Cherry planting in Dalian 130 years. Dalian cherry fruit is fully developed, with large fruit, plump suture, thick wax layer, bright luster, sweet and sour taste, pure flavor, thick and juicy meat and high pulp hardness.

2. Shanhaiguan cherry

In May, 20001year, Shanhaiguan District was awarded the title of "Hometown of Cherry in China" by the State Forestry Administration, and it is a national-level standardized demonstration area for large cherry production. At present, there are more than 20 varieties of big cherry mainly cultivated in Shanhaiguan District, such as Hongguang, Italian Zaohong and Meizao.

3. Luding red cherry

Luding Red Cherry is a specialty of Luding County, Ganzi Prefecture, Sichuan Province, and a geographical indication of agricultural products in China. Luding has a long history of planting red cherries. According to Wang Tong's genealogy "Mingjian", Princess Wencheng tasted red cherries when she entered Tibet. She couldn't help admiring them and took away fruits such as red cherries.

Its origin is Luding County, located in the southeast of Ganzi Prefecture, Sichuan Province, on the southeast edge of the Qinghai-Tibet Plateau. Due to the long sunshine time, large temperature difference between day and night, full photosynthesis and high accumulation of effective substances, Luding red cherry has the quality characteristics of bright color, sweet and delicious taste, delicious juice and rich nutrition.

Cutting propagation technology of cherry

1. Land selection and soil preparation: The nursery for cultivating cherry seedlings should be flat, with a slope less than 5 degrees, and the soil layer is deep, loose, fertile and well drained. Cherry seedlings are prone to damping-off disease, which is serious in hardened and moist soil. It is forbidden to raise seedlings in the previous crop of cherry seedlings or continuous cropping land in cherry orchard.

Before soil preparation, 3000-4000 kg of high-quality soil miscellaneous fertilizer and 3-4 kg of ferrous sulfate are applied per mu, and the seedbed is formed by deep ploughing and harrowing. The width of the seedbed is 1.0- 1.2 m, and the length is less than 20cm .. Where the terrain is flat and it is easy to accumulate water in summer, high-ridge seedling can be used (\.

2. Cutting cuttings: green cuttings are carried out from late June to July, and the cuttings are semi-lignified new branches of that year, with a diameter of 0.3 cm, which are too thick to take root and too thin to be nutritious. After harvest, it will be cut into branches about 15 cm long, leaving only 2-3 leaves at the top, and the lower leaves will be removed and inserted at harvest.

Hardwood cutting should be carried out near the spring when the sap is flowing. Spring cuttings can be covered with soil or film. When covering with plastic film, the upper end of cuttings can be sealed with wax for 2 cm, and the buds are exposed outside the film to delay germination, while higher ground temperature is beneficial to rooting and higher survival rate.

In order to improve the emergence rate, before cutting, the lower end (about 5 cm) of cuttings can be soaked in 100 mg/L ABT rooting powder or 50- 100 mg/L indolebutyric acid solution for 4-5 hours, and then the cuttings can be taken out.

3. Seedling management: it can take root 20-30 days after transplanting, and water topdressing when the new shoots are 20 cm to promote seedling growth. Before the rainy season comes, cultivate 5 cm at the base of seedlings. In autumn, the height of seedlings can reach 80- 100 cm, and the thickness is 0.6-0.8 cm, which meets the standard of grafting seedling.
