基于AMMI模型的三七化感作用稳定性分析(1)
[摘要]为明确不同作用途径下三七化感作用的变化，筛选适宜的轮作植物，应用AMMI模型分析了三七对不同轮作植物化感作用的稳定性。研究结果表明：AMMI模型可应用于植物化感指数的稳定性分析，且优于传统的回归模型分析法;利用对应分析图能够直观评价各轮作植物的稳定性和作用途径(环境条件)的分辨力;鄂粳杂1号(g6)为强化感作用稳定型，而云瑞1号(g9)属弱化感作用稳定型，是较为理想的三七轮作植物。研究结果为筛选适宜与三七轮作的植物提供了新的方法，为建立合理轮作制度提供了理论和实验依据，同时对中药材种质资源合理评价也具有借鉴作用。

[Abstract]This paper is aimed to study the differences of allelopathic effects of Panax notoginseng under different allelopathic chemicals resources and selection of appropriate rotation crops. The additive main effects and multiplicative interaction (AMMI) model had been used to evaluate the stability of allelopathic effects of P. notoginseng on the varieties of corn， wheat and rice properly. The model could use not only to evaluate the stability of non-regional trial data but also explore the interaction between the rotation crop genotypes and donor substances more efficiently. Meanwhile， correspondence analysis can be used in the AMMI to evaluate genotype stability and donor substances. Ejingza No. 1 (g6) had stronger allelopathic effects with high stability， but Yunrui No. 1 (g9) which was appropriate rotation crop genotype， had weaker allelopathic effects with high stability. These findings will aid in choosing appropriate rotation crops and establishing proper rotation system.

三七Panax notoginseng(Burk.)F.H. Chen是五加科人参属植物，具有显著的活血化瘀、降低血脂、疗伤和强壮滋补功效[1]。近年来随着人们对其药用价值认识的逐渐加深，其需求量进一步加大，栽培面积也不断扩大。由于三七喜温暖阴湿，再加上连年大面积单一种植，导致其根际土壤生态环境恶化，因此连作障碍现象十分严重[2]。研究表明，轮作是生产上恢复土壤地力、减少病虫害，减轻药用植物连作障碍的重要措施[3]。作者实地调查也发现，轮作是目前生产上消减三七连作障碍效应最为直接有效的技术措施。
为从化感作用角度揭示轮作消减三七连作障碍的作用机制，作者曾分析了三七茎叶、根水浸液以及绒根对玉米、小麦、水稻等轮作植物的化感作用。结果发现，三七对不同轮作植物的化感作用不完全相同，而三七的茎叶、根水浸液及绒根对同一种轮作植物产生的化感作用强弱也并不完全一致。从应用角度考虑，只有在茎叶、根水浸液、绒根等不同化感物质来源条件下，三七对所选轮作植物的化感作用都较弱，即要求“弱化感作用稳定型”，这样才能最大程度减小三七对轮作植物的影响，保证轮作植物正常生长。因此，为了建立合理的轮作制度，探讨三七对轮作植物化感作用在不同化感物质来源条件(不同环境条件)下的变化，即进行化感作用的稳定性分析很有必要。, 百拇医药(张子龙 侯俊玲 王文全)
