人工林化感效应防控研究与展望

人工林化感效应是林木释放的化感物质对自身或其他植物与土壤生态系统产生的促进或抑制作用，是导致人工林连作障碍的重要原因。探究人工林化感效应防控措施，可为营造结构稳定、功能高效的人工林生态系统提供理论与实践依据。文中从立地条件选择、林分空间结构优化、培育抗逆性品种、补偿土壤营养水平、施用微生物菌剂等方面总结主要防控措施，提出未来从防控化感效应视角培育人工林时，可深入研究基于细胞与分子水平的生态育种技术、多树种共存机制和群落构建技术、有机肥与化感物质的互作效应与配施技术，以及探讨微生物和酶的加合作用对化感物质的影响机制与抑制技术。

Research and Prospect on Allelopathy Effect Prevention and Control of Plantation

Allelopathy effect of plantation refers to the promotion or inhibition of allelochemicals released by trees on themselves or on other plants and soil ecosystem, which is an important reason behind the obstacles against continuous cropping. The research on allelopathic effect prevention and control of plantation can provide theoretical and practice bases for establishing a plantation ecosystem with stable structure and efficient function. This paper concludes the main prevention and control measures from the aspects of site condition selection, optimization of stand spatial structure, cultivation of stress resistant varieties, compensation of soil nutrient level and application of microbial agents, and proposes to further study the ecological breeding technology based on cell and molecular level, the coexistence mechanism of multiple tree species and community establishment technology, and the interaction effect of organic fertilizers and allelopathy and its application technology, and to explore the influencing mechanism of microorganism and enzyme on allelochemicals and the inhibition technology, when plantation is cultivated in the future from the perspective of control effect.
