赤峰市郊区林业研究所承担并与当铺地苗圃协作的研究项目“胡杨引种育苗技术的研究”,经过两年的努力,已取得阶段性的成果,并于1986年9月通过了技术鉴定。胡杨是盐碱地的主要造林树种,赤峰市有盐碱地300多万亩,五十年代开始引种胡杨,但一直没有成功。赤峰市郊区林研所从1985年春开始搞胡杨引种试验,通过两年三次的播种试验,胡杨苗生长良好,发育健壮。其中,二年生胡杨苗540平方米,产苗23,000株,平均苗高86.6厘米,平均地径0.63厘米;最高苗达160厘米,地径1.2厘米,准备翌春出圃,进行造林试验。
After two years of hard work, the research project “Populus euphratica Introduction Seedling Raising” undertaken by the research institute of suburban forestry in Chifeng City and cooperated with the pawnbroker nursery school has achieved staged achievements and passed the technical appraisal in September 1986. Populus euphratica is the main afforestation tree species in saline land. There are more than 3 million mu of saline land in Chifeng City. Populus euphratica was introduced in the 1950s but it has never been successful. Forest Research Institute in the suburbs of Chifeng from the spring of 1985 began to engage in introduction of Populus euphratica, through two years three sowing experiments, Populus seedlings grow well, robust development. Among them, the biennial Populus euphratica 540 square meters, seedlings 23,000, the average height of 86.6 cm, an average diameter of 0.63 cm; the highest seedling of 160 cm, diameter 1.2 cm, ready for next spring Chu nursery, afforestation test.
