花木资讯频道之苗木的需求与什么因素密切相关。 首先,在幼苗生态建设。主要在三北防护林体系,太行山,北京和天津的沙尘暴源控制,绿色城市,关注的绿色通道绿化隔离地区,平原造林、沙子和其他项目与彩色树种幼苗。这样的幼苗优良品种,本地树种为主,突出其保护效应和经济效应,最终实现与自然和谐的目标。
第二,城市绿化和农村绿化和美化的幼苗。城市森林建设和园林绿化建设将继续以大尺寸树和花灌木为主,尤其是彩色树种幼苗越来越多的关注,这部分树种(品种)应该突出,安全,和升值的多样性、文化内涵。
第三,经济林建设幼苗。农业种植结构的调整,速生丰产林,果树,森林和其他经济仍将继续发展,老树将会更新,品种会不断变化,因此,经济林苗会有一定的需求,尤其是经济效益和生态效益两个物种。”彩色植物有彩色造林、示范和社会。与一批的绿色科技示范项目的实施,如彩色树种在北京美化应用程序越来越多,这种树将成为市场新宠。改善人民生活水平、社会进步以及造林质量逐步提高,对幼苗质量也提出更高的要求,右边是多样性的前提下,质量是关键。抵抗强大的幼苗一直是市场的宠儿,抗旱、耐冷、耐盐性、快速增长,材料好新木材森林树种,将在一个特定的位置和防砂和速生丰产林和其他特殊项目
除了以上几种苗木,容器苗,特别是大型容器苗苗木发展趋势,因为幼苗存活率高,将主要用于反季节种植。经济林树种,特别适合种植果树品种仍有一定的市场。适用于屋顶绿化树种,因为市场需求逐步扩大也将增加。常绿阔叶树种,美丽的树树种慢生活,以及一些优秀的灌木树种将是一个很好的补充绿化项目。尤其是绿色期可以延长到12月中旬,物种会更受欢迎。基于造林率低的现状,随着造林项目的发展,通过评估应用程序将增加越来越好。

First of all, the ecological construction in seedlings. Mainly in three north shelter forest system, the taihang mountains, the Beijing and tianjin sandstorm source control, green city, focus on the green channel of the isolated afforestation region, plain afforestation, sand and other projects with color tree species seedlings. Such seedlings with fine breed, native tree species is given priority to, highlight its protection effect and economic effect, ultimately achieve the goal of harmony with nature. Second, urban afforestation and rural greening and beautification in seedlings.
Urban forest construction and garden afforestation construction will continue to give priority to with large size tree and flower shrubs, especially colorful tree species seedlings more and more attention, this part of the tree species (varieties) should be prominent, security, and the appreciation of the diversity, cultural connotations. Third, economic forest construction in seedlings. "With the adjustment of agricultural planting structure, fast-grown forest, fruit trees, and other economic forest still will continue to develop, old trees will update, varieties will be constantly changing, so the economic forest seedling will have certain requirements, especially the economic benefit and ecological benefit both species."
Colored plants with colored afforestation, demonstration, and society.with the green science and technology demonstration of a batch of the implementation of the project, such as colorful tree species in Beijing beautify the application more and more, this kind of tree will become the market to be bestowed favor on newly. Improve people's living standard, social progress, as well as the afforestation quality gradually increase, also put forward higher requirements on seedling quality, right is the premise of variety, good quality is the key. Resistance strong seedling has always been the darling of the market, drought resistance, cold resistant, salt resistance, fast growth, material good new timber forest tree species, will be in a particular location and sand prevention and fast-grown forest and other special projects
In addition to the above a few kinds of nursery stock, container seedling, especially the large size container seedlings seedlings development trend, because the survival rate is high, the seedling will be mainly used in counter-season planting. Economic forest tree species, especially suitable for planting fruit trees species still has a certain market. Suitable for roof greening tree species because of market demand to expand gradually will also increase. Evergreen broad leaved tree species, beautiful tree slow living tree species, as well as some excellent shrub tree species will be a good supplement greening projects. Especially the green period can be extended to the middle of December, species will be more popular. Based on the present situation for afforestation rate lower, along with the advancement of afforestation project, through the evaluation of good application will increase increasingly。
