(3) Adopting electric heating line to raise seedlings, control the temperature of the seedbed at about 16 °C, generally not lower than 12 °C, so that the seedlings grow vigorously.
(4) After a slight rooting, it is necessary to loosen the soil in time and raise the ground temperature. After the new root grows, it will be transferred to normal management.

Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important.
