摘要 以重庆南川3年生药用栀子为材料,通过田间对比试验,研究了不同间作模式对栀子田间杂草的发生及产量的影响.试验结果表明,在栀子与薄荷、大豆、射干、金钱草间作系统中,栀子/薄荷间作在栀子整个生长期能较好地抑制田间杂草的发生,株数防效为60.26%~85.59%,鲜质量防效为80.59%~92.65%.而栀子/大豆间作在栀子生长后期能极显著抑制田间杂草的发生,8月与10月的株数防效分别为85.93%和77.05%,鲜质量防效分别为96.08%和91.18%.在栀子产量方面,栀子与射干或薄荷间作与单作相比可以显著提高其单株产量,增产率分别为37.61%和31.58%,二者差异不显著.综合杂草防控和产量两方面,栀子与薄荷间作,既能抑制田间杂草的发生,又能提高栀子的产量,在生产实践中值得大力推广. The three-year-old Gardenia was used as the material to study the effects of different intercropping patterns on weed control and yield of gardenia.The results show that in the intercropping systems of gardenia with Mentha canadensis,Glycine max,Belamcanda chinensis,and Lysimachia christinae,gardenia/Mentha canadensis intercropping could inhibit the occurrence of weeds in the field during the whole growth period,the strains control effect was 60.26%~85.59%,the fresh weight control was 80.59%~92.65%.And,gardenia/Glycine max intercropping could significantly inhibit the occurrence of weeds at the later stage.In August and October,their strains control effect was 85.93%and 77.05%,and the fresh weight control effect was 96.08%and 91.18%,respectively.In terms of the yield of gardenia,the intercropping of gardenia and Belamcanda chinensis or Mentha canadensis could significantly increase its yield per plant compared with single cropping,and their rates of growth are 37.61%and 31.58%,respectively,with no significant difference.Comprehensive weeds control and production,the intercropping of gardenia and Mentha Canadensis could both inhibit the occurrence of weeds in the field and increase the yield of gardenia,which deserved to be promoted in manufacturing practice.
