中文摘要：

为探明蚕豆不同间作体系和种植密度对结瘤和植物生长的影响.本研究通过田间小区试验调查了蚕豆//小麦、蚕豆//油菜、蚕豆//大蒜、单作蚕豆、单作小麦、单作油菜和单作大蒜在20,30,45 cm等3种行距下蚕豆和间作作物的根瘤重、生物量和株高差异.结果表明,间作对蚕豆结瘤的影响因种植密度的差异表现出不同的效应.种植行距为20 ～ 30 cm时,与大蒜间作的蚕豆根瘤重显著高于其他间作和蚕豆单作的处理;当间距为45 cm时,单作蚕豆的根瘤重要显著高于间作的处理.同样,间作的蚕豆地上部生物量也与种植密度有关.在间作间距介于20～30 cm,小麦促进蚕豆地上部生物量增加;油菜在种植间距为20 cm时抑制蚕豆生长.与蚕豆间作基本不抑制作物生长,当间作间距分别为30,45 cm时,蚕豆显著促进油菜和小麦的地上部干重的增加.结果表明,大蒜促进蚕豆结瘤效果最明显,而30 cm的间距对间作作物双方生物量的影响最轻.

英文摘要：

The present study was carried out to evaluate the influence of intercropping mode and planting density on faba bean nodulation and plant growth.Root nodule weight and biomass about three intercropping system of faba bean//wheat,faba bean//rape and faba bean//garlic and four monocropping systems of faba bean,wheat,rape and garlic with 3 planting densities in field experiment was examined.The result was showed that the effect of intercropping on nodulation of baba bean was different with planting density.The nodule weight of faba bean intercropped with garlic was significantly higher than other intercropping modes and monocropping when line space was from 20 to 30 cm.Nodule weight of faba bean in monocropping with the line space of 45 cm was significantly higher than other intercropped treatments.Meanwhile,shoot biomass of faba bean was correlated with planting density.Shoot dry weight of faba bean was increased by wheat when line space was from 20 to 30 cm.However,shoot dry weight of baba bean was inhibited by rape when line space was 20 cm.Faba bean intercropping did not influence plant growth of the intercropped crops.Faba bean promote plant growth of wheat and rape growth of shoot when line space was 30 cm and 45 cm,respectively.The above results indicated that garlic was the best intercropped crop to increase nodulation with faba bean; the biomass of both faba bean and intercropped crops was less influenced when line space was 30 cm.
