绒毛白蜡(Fraxinas velutiwa),又叫津白蜡,以速生、形美、材优而著称,还由于它具有耐盐碱、抗水湿、抗有害气体和抗病虫害较强的特点,被天津市列为主要绿化造林树种之一。连云港市地处黄海之滨,土壤盐碱,质地粘重,给绿化带来了一定的困难,连海路东段曾多次植树,均遭失败,自1976年引种天津白蜡,成效显著。但是,由于种子来源困难,种子育苗远远不能满足绿化需要。为此,我所于1980-1981年进行了白蜡扦插育苗试验。两年来,春、夏、冬三季圃地扦插和大田扦插,均取得了比较好的效果。春插白蜡保存率达86%,平均高1.5米,根径1.4厘米,生长最好的高达2.58米,根径2.4厘米。年生长量优于定植、截干苗,更为播种苗所不及。 Fraxinas velutiwa, also known as Jinbai Wax, is famous for its quick-growing, beautiful shape and excellent material. It is also widely used in Tianjin column because of its characteristics of resistance to salt, water, humidity and harmful gases and pests and diseases. As one of the main afforestation tree species. Lianyungang City is located in the Yellow Sea coast, soil salinity, sticky texture, to the afforestation has brought some difficulties, even the eastern section of the sea had repeatedly tree planting, have failed, since 1976, the introduction of Tianjin white wax, with remarkable results. However, due to the difficulty of seed sources, seedling nursery far can not meet the greening needs. To this end, I conducted in 1980-1981 cuttings of white wax cutting test. Two years, spring, summer and winter garden cuttings and field cutting, have achieved good results. Spring inserted white wax preservation rate of 86%, an average of 1.5 meters high, root diameter of 1.4 cm, the best growth of up to 2.58 meters, a root diameter of 2.4 cm. Annual growth is better than colonization, truncated stems, more sowing less.
