After the cherry is harvested, the peel and pulp are cut to take out the stone, and the pulp attached to the stone is washed away with clear water, and then the cherry is dried in the shade for 1 ~ 2 days before sowing. When sowing, the seeds are directly sown in shallow pots, and germinate about 10 ~ 30 days after sowing. When the seedlings grow to 5 ~ 250 px, transplant them into plastic soft pots. Cherry seeds are easy to germinate, but the germination is irregular. Some plants often lack viable embryos, and the germination rate is often lower than 30%. The results of seedling raising method are late and the quality difference between seedlings is great.

Cutting method

In the spring and summer growth period, select semi-mature robust branches with a diameter of 0.7~30px and a length of 15 ~ 500px, and insert them into river sand, vermiculite, peat soil or several mixtures, which are all suitable as seedbed substrates, especially the cuttings should be kept moist and shaded. Rooting takes about 1.5 ~ 2 months after cutting, and transplanting is carried out after the root group grows vigorously. If face-to-face management is adopted, the survival rate is about 60 ~ 90%. The cutting method is simple and the success rate is the highest.

High altitude stratification method

Select branches for more than two years, and peel them annularly at the lower part near the node (destroy the phloem of this part and promote the cambium rooting above this part), then put wet wool into a transparent plastic bag to wrap the whole wound, and tie the upper and lower ends together. When it takes root, it is cut below the layering position and potted into new plants. Generally, cherry is selected in the vigorous growth period (late spring and early summer), which is easy to take root. Although rooting is easy, the effect varies from variety to variety.

Grafting method

Cherry grafting takes cherry seedlings, cherry blossoms, cherry blossoms, etc. As rootstock, excellent cherry varieties as scions are selected before germination in spring. The best rootstocks and scions are the same or similar in thickness and can be used for splitting or butting. When the grafting method is adopted, the upper part of the grafting part on the rootstock is selected, the redundant branches are cut off with sharp scissors, the remaining "piles" are split with a knife, the opening depth is about 2-3 cm, and the length of the scion is about 10 cm, and the scion is quickly cut into two sides and inserted into the split mouth; After the molding layer is aligned, it shall be firmly bound with plastic film strips, and there shall be no air holes. First of all, put it in a cool and ventilated place, sprinkle water on the ground to keep the environment high and humid, or use plastic bags to keep it moist, and then ventilate it in time according to the temperature change, so as not to let the temperature in the bag be too high. Plastic bags should be removed when new buds grow. Move the plants to a sunny place. It is wise to water between dry and wet.
