West House Breeding Three Methods

Xifu Haishu is a deciduous shrub or small tree of Rosaceae. It is a good early spring ornamental flower in the north. Its breeding is mainly based on grafting, ramets, and layering. Now it is introduced for reference. First, Grafting Rootstocks of West House Begonia are usually seedlings of M. villosa or Jellyfish, with a seedling age of 2 to 3 years and a ground diameter of about 0.5 cm. The stock can be sawn short in mid-July, leaving only 8 to 12 centimeters above the surface. One month later, thick budding shoots were selected from the strong branches of the current year in the West Bank of Japan. They were peeled off from their mother plants, and they were cut into "T" shape at the smooth part of the rootstock with a bud knife, and "T" shaped with the tip of the knife. The bark of the vertical incision is split open, the buds are embedded in it, and the upper cut surface of the bud is flush with the "T"-shaped transverse incision. Then use a narrow plastic band for binding and bind the soil to moisturize. After 20 days, no buds or necrosis were found on the sprouts, indicating that they have survived and the plastic tape can be untied. Second, bead propagation In early July, one-year thick, disease-free shoots were selected from the mother plant of the West Bank. The part of the skin that will be pressed into the soil will be injured and pressed with the soil so that the pressed branches become "" shaped, the branches are exposed, upright, and then watered. Every two or three days later, water once, so that planting soil is often kept moist. The second year of the spring before germination from the mother plant colonization. Third, ramets breeding Early spring in March, before the plants have not sprouted, the sprouting saplings next to the old plants were cut from the mother plants with a knife (roots required), and the implants were excavated in advance and applied with fermented rot. In the planting pits, after irrigating the water, the shading is appropriate and the soil is kept moist. After 15 days, it enters normal management. China Agricultural Network Editor
