一、前言桉树是速生树种,适于我省亚热带季风气候区生长,在赣南地区已有三十余年的栽培历史。近年来,我省各地推广桉苗造林。在培育桉苗过程中,能看到幼苗根颈部位有一个(或数个)突出物。据了解,广东、广西、福建、湖南等省苗圃的桉树幼苗和林地的定植都发现有这种突出物,分布广,数量多。目前文献上讨论木质块茎对苗木的影响很少论述。现把多年的观察结果整理如下,为苗木生产提供技术措施的依据。
I. Introduction Eucalyptus is a fast-growing tree species suitable for the growth of the subtropical monsoon climate in our province. It has been cultivated for more than 30 years in southern Jiangxi. In recent years, promote eucalyptus afforestation throughout the province. During the cultivation of eucalyptus seedlings, one (or more) prominences can be seen in the root of the seedling. It is understood that in Guangdong, Guangxi, Fujian, Hunan and other provincial nursery eucalyptus seedlings and planting of woodland have found this prominence, widely distributed, the number of. The current literature on the effects of woody tubers on seedlings is seldom discussed. The results of many years are now organized as follows, for the production of seedlings provide the basis for technical measures.
