摘　　要：通过对沙枣进行扦插育苗和播种育苗试验,分析了2种育苗方法的效果,结果表明:沙枣扦插育苗苗木成活率65.0%,当年平均高生长量和地径生长量分别为58 cm和0.63 cm,第2年平均高生长量和地径生长量分别为104 cm和1.08 cm。春秋季种子育苗苗木出苗率分别为75.5%和93.5%,春季育苗当年平均高生长量和地径生长量分别为38 cm和0.37 cm,第2年平均高生长量和地径生长量分别为97 cm和0.86 cm;秋季播种1年生平均高生长量和地径生长量分别为40 cm和0.38 cm,第2年平均高生长量和地径生长量分别达到95 cm和0.87 cm。沙枣播种育苗出苗率高,单位面积载苗量大,经济效益高。The effects of two seedling methods were studied through the seedling production&seeding experiments of Elaeagnus angustifolia.Result shows that the survival rate of seedling seedlings of cuttings is 65.0%&0.63 cm,the average high growth volume&ground diameter growth volume in the second year are 104 cm&1.08 cm respectively;the seedling emergence rate of seed seedlings in spring&autumn reach 75.5%&93.5%,respectively.The volume is 38 cm&0.37 cm,the average high growth volume&ground diameter growth volume in the second year are 97 cm&0.86 cm,respectively.The average high growth volume&ground diameter growth volume in the autumn seedling raising year are 40 cm&0.38 cm,respectively.The second-year average high growth&ground diameter growth reach 95 cm&0.87 cm,respectively.Elaeagnus angustifolia has a high seedling emergence rate,a large seedling load per unit area,and a high economic benefit.
