悬铃木(又名法国梧桐、英国梧桐),树形优美,发枝力强,树冠遮荫面积大,吸尘能力强,抗污染,为城镇、厂矿、学校的良好的绿化树种。目前,汉中地区多用1年生苗进行扦插繁殖,但因种苗缺乏,使发展受到限制。为解决这个问题,1981年我圃以壮龄悬铃木1年生枝为插条,进行了扦插育苗试验,成活率78%。1982年春在此基础上继续进行试验,成活率进一步提高到87.5%。现将两年来试验结果整理于后。一、试验材料1.插条:取自西乡县板桥公社公路两旁,1964年栽植的5株大树的1年生枝条以及我圃1年生扦插苗。插穗剪留标准为3节4芽,上切口平剪,下切口斜剪。2.试验地:试验设在苗圃地。圃地为砂壤土,排水良好,较脊薄,微碱性,土层深
Platanus (also known as Platanus, Indus), tree-shaped, strong branches, tree shade area, dust-absorbing ability, pollution-resistant, for the towns, factories, mines and schools of good afforestation species. At present, the use of 1-year-old seedlings in Hanzhong area for cutting propagation, but due to the lack of seedlings, so that development is limited. In order to solve this problem, in 1981, I nursery stands with annual branch of Platanus chinensis as cuttings, cuttage nursery test, the survival rate of 78%. Spring 1982, on the basis of this trial, the survival rate was further increased to 87.5%. Now two years after finishing the test results. First, the test material 1 cuttings: taken from the Xixiang County Banqiao commune roads, planted in 1964 5 trees and 1 year-old branches I nursery cuttings. Cuttings cuttings for the three sections of 4 buds, on the cut flat cut, incision under the shear. 2. Test place: The test is located in the nursery. Garden for sandy loam, drainage well, more ridges, slightly alkaline, deep soil
