Cherry planting conditions

Cherry trees should be planted in warm and humid places, requiring loose soil, good ventilation and drainage, sufficient light to ensure proper amount of water, not too dry and not too wet, so as not to affect the growth of cherry trees, when the winter temperature is low, lime solution can be smeared on the trunk to help cherry trees survive the winter, in the process of planting, it is best to build windbreaks in windy areas to prevent cherry trees from getting sick. To ensure the normal growth and development of cherry trees.

At present, the cherry varieties planted in China are mainly European and American varieties. European cherry varieties need to grow at a low temperature below 7.2℃ for 900-1400 hours to complete the necessary winter dormancy, so they are mostly planted in the north of China. Chinese cherry is mainly planted in the south of China, except black pearl, there are few excellent varieties of Chinese cherry, the cherry fruit planted is generally small, the fruit sweetness is low, and there are cracking and falling fruit before picking.

1. The area where cherries are planted

Cherries have higher requirements for temperature but are not resistant to cold. They belong to deciduous fruit trees. Chinese cherries originating in the Yangtze River Basin in China have to live in a warm and humid environment and have poor ability to resist cold. Therefore, they are mostly planted in the Yangtze River basin and northern microclimate and warmer areas.

It is easy to grow sweet cherry and sour cherry in the north, northwest and south of northeast China. The dry and hot weather in summer is not conducive to the growth of cherry. The lowest temperature in winter should be above minus 20 ℃, so as to avoid too low temperature causing a large number of cherry trees to crack and glue in the night. Flower buds are fragile, cherry trees will suffer frost damage as long as the temperature of the growing environment is below minus 3 ℃, so try not to choose areas with lower temperatures when planting cherries.

2. Lighting requirements

Good light can promote the growth of cherry trees, prolong the life span of fruit branches, enrich the development of flower buds, increase the fruit setting rate, accelerate fruit ripening, improve fruit quality, good coloring and high sugar content.

If the light is not enough, the cherry trees will grow too long, the inner branches on the crown will be weak, shorten the life of fruiting branches, affect the development of flower buds and fruit setting rate, resulting in poor fruit quality. The density should not be too high when planting, make sure the branches can open as much as possible, and ensure the light conditions in the canopy to ensure adequate light and ventilation.

3. Soil selection

Cherry planting soil to go deep and fertile, loose soil, with good air permeability and drainage, cherry trees are more sensitive to sudden salinity, in planting to avoid choosing saline-alkali land, the soil PH value had better be controlled between 5.6-7, if the soil salinity is too high, will reduce the survival rate of ancient trees, is not conducive to management.

4. Moisture requirement

Cherries have higher requirements for water, they are not resistant to drought and waterlogging, except for some southern provinces with sufficient rainfall in our country, cherry growers in northern China mostly choose to plant in the humid areas of hillside ditches and microclimate.

Whether growing cherries in China or overseas, they generally choose to grow in coastal areas, where the temperature is suitable, the light is sufficient and irrigation is convenient, which is conducive to the growth and development of cherries, but also improve the yield and quality of cherries.

Although cherries like moist growth environment, too much water will lead to insufficient oxygen in the soil, affect the normal respiration of roots, affect the growth and development of cherry trees, cause rotting roots, glue flow, and even lead to cherry tree death.

5. Cherry trees overwintering

Although cherry trees are relatively easy to grow, the branches of cherry seedlings are not resistant to freezing. If the winter temperature is too low, the young cherry trees will become dehydrated, wrinkled and dry. Generally, the young cherry trees will strip in winter, and the lighter ones will change the shape of the cherry trees and affect the early fruit.

In winter, in order to help cherry trees survive the winter smoothly, you can use quicklime and water to make lime paste, and then add some salt to it to evenly whiten the trunk, which can reflect the sun's light to a certain extent and prevent excessive temperature difference between day and night from causing damage to trees. in winter, you can also slightly cut off the trees with large transpiration, and apply Vaseline to the cut to reduce water loss.

6. Disease prevention

Cherry trees are easily infected by root cancer bacteria and nematodes in the soil. There are more root cancer bacteria in the soil of old orchards where cherries have been planted, which is not suitable for planting cherries and developing cherry nurseries, so that cherry trees will not be infected with root cancer and cause losses.

Cherry root distribution is shallow, the resistance to the wind is poor, it is easy to dry paper in winter and early spring, flower buds will be frostbitten, if the wind will blow away the stigma mucus, so that insects can not pollinate. Typhoons in summer and autumn will cause branches to fall, resulting in greater losses. If there are often strong winds in places where cherry trees are planted, wind forests should be built to ensure the growth and development of cherry trees.
