Where is cherry suitable for planting?

1, the time when the daily average temperature is higher than 10℃ is 150-200d, and the place where the extreme minimum temperature in winter is not lower than -20℃ can grow well and have normal results.

2. If there is freezing damage in the local area, cherry orchard can choose the northwest slope where the temperature rises slowly in spring and the air circulates. Considering that the cherry root system is shallow and easy to be blown down by the wind, the garden should be in an area free from wind damage, and the soil is sandy loam with loose soil and deep soil layer.

3. It is suitable to grow under the climatic conditions of annual average temperature 10- 12℃, annual precipitation of 600-700 mm and annual sunshine hours of more than 2,600-2,800 hours. ..

The main causes of cherry blossom and fruit drop

1, single cultivated variety or improper pollination tree configuration.

Most varieties of big cherry can't bear fruit by themselves. Single variety, lack or improper allocation of pollination trees and incompatibility of pollination will affect the quality of pollination and fertilization, resulting in only flowering and no fruit setting.

2. Malnutrition of trees

Low soil organic matter content, shallow roots, hindered growth and development, lack of stored nutrients in trees, and decline in tree vigor and nutritional status will all lead to the reduction of fruit-setting clusters.

3. The temperature and humidity control is unreasonable

If the temperature before and after flowering is too high, and the daytime in the shed exceeds 25 degrees Celsius, the flower organs will be injured, the branches will shrink and dry, the effective pollination time will be shortened, the pollen vitality will be reduced, the young fruit will develop slowly, and the new shoots will be white and long, which will aggravate the physiological fruit drop. When the humidity is too high at flowering stage, it is also easy to cause pollen to absorb water, become inactive or sticky, and it is difficult to spread, thus affecting fruit setting.

4, extensive management, serious pests and diseases.

Occurrence period of pests and diseases; Failure to master the law and the best control period, and not knowing the scope and object of pesticide control often lead to serious gummosis, perforation and early defoliation, reducing the accumulated nutrition of trees.
