从气候、土壤、病害等方面具有相似性的自然生态分布区去选择引种对象,是目前把握最大且最经济有效的一种种植途径。太行山,北起京西山山簏,南害豫北黄河岸边,纵贯华北平原西侧,绵延400余公里。山麓植物种类繁多,距离华北的各大城市又都不远,其气候、土壤、纬度等自然条件也相对近似,因此,这里堪称华北地区城市园林观赏植物的基因宝库。每年的暮春的夏秋交季,山花烂漫,百果飘香,在这两个时节上山,能观察到很多种具有观赏价值的野生植物并有可能找到非常具有引种前途的对象。比如胡颓
From the climate, soil, disease and other similar areas of natural ecological distribution to select the introduction of the object, is to grasp the largest and most economical and effective way of planting. Taihang Mountains, north from the Beijing Western Hills Shanxu, south of the Yellow River in northern Henan coast, north-west of the plain, stretching more than 400 kilometers. The foothills of a wide range of plants from the major cities in North China are not far, its climate, soil, latitude and other natural conditions are relatively similar, so here is called the North China city ornamental plant genetic treasure house. The annual summer and fall seasons, blooming Yamahana, hundred fruit fragrance, in these two seasons up the mountain, you can observe a variety of ornamental value of the wild plants and may find a very promising introduction of the object. Such as decadent
