继1979年引种推广意大利杨树以后,1981年在中国林科院支持下,淮阴市先后在八个县开始了西马杨、鲁易莎杨苗木繁育和小片林栽植试验。到1986年底,共营造试验林、丰产林716亩。经过对比试验,现已取得初步结果。5年生平均树高为17.8米,胸径26.7厘米,单株材积0.37立方米,显著超过了江苏省农林厅规定的丰产林标准,与目前推广的意大利杨比较,超过214杨、接近69杨,略低于72杨,63杨。 8月26日,江苏省农林厅邀请了中国林科院,南京林业大学,江苏、山东省林科所和淮阴市科委以及市、县林业部门的专家、教授在泗阳召开了品种试验鉴定会。通过讨论,分析试验数据和现场考察,代表们一致认为,西马、鲁易莎两个杨树新品种在淮阴引种是成功的,除具有意大利杨速生丰产的优良性状外,更具与抗寒、抗旱、抗杨树褐斑病较强的特点,且栽培容易,成活率高,便于推广,完全适合淮阴地 Following the introduction and popularization of poplar in Italy in 1979, with the support of the Chinese Academy of Forestry in 1981, Huaiyin City started the breeding of small seedlings of Simao and Luisa Poplar in eight counties. By the end of 1986, a total of 716 acres of experimental forest and high yield forest will be built. After a comparative test, preliminary results have been obtained. The 5-year-old average tree height is 17.8 meters, diameter at breast height 26.7 centimeters, single plant volume 0.37 cubic meters, significantly exceeding the standards of high yield forest specified by the Department of Agriculture and Forestry in Jiangsu Province, compared with the current poplar Poplar, more than 214 Yang, close to 69 Yang Below 72 Yang, 63 Yang. August 26, Jiangsu Provincial Department of Agriculture and Forestry invited Chinese Academy of Forestry, Nanjing Forestry University, Jiangsu, Shandong Province Forestry Branch and the Science and Technology Commission of Huaiyin City, as well as municipal and county forestry experts and professors held a variety of test identification in Siyang meeting. Through discussing and analyzing the test data and field investigation, the delegates agreed that the introduction of two new poplar varieties, West Malaysia and Luyesha, was successful in Huaiyin. In addition to the good traits of fast growing and high yielding in Italy, , Strong resistance to poplar leaf spot characteristics, and easy cultivation, high survival rate, easy to promote, fully suitable for Huaiyin
