Cherry cherry main place of origin: the world's cherry is mainly distributed in the United States, Canada, Chile, Australia, Europe and other places; China's main places of origin are Shandong, Anhui, Jiangsu, Zhejiang, Henan, Gansu, Shaanxi, Sichuan and so on.
Chinese cherries are weak in cold resistance, preferring warm and moist climate, suitable for cultivation in the place where the average annual temperature is 15~16℃. Sweet Chelsea prefer cool and dry. Chelsea natural dormancy period of about 80 to 100 days. Sweet Chelsea to complete the dormancy of the cold requirement of 7.3 ℃ below 1100 ~ 1300 hours, sour Chelsea need 1200 ~ 2500 hours.
Chinese cherries have a short dormancy period, in late winter and early spring when the temperature warms up easy to sprout, if the "spring cold" (frost or snow), so that the flower organs frozen, will seriously affect the yield, or even grain harvest.
So the development must pay attention to the local spring cold wave each year whether the time of low temperature and cold wave attack and the flowering period coincide, in consecutive years in the flowering period of Chelsea unfavorable weather (frost, snow, wind), etc. can not be planted in the place. Even in places where catastrophic weather rarely occurs, it is important to choose suitable terrain for planting when establishing a garden.
Expanded Information:
The vertical distribution of Chinese carrion roots is generally concentrated in the soil layer about 20 centimeters deep, which requires loose soil and good drainage and irrigation conditions. Heavy clay soil is not suitable for planting Chelsea. Because of the intolerance of Chelsea to transportation, the garden should be built in a location with convenient transportation.
Planting density should vary according to variety, rootstock and soil conditions. On fertile flat land, Chinese cherry using Y-shaped shaping dense planting, can be 1 × 3 meters, 220 plants per acre, if the use of natural bush shape or natural happy shape shaping, can be 2 to 3 meters × 3 to 4 meters. The juvenile stage can then appropriately increase the density, into the garden to take measures to deal with the deforestation.
Planting time is generally divided into two periods of fall and spring, in the winter cold, dry, windy areas should be planted in the spring, spring planting should be in the seedlings before germination. In places with warm winters can be planted in the fall.
