The producing environment of lavender

1. Temperature: lavender has strong adaptability, adult plants can withstand both low temperature and high temperature, and can withstand high temperature of about 40 ℃ in harvest season. Huanglong area of Shaanxi Province can safely winter in-21 ℃. * * area can withstand low temperature of-37 ℃ by burying soil and snow cover, and seedlings can withstand low temperature of-10 ℃. In the process of growth and development in the following year, the average temperature is about 8 ℃, the average temperature is 10: 15 days, the average temperature is 12: 15 ℃, the average temperature is 20 days, the average temperature is 16: 18 ℃, the average temperature is 25: 30 days, the average temperature is 20: 22 ℃, and the average temperature is 26: 32 ℃, which is the fruiting stage.

2. Moisture: lavender likes drying and does not need much water, and the annual rainfall is 600-800mm. In the green and budding stage, the plant grows faster, requires more water, needs less water in the flowering stage, and is suitable in the fruiting stage. Winter dormancy should be winter irrigation or snow cover, the ideal distribution of rainfall in a year is abundant in spring, moderate in summer, and plenty of snow in winter.

3. Sunshine: lavender is a long sunshine plant, the growth and development period requires sufficient sunshine, and the annual sunshine hours are more than 2000 hours. if the plant is in a damp environment, it will underdevelop and age quickly.

4. Soil: lavender has developed root system, fertile soil with deep, loose, good air permeability and rich in silicon and calcium, strong acidic or alkaline soil and land with heavy viscosity, poor drainage or high groundwater level, are not suitable to grow.
