1. Judging by the structure of the trees and the growth characteristics of the branches. However, some seedlings are not dead. Like sweet-scented osmanthus, big, the trunk is obviously arbor, but some small osmanthus, I used to be hedge, which should be regarded as a shrub.
2, generally more than three meters can be called trees, but in reality there is no clear boundaries, to experience from the experience of life!
3, arboreal tall (usually 6 meters to tens of meters), with a clear tall trunk. According to its height, Wei Qiao (31 meters or more), Da Qiao (21-30 meters), Zhong Qiao (11-20 meters), Xiao Qiao (6-10 meters), etc. Dwarf (usually less than 6 meters), the main trunk is low.
4. Classification in the form of plant stems Woody plants with an upright stem and up to 5 meters in height are called trees. Corresponding to low shrubs, the tall trees that are usually seen are trees, such as kapok, pine, magnolia, birch and so on. The deciduous trees are divided into deciduous trees and evergreen trees in winter or in the dry season.
The main trunk of shrubs is not obvious, and woody plants that often emit multiple branches at the base are called shrubs, such as roses, dragon boat flowers, azalea, and peony.
Subshrubs are dwarf shrubs that are perennial, with the upper grassy stems wilting after flowering, while the stems of the base are woody, such as periwinkle and cassia.
Herbs, the stem contains less wood cells, the whole plant or aboveground parts are easy to wilt or die, such as chrysanthemum, lily, impatiens and so on. It is divided into annual, biennial and perennial herbs.

Firstly, fresh and mature fruits with good quality were selected in the pre-treatment area of the food lyophilizer, and the leaves were removed to remove impurities. Then, preliminary cleaning and simultaneous sterilization of fruit surface were carried out. After sterilization, the fruits were cleaned and drained again. After the drain, the fruit is sliced and treated by blanching process. After the color preservation, the fruit is treated by pulping, and then pasteurized. The pretreatment process is finished before lyophilization.
The processing core of freeze-drying powder is the equipment area of food freeze-drying machine. After pre-treatment, the fruit enters the equipment of food freeze-drying machine and crystallizes into a solid state at low temperature, and then sublimates and dries in a vacuum environment to obtain freeze-drying products with little water content. Freeze-dried products out of the warehouse into the food freeze-dried post-processing area, ultrafine grinding, and then according to the need to do weighing packaging, after testing the finished products packed into storage.
