在塞外宣化,江南槐以其花序大、花期长、颜色艳丽等特点,成为几年来园林绿化中大量使用的新优树种。但它有一个致命的缺点,就是不论几年生的苗(有些已达5～6厘米粗),到了生长旺季(7～8月)遇到大风,总会有15～20％的植株被刮断。江南槐大多是在胸径3～5厘米的洋槐上高位(高1.8～2.0米处)枝接繁殖的,风折的部位大多数在接口处,有的一半树冠被刮掉,有的整个被刮掉。一年生刚嫁接的苗木如不加绑缚能被风刮掉80％。在一块完美的绿地上,被刮掉树冠的江南槐象个“无头鬼”,煞是难看。
In the plug Xuanhua, Jiangnanhuai with its inflorescence, long flowering period, bright colors and other characteristics, to become a landscaping in recent years, a large number of new tree species. But it has a fatal flaw, regardless of perennial seedlings (some of which have reached 5 to 6 cm thick), to the growing season (July to August) encountered strong winds, there will always be 15 to 20% of the plants were scraped off . Jiangnanhuai mostly in the diameter of 3 to 5 cm diameter acacia on the high (1.8 to 2.0 meters high) branch reproduction, most of the wind folding parts at the interface, and some half of the canopy was scraped off, and some were scraped Off Freshly grafted annual seedlings can be scraped off by 80% if they are not bound. In a perfect green, Jiang Nanhuai was scraped off the crown like a “headless”, it is truly ugly.
