在分析不同植物互作效应的基础上,就互作效应在农林复合系统中对植物体内养分、土壤养分有效性及植物生物学产量等的影响进行了概述,(1)互作促进了植物根系生长,使植物根系表现出较强的竞争作用,也有利于根系间的养分竞争;(2)植物之间的他感作用普遍存在于自然生态系统及栽培生态系统中,在植物资源配置时应充分利用这种相生相克作用;(3)互作促使植物体内的养分转移,改善体内的养分状况,达到植物之间养分互补;(4)互作可以有效地提高土壤肥力,改善土壤的养分状况和根际养分吸收环境,维持植物生产力;(5)互作能更有效地利用光、热、水、土和养分等资源,并减轻病虫危害,表现出明显的产量优势。在豆科与非豆科植物互作中,豆科植物的生物固氮作用为其互作植物提供了氮素营养保证,这种形式互作的产量优势通常在缺氮情况下表现更为明显。 Based on the analysis of the interaction effects of different plants, the effects of interaction effects on plant nutrients, soil nutrient availability and plant biological yield were summarized in the agroforestry system. (1) Interaction promoted plant root Growth, so that the plant roots showed a strong competitive role, but also conducive to nutrient competition between the roots; (2) the sense of his role among plants is widespread in natural ecosystems and cultivation ecosystems in the allocation of plant resources should Take full advantage of the role of phase-A-phase g; (3) interaction to promote the transfer of nutrients in plants to improve the body’s nutrient status, to achieve nutrient complementarity between plants; (4) interaction can effectively improve soil fertility and improve soil nutrient status and Rhizosphere nutrients to absorb the environment, to maintain plant productivity; (5) interaction can more effectively use light, heat, water, soil and nutrients and other resources, and reduce pest damage, showing obvious yield advantage. In the interaction between leguminous and non-leguminous plants, the biological nitrogen fixation of legumes provides a nitrogen nutrient guarantee for their interacting plants. The yield advantage of this form of interaction is usually more pronounced in the absence of nitrogen.
