沙兰杨是良好的速生用材树种,干形粗大,成材早,木材用途广泛。沙兰杨是欧美杨无性系的一个栽培品种,于1954、1959年先后自国外引进,已在我国很多地区栽植,表现良好。据辽宁、山西、河北、陕西、河南、江苏、北京等地观察,栽后性状稳定,生长迅速,唯其对水肥敏感,抗寒、抗旱性差,故中心栽培区仅为河南、陕西等地,北界地理栽培区可达到辽宁省辽河中下游平原。而在北纬42°的赤峰,年平均气温6.9℃最低气温-31.4℃的条件下,则年年受到冻害。因此,对于沙兰杨的适生范围和抗寒、抗旱性能,已引起各方面的重视。
Salmonella is a good species of fast-growing timber, dry coarse, early timber, timber uses a wide range. It is a cultivated variety of Populus euphratica in Europe and the United States. It was introduced from abroad in 1954 and 1959 and has been planted in many areas of China. According to the observation of Liaoning, Shanxi, Hebei, Shaanxi, Henan, Jiangsu and Beijing, the characters after planting were stable and rapid growth. However, only their sensitivity to water and fertilizer, cold resistance and drought resistance were poor. Geographical area of northern boundary can reach the middle and lower reaches of Liaoning Province Liaohe Plain. In the case of Chifeng 42 ° N, the annual mean temperature of 6.9 ° C and the lowest temperature of -31.4 ° C, frost damage occurs annually. Therefore, the suitable range of Salmoneilla popularis and cold hardiness and drought resistance have drawn much attention from all aspects.
