我区地域辽阔,又有适应杨、柳、榆生长的自然条件,尤其是西部地区,是个缺林少树,自然灾害发生频繁的地方。杨树、柳树、榆树不仅种类少,而且生长缓慢或干形弯曲,从外地引进的一些杨、柳、榆树虽速生、干形通直,但多数又适应不了我区自然条件,往往达不到引种的预期效果。内蒙古林科院为培育速生、干形通直的优良杨、柳、榆树杂种,于一九七三年开始进行杂交育种研究工作。

My area is vast in area, and has the natural conditions to adapt to the growth of young, willow and elm, especially in the western region. It is a place with few trees and less natural disasters and frequent natural disasters. Poplar, willow, elm is not only less species, and slow growth or dry bending, some imported from the field of Yang, Liu, elm, though fast, dry straight, but most can not adapt to our natural conditions, often fail The expected effect of introduction. Inner Mongolia Academy of Forestry in order to cultivate fast-growing, stem-shaped fine Yang, Liu, elm hybrids, in 1973 began hybrid breeding research.
