How to Propagate Syringa Villosa
Syringa Villosa grows strong and has a beautiful color and a fragrant smell. Its resistance to pests and diseases is relatively strong, for air pollution, dust and hydrogen fluoride, sulfur dioxide and other toxic gases have a strong adsorption capacity, so it is very suitable for greening tree species. Syringa Villosa can be propagated by sowing, cutting and grafting. Here is a brief introduction to Syringa Villosa's propagation methods.
Sowing propagation methods of Syringa Villosa
1. Sowing time
Syringa Villosa seeds can be planted in the spring, which is a good time for seed germination and growth.
2. Seed preparation
In August, when the seeds of Syringa Villosa are green, it is best to harvest them early and immature, and the seed coat will burst and the seeds will fall off late.
Flowers can be collected in a well-ventilated bag and placed in a lee to the sun. When the seeds of syringa villosa are dry, they can be stored in a cool, dry place.
3. Seed treatment
If the seeds of Syringa Villosa need to be soaked before sowing, the seeds of Syringa Villosa should be first removed from the seed shell and impurities, and then soaked in cold water at room temperature for 48 hours. The water can be changed every 12 hours.
If it is easy to occur in the gold needle, mole cricket seedbed seeding, can use Cobaweir, concentration of 35% for pesticide seed dressing, and can also prevent and control other underground pests.
4. Sowing method
The sowing time of Syringa Villosa is from April 25 to 30, the sowing amount is about 3.0g/m2, and the sowing should be evenly spread on the bed surface, covered with fine soil, and the thickness is 0.5-1.0cm. To be timely watering, watering time for the morning before 9 o 'clock, after 3 o 'clock in the afternoon.
Artificial watering to use a fine eye watering can, mechanical watering should be done drizzle shape, but can not cause soil loss accumulation, must always keep the bed surface wet.
5. Post sowing maintenance
Syringa Villosa seeds usually germinate after two or three days of planting. When the leaves come out after six or seven days, they need to be weeded because the seedlings are small and delicate, but they must not be damaged.
Remove weeds in time, appropriate thinning, so that the distribution of seedlings is uniform, when the seedlings grow to L0 ~15cm for plant selection, in addition to weak growth, there are diseases and insect pests of the seedlings, retain the density of 40~50 plants /m2, do a good job of fertilization and watering.
Cutting propagation method of Syringa Villosa
Cutting propagation method of Syringa Villosa can be 1 month after the flower, choose the year born lignified robust branches as cuttings, cuttings about 15 cm long, in 2 ~ 3 pairs of buds. After cuttings were cut, they were treated with 50 ~ 100 mg/L of indolebutyric acid for 15 ~ 18 hours, and then inserted in a plastic film covered sand bed for 1 month. Cutting can also be in autumn, winter take lignified branches for cuttings, first exposed buried soil storage, next spring cutting.
Grafting propagation method of Syringa Villosa
Rootstock is mostly European lilac or leaflet privet, which can be sprouted or grafted.
1. Bud grafting, generally in late June to mid-July, choose the sleeping bud on the healthy branch full of bread as scion, with no xylem shield bud grafting method, received from the ground 5 ~ 10 cm high stock dry stem, winter attention to protection.
2. Branches, in the autumn, winter article, spring of the next year, after the outdoor buried directly to survive a scion that germinate and up to 50-80 cm long, but should tip small flower bud formation. Therefore, it should be before the second year sprouts are cut short stems from the ground 30 ~ 40 cm, to promote the germination of the collateral, mature and normal flowering branches. Grafting plants to live, promptly cut out the rootstock sprout tillering.
