| 采取随机区组试验，根据农田杂草群落的生态学原理，运用生态学方法，通过玉米苜蓿间种与玉米清种相对照，探讨了间种抗旱植物苜蓿对玉米田杂草群落与生长发育的影响。结果表明：清种玉米田中稗草和红蓼的重要值较高，为优
势种，间种苜蓿田中的优势种有红蓼、稗草、苘麻、反枝苋、龙葵、藜；在玉米各生育期，间种苜蓿田中的杂草生物量均低于清种玉米田处理，杂草株高大部分低于清种玉米处理；间种苜蓿穗长、穗行数、行粒数、穗重、穗粒重、百粒重和产量较清种玉米分别增加了6.6%、7.6%、2.2%、12.28%、9.9%、7.8%和4.3%。认为间种苜蓿能够控制杂草数量，抑制杂草生物量增加，苜蓿有抗旱保水的作用，使玉米产量有所提高。 |
| 英文摘要: |
| Through inter species of corn and alfalfa and corn-species comparison, discussed the impact of grow alfalfa to weed group and weed growth and development in corn fields. The result indicated that, the Echinochloa crusgalli and Polygonum orientale important value were higher in corn-species, were the idominant species, in inter-species of corn and alfalfa field the idominant species were the Polygonum orientale, Echinochloa crusgalli, Chenopodium album, Amaranthus retroflexus L
and Solanum nigrum Linn, Abutilon theophrasti Medic; Various growth stages in corn, inter species of alfalfa the weed biomass was lower than the corn species, most of the time, weed height was lower than the corn species; Inter-species of corn and alfalfa field, compared with the corn-species, ear length, ear rows, row rows, ear weight, grain weight per spike, weight of hundred grains and yield increased by 6.6%,7.6%,2.2%,12.28%,9.9%,7.8%,4.3%. Inter-species of alfalfa can control the number of weeds, inhibit weed biomass increased, increase corn production through of the alfalfa. This study could provide scientific bases for controlling weeds, drought resistance and water retention in corn field applied by exotic green manure plants. |
