摘　　要：研究了240g/L乙氧氟草醚EC不同施用量对大蒜田杂草婆婆纳、野苋菜和猪殃殃的防除效果,并测定了各处理的大蒜头产量和婆婆纳、猪殃殃对大蒜田氮、磷、钾养分的吸收量。结果表明,240g/L乙氧氟草醚EC能有效控制大蒜田婆婆纳、野苋菜和猪殃殃的危害;施药后大蒜产量比清水对照增产31.62%～42.64%,是一种防除大蒜田杂草的高效药剂;施药后最多可减少婆婆纳和猪殃殃对每公顷大蒜田吸收氮26.120kg、磷1.270kg、钾12.300kg,大大降低了杂草对大蒜田养分的吸收。Efficiency of different concentration of 240 g/L oxyfluorfen for Veronica didyma Tenore, Amaranthus spinosus L.,and Galium aparine L. in garlic field were compared. The yield of garlic under different concentration treatment and the absorption quantity of N, P, K of Veronica didyma Tenore, Galium aparine L. were ascertained by measuring. The result showed that, 240 g/L oxyfluorfen had high efficiency in controlling Veronica didyma Tenore, Amaranthus spinosus L., and Galium aparine L.. Compared with the treatments of water,the yield of treatments with 240g/L oxyluorfen was 31.62%~42.64% higher. The deducing absorption of N, P, K in Veronica didyma Tenore and Galium aparine L. were 26.120kg/hm2, 1.270 kg/hm2, 12.300 kg/hm2 by the treatment of 240g/L oxyfluorfen.
