Mainly cutting and seeding method.
small lavender seeds, seedlings should be transplanted. Sowing the general election in spring, warm areas in each of 3 to 6 months or 9 to 11 month, in cold areas should be planted 4 to 6 months, winter can be planted in the greenhouse. Germination about 14 days to 21 days. Germination optimum temperature: 18 ~ 24 ℃. After germination in need of appropriate light, weak light and easy leggy. Seeds for a longer period of dormancy, soaked 12 hours before planting, then 20-50ppm GA soaking 2 hours and then sown. Small flat before sowing the land, irrigated until the water infiltration, the uniformity of sowing the seeds, then covered with a layer of fine soil, thickness of 0.2 cm, covered with grass or plastic film moisture conservation. Maintain the 15 ~ 25 ℃, wet seedbed requirements, the emergence of about 10 days. If you do not Gibberellin will have one month before being germinated. To be lower than 15 ℃ 1 ~ 3 months to germinate. Note seedling water, when the seedling thinning may be appropriate when too dense, to be about 10 cm height can be transplanted.
cuttings generally in the spring and autumn. Softwood cuttings in summer can be. Cutting medium available 2 / 3 coarse sand mixed 1 / 3 peat moss. Plants healthy and vigorous development of improved varieties selected, select the heading, pitch and not a short stout semi-woody branches, annual terminal bud at the top of the interception at the 8 ~ 10cm cuttings. Stem node cuttings near the incision should be at, and strive to smooth, without rendering phloem rupture. The bottom two leaves removed, inserted 2 hours before cutting the water in the soil, about 2 to 3 weeks will be rooting. 8 ~ 10cm is also optional one-year old branches, in well-drained, moist, 20 ~ 24 ℃ under the conditions of bed temperature, about 40 days to take root. Do not use the terminal bud has emerged inflorescence cuttings, because the flowering branches are aging, will adversely affect future growing root hair. Film cutting, site preparation Zuoqi. Irrigated after the film, immediately cutting. 5 to 8 cm deep, spaced 20 ~ 25cm. Attention to increasing temperature, promote root growth; Kan extension of branch pruning, removal of spikes in time to promote branching, nurturing seedlings. Planting and plant spacing 60cm, spacing 120cm. Watered immediately after transplanting.
spring and autumn can be carried out, with 3-4 year old plants in the spring from March to April with the adult and old root partition, each branch with a bud eye. How to scent the air
Lavender Lavender is a valuable natural aromatic plants. The spikes made by refining oil, the aroma of fresh, sweet and pleasant, is the perfume industry, one of the important natural raw materials.
1, elected to land preparation: Lavender likes the sun, heat, cold, Low, saline-alkali, selected before the cultivation of land, enough fertilizer, irrigation enough water, the whole good land, soil preparation may request Zuoqi. And herbicide treatment on soil insecticide Miebing.
2 planting methods: lavender are sowing, cuttings, layering, split-root of four, mainly in the production of cutting approach, the general election in the spring. Select the heading of the pitch is not cutting short stout semi-woody annual shoots, in the top 8 to 10 cm interception as cuttings. The incision should be close to the internode at the incision should be spread around the callus corrosion film to protect the integrity of the phloem, and 800 times with a new lipid membrane soaked cuttings (anti-ulcer wound rot, viral infections, restore vigor of plant physiology, germination and promote seedling root) .
3, seedling management: seedling to the soil moisture level of appropriate, adequate soil fertility to maintain temperature, high-fat to spray the new film, heat preservation of soil moisture to promote root development. Growth stage to flowering stage management, should be diligent and timely removal of pruned branches extending spikes, promote branching, nurturing seedlings, and promote healthy plant growth and multiple branches. Old seedlings on land to do field without weeds, in early May to the water pouring good bud, good flowering in June pouring water, lavender, rich colors, fragrance bursts, attractive, strong in the flower bud of the City Spirit of spray can promote strong bud, petal hypertrophy, beautiful color, rich fragrance, flowering extended.
4, pest control: spider mite and aphid pests, diseases are root rot, control methods: spray targeted high-fat plus new film, greatly improving the rate of pesticide active ingredients. Disease are also prone to spider mite control methods are as follows: early flowering, with 800 times the general tree protection spray carefully, leaves and flowers 10 days after the separation and then spray again, the better.
