During this period of time, the oil yield per unit rose weight is the highest, basically stable at more than 3 / 10,000; others The oil content is significantly reduced when picked during the time period, generally 20-30% lower than that picked in the early morning, or even more. Especially after direct sunlight, the essential oil in the flower will be partially volatilized due to high temperature.
[0078] 2. The quality of flowers requires that the flower center has just opened, the petals should be pink in color, and the flower shape should be cup-shaped. At this time, the harvest is...
