Cherry breeding method

[Agricultural] net cherry, Prunus certain plants collectively, including cherry subgenus, subgenus sour cherry, cherry laurel subgenus and so on. Let's look at the method of breeding its cherries:

Real law

After the cherries are harvested, the flesh of the peel is cut to remove the core, and the flesh outside the pit is washed with water, and then dried in a cool place for 1 to 2 days. When seeding, the pits are directly sown in shallow pots and germinated about 10 to 30 days after sowing. When the seedling grows to 5 to 250 px, it is transplanted into a plastic soft basin. Cherry seeds sprout easily, but their germination is not neat and some plants produce seeds that often lack viable embryos, often with germination rates below 30%. The results of the bio-method were later, and the quality variation between the seedlings was large.

Cutting method

During the spring and summer growth period, semi-mature robust branches are selected, with a diameter of 0.7-30 px, each segment is 15 to 500 px, and 4 to 6 leaves are attached. It is suitable for river sand, vermiculite or peat soil or several mixtures. In the seedbed medium, the cuttings need to be kept moist and shaded. Roots are taken about 1.5 to 2 months after cutting, and transplanted after the root group grows vigorously. If the cutting method is managed face to face, there will be a 60-90% survival rate. The cutting method is simple and the success rate ZUI is high.

High-altitude beading

Select the branches of more than two years, and peel the skin in the lower part of the section near the knot (destroy the phloem part of the part, and promote the formation of the root layer above the place), then put the moist velvet grass into the transparent plastic bag to put the whole The wound is wrapped and the upper and lower ends are tied together. After rooting, it is cut below the beading part and the potted plant becomes a new strain. Usually selected in the strong growth period of cherries (in the late spring and early summer), easy to root. Although rooting is easier, the effects between varieties vary greatly.

Grafting method

The cherry is grafted with cherry seedlings, cherry blossoms, cherry blossoms, etc. as the rootstock, and the good cherry varieties are used as the scion. The selection is made before the spring is not germinated. The roots of the ZUI good selection and the scion are the same or similar. Both connect and dock. When grafting with the splicing method, select the upper part of the grafted position on the rootstock to cut off the excess branches on the upper part, and use the knife to open the remaining "pile". The opening is about 2-3 cm deep. It is suitable for about 10 cm. The scion is quickly cut into two sides into a "wedge shape" and then inserted into the mouth; after being formed into layers, it is tied with a plastic film strip, and there is no air vent, first placed in a cool and ventilated place, and on the ground. Spray water to maintain high humidity in the environment, or use a plastic bag to cover the moisturizing. After that, it should be ventilated according to the temperature change. Do not let the temperature inside the bag be too high. When the sprout grows, remove the plastic bag. Move the plants to a sunny place. Watering should be wet between the lines.
