The cuttings are treated from mid-October to early November, combining the wintering of the Chinese rose to prune twigs with well-proportioned and cryptic buds during the selection period, removing the leaves, cutting into 10 cm long (about 3 knots) cuttings, and cutting at the top into flat mouths. Sealed with lacquer, the lower end cut into a ramp standby.
Seedbeds and nutritional bags are prepared to be leeward, sunny, flat, and loosely soiled with a bed that is 1 meter wide, 5-6 meters long, and 20-30 cm deep. The cooked nutrient soil and fine sand soil were mixed and blended with each other. The nutrients were disinfected with zincphosphorus and carbendazim and then placed in a nutrition bag. It was also possible to store the nutrient bag directly on the seedbed.
When inserting and inserting, the nutrition bags are placed one by one on the seedbed. Grate with a wooden stick or chopsticks, then insert the cuttings, depth 1.2-2/3, compaction. Note: Do not plunge down, prick the spine downwards, shoot upwards, water while inserting, and pour water after inserting. Then, stick a wooden stick on the seedbed, cover the film, and press it with the earth for four weeks.
In late March to early April, the cuttings were about 1 cm in length and susceptible to locust infestation. They should be guarded against locusts and fumigate with 80% dichlorvos, that is, 2 squares to insert five cotton balls with a diameter of about 0.6 cm. , 2 hours removed. After 1 week of observation, if there is insect reinsertion. At this time, special attention should be paid to insect pests, otherwise it would be extremely harmful to seedlings.
Precautions. Winter cuttings, cold and heat-resistant, can not be put into the greenhouse after the spring. In 4-5 months, the pot or land was planted and normal maintenance was performed.
