豫楸1号扦插技术模式研究

Study on Cutting Vegetative Propagation Pattern of Catalpa bungei cl.‘Yu-1’

通过对楸树良种—豫楸1号不同插条类型、插条不同部位、不同激素处理及处理时间、不同扦插基质上进行扦插试验,得出一套能够将难生根树种楸树扦插成活率提高到90%以上的扦插技术模式。认为豫楸1号采用1年生苗干平埋复幼催生嫩枝作为插条、以IBA︰NAA=2︰1混配,浓度500μl/L速蘸、以蛭石为基质的扦插技术模式能够极大地提高扦插成活率。

Through experiment on breeding technology of cutting of good Catalpa bungei strains ofseeds Catalpa bungei cl.＇Yu-1＇ by unlike cutting wood type , location, hormone and diversity cutting base materials, the artical reaches one cutting technology pattern that can improve Catalpa bungei cutting survival percentage of taking root to 90% above. It. is known that Catalpa bungei is difficult to take root. It is cosidering that adopts a tie to bury again young germ on the cutting strip delivery on the spray action rtansplants a cutting with IBA：NAA=2：1,dips speeded in thickness 500μl/L,the maximun field improves taking lennilte as base material cutting technology the pattern can improve Catalpa bungiei cl.＇Yu-1＇ cutting survival percentage.
