由于新疆杨扦插育苗在选择种条上要求严格,它必须选用一年生中下部枝条,且种条直径要求一公分左右,愈合根也缓慢,假活现象明显,容易失去水分平衡,与钻天杨,杂交杨相比,扦插成活率较低。两种条上部的枝条和直径小于0.5公分的枝条,扦插几乎就不成活、生产中常常把三分之一的种条,弃为燃料。为了充分利用这部分枝条,扩大种源,摸索新疆杨梢部枝条育苗成活规律,变废为利,为加速发展新疆杨,我们初步研究了一种弓形埋条育苗方法。
Due to the strict selection of cutting seedlings, it is necessary to select middle and lower branches of annuals. The diameter of the needles is about one centimeter and the heal roots are also slow. The false live phenomenon is obvious and the water balance is easily lost. Compared to cuttings lower survival rate. Two kinds of branches above the branches and branches less than 0.5 cm in diameter, cutting almost no survival, production is often one-third of the species of barrels, discarded as fuel. In order to make full use of this part of the branches, expand the provenance, explore the law of survival of the branches of Xinjiang Yang shoot growth and turning waste into profit, in order to accelerate the development of Xinjiang Yang, we preliminary study a bow buried breeding method.
