为进一步提高毛白杨繁殖率和苗木质量,简化操作,降低成本,我们在分析埋条和插条优缺点的基础上,取长补短,试用了既具备埋条、插条优点,又能消除各自缺点的综合育苗技术,即深沟大垄锔形埋插育苗法,顾名思义,就是育苗前先做成深沟大垄,再将种穗中间平埋,两头直插,象锔子一样锔在沟底的一种育苗方法。其主要优点是:操作简便,省工省料,容易推广,成苗率高,成本低,质量好。现初报如下:
In order to further improve Populus tomentosa breeding rate and seedling quality, simplify operation and reduce costs, based on the analysis of the advantages and disadvantages of the buried strips and cuttings, we can learn from each other’s strengths and weaknesses, both the advantages of embedded strips and cuttings, but also to eliminate their respective shortcomings Comprehensive nursery technology, that is, deep furrows big ridge type embedded planting nursery law, as the name suggests, is made before the nursery deep furrows, and then the middle of the seed buried flat, two straight line, like a prickly heat in the ditch bottom A breeding method. Its main advantages are: easy to operate, save labor and materials, easy to popularize, high seedling rate, low cost and good quality. Now reported as follows:
