Bergamot is a small evergreen tree or shrub of Citrus in Rutaceae. The flowering period is April-May, and the fruit is mature10-65438+February. Bergamot is a good fruit in potted plants.
I. Temperature
Bergamot likes warm, humid and sunny environment and is afraid of cold. The temperature of breeding environment shall not be lower than 3℃. Afraid of dryness, it is suitable for cultivation in fertile acidic sandy soil.
Second, pruning
Papaya should keep 3-5 fruiting branches to promote the formation of crown, and subtract 2/5 from long branches in summer to produce fruiting branches.
New buds germinated in autumn should be properly preserved for the next year's fruit. Anything that is not easy to bear fruit should be removed. There are too many bergamot fruits, so it is necessary to remove the diseased and weak fruits in time and supplement the nutrition for the good quality fruits.
Third, cutting
Although cutting propagation is simple and fast, with high survival rate, it has poor drought and cold tolerance, underdeveloped root system and short life span.
However, the propagation of bergamot is mainly cuttage, which is usually carried out in April-May in spring. One-year-old robust branches were selected as cuttings, which were about 20 cm long and planted in sandy soil.
After cutting, it can take root in 2 months by supplementing the moisture of cutting soil, and the cutting seedlings can be transplanted into flowerpots when the height of the plants is 30 cm in about 9 months.
Fourthly, the basin soil.
Potted soil is a slightly acidic culture soil made of garden soil, compost and river sand, which requires that the culture soil must be loose and fertile and rich in organic matter. Choose a potted plant with plain mud, and the diameter of the flowerpot is slightly smaller than the crown.
Cover the drainage hole with tiles first, add 3 cm thick coarse culture soil or coarse sand, and then plant. When planting, cut off the main root, the long lateral root and the injured root, then add the culture soil and compact it.
After planting, water the roots and plant them in the shade.
Verb (abbreviation for verb) water
Topdressing pancake fertilizer every 10 days or so in the growing season, and topdressing is not required after 10 months. Always pay attention to watering, don't let the soil dry, and the pot soil can be slightly dry in winter. Turn over the basin in time during the rainy season, and don't let water accumulate in the basin.
When the new shoots grow to 15-20 cm in spring, they should be picked in time to enrich the branches, which is beneficial to flower bud differentiation and fruiting branches.
In winter, it is necessary to go indoors for winter, and the indoor temperature should be kept above 3℃ and the humidity should be kept at 70-80%.
Six, pest control
Bergamot is very delicate and prone to anthracnose, bituminous coal disease, scale insects and other diseases and insect pests. When pests and diseases are found, they should be prevented in time. We pay attention to strengthening management and keeping trees clean and hygienic. Regular spraying of Bordeaux mixture can effectively control pests and diseases.
