摘要: 通过比较不同部位、不同浓度、不同生长年限的三七水提液化感作用强弱,筛选适宜与三七轮作的植物。以小麦、玉米、油菜为受体植物,采用正交试验法比较三七水提液对这3种供试植物种子萌发和幼苗生长的化感作用。(1)三七各部位水提液对小麦、油菜种子萌发及幼苗生长均具有抑制作用。(2)低浓度的三七水提液可以促进玉米种子萌发和幼苗生长,高浓度时则起到抑制作用。(3)不同生长年限及不同部位的三七水提液对受体植物的化感作用也有显著差异。各供试因素中,以不同浓度三七水提液对受体植物的影响最为显著。玉米是3种受体植物中最适合与三七轮作的植物,这可能与玉米对三七化感作用的耐受性较强有关。

Abstract: The aim was to compare the strength of allelopathy of Panax notoginseng aqueous extracts through different parts, different concentrations and different growth years, and select suitable plants that could rotate Panax notoginseng. Wheat, corn and rape was selected as receptors, the allelopathy of Panax notoginseng aqueous extracts on seed germination and seedling growth was compared with orthogonal test on these three seeds. (1) Aqueous extracts of various parts of Panax notoginseng inhibited seed germination and seedling growth of wheat, rape. (2) Panax notoginseng aqueous extracts in low concentrations could promote seed germination and seedling growth, but inhibit in high concentrations. (3) Allelopathies of Panax notoginseng aqueous extracts of different growth years and different parts on recipient plants were also significant differences. In all test factors, different concentrations of Panax notoginseng aqueous extracts had the most significant impact on recipient plants. Corn was the best suited plants that could rotate Panax notoginseng in three recipient plants, and it might be relate to the strong tolerance of corn on allelopathy of Panax notoginseng. Key words: Panax notoginseng; aqueous extracts; allelopathy; orthogonal test method
