Spring flowers breeding technology

The spring flowers are deciduous shrubs of the family Oleaceae. The stems are thinly tetragonal, the dark greens are brown, and the leaves are greenish. The flowering period is from January to March, and thus it is known as the "Spring in the Snow." Spring flowers are cultivated in various parts of China because of their strong adaptability to the soil, drought tolerance, cold resistance, pruning, and wide application. The spring flowers have strong sprouting roots. The general breeding methods include cutting methods and pressing methods. The rooting of cuttings in the water is also a breeding method. The introduction is as follows: I. Water insertion time: water can be inserted all year round In winter, the container for water can be placed in the room to the sun. In summer, it is necessary to pay attention to shading and prevent the sun from shining. Water temperature should be maintained at 15 °C to 20 °C during plugging, and the cuttings should be rooted quickly and have a high survival rate. Second, the cuttings of water plugs: cuttings selected strong growth of the year, buds full of branches, cutting length is generally 8 cm to 12 cm, can stay 2 to 4 knots. Cut about 2 mm from the bottom section of the next section. If there are too many blades in the top half of the cuttings for every 10 bindings, they can be removed properly to facilitate rooting. Third, the water inserted containers: containers for larger diameter pots or shallow bottom wide mouth bottles, etc., must be washed before use. Fourth, water plug method: the container contains clean rain, river water or tap water, as deep as 8 cm to 10 cm, then put the bundled cuttings into the water, the depth of the water is 4 cm to 6 cm, and then put the container In outdoor ventilation and half shade, the water quality must be kept fresh and clean, and the water can be changed every 3 to 5 days. After about 20 days, a tumor-like healing tissue can be produced, and fibrous roots can be grown from 35 days to 40 days. V. Timely planting: When the fibrous root grows to 3 cm to 5 cm, it must be planted in time. Pay attention to the operation carefully, do not damage the root system. Normally, after the plant is shaded for about 10 days, normal management can be performed.
