1, save seeds
First of all, we need to get healthy full organic cherry seeds, just eat some cherries, you can get the natural kernel, and then put these cherry kernels in warm water for 5 minutes, you need to clean all the pulp residues on the kernel.
After the preparation of some paper towels spread on the desktop, will be cleaned and soaked cherry kernels loaded up, placed in a ventilated warm place to dry for 3 to 5 days, such as the kernel after drying, it is necessary to put the kernel into a washed and clean, with the lid of the container, which can not have water, and then will be sealed in the bottle in the refrigerator to save about 10 weeks of time. Because cherry pits need a period of cold dormancy before they can germinate, in their natural environment they germinate in the spring after a cold winter. And we put the kernels in the refrigerator to simulate a cold winter, and after 10 weeks they are ready for seed propagation.
2, sowing preparation
10 weeks after the cherry kernel will be taken out, and then placed at room temperature, ready to sow containers, to be smaller containers with good drainage, the soil should be loose and breathable and well-drained, to avoid stagnant water in the potting soil, the small container is easy to cultivate, to avoid rotting roots. Want cherry pits to germinate and root as soon as possible, you also need to prepare a pair of tongs, remove the shell of its pits, reveal the white germ inside, plant the germ in the soil, so that it can germinate faster.
3, keep the soil moist at all times
Put the kernel directly under the soil, water it thoroughly after shallowly burying it, keep the soil slightly moist during the maintenance period, and you can put it on the window sill, ventilated and brightly lighted place. You can put more than one kernel in a small container, and when the seedlings grow to 2~3 centimeters, remove some of the weaker seedlings and let the strong ones grow in small pots.
4, late maintenance attention
Seedlings grow out after it will be placed in a sunny place, until the frost outside the past, after the warmth of the warmth, you can put the seedlings in the outside of the maintenance, which is more conducive to the growth of cherry seedlings, and then the amount of watering can be appropriately reduced.
If you want to plant cherry trees in the ground at a later stage, you need to plant them 6 meters apart to avoid planting them too densely. Cherry tree growth needs regular fertilization, and then pre-growth is mainly to promote the growth of branches and leaves, pre-low nitrogen fertilizer-based.

Management points of cherry trees
1, cherry tree branch pruning management
After the cherry harvest, those who grow too dense branches, thin and weak branches, whiplash branches, and diseased and insect branches, should be thinned out or cut off in order to open up the light path, enriching the branches, reducing unnecessary consumption, and is conducive to Flower bud differentiation and branch maturation. And apply a healing antiseptic film to the wound to protect the wound from rapid healing and isolate viral infection.
2, cherry tree pulling management
Cherry harvest can be a small angle of the first branch of the large branch pulling, so that the angle of the main branch and its angle of 70 ~ 80 degrees. Can improve the tree ventilation and light condition, while easing the growth potential, very favorable to bud differentiation. Note that before pulling should be in the bundling point pad injury pads, so as not to pull the big branch cortex injury.
3, cherry tree new tip centering management
In order to promote bud differentiation, to prevent excessive nutrient growth, should take the new tip centering method of control. That is, the growth of the new shoots did not stop centering, centering position is generally half a leaf as a boundary; centering after stopping 10~15 days will send out the second tip, to be its length to 15~20 cm and then a second centering, the position is still half a leaf as a boundary.
4, cherry tree pests and diseases
Peach leafhopper, also known as the floating sinker, is the main pest in the late stage of growth of cherry, July - September, the most intense damage, the victim peach leaves appear yellow-white spots, serious leaves yellow, early shedding, resulting in weakening of the tree, affecting the formation of flowers and so on, reducing the next year's output. Preventive measures are, immediately after picking the fruit sprayed 1 times 200 times Bordeaux liquid or 40% of the Lego emulsion 1000 - 1500 times liquid, combined with the spraying of the new high fat film to improve the utilization rate of the active ingredient of the agent, to consolidate the effect of prevention and control.
5, cherry tree foliar fertilizer management
Pick fruit every 10 - 15 days after spraying a 0.5% - 1% urea solution, while spraying 0.5% calcium superphosphate solution, to improve the photosynthetic capacity of the leaves, increase branch nutrition. According to the development of the tree, in the pre-bloom bud period and fruiting period, fruit expansion period of the timely spraying of strong fruity spirit, can effectively thicken the fruit (flowers), improve the amount of nutrient delivery, anti-flowering, fruit drop, cracked fruit, stiff fruit, deformed fruit, so that the fruit coloring is beautiful, beautiful fruit, good taste, and greatly improve the rate of high-quality commodities to achieve the effect of increased yields.
6, cherry tree scientific fertilization technology
The end of May to early June, strain application of organic fertilizer 50-1000kg, such as mixing 1kg/plant calcium superphosphate, the effect is better. Fertilizer method, available radial and annular alternating into the location of the periphery of the crown just below the fertilizer ditch should be shallow inside and outside the deep, so as not to hurt too much root system, followed by watering 1 time. Spraying Flower Promoting King 3 at the top of the crop can convert plant nutrient growth into reproductive nutrition, inhibit the main tip of the crazy growth, promote flower bud differentiation, more flowers, improve the quality of pollen fertilization, more flowers, more fruits, prevent fruit drop, and promote development.
