杨树是速生树种,近年来随着植树造林事业的迅速发展,育苗面积不断扩大,提高育苗质量实为当务之急。杨树育苗广泛采用插条方法,此法虽已经过长期生产实践,但仍存在若干技术问题,若不加以解决,则不能适应杨树发展形势的要求。因此,我们从1973年起,对于在生产中接触到的有关插穗质量、抹芽效果等问题,进行了试验。现将部分试验的初步情况总结如下。 Poplar is a fast-growing tree species, in recent years with the rapid development of afforestation, nursery area continues to expand, raising seedling quality is a top priority. Poplar seedlings widely used cuttings method, although this method has long been the practice of production, but there are still some technical problems, if not addressed, you can not meet the requirements of poplar development situation. Therefore, since 1973, we have conducted experiments on the quality of cuttings, the effects of sprouting buds and so on, which have come into contact with our production. Now part of the trial of the initial situation is summarized as follows.
