健杨于五十年代从欧洲引进我国,目前辽宁、河北、山东等省均有栽培.我省徐淮地区有零星栽植.木材较好,原木可作矿柱材,民用建筑材,又是优良的纤维工业、火柴工业、造纸工业及胶合板工业原料,也可作家具和箱板用材,是有利用价值的优良速生用材树种.但该树种在滨海盐碱土上生长适应性和耐盐程度如何?尚缺乏资料.为此我们从1981—1982年对健杨进行了苗木耐盐试验,现初报如下:试验地自然概况试验地设在江苏射阳沿海防风林试验站内的滨海盐碱地上.地处亚热带北缘,年平均气温13.7℃,最高气温35.8℃,最低气温
Jian Yang was introduced into our country from Europe in the 1950s, and is now cultivated in Liaoning, Hebei and Shandong provinces. There are sporadic planting in Xuhuai area in our province. The wood is good and the logs can be used as pillars and civil building materials, which is also excellent The fiber industry, matchmaking industry, paper industry and plywood industry raw materials, but also for furniture and board materials, is the use of excellent fast-growing timber species .But the species in coastal saline-alkali soil growth adaptability and salt tolerance? There is no data.For this purpose, we carried out salt tolerance test of Jian Yang from 1981 to 1982. The preliminary reports are as follows: The natural conditions of the experimental site are located on the coastal saline soil in the coastal windbreak test station of Sheyang, Jiangsu Province, North margin, the annual average temperature of 13.7 ℃, the highest temperature of 35.8 ℃, the lowest temperature
