Cherry varieties with large fruit, bright color and strong continuous fruiting ability should be selected for the upper basin cherry. However, you can consider planting in the park, using tiles to buckle on the drainage hole, then laying a layer of 20 cm furnace ash residue, putting nutrient soil, and finally putting seedlings. After 2 ~ 3 times of seedling raising and soil covering, the soil surface is about 5 cm away from the edge of the container mouth.
Cherry takes several years to bear fruit;
1. Generally, it takes three years for a big cherry to bear fruit for the first time. If grafting is adopted, this cycle will be greatly shortened, which depends on the choice of rootstock. Cherry in China has strong adaptability and can be planted in Jianghuai area. Sweet cherry is not suitable for planting because of its poor adaptability to wind and high temperature and humidity south of Huaihe River.
Otherwise, it is easy to cause long branches and leaves, and the fruit maturity is in the rainy season, which is also easy to cause fruit cracking and rotten fruit. The best soil is loam with good ventilation and drainage, which can keep it moist. The planting area also directly chooses frosting to avoid the wind.
2. China cherry is not dry and has many branches. Generally speaking, they use natural trees. There is no trunk or the trunk is extremely short. Cultivate 4 ~ 5 oblique main branches from near the ground, shorten the crown appropriately in winter, and choose auxiliary main branches (lateral branches). In the growth period, those with strong new shoots can pick the core early (before June), promote secondary branching and accelerate the formation of crown. Plastic surgery can generally be completed within three years.
Growth stage and time of cherry:
1, annual growth cycle and its characteristics. Cherry begins with flower bud germination in a year and goes through the processes of flowering, budding, leaf spreading, budding, fruit development, flower bud differentiation, defoliation and dormancy. This process is called the annual growth cycle. Knowing this growth and development law, we can take corresponding cultivation and management measures to meet the requirements of cherry growth and development, and achieve the goal of high quality, high yield and high efficiency.
2. Sweet cherry is sensitive to temperature. When the average temperature reached 10℃, the flower buds began to germinate (early April in Beijing). When the average temperature of that day reaches about 15℃, flowers begin to bloom (about 10 days in April in Beijing), and the whole flowering period is about 10 days. Generally, when the temperature is low, the flowering period is late, and the flowering period of big trees and weak trees is early.
