Lavender is a semi-shrub or

Dwarf shrubs, branched, stellate tomentose, dense in young parts; The old branches are grayish brown or dark brown, the cortex is stripped in strips, the flower branches are long and the regenerated branches are short. The leaves are linear or lanceolate, and the leaves on the flowering branches are large and sparse.

Free, 3-5 cm long, 0.3-0.5 cm wide, densely or sparsely covered with gray stellate villi, grayish white or olive green when dry, and leaves on regenerated branches are small and tufted, with the length not exceeding 1.7 cm and the width about 0.2 cm.

M, densely covered with gray-white stellate villi, gray-white when dry, blunt at the apex, tapering at the base to a very short stalk, entire, with the edge rolled outwards, protruding below the midvein, and the lateral veins and reticular veins are not obvious. [2]

A verticillate plant usually has 6- 10 flowers, most of which are clustered into discontinuous or nearly continuous spikes at the top of branches. The spike is about 3(5) cm long, the peduncle is about 3 times as long as the inflorescence itself, and it is densely covered with stellate villi. Bracts rhombic-ovoid, apex acuminate into subulate, with 5-7 veins, usually rusty when dry, stellate tomentose, bracteoles inconspicuous; Flowers with short peduncle, blue, densely covered with gray, branched or unbranched villi. Calyx egg

temperature

Lavender is very adaptable. The adult plant is resistant to both low temperature and high temperature, and can withstand high temperature of about 40℃ in harvest season. Huanglong area, Shaanxi,

Lavender garden photos (9 photos)

An aromatic herb.

Clover plants overwinter safely in the open field at-265438 0℃; In Xinjiang, it is buried in the soil and covered with snow, which can withstand the low temperature of -37℃. The seedlings can tolerate the low temperature of-10℃. During the growth and development of lavender in the second year, the average temperature is in

At about 8℃, the germination needs10 ~15d; The average temperature is 12~ 15℃, which takes 20 days for plant branches to turn green and grow longer. The average temperature is 16~ 18℃, and it takes 25 ~ 30 days to start budding. average temperature

Flowering begins at 20~22℃; The average temperature is 26~32℃, which is the fruiting period. [3]

moisture

Lavender is a plant that likes to be dry and needs less water, with an annual rainfall of 600 ~ 800 mm During the green turning period and budding period, plants grow faster and need more water. The water requirement at flowering stage is low; The amount of water should be appropriate during the fruiting period; Winter dormancy should be irrigated or covered with snow in winter. Therefore, the ideal rainfall distribution in a year is more in spring, moderate in summer and more in winter. [3]

sunlight

Lavender is a kind of long-day plant, which needs sufficient sunshine during its growth and development, and the annual sunshine hours are required to be above 2000h h. If a plant is in a humid environment, it will develop poorly and age faster. [3]

land

Lavender has a well-developed root system, and likes deep, loose, breathable fertile soil rich in silicon and calcium. Soil with strong acidity or alkalinity and plots with high viscosity, poor drainage or high groundwater level are not suitable for planting. [3]

3 geographical distribution editing

Foreign distribution

Lavender was originally wild in southern France and the southern foothills of the Alps along the Mediterranean coast of Italy.

along with

And Spain, North Africa and other places. In13rd century, it was the main plant in the gardens of European medical monasteries. 15th century, planted in Haier Xia District. /kloc-at the end of 0/6, farming began in southern France; 18 generation

In 2000, Mickey in Surrey, Smoked Mountain in South London, Provence in France and the mountainous areas near Grasse were all famous for planting lavender and became world-famous tourist attractions. 19th century, Britain, Australia, America, Hungary, Bulgaria,

Russia, Japan and other countries have introduced and cultivated them one after another, and now they have spread all over the Mediterranean and Black Sea countries. [3]

Domestic distribution

After thousands of years 10 years of careful cultivation in Yili, Xinjiang, lavender has formed a scale on the Ili River at the foot of Tianshan Mountain. Lavender is a precious and important natural perfume plant, and its fragrance is refreshing, rich and pleasant. Ili Kazak Autonomous Prefecture in the hinterland of Tianshan Mountain is the main base of lavender cultivation and processing in China, and also the largest spice production base in Asia. [3]

Breeding mode

sexual reproduction

Lavender is in full bloom from May to 10 every year.

Seeding and seedling raising, rapid propagation, developed roots, Miao Zhuang, is a good material for seed selection. The seeds should be uniform in size, full and brown in luster. Before sowing, the seeds should be dried, soaked in warm water at 30℃ 12~24h, soaked in concentrated sulfuric acid for 5min, washed with water, dried and then sown. It can be sown and propagated in April. The lowest temperature of seed germination is 8 ~ 65438 02℃, and the optimum temperature is 20 ~ 25℃. It can be planted in May, but the seeds of lavender have great reproductive variation and high seed price. [4]

asexual reproduction

Lavender is propagated mainly by cutting, which can maintain the excellent quality of the female parent. Cutting has strong adaptability and can be carried out in spring and autumn. Generally, healthy plant terminal buds (about 5 ~ 10 cm) or lignified shoots are selected for cutting. When cutting, remove the leaves from the bottom two nodes, and then soak them with rooting agent 100 times. After treatment, they will take root in the soil for about 2 ~ 3 weeks. The cutting substrate can be evenly mixed with river sand and oval chaff according to the ratio of 2∶ 1, and put into a 5× 10 plug for cutting. After planting seedlings, put them in a ventilated and cool environment, keep the soil moist for the first three days, and then ensure that the branches are not wrinkled and dry according to the weather conditions to improve the survival rate. Cutting seedlings are easy to manage and do not need fertilization during the whole seedling stage, so they are widely used in production. [5]

Tiantuan management

Pruning and pruning

The new species of lavender grows slowly in the early stage. With the temperature rising in spring, lavender entered the green stage in mid-April, which increased the score for the promotion of lavender.

Beautiful lavender

For the development of branches and roots, artificial pruning should be carried out from the end of April to the beginning of May, that is, the top branches above the ground 15cm should be trimmed flat, the middle part of the plant should be pruned again, and the periphery should be lightly trimmed. [6]

Bud emergence and flowering management

In the local area, the 1 crop lavender entered the budding stage in late May and the blooming stage in late June. In the planting year of 1, in order to promote the branch growth of lavender seedlings and reduce nutrient consumption, 1 bud can be knocked out in early June. The second crop of flowers enters bud stage in mid-August and blooms in mid-September. In the case of good weather conditions in autumn, the third crop of flowers bloomed in mid-June at 65438+ 10. [6]

Irrigation and intertillage weeding

For newly planted lavender, sufficient irrigation should be ensured in the first three years to promote plant growth. Every year in the middle and late April, lavender should be watered in time during the greening period. Water it 6-8 times a year according to the weather and soil moisture. Pay attention to the key watering of bud water and flowering water, and water should be poured evenly and thoroughly to ensure the watering quality. Combined with timely intertillage for each irrigation, the purpose of moisture conservation, temperature increase and weeding is achieved, and intertillage weeding is generally carried out for 5~7 times throughout the year. 165438+1winter water irrigation in the first half of October. [6]

Superficial application

Although lavender has strong barren and drought tolerance, it needs to provide relatively more water and fertilizer to promote its rapid growth and increase its yield after planting. Duixin

Lavender should be fertilized early and frequently within 3 years after planting. Combined with 1 fertilization, 1 budding stage of crops, combined with watering mu, urea 15kg, diammonium phosphate10 kg; Be applied; The second topdressing of urea per mu

10kg, artificial point application beside plants. [6]

Management before overwintering

Winter is long and the temperature is low. Field experiments show that in order to ensure the safe wintering of lavender in this area, artificial mulching must be carried out before wintering. That is 1 1 month.

After watering the wintering water in the early stage, the branches of lavender above the ground 15~20cm should be pruned, and then surrounded by soil, and the buried soil thickness is about 15cm, so as to ensure that the base of the tree will not suffer from freezing injury. Note that the buried soil should not be too thick or too thin. In the next spring, before watering the green water, the soil should be scraped off in time to release the seedlings, that is, the soil covering the plants should be scraped off to prevent the branches and leaves from rotting in the soil. [6]

harvest

The suitable harvesting time is the full flowering period, that is, when 70% of the florets in the ear are in bloom, harvesting too early or too late will affect the yield. The first flowers are usually from late June to mid-July.

Two-crop flowers in ten days1late September to1early October. Forecast yield before harvest. Weeds and excessive stems and leaves should not be entrained during harvesting, so as not to affect the quality of oil. Sunny days after 10: 00, such as morning dew, should be selected after harvesting.

It is not suitable for harvesting in big days or cloudy days. The stronger the light, the hotter the day, and the higher the oil yield. When transporting and drying flowers, they should not be piled too thick to prevent fever and self-steaming, and must be treated on the day of harvesting. [6]

disease

Control of leaf spot;

When the annual sowing seedlings or cuttings are damaged, the plants wilt, lose water, the leaves are dull, and the top of leaves and branches bend downward and droop.

The performance of the period is the most obvious. Light can recover at night, and heavy will die in two or three days, with rotten roots and brown shiny stems. In addition to pathological manifestations, seedlings over three years old have wilting symptoms at the center or edge of the plant, which gradually develop inward and outward, and the branches wilt and die, and finally the whole plant dies. Generally, it starts in May and reaches its peak in July and August. Spray bordeaux solution 1∶200 2 ~ 3 times or zineb solution 500~800 times. Root rot and Fusarium wilt: 500-fold solution of 50% carbendazim or 400-fold solution of 50% thiophanate-methyl is used for root irrigation or foliar spraying. [3]

control of insect

Starscream: diluted 600~ 1000 times with 1.8% avermectin, or sprayed with dicofol.

Cicada and flea beetle: control with pyrethroids, such as 50% phoxim EC, 50% cartap EC and 12% pesticide. [3]

Waiting for Love, just like the TV series Lavender, lavender means an implicit show of love, a firm commitment, and finally you can hold your child's hand after suffering. [9]

One legend is that ...

Lavender is a fragrant purple-blue flower. It's as romantic as its location. This flower grows in Provence, France,

There is a beautiful love legend. [ 10]

In Provence, France, one of the hometown of lavender, there is a love story about lavender. ...

It is said that there is a girl in the village of Provence. She was alone in the cold mountain picking budding flowers, but she met an injured traveler from far away. When the girl saw the young man, her whole heart was captured by his elegant smile! [ 10]

So the girl invited him home, regardless of family opposition, and insisted on taking care of him until he recovered. After a few days, the traveler's injury has healed, but their love affair has spread rapidly and has reached the point of inseparable. [ 10]

One day soon, the young traveler said goodbye to the girl, but the girl who was in love insisted on leaving with the youth. Although her relatives tried their best to keep her, she still insisted on going to her hometown full of roses with her youth! [ 10]

Just before the girl left, the old lady in the village gave her a bunch of lavender to test the sincerity of young travelers, because it is said that the fragrance of lavender can make unclean things appear.

Just as the traveler was holding her hand and preparing for a long trip, the girl threw lavender hidden in her coat on the young man. Unexpectedly, the young man's body gave off a purple light smoke and disappeared with the wind! And the girl in the valley seems to vaguely hear the young people's hearty laughter. In this way, the girl was left alone. [ 10]

Some people say that she followed the scent of lavender to find youth ... Anyway, the legend of lavender has been handed down. So until now, lavender is still regarded as one of the important tools to drive away unclean things and incense. [ 10]
