摘要
河北杨是杨柳科优良品种,耐干旱、瘠薄的土壤,抗病虫害能力强,不受天牛危害,是我国西北地区重要的乡土树种之一。但因繁殖困难,导致种苗供应不足。文章研究了不同基质和不同浓度的生长素对河北杨扦插生根的影响,结果表明:在河北杨的扦插育苗中,选用50%的园土+30%的河沙+20%珍珠岩混合基质,并用浓度为600 mg/L的NAA溶液处理插穗,对河北杨生根具有明显的促进作用。
The paper carried out a study of different substrates and different concentrations of auxin effect on Ponulus hopeiensis Hu rooting cuttings.The result showed that there was an obvious role for improving rooting when using the mixed substrate of 50% garden soil ＋ 30% riversand ＋ 20% perlite and treated with cuttings with concentration of 600 mg/L NAA.
