Also, according to the different requirements chain link fence that may find some parts and conditions. Enterprise can be classified structure characteristics and things fence combination classification. If parts under the group, part family part family points under more parts. chain Example: (bolt and nut parts and components (have) head screws) - parts (hex bolt) link According to the actual needs of enterprise, the enterprise builds a special classification structure. £» chain link fence multilayer classification structure: classification of N, the first element into layer for entry (0 root fence node). The first element of N is classified structure elements £» will things characteristics and chain classify elements combined different things, and classification of each layer classification structure combining elements. This link classification structure element + things. = elements. Such as the classification and characteristics of element chain link fence 1 together constitute a classification.A file name, the gold gold of rutaceae family, a file. fence Habits: origin and file in warm southern areas. Sex is like cool, moist and drought, chain cold resistant to cloudy. Deep fertile soil, the requirement of soil acidic. A file of link morphological characteristics: evergreen shrubs or small trees.

A small fruit, obovate, 3 centimeters, it is yellow, the juice taste chain can even skin. ShiShengMiao sow breeding technology: file, more variety offspring, general deterioration, using the link seed propagation. Common grafting. Gold content in root orange and lime, can improve fight cold chain link fence ability, generally USES YaJie and branches.
