为选育适于宁夏栽培的优良杨树新品种，以银白杨（Ｐｏｐｕｌｕｓａｌｂａ）为母本、河北杨（Ｐ．ｈｏｐｅｉｅｎｓｉｓＨｕｅｔｃｈｏｕ）为父本，进行人工杂交育种。经过Ｆ１杂种筛选、测定，选育出银河１号、银河２号２个优良品种，其５年生材积分别超过对照银新２号杨５７．７％和２６．１％；材性指标超过银新杨；抗天牛率为９１．７％～９４．５％，超过银新杨６３．５％、新疆杨６９．８％、银白杨７９．２％。 In order to breed new good poplar cultivars suitable for cultivation in Ningxia, Populus alba was used as female parent and P.hopeiensisHuetchou as male parent for artificial breeding. After screening F1 hybrids, two excellent cultivars, Yinhe 1 and Yinhe 2, were selected and their 5-year product yields were 57.7% and 26.1% higher than that of Yinxin 2 Yang respectively. Yang; anti-terrestrial cattle rate was 91.7% ~ 94.5%, exceeding 63.5% of silver new yang, Xinjiang Yang 69.8%, silver poplar 79.2%.
