Species generalization
Cherry, also known as Big Cherry, Han Tao, Tao Jing and so on. , is the earliest tree fruit on the market, and is known as the first branch of 100 fruits. It is said that orioles especially love pecking this fruit, so they are also called cherries. Although its fruit is as small as a pearl, its color is bright, exquisite as agate and precious stones, and its taste is sweet with a hint of sour taste. It can be eaten fresh, pickled or used as an ornament for other dishes and foods.
Cherry in China is weak in cold resistance, and likes warm and humid climate, so it is suitable for cultivation in the place with annual average temperature 15 ~ 16℃. Sweet cherries like to be cold and dry. China cherry has a short dormancy period, and it is easy to germinate when the temperature warms up in late winter and early spring. If it is cold, frosty or snowy in late spring, the flower organs will be damaged by freezing, which will seriously affect the yield and even fail to harvest the grains.
Therefore, in the development, we must pay attention to whether the time when the local low-temperature cold wave strikes in spring coincides with the flowering period, and we should not plant it in places where frost, snow, strong wind and other adverse weather occur in the flowering period of cherry all the year round. Even in places where disastrous weather rarely occurs, we should choose suitable terrain for planting when building gardens.
