中文摘要:
      试验对农牧一体化方式下玉米田养鹅模式和传统种植模式的田间杂草群落进行对比研究,统计分析放牧前各杂草的生物多样性指数和地上生物量,以期初步探讨玉米田养鹅模式下物种多样性指数与杂草生物量之间关系。萝北、林芝两地Shannon-Wiener多样性指数、Simpson优势度指数和Margalef物种丰富度指数与地上生物量指标之间均显著相关(P<0.05),说明玉米田养鹅系统群落物种多样性与生产力之间紧密相关,物种多样性的增加可以明显提高地上生物量。此外萝北玉米田养鹅处理玉米产量较对照降低了17.73%,处理间差异不显著(P>0.05),林芝玉米田养鹅处理下玉米产量较对照降低了40.64%,处理间差异显著(P<0.05),玉米田养鹅模式相比传统种植模式降低了玉米产量。
英文摘要:
      The field weed community was studied in agro-pastoral integration system in this paper. Prior to statistical analysis of biodiversity indices of weed community and aboveground biomass, the relationship between species diversity and productivity was determined in the model of raising geese in cornfields. The results showed the indices of Shannon-Wiener, Simpson, Margalef was significantly correlated with the aboveground biomass(P<0.05), so species diversity and productivity is closely related and the increases in species diversity could significantly increase the aboveground biomass. In addition, raising geese in corn field patterns reduce corn yield compared to traditional planting patterns. The yield of maize in the Luobei corn field decreased by 17.73%, and the difference between treatments was not significant (P>0.05). Compared with the control, the yield of corn in the Lingzhi cornfield was reduced by 40.64%, and there was a significant difference between treatments (P<0.05).
