乌桕和栗分别是浙江省重要的木本油料和粮食树种。生产实践和科学研究证明,乌桕和栗采用嫁接繁殖,不仅能促使幼树速生丰产,而且还能保持品种原有的优良特性。但是,目前本省除极少数地区有习惯应用嫁接繁殖外,一般都采用实生繁殖。为了使这一嫁接经验,迅速在全省范围内遍地开花、结果,我们特于1962—1963年在临安浙江天目林学院用二年生的乌桕和板栗苗进行了不同嫁接时期和方法等的试验,以期进一步掌握其规律,便于群众应用。现将试验的初步结果简报如下:
Wuhu and chestnut are important woody oil and grain species in Zhejiang Province. Production practice and scientific research have proved that the use of grafting and propagation of black and white chestnut can not only promote quick and high yielding of saplings, but also maintain the original good characteristics of the cultivars. However, at present, there are only a few areas in our province that are accustomed to applying grafting and breeding, and generally adopt real-life breeding. In order to make this grafting experience quickly spread throughout the province, we conducted a pilot study of different grafting times and methods with two-year-old Osmunda japonica and chestnut seedlings at Tianmu Forestry College in Lin’an, Lin’an, Zhejiang Province, from 1962 to 1963 with a view to further Master the law, to facilitate the masses to use. The preliminary results of the trial are now briefly summarized as follows:
