【摘要】 在甘肃5个生态区引种川西云杉和红皮云杉,观测幼树期保存率和越冬枯枝率、生长、针叶表型性状。结果表明,川西云杉在甘肃陇南山地、黄土高原丘陵沟壑区、祁连山区、河西走廊荒漠4个生态区可以进一步扩大引种试验规模,在中部半干旱生态区则宜谨慎;红皮云杉在甘肃陇南山地、黄土高原丘陵沟壑区、祁连山区3个生态区可以进一步扩大引种试验规模,在中部半干旱、河西走廊荒漠2个生态区则宜谨慎。更多还原

【Abstract】 Picea balfouriana and P. koraiensis were introduced in 5 ecological areas in Gansu, and the preservation rate of young trees, the rate of overwintering dead branches, growth and needle leaf phenotypic traits were observed. The results showed that Picea balfouriana could be further expanded in Longnan mountain area of Gansu, loess plateau hilly and gully area, Qilian mountain area and Hexi corridor desert area, but in the middle semi-arid ecological zone, we should be cautious. The introduction experiment scale of P. koraiensis can be further expanded in three ecological areas: Longnan mountain, loess plateau hilly and gully region and Qilian mountain region, but in the middle of the semi-arid, hexi corridor desert two ecological areas should be cautious.更多还原
