Fringe trees can be propagated by sowing, cutting and grafting. Sowing and cutting propagation are the most commonly used because they are easy to do and can produce a large number of seedlings at once.
When we carry out Fringe tree sowing propagation in autumn, a forehead-covering Tree will have blue-purple fruit. Seed at this time should be harvested from a strong, well-formed parent plant that is free of pests and diseases. Choose the full, the same size of seeds soaked in water for 2 days, after the fish dry in a cool and ventilated place. After 3 days, wet sand was used for storage, with a sand-seed ratio of 3:1, and a sack was covered for moisture preservation.Seed storage period, every half a month for sprinkling over a mix. It is better to spray water with sand moist, too much water easily leads to seed decay.
The next year in the middle of spring, about 40% of the seed white can be carried out whole bed sowing.The nursery site should be deep and fertile with good drainage. Generally, high ridge seeding with ridge spacing of 625px and ridge height of 375px was adopted. Use the fermented cattle and horse manure as the base fertilizer, the dosage is 3000kg per acre, the depth of the seeding ditch is 50px, and the row spacing is 500px. The seeds that have been accelerated to sprout are evenly sown in the seeding ditch. The sowing amount of mu is about 20kg. After sowing propagation of Fringe tree, it is covered with fine soil, after gently and steadily, the irrigation is permeable once, and the grass is covered with moisture three days later.(www.66077.cn) About 25 days after sowing, seedlings begin to emerge.When seedlings grow to a height of about 250px, choose cloudy days for thinning. When the summer light is strong, it is necessary to cover the shade in time for shading, and after the heavy rain, it is necessary to remove the water in time in the garden. Thereafter, in the management, to keep the nursery soil was more than half the soil moisture, and strengthen the middle tillage weeding.
Fringe tree cutting propagation is generally carried out in summer, select the semi-lignified branches that were born in that year, and cut them into 300px-375px cuttings. The upper cuttings are flat, and the lower cuttings are horseshoe shaped. Matrix choose silty loam, nitrobenzene chloride with five disinfected before use, make a flood irrigation after disinfection, to the substrate is much quantity, can be cutting, cutting cuttings before touching ABT rooting agent, plant spacing is 250 px by 500 px, cutting every 7 days after pouring a permeable, morning and evening on a spray, 9 to 18 PM to shade, before winter in soil with a horses and cattle dung, water drenched the freezing water, set-up tunnel with plastic film, to facilitate its safety overwintering. The second year to strengthen the management of water and fertilizer, the third spring can be transplanted.
