Can the climate in Chongqing grow cherries?

Cherry (big cherry) planting is suitable for climate;

1. Young cherry trees are weak in cold resistance and prefer warm and humid climate, so they are suitable for cultivation at the place with annual average temperature of 15 ~ 16℃. The dormancy period of cherry seedlings is short. The temperature warms up in late winter and early spring, and it is easy to sprout new buds. If the organs of flowers are frozen in late spring (frost or snow), it will even seriously affect the yield or even the grain harvest.

2. Therefore, in planting, we must pay attention to whether the time when the local cold wave strikes in spring coincides with the flowering period, and we should not plant in places where adverse weather (frost, snow and strong wind) occurs during the flowering period of cherry blossoms all the year round. Even in places where disastrous weather rarely occurs, it is necessary to choose suitable small terrain for planting when building gardens. Compared with real cherry, Prunus tomentosa has strong cold resistance and is suitable for planting in Northeast China.

3. The annual rainfall suitable for the growth of cherry seedlings is generally 700 ~1000 mm.. How to solve the problem of "spring drought" should be fully considered when building gardens in some areas in the south. Because in the early stage of fruit growth, drought will cause serious fruit drop and affect fruit growth and development. Cherry seedlings are light-loving trees, while China cherries are more shade-tolerant, but with good light and early fruit ripening.

Chengkou County, Chongqing also has successful examples of planting:

1. Chengkou County belongs to the northern subtropical mountainous climate and has the characteristics of three-dimensional mountainous climate. The annual average sunshine hours 1534 hours, with large temperature difference between morning and evening, are suitable for cherry planting requirements.

2. For this reason, Chengkou County carried out the experiment of grafting cherry with cherry tree as rootstock in 2007, and achieved certain success. In order to quickly expand the planting area and improve the planting efficiency, Chengkou County directly introduced virus-free cherry seedlings and planting techniques from Shaanxi on 20 13, and established a cherry science and technology innovation demonstration park in Pingba Town, and planted more than ten varieties successively. Under the careful guidance of experts, through the observation and test of variety characteristics, the early, middle and late ripening high-quality cherries suitable for natural conditions in our county were screened out, and a demonstration planting base of more than 300 mu of scientific and technological cherries was established. In May, 20 14, more than 50 acres of cherries began to bear fruit, picking about 1000 kg, and the average selling price was 80 yuan/kg. A cherry was planted at the fruit maturity. It has attracted many citizens to take pictures and stop to watch the picking, which is deeply loved by consumers. It is estimated that the cherry in the park will be listed in high yield in 2065 438+05-2065 438+06.
