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,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。研究结果表明,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明显提高地上生物量。萝北玉米田养鹅处理玉米产量较对照降低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40.64%,处理间差异显著(P<0.05)。

摘  要：
The relationship of field weed diversity and its aboveground biomass was studied in an agro-pastoral integration system of raising geese in cornfield in this paper. Field trials were conducted in Luobie, Heilongjiang,China and Linzhi, Xizang, China. There were two treatments, one was CK, spraying herbicides in cornfield in the middle of maize growth; the other was raising geese in cornfield from maize middle growth stage, without weed con-trol. Weed community characteristics(diversity indices and aboveground biomass) were evaluated just before apply-ing herbicide or breeding goose at maize middle growing stage, and maize yield were also analyzed after harvest. The results showed that weed diversity indices of Shannon-Wiener, Simpson, Margalef were significantly correlated with its aboveground biomass(P<0.05), that is, the increases in weed diversity could significantly increase weed aboveg-round biomass. In addition, raising geese in corn field patterns reduced corn yield compared to that of CK, with maize yield were decreased by 17.73 and 40.64% in Luobei and Linzhi, respectively. In Luobei, the maize yield dif-ference between treatments was not significant(P>0.05), while the difference in Linzhi reached significant level(P<0.05).
