以10个东北大面积推广的大豆品种(北豆18、绥农10、丰豆3、黑农28、东豆339、中黄13、合丰55、垦鉴豆35、黑农44和垦丰16)为材料,采用盆栽试验探索大豆在不同生育时期(V1、V3、V5、R2和R4)的根际土、根、茎和叶的甲醇提取液对瓜列当种子萌发的刺激效果。结果表明:不同大豆品种的甲醇提取液对瓜列当的诱导效果存在显著差异;中黄13的根际土对瓜列当的刺激作用显著高于其它品种;大豆V3和V5期的植株提取液对瓜列当的诱导作用最强;大豆的根、茎和叶对瓜列当的诱导效果为根>茎>叶。在瓜列当危害区,大豆可以作为瓜列当的“诱捕”作物。
Ten soybean varieties (Beidou 18, Suinong 10, Fengdou 3, Heinong 28, Dongdou 339, Zhonghuang 13, Hefeng 55, Kenjianu 35, Heinong 44 and Kenfeng 16) were used as materials to explore the effects of methanol extract from rhizosphere soil, root, stem and leaf of Soybean on the germination of melon seeds at different growth stages (V1, V3, V5, R2 and R4) The results showed that there was a significant difference in the induction effect of methanol extract from different soybean varieties on melon, the rhizosphere soil of Zhonghuang 13 had a significantly higher stimulating effect on melon as compared with other varieties. The plant extracts of soybean V3 and V5 The induction of melon when strongest; soybean roots, stems and leaves of melon when the induction effect of root> stem> leaf. Soybean can be used as a “trap” crop in Guarulhun Hazardous Area.
