According to the requirement of the development of economy on the land within mass degenerative ecosystems in subtropical hilly areas in China, small fruits were recommended by authors as ideal crops on the basis of economical and ecological analysis. With the theory of “Habitat Factors Analysis”, the possibility of the introduction of blackberries in Jiangsu province has been verified. Directing at the differences of water, heat and soil factors between the original producing area and the introductional area, claims for site selection and essentials of cultivation were suggested, e.i. mainly (1) trellis; (2) soil improvement; (3)mulching and (4) systematically monitoring of pests and diseases. It proved that the development of small fruits should be preceded and ensured by the researches of fruit processing. Mean while, wild Rubus germplasms in China were investigated and outstanding species were selected, and some of them have been found extremely rich in VE,SOD and Se. Those were thought valuable in blackberry and raspberry breeding in future. The prospect of blackberry production and the possibility of raspberry introduction in subtropics of China were discussed.

根据我国亚热带丘陵山区大量退化生态系统急待改良的需要,在经济生态学分析基础上,提出以小果类作为开发南方丘陵山区的作物之一。应用“生境因子分析法”理论,论证了黑莓在江苏省引种的可行性。针对黑莓原产区与新引种区水热和土壤因子的差别,提出了选地和及时立支架、土壤改良、土面覆盖、病虫害调查与防治四项栽培技术要点。论证了小果类发展应以加工研究为前导和保证。同时开展了大规模国产悬钩子野生种质资源调查,发现存在富含VE、SOD和微量元素Se的种质,发掘出21种优良种类,分别有直立性强、丰产、果大、色素含量高、抗病虫等优点,是未来黑莓和树莓育种值得注意的原始材料。最后指出下世纪我国黑莓和树莓生产的前景。

The characteristics of temporal dynamics and spatial distribution of forest soil seed bank and their effects on natural regeneration were reviewed in this paper.The density of the seed bank of forest soil,which is affected by the types and ages of forest,is lower than that of cultivated land and grassplot,and can vary widely.The extent to which the composition of forest soil seed bank is influenced by its counterpart plantation depends on the stages of succession.The dynamics of forest soil seed bank is the combined effect of periodical and random factors.It is suggested that forest soil seed bank is the material base of forest regeneration,and the configuration and function of forest soil seed bank would influence the ability and the direction of natural forest regeneration.According to the characteristics of forest soil seed bank and obstructive factors influencing regeneration,some artificial measures can be adopted to accelerate natural regeneration.Studies on the forest soil seed bank should focus on the application of basic theories of disturbed ecology,and regard the reconstruction of degenerative ecosystem and the succession of populations in the ecotone as the main contents to study.As for the research method,it is advisable to employ long-term and located observations.

论述了森林土壤种子库的特点 :(1)森林土壤种子库密度小于耕作土壤和草地 ,并且受森林类型和年龄的影响 ,变化幅度很大 ;(2 )森林土壤种子库的种类组成在森林的不同演替阶段 ,受其地上植被影响的程度不同 ;(3)森林土壤种子库的动态变化是周期性因数和随机性因数的结合 .并从土壤种子库的时间动态和空间分布角度 ,分析了土壤种子库对天然更新的影响 .森林土壤种子库是天然更新的物质基础 ,种子库的结构和功能影响天然更新的能力和方向 ,因此能影响土壤种子库格局变化的各种因子或措施 ,均能显著地促进或妨碍森林的天然更新 .根据森林土壤种子库的时空格局特点及影响更新的障碍因子 ,可以采用人工的辅助措施促进更新 .同时 ,对于森林土壤种子库的研究应着眼于应用干扰生态学的基本理论 ,以退化生态系统的重建和群落交错区的演替为主要内容 ,研究方法应以长期定位观测为宜 .
