为扩大葡萄良种的繁殖系数,我们于1985年7月16日至31日进行全日照喷雾绿枝扦插试验。试验结果表明,这是发根快而多、成活率高、管理方便的快速繁殖方法之一。 料材与方法 1.插条处理:供试插条为巨峰夏季副梢修剪枝条。将半木质化的枝条采下后随即浸入清水中。单芽插条于芽上1～1.5厘米处平剪,芽下2～3厘米处斜剪;双芽插条顶端于芽上1～1.5厘米处平剪,下端紧靠芽下斜剪。顶端叶片均剪留三分之一左右,下端理平并捆成若干小札,基部用500ppmNAA处理10秒钟,用湿布盖好待插。
To expand the breeding coefficient of grape varieties, we conducted a full-day spray green shoot cutting test from July 16 to 31, The test results show that this is one of the rapid propagation methods that hair root is much faster, survival rate is high and management is convenient. Materials and methods 1. Cuttings processing: test cuttings for the summer peak tip trim pruning branches. The semi-lignified shoots were taken immediately after immersion in water. Single bud cuttings in the bud on the 1 to 1.5 cm at the level of cut, 2 to 3 cm under the bud oblique cut; the top of the double bud cuttings on the bud 1 to 1.5 cm at the shear, the lower end of the spike oblique cut. The top leaves are about one-third cut, the bottom of the flat and bundled into a number of small Sapporo, base with 500ppmNAA treatment for 10 seconds, covered with a damp cloth to be inserted.
