1土壤处理
首先准备好的扦插基质。(蛭石、珍珠岩、泥炭,1:1:1.也可用沙、素沙壤土等)
在培养土壤中加入少量的炉渣,在扦插之前要对炉渣进行过筛、选择2至5毫米左右的颗粒,开水浸泡、消毒。控水凉干至不滴水后彻底搅拌混合备用。
2准备花盆
需要扦插多盆的可以使用简单的塑胶盆,扦插成功后上盆。选好花盆后需要装土,在花盆底部薄薄垫了点弹力絮或棉花也可以。
土壤装好后,浇透水,放在阳光下,晾晒备用。
3枝条剪取
剪向阳枝作插枝,新枝最好带点老枝。6月以后已半木质化新枝则不需带老枝。
剪插枝,老枝宜粗,有带叶的新枝。
用利刀削下插枝,大叶片留半叶二片,叶小的留二叶一芽,长约7-10cm,剪下枝的基部,剪口不平,组织受损,用利刀削去受损组织,一刀将基部削成斜面。下图是整理好的枝条。
4浸泡枝条
将生根粉按说明书要求配制,浸泡插枝基部。
5扦插
用干净(灭菌)木棒斜插打孔,深7-8cm,然后将插枝埋入,露出留叶的节。
插好一盆,将水浇透,使基质与插枝基部密切接触,蒙上保鲜膜保湿,上面开有透气孔,放有散射光照射的地方养护。
苗已成活,分植上盆。 info.b2b168.com/s168-69903943.htmlinfo.b2b168.com/s168-69903918.htmlinfo.b2b168.com/s168-69903891.htmlinfo.b2b168.com/s168-69903867.htmlinfo.b2b168.com/s168-69903844.htmlinfo.b2b168.com/s168-69903826.htmlinfo.b2b168.com/s168-69903801.htmlinfo.b2b168.com/s168-69903784.htmlinfo.b2b168.com/s168-69903735.htmlinfo.b2b168.com/s168-69903681.htmlinfo.b2b168.com/s168-69903597.htmlinfo.b2b168.com/s168-69903459.htmlinfo.b2b168.com/s168-69903437.htmlinfo.b2b168.com/s168-69903405.htmlinfo.b2b168.com/s168-69903288.htmlinfo.b2b168.com/s168-69903238.htmlinfo.b2b168.com/s168-69903190.htmlinfo.b2b168.com/s168-69903181.htmlinfo.b2b168.com/s168-69903041.htmlinfo.b2b168.com/s168-69903024.htmlinfo.b2b168.com/s168-69902972.htmlinfo.b2b168.com/s168-69902943.htmlinfo.b2b168.com/s168-69902916.htmlinfo.b2b168.com/s168-69902890.htmlinfo.b2b168.com/s168-69902819.htmlinfo.b2b168.com/s168-69902789.htmlinfo.b2b168.com/s168-69902760.htmlinfo.b2b168.com/s168-69902734.htmlinfo.b2b168.com/s168-69902663.htmlinfo.b2b168.com/s168-69902636.htmlinfo.b2b168.com/s168-69902551.htmlinfo.b2b168.com/s168-69902520.htmlinfo.b2b168.com/s168-69902489.htmlinfo.b2b168.com/s168-69902453.htmlinfo.b2b168.com/s168-69902407.htmlinfo.b2b168.com/s168-69902383.htmlinfo.b2b168.com/s168-69902361.htmlinfo.b2b168.com/s168-69902331.htmlinfo.b2b168.com/s168-69902262.htmlinfo.b2b168.com/s168-69902233.htmlinfo.b2b168.com/s168-69902191.htmlinfo.b2b168.com/s168-69902135.htmlinfo.b2b168.com/s168-69902110.htmlinfo.b2b168.com/s168-69902069.htmlinfo.b2b168.com/s168-69902043.htmlinfo.b2b168.com/s168-69902022.htmlinfo.b2b168.com/s168-69901951.htmlinfo.b2b168.com/s168-69901913.htmlinfo.b2b168.com/s168-69901883.htmlinfo.b2b168.com/s168-69901848.htmlinfo.b2b168.com/s168-69901814.htmlinfo.b2b168.com/s168-69901775.htmlinfo.b2b168.com/s168-69901707.htmlinfo.b2b168.com/s168-69901629.htmlinfo.b2b168.com/s168-69901600.htmlinfo.b2b168.com/s168-69901497.htmlinfo.b2b168.com/s168-69901455.htmlinfo.b2b168.com/s168-69901424.htmlinfo.b2b168.com/s168-69901376.htmlinfo.b2b168.com/s168-69901279.htmlinfo.b2b168.com/s168-69901231.htmlinfo.b2b168.com/s168-69901190.htmlinfo.b2b168.com/s168-69813348.htmlinfo.b2b168.com/s168-69901072.htmlinfo.b2b168.com/s168-69901038.htmlinfo.b2b168.com/s168-69901011.htmlinfo.b2b168.com/s168-69900986.htmlinfo.b2b168.com/s168-69900955.htmlinfo.b2b168.com/s168-69900925.htmlinfo.b2b168.com/s168-69900901.htmlinfo.b2b168.com/s168-69900872.htmlinfo.b2b168.com/s168-69900812.htmlinfo.b2b168.com/s168-69900771.htmlinfo.b2b168.com/s168-69900689.htmlinfo.b2b168.com/s168-69900634.htmlinfo.b2b168.com/s168-69900586.htmlinfo.b2b168.com/s168-69900557.htmlinfo.b2b168.com/s168-69900533.htmlinfo.b2b168.com/s168-69900506.htmlinfo.b2b168.com/s168-69900471.html
