摘要
以三道川林场内的野生沙棘为试验材料,研究不同采穗时间和扦插密度对沙棘嫩枝扦插生根情况的影响。结果表明,不同处理对沙棘嫩枝生根率、平均根数、平均根长的影响均较大,插条应在早、晚采集;当扦插密度为400株/m^2～600株/m^2时,生根率达到94%以上,而且根系生长状况良好,有利于移植后生长。
Effect of collection time and cutting density on rooting situation of Hippophae rhamnoides twigs cuttings was studied with wild Hippophae rhamnoides from Sandaochuan farm as test material. Results showed that the effect of different treatment on rooting rate,average root number and average root length of Hippophae rhamnoides twigs was great. Cuttings should be collected in the morning or evening. The treatment which cutting density at 400 plants/m^2~ 600 plants/m^2 was conducive to the growth after transplantation. Its rooting rate was higher than 94%,and the growth situation of roots was better.
