Can you grow cherries in Hunan?

Hunan can grow cherries, but it is not the most suitable area for growing cherries.

Cherry in China has weak cold resistance, likes warm and humid climate, and is suitable for centralized cultivation. The annual average temperature is 15 ~ 16℃. Sweet cherries like to be cold and stuffy. The natural dormancy period of cherry is about 80 ~ 100 days. The chilling requirement of sweet cherry for complete dormancy below 7.2℃ is 1 100 ~ 1300 hours. The demand of sour cherry is 1200 ~ 2500 hours.

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 you encounter "late spring cold" (frost or snow), the flower organs will be frozen, which will seriously affect the yield and even the grain will not be harvested. Therefore, we must pay attention to whether the time of high temperature and cold wave in the field can coincide with the flowering period every spring, and we should not plant cherries in the center of unfavorable weather (frost, snow and wind) at the flowering period all the year round. Even in the central area with less disastrous weather, we should choose suitable small terrain for planting when building the garden.

The annual rainfall suitable for cherry growth is usually 700 ~1000 mm. How to deal with the results of "early spring" should be fully considered when building gardens in some areas in the north. Because in the early stage of fruit growth, drought will cause serious fruit drop and affect fruit growth and development. Cherry is a light-loving tree species. China cherry is more shade-tolerant, but it has good illumination, early fruit ripening and good coloring.

Cherry is suitable for cultivation in deep, fertile and loose sandy soil. The pH value of soil is generally 6.0 ~ 7.5. ?

Planting time is generally divided into two periods: spring and spring. In cold, dry and windy areas in summer, planting in Yichun should be carried out before seedling germination in spring. It can be planted in the warm center in autumn and summer.

Before planting, the deep ploughing and maturation of soil should be stopped, and planting holes should be dug. Apply 25 ~ 50kg of inorganic fertilizer to each hole. After mixing the fertilizer with the soil, plant the seedlings and immediately water the roots.

The secondary diseases and insect pests that harm cherry trees include geometrid, moth, Cerambycidae, stinkbug, chafer, pear moth, anthracnose, cherry leaf spot, bacterial perforation, gummosis, root rot and so on, and comprehensive measures should be taken to prevent and control them. When pruning in summer, cut off the branches of diseases and insect pests and burn them, and spray Bubomei 5 degree stone sulfur mixture once when falling leaves; Spraying 40% dimethoate 1200 times solution and 70% thiophanate methyl 800 times solution each 1 time before the leaves of spring shoots stop growing; In July and August, spray 50% marathon emulsion with a ratio of 1000 and 65% zineb with a ratio of 400-500 once each.
