青海云杉(Picea crassifolia Kon)是我国特有树种,原产祁连山、青海、甘肃和宁夏等地。以青海最广,一般分布在海拔1600—3800米之间,是常绿乔木,木材用途广泛,材质优良,是抗旱性较强的树种。 1976年我们从青海引入吉林地区,通过6年来的栽培试验,苗木及幼树生长普遍良好,现将情况整理如下: 一、试验地的自然概况 1976年在磐石苗圃进行育苗,3年生苗移在大旺林场及仙人洞山。本地处于温带,7月平均气温22.2℃;最高气温36.1℃,2月平均最低气温—19℃,无霜期124.8天;年降水
Picea crassifolia Kon is endemic to China, native to the Qilian Mountains, Qinghai, Gansu and Ningxia. The most widely in Qinghai, generally distributed in the 1600 - 3800 meters above sea level, is evergreen trees, timber widely used, good material, is a drought-resistant tree species. In 1976, we introduced from Jilin Province into Qinghai Province. After six years of cultivation experiments, the growth of seedlings and saplings was generally good. Now the situation is summarized as follows: I. Natural Overview of the Experimental Site Nurture seedlings at Panshi Nursery in 1976, Large forest floor and immortal cave. The local temperature is in July, the average temperature of 22.2 ℃; the highest temperature of 36.1 ℃, the average minimum temperature in February -19 ℃, frost-free period of 124.8 days; annual precipitation
