试验地设在永寿县苗圃,土壤为黄墡土。供试种条于1987年3月采自陕西省林科所延安树木园内的一年生乌柳枝条。试验分设:(1)不同长度插穗扦插试验;(2)从种条不同部位采穗试验;(3)插穗不同处理试验。每试验设3个重复,每小区30根插穗。当年全面翻土整地,深度25厘米;4月5日扦插,密度10×20厘米。扦插方法分正插、地上露0.5厘米、压实3种。插后第三天浇透水一次,以后管理同一般。6月份松地除草一次。试验结果:(1)不同长度插穗扦插试验以25厘米长的插穗成活率最高,为90.8％,其次是20厘米和15厘米,成活率分别为 Experimentally located in Yongshou County nursery, yellow soil for the soil. For the test planted in March 1987 collected from the Yanan Arboretum in Shaanxi Province Forestry Branch of the annual Wuyi branches. The test is divided into: (1) different length cuttage cutting test; (2) from different parts of the spike ear test; (3) cutting different treatments. Each experiment set up three replicates, each plot 30 cuttings. Full year of soil preparation, depth 25 cm; April 5 cutting, density 10 × 20 cm. Cuttings method is positive interpolation, the ground exposed 0.5 cm, compacted 3 kinds. The third day after pouring water once, after the management of the same. Pine weed in June once. Test results: (1) Cuttings of different length cuttings had the highest survival rate of 90.8% with 25 cm long cuttings, followed by 20 cm and 15 cm, the survival rates were
