Cherry can be planted in Henan, but try to avoid planting in places with wind disasters. Cherry in China likes warm and humid climate, and has weak cold resistance, so it should be cultivated on fertile, loose and deep sandy soil with annual average temperature 15- 16℃, and the soil pH value should be 6.0-7.5. The planting time is divided into autumn and spring, and it is planted in cold, dry and windy areas in Yichun in winter. The planting time in spring is before the seedlings germinate, and it can also be planted in autumn in warm places in winter.

1. Can cherries be planted in Henan?

1, cherries can be planted in Henan, and it is necessary to avoid planting in places with wind disasters. China cherry has weak cold resistance and likes warm and humid climate. They are suitable for planting in fertile and loose sandy soil with annual average temperature 15- 16℃ and soil pH of 6.0-7.5. Sweet cherries like to be cold and dry. The natural dormancy period of cherry is about 80- 100 days. The chilling requirement for sweet cherry to complete dormancy is below 7.3℃ 1 100- 1300 hours, and that for sour cherry is 1200-2500 hours.

2. Cherry planting time is generally divided into autumn and spring. It is planted in cold, dry and windy areas of Yichun in winter. It should be planted before the seedlings germinate in spring and in warm places in autumn and winter. Planting density varies according to rootstocks, varieties and soil conditions. Before planting, the soil should be deeply turned and matured, and large planting holes should be dug, and 25-50 kg of organic fertilizer should be applied to each hole. After mixing fertilizer with soil, seedlings should be planted and root water should be poured immediately.

Second, the cultivation techniques of cherry

1, cherry must be matched with pollinated varieties with consistent flowering period and strong affinity, which can be planted before and after defoliation in autumn and before germination in the following spring, and autumn planting is suitable. According to cherry orchard's soil, climate, water conservancy and topography, dwarfing ability of rootstocks, variety characteristics, overall management level and pruning methods.

2, young trees and early fruit trees, mainly apply sufficient base fertilizer, young trees should be topdressing 1-2 times of nitrogen fertilizer, early fruit trees can be forced to apply nitrogen and phosphorus fertilizer 3-4 times a year, and the big trees that bear fruit generally apply fertilizer 4 times a year. From September to June every year, 65438+ 10 is combined with deep excavation and reaming. After the fruit is harvested, it is an important period for flower bud differentiation and tree recovery. This watering should be controlled and coordinated with fertilization and irrigation to lay the foundation for high yield in the coming year. Freeze the water before defoliation and soil freezing to keep the soil humidity and temperature relatively stable and protect the roots from freezing damage.

3, shaping and pruning, spindle-shaped stems are 40-60 cm high and trees are 3-4 meters high. There are 10- 15 main branches on the central trunk with an opening angle of 70? -80? . The sparse-layer stem with small crown is 40-50cm high, and the whole tree has 5-6 main branches and a central trunk, which is divided into two layers, and the interlayer distance is 120- 150cm. In the young tree period, the crown should be expanded, the skeleton of the tree should be cultivated, and the strong should be restrained and the weak should be strengthened.

4. The bell buds of pollinated varieties should be collected at the flowering stage to make mixed pollen, and artificial pollination should be carried out at the early flowering stage and the full flowering stage respectively, or artificial pollination should be carried out by bouncing and rolling on different varieties of trees with a feather duster from 10: 00 to 17: 00 every day.
