Introduction of breeding methods and breeding methods of lavender

Lavender is a species of lavender native to the Mediterranean coast, Europe and Oceania. Many of our friends love lavender products. Do you want to know how lavender is grown? This is a small book suitable for everyone. The breeding methods and methods of lavender were introduced.

Lavender culture method

1. spring management

Newly planted seedlings and perennial seedlings will be placed in the soil at the end of May of the following year, watered when the temperature rises, and watered with key water for seedlings and old seedlings. After a week of watering, loosen the soil and maintain the temperature. 19 kg urea, 15 kg calcium superphosphate and 30 kg oil residue were applied to 667 square meters of old seedlings. To fertilize, loosen, protect and warm, it is conducive to the growth of lavender in spring.

2. Management from growth to bloom

Newly planted seedlings should be watered with fixed root water, 4 to 5 times a year, and plowed in time. The flower buds that appear on June 20 should be destroyed in time to promote multiple branches of the plant and lay the foundation for autumn production and high yield next year. Old seedlings should be removed in the field and sprouts watered in early May. In June, flowers bloom and water.

3. Harvest at the right time

When 30% of the flowers in the field are thanked, 70% of the flowers can be harvested, generally at 10 a.m. on a sunny day is the best harvest time. Harvest time, no leaves and debris. After harvest, the flowers are transported back to the workshop for processing. If the treatment is not complete, it should be placed in an arbor to cool and keep the flowers fresh.

Lavender breeding method

Lavender breeding methods mainly include sowing, cutting, layering and rooting, mainly by cutting and sowing methods.

seed propagation

Lavender seeds are small and should be transplanted. Sowing time is generally selected in spring, warm areas can be planted from March to June or September to November each year, cold areas should be planted from April to June, lavender should be planted from May to October each year, it can be planted in winter in the greenhouse.。Germination takes about 14 to 21 days. Germination temperature: 18~24℃. After germination, it needs appropriate irradiation, and it is easy to grow in low light. The seed dormancy period is longer, and the seed is soaked for 12 hours before sowing, and then soaked for 2 hours with 20-50ppm gibberellin, and then sown. Before planting, the land is flat and fine, and water is dumped. After underwater seepage, coat the seeds evenly and cover with a thin layer of soil, 0.2 cm thick, covered with grass or plastic film to protect the raft. Keep 15~25℃, seedbed needs to be wet, about 10 days can appear. Without gibberellin treatment, it takes a month to germinate. Germination takes 1 to 3 months below 15°C. At the seedling stage, pay attention to spraying water. When seedlings are too dense, seedlings can be placed appropriately. When seedlings are about 10 cm tall, they can be transplanted.

cutting propagation

Cutting is usually done in spring and autumn. Summer branch cuttings are also available. The cutting medium can be mixed with 1/3 peat moss and 2/3 coarse sand. Select well-developed and well-growing strains, select annual semi-lignified shoots with short, thick and sprouted shoots, and cut the top 8-10 cm shoots. The incision of the incision should be close to the stem and smooth so that the phloem does not rupture. Remove the leaves from the bottom 2 parts, insert them in water for 2 hours, then insert the soil into the soil, and the roots will take root in 2 to 3 weeks. It can also choose 8~10cm annual branches, good drainage, keep wet. Rooting takes about 40 days at bed temperature of 20~24℃. Do not use terminal buds that are already inflorescences, as flowering branches are aging, which will adversely affect future growth. Cut the mulch and make the ground. After pouring, cover with film and cut immediately. The depth is 5 to 8 cm and the row spacing is 20 to 25 cm. Pay attention to improving ground temperature, promote root development; prune and lengthen branches, timely pick flower ears, promote branching, and cultivate strong seedlings. Planting distance is 60 cm and row spacing is 120 cm. Water immediately after planting.

bacterial reproduction

It can be done in spring and autumn. It is divided into 3 - 4 annual plants, divided into spring mature roots and 3-4 months, each with only bud eyes.
