Questions about the cultivation of lavender, conditions for the cultivation of lavender

I don't understand, you bought a pot of seedlings? Or seeds?

If you sow seeds, you can choose to broadcast live, that is, directly bury in the soil. You can also soak the seeds first, with water at thirty or forty degrees, that is, water that does not burn your fingers, and soak it for no more than 24 hours. The soil is watered thoroughly at one time, and then the seeds are placed on the surface of the soil, lightly pressed with your fingers, and covered with a relatively light medium, about one centimeter, that is, 1-2 times the volume of the seeds.

Then cover with a layer of film, prick a few holes to breathe, and put it in a sunny place, and keep the soil moist all the time. After the seedlings emerge, you can remove the film and bask in the sun. Don't put it in a place where the temperature is too high in summer, and when watering in winter, you can see dry and wet, that is, when the soil is dry, you can water it thoroughly.

After soaking, you can also choose to sprout first and then plant. Find a flat container, plate or the like, spread a paper towel, makeup cotton, or a small towel, spray it with water, and then put the soaked seeds on it, cover it with a layer of paper towels, spray it wet, put it in a plastic bag, tie a few holes to breathe, put it in a warm place with sunlight, open the mouth to ventilate for about an hour every day, observe the seeds at any time, find that the white is exposed, and immediately plant in the soil, the white part is the root, not the bud, don't plant it back. Slow down the seedlings in the shade first, and then slowly see the sun.

In addition, the germination rate is low, and you can rub the seed coat with a towel to remove the oil from it before sowing and soaking the seeds.

1. Temperature.

Lavender is highly adaptable. Adult plants are resistant to both low and high temperatures, and can tolerate high temperatures of about 40 during the harvest season. In the Huanglong area of Shaanxi Province, lavender plants safely overwintered in the open at -21; In Xinjiang, it can withstand -37 low temperatures after buried soil treatment and snow cover.

Seedlings can tolerate low temperatures of -10.

2. Flowering period. During the growth and development of lavender in the following year, the average temperature was about 8, and it took 10 15 days to germinate. The average temperature was 12 15 days, and it took 20 days for the branches to regreen and elongate. The average temperature is 16 18 days, and it takes 25 30 days to bud on. The average temperature is 20-22 and flowering begins; The average temperature is 26 32 and is the fruiting period.

3. Moisture. Lavender is a dry-loving plant that does not require much water, and the annual rainfall of 600 800 mm is more suitable. At the rejuvenation stage and budding stage, the plant grows faster and requires more water. Low water requirement during flowering; The amount of water should be appropriate during the fruiting period; During the winter dormant period, winter irrigation or snow cover is required. Therefore, the ideal distribution of rainfall in a year is abundant in spring, moderate in summer, and plenty of snow in winter.

4. Sunshine. Lavender is a long-day plant, which requires sufficient sunshine during the growth and development period, and more than 2000 hours of sunshine throughout the year. If the plant is in a humid environment, it will develop poorly and senescent rapidly.

5. Soil. Lavender has a well-developed root system and prefers deep, loose, well-ventilated and silica-rich fertile soil. Acidic or alkaline soils and plots with heavy clays, poor drainage or high water tables are not suitable for planting.

Yinda Irrigation District is located in the northwest of Lanzhou City and the east of Yongdeng County. It mainly includes four towns, Shangchuan, Qinchuan, Zhongchuan and Shuping, with a total land area of about 2,000 square kilometers, which is a relatively flat area of Lanzhou City, with a total population of about 160,000 people and a cultivated land area of about 900,000 mu. The elevation of the irrigation area is between 1700 and 2300 meters, surrounded by loess covered loess beams and river valley plains, stony middle and low mountains and intermountain basins, the terrain is flat and open, and the land is concentrated and contiguous, which is suitable for agricultural development.

The irrigation area belongs to the temperate arid zone in the northern part of Longzhong, with obvious continental climate, drought and little rain, large temperature difference between day and night, and clear cold and warm. The solar and thermal resources are abundant, with 2660-2768 hours of sunshine in the whole year, and more than 9 hours of sunshine in summer. The average annual temperature is 125-175 days without frost.

The active accumulated temperature of 0 is 2893, and the active accumulated temperature of 10 is in between. The average annual precipitation is 285mm, mostly concentrated in three months, the annual evaporation is 1950mm, the main irrigation water source depends on the diversion project, and the annual irrigation is guaranteed to irrigate three waters. According to the characteristics of lavender that is easy to cultivate, like sunlight, heat-resistant, drought-resistant, extremely cold-resistant, barren-tolerant, salt-alkali resistant, and the cultivation site needs sufficient sunshine and good ventilation, the natural conditions of the world's main producing areas have been collected and compared, and the large irrigation area is completely suitable for planting lavender.

If it's a seed, it's best to be in spring, lavender is perennial, there is no problem in 10 years, and it can be cuttings, and it will freeze to death if it is too cold in winter.
