Abstract:

Paulownia is a famous fast-growing species with characteristics of fast-growing,super property and multi-purpose and a major species for afforestation in plain region and etc.Since Paulozvnia top buds die of frost in the north of China,its natural trunk extension forms by means of fake two fork branches. Thereby,Paulozvnia has grest sharp degree of stem,small stem form rate,and its wood production is greatly lost.Therefore,For near 40 years Paulownia researchers have been studying Paulownia stem form including heredity improvement of Paulownia stem form,Paulozvnia robust nursery stock cultivation,artificial trunk extension,prune,the relationship between density of stand andmingled plantation and Paulownia stem form aS well as the relationship between above-mentioned measures and Paulownia witches broom etc.A1l research contents Above-mentioned are summarized and a certain number urgent problems about Paulownia stem form cultivation are put forward and discussed in this paper.

Key words: Paulownia, Stem form, Heredity improvement of stem form, Robust nursery stock cultivation, Artificial trunk extension, Summary
