植物的化感作用及其在林业经营中的运用

在自然界中植物的化感作用广泛地存在着,它与植物对光、水分、养分和空间的竞争一起构成植物间以及与其他生物间的相互作用,它影响着植物的分布、群落的形成和演替、种子的保存和萌芽、真菌孢子的萌发、氮素的循环等,在林业经营中有着广阔的运用前景。在对化感物质和化感作用的基本原理以及生物间存在的化感作用作综述性介绍的基础上,重点论述了化感作用对森林生态系统的影响,及其在森林更新、混交林培育和开发新型生物农药中的潜在价值,以期进一步推进对化感作用机制及应用的研究。

Allelopathy and Its Application in Forest Management

Allelopathy generally exists in nature,together with the plants'competition on light,water,nutrients and space,constitutes the interaction between different plants,and between plants and other organisms as well.All kinds of interaction affect the distribution of plants,the formation and succession community,conservation and germination of seeds,germination of fungus spore,and the circulation of nitrogen;allelopathy therefore has very broad application prospect in forest management.On the basis of summarize the rationale of allelochemical,allelopathy,and the allelopathy between organisms,the influences of allelopathy on forest ecological system,and its potential value on forest regeneration,cultivation of mixed forests and the development of new type biotic pesticide were described systematically.
