at the tip is exposed to the soil surface, and the dry soil should be watered.

4, management: fingered citron inserted at any time after watering irrigation and shade, rain for a long time to do a good job of drainage. When seedling height is 7~10 cm, the clustered weak seedlings are removed, and only one strong seedling is left for each plant. Weeding in time, topdressing with light human and animal manure or ammonium sulfate 3~4 times, cultivating for one year can be transplanted.
