为研究鲜食蚕豆大棚覆盖条件下的产量表现，挖掘增产潜力，探索提高大棚耕地产出的有效途径，以莴苣、黑塌菜、豌豆3种蔬菜为试验材料，采用大区对比方法对大棚鲜食蚕豆100 cm等行、130 cm+70 cm宽窄行和160 cm+40 cm宽窄行3种行距配置及间作莴苣、黑塌菜和豌豆3种蔬菜的产量进行研究。结果表明：蚕豆纯作时，100 cm等行产量最高，130 cm+70 cm宽窄行、160 cm+40 cm宽窄行分别减产9.25%和22.27%，差异显著；间作莴苣、黑塌菜和豌豆后，160 cm+40 cm宽窄行的蚕豆鲜荚分别是增产9.72%、增产14.91%和减产16.98%；130 cm+70 cm宽窄行的蚕豆鲜荚分别减产6.27%、增产5.86%和减产18.41%；100 cm等行种植的蚕豆鲜荚分别减产10.86%、增产3.23%和减产24.07%；3种行距配置间作的3种蔬菜产量，均以160 cm+40 cm宽窄行最高，130 cm+70 cm宽窄行次之，100 cm等行种植最低。由此得出，行距配置对大棚鲜食蚕豆产量有着显著影响，蚕豆间作蔬菜时其产量表现与行距配置、蔬菜种类密切相关。

The present studies were carried out to characterize effects of three different spacing forms and three intercropping patterns(fresh-eaten broad bean /lettuce, fresh-eaten broad bean /heitacai and fresh-eaten broad bean /pea) on the yield of fresh-eaten broad bean in plastic greenhouse. Results showed that the broad bean yield of sole cropping in wide-narrow row plantation with a distance of (130 cm+70 cm,T1) and (160 cm +40 cm,T2) patterns are significantly less than that of the (100 cm +100 cm,T0) pattern, about 9.25% and 22.27%, respectively. The yields of fresh-eaten broad bean about three different intercroppings vegetables between rows is adopted to grow lettuce, heitacai and pea, comparing to broad bean sole cropping respectively, were 9.72% and 14.91% increase ,and 16.98% decrease in treatment T2, and 6.27% declined, 5.86% growth and 18.41% down in treatment T1, 10.86% fall, 3.23% rose and 24.07% contracted in treatment T0. Our results implied that the three kinds of vegetable production about three different spacing forms indicates the following order of importance:T2>T1>T0.
