马尾松扦插繁殖技术的研究

马尾松历来被认为是扦插极难生根树种,是良种繁育的主要障碍之一,为探索马尾松扦插育苗技术,1989～1991年进行了马尾松扦插育苗、提高繁殖系数以及扦插苗造林试验。结果表明:通过修剪诱发萌芽枝作插穗,并合理选择扦插基质、扦插时间,经生根促进剂处理和全光喷雾管理,扦插生根率可达90％以上;幼树插穗繁殖系数可达2～5倍;扦插苗造林成活率和生长量均优于实生苗,使该项技术在生产上可以有效地应用。

Study of Cutting Propagation Techniques for Pinus massoniana

It is considered difficult for Pinus Massoniana to root when planted with cuttings. In order to study the relevant method, the experiments of nursing with cuttings, raising vegetative rate and establishing plantation with cutting stock have been done from 1989 to 1991. The results show that cuttings which are sprouted affter the pruning, and treated with root growth: helping matter have a rooting rate of over 90% when planted in a bed type appropriately selected and put in control of light and spray; and that cutting's vegetative rate taken from young tree are as many as 2-5 times;survival and growth rate of plantation with cuttings is obviously higher than that of plantation with seedlings.
