Xuan papaya propagation breeding technology

Xuan papaya propagation is mainly based on cuttings, but it can also be produced by splitting and pressing. 1, cutting propagation can be carried out in spring, summer and winter. Before the spring in February-March, the summer season in the rainy season in June-July. However, the rate of seedlings growing in winter is high. Winter plug sand bed closed moisturizing cutting method. Choose the closed moisturizing cutting method in the late autumn and early winter. At the beginning of autumn and winter, loose and fertile sandy soil was selected as the insertion bed. After the deep turning, the base fertilizer was applied and leveled. The sorghum was 58 meters long, 1.3 meters wide, and 0.3 meters deep. For cuttings, the hardwood whose diameter is 0.5-0.8 cm in diameter is selected from the last year of birth, full of development, no pests, and completely lignified, and the cuttings with more than three germinations are cut to 15-20 cm in length. Then cut the lower end near the joint into a horse-shaped slope, each 30-50 1 bundle, the lower bevel into the 50 pm rooting powder (ABT) or 5001000ppm naphthystic acid solution quickly dipping 1015 seconds, after slightly drying Cuttings. 2. Puppy breeding. The papaya sprouting force is very strong. A lot of root seedlings occur around the rhizosphere. From September to November, roots can be excavated with a seedling height of 60 cm or more, and the seedlings that grow robustly can be planted immediately. On the ground, the survival rate is high, but the propagation coefficient is low. 3. The buckling bead breeds in the spring and fall of each year. The strong, disease-free branches near the ground bend under pressure. In the soil, some twigs are cut or scratched in the soil of the twigs, fixed with bamboo rakes, and then the soil is buried tightly. Apply a proper amount of earth fertilizer. After germination, the mother is cut off, rooted, and planted separately.
