辽西地区沙棘不同方式扦插效果比较

Comparative Experiments about Different Cuttage Patterns of Hippophaerhamnoidesin Western Liaoning Province

以辽西地区主要沙棘品种辽阜1号、实优1号、中国第一代杂交种为试验材料,分别进行各品种沙棘硬枝扦插、嫩枝扦插效果的对比试验,并调查其成活率。结果表明:在相同基质、相同密度的条件下,沙棘嫩枝扦插成活率要比硬枝扦插成活率高,而在相同插穗年龄时,两种扦插方式沙棘成活率无明显差异。

Using the main varieties of Hippophae rhamnoides （Hippophae rhamnoides‘Liaofu No .1’ ,Hippophae rhamnoides‘Shiyou No .1’ ,Hippophae rhamnoides ‘China’s first generation hybrid’） as experimental materials in western Liaoning Province ,comparative experiments of the hardwood and softwood cuttages for Hippophae rh-amnoides were conducted .The survival rate was investigated .Result shows that ：the survival rate of softwood cut-tage of Hippophae rhamnoides are higher than that of hardwood cuttage for Hippophae rhamnoides under the same substance and density ;the survival rate by using two cutting methods have no significant difference under the same age of cuttage .
