苗木主要分為喬木、灌木、地被以及草坪等，喬木是指樹身高大的樹木，由根部發生獨立的主干，樹干和樹冠有明顯區分。有一個直立主干、且高達6米以上的木本植物稱為喬木。與低矮的灌木相對應，通常見到的高大樹木都是喬木，如木棉、松樹、玉蘭、白樺等。喬木按冬季或旱季落葉與否又分為落葉喬木和常綠喬木。 喬木主要從它的花、葉、枝條、形狀等幾個方面來區分，質量主要是看它的葉子是否鮮亮，樹形如何，有沒有傷枝、斷枝、病蟲害枝、土球的大小是否合理，土球的土壤是否新鮮、潮濕，是否是人工造的假土球等立面來判斷。 　　灌木是沒有明顯主干的木本植物，植株一般比較矮小，不會超過6米，從近地面的地方就開始叢生出橫生的枝干。都是多年生。一般為闊葉植物，也有一些針葉植物是灌木，如刺柏。如果越冬時地面部分枯死，但根部仍然存活，第二年繼續萌生新枝，則稱為“半灌木”。如一些蒿類植物，也是多年生木本植物，但冬季枯死。有的耐陰灌木可以生長在喬木下面，有的地區由于各種氣候條件影響（如多風、干旱等），灌木是地面植被的主體，形成灌木林。沿海的紅樹林也是一種灌木林。 灌木主要從高度、冠幅、葉片色澤、、病蟲害、土球、產地等方面來判斷。 Seedlings were mainly divided into trees, shrubs, and grass, tree refers to the tree tall trees, by the roots occur independent of the trunk, trunk and canopy has obvious distinguish. Have a straight trunk, and up to 6 meters of woody plants, called a tree. Correspond to low shrubs, usually see the tall trees are trees, such as kapok, pine, yulan, birch, etc. Is divided into tree leaves in winter, or dry season or not deciduous trees and evergreen trees. Tree mainly from its flowers, leaves, branches, to distinguish between several aspects, such as shape, the quality is mainly to see if it leaves bright, the tree, have hurt branches, production, plant diseases and insect pests, soil ball is reasonable, the size of the soil is fresh, moist soil ball, ball is made of artificial false soil such as facade to judge. Bush was no obvious backbone of woody plants, plant is compared commonly small, no more than 6 meters, out of the place close to the ground began to cluster horizontal branches. Are perennial. Generally for broadleaf plants, there are also some conifers are shrubs, such as juniper. If winter when the ground part of the dead, but the root is still alive, in the second year continue to initiation sections, it is called a "subshrub". As some artemisia plants and perennial woody plants, but die in winter. Resistance to some dark bushes can grow under the tree, some areas because of the influence of various conditions (e.g., windy, drought, etc.), shrub is the main part of the ground vegetation, the formation of bushes. Coastal mangrove forest is also a kind of shrub. Shrubs mainly from height, crown breadth, leaf color,, plant diseases and insect pests, soil ball, origin, etc. 返首頁：www.sorensendy.com
