摘　　要：通过比较不同移栽时间连翘幼苗成活率和不同定植密度连翘青翘鲜果的产量,得出适合陇西县连翘移栽的最佳时间为春季3月中旬—4月中旬,移栽平均成活率可达95%以上,连翘定植幼树期(3~6年)应选择株距为1.5 m,行距为2.0 m,密度为222株/667 m^(2),进入盛果期(7~8年)后需要减小定植密度,将连翘株距变为2.0 m,行距变为3.0 m,密度变为111株/667 m^(2),即可保证连翘的丰产和稳产。By comparing the survival rate of Forsythia suspensa seedlings at different transplanting times and the yield of Forsythia suspensa green fruits at different planting densities,it was concluded that the best transplanting time for Forsythia suspensa in Longxi County is mid-March to mid-April in spring,and the average survival rate of transplanting could reach more than 95%.During the seedling planting period(3~6 years),the plant spacing should be 1.5 m and the row spacing should be 2.0 m.The density was 222 plants/667 m^(2),after entering the full fruit period(7~8 years),it is necessary to reduce the planting density,and Forsythia suspensa plant spacing becomes 2.0 m,the row spacing becomes 3.0 m,and the density becomes 111 plants/667 m^(2),which can ensure the high and stable yield of Forsythia suspensa.
