What do you need to pay attention to when planting cherries?

1. Choose a place to build a garden. "Chinese cherry" can grow normally when the average annual temperature is above 15-16 ℃ and the annual rainfall is between 700-1000 mm. Although the varieties of "Chinese cherry" are more shade-tolerant, they still need to be planted in places with good light in order to achieve early fruit ripening, good coloring and high yield. Cherry is suitable for loose, fertile and deep sandy loam, and the pH value is between 6.0 and 7.5. Heavy clay needs to be improved for ripening to grow cherries. When planting cherries on hilly slopes, you should choose the leeward slope or the base of the hills. Before planting seedlings, trenches or excavated planting holes should be adopted to improve the soil, and enough organic fertilizer should be applied as base fertilizer.

two。 Do a good job in plastic surgery and pruning. Cherry is suitable for cluster shape, trunk sparse layer shape, happy shape and so on. According to our experimental observation, the Y-shaped tree (or V-shaped) can not only bear fruit early, but also easy to manage, but also conducive to meet the lighting conditions of the tree, so as to improve the quality. The characteristics of the Y-shaped tree are: the dry height is 30-50 cm, the two main branches of each plant are symmetrical on both sides, and the angle between the main branches is 45-60 degrees. The height of the tree (the height at which the main branch extends to the end from the ground) is about 2 meters. There are 7-10 medium-sized branches on the same side of each main branch, the leaf area coefficient is 5-7, and the thickness of leaf canopy is 40-60 cm. Maintain a 0.8-1.2 meter clear path between the lines.

3. Covering and moisturizing can not only prevent cracking but also increase the fruit. The management of "soil, fertilizer and water" of cherry focuses on the regulation of soil water and fertilizer from flowering to ripening. Therefore, under the premise of not causing too much water, we should supply moist soil as much as possible and increase the fruit. However, excessive rainfall or irrigation will cause shoots to grow and aggravate fruit drop and fruit cracking. According to the experimental observation, by adopting the measure of "irrigation plus mulching" in spring, the fruit setting rate can be increased by 17.8%, the fruit is 14.8% higher than that of the control, and the average weight of a single fruit is increased by 0.6-1.2 grams.

4. Young trees supplemented by artificial pollination have the effect of increasing production. Artificial pollination is an important measure for high yield and high quality of cherry. The germination temperature of dormant bud of cherry is lower, and the flowering temperature is also low (about 11.8 ℃). In some years, the temperature rises slowly after flowering, and poor pollination and fertilization will occur in the areas where honeybees are the main flower-visiting insects. When the temperature is below 14 ℃, the activity of honeybees is weak, which hinders pollen transmission. The yield increase effect of artificial pollination (especially young trees) is very ideal. Spraying the mixture of urea, potassium dihydrogen phosphate and borax for 1-2 times from the early flowering stage to the full flowering stage has a good effect on fruit setting.

5. Harvest in time. Fresh cherries should be harvested as fully as possible, because cherries continue to grow during the maturing period, accounting for 23% and 37.8% of the total. At the same time, only the ripe cherry fruit can reflect the flavor characteristics of this variety.
