摘　　要：【目的】研究比较在室外盆栽条件下,几种豆科植物种子干粉拌种处理对伽师瓜种子发芽及植株生长的影响,筛选出对伽师瓜种子发芽抑制作用较小,且对伽师瓜植株生长具有较好促进作用的豆科植物,为苦豆子绿肥开发提供依据。【方法】以伽师瓜为供试作物,选取苦豆子、三叶草、苜蓿、豌豆、豇豆和绿豆等6种豆科植物为试材,研究不同豆科植物种子干粉对伽师瓜种子发芽、伽师瓜植株形态以及相关生理生化指标的影响。【结果】三叶草种子干粉处理的发芽率、发芽势和发芽指数均最小,发芽率、发芽势和发芽指数分别为(65.0±0.105)、(62.5±0.088)和(1.188±0.173),绿豆种子干粉处理的萌发率、发芽势和发芽指数均大于其他处理组,发芽率、发芽势和发芽指数分别为(82.5±0.068)、(80.0±0.112)和(1.425±0.176),绿豆种子干粉对伽师瓜种子萌发的抑制性最弱。苦豆子种子干粉处理的伽师瓜植株高度、植株粗度和叶片总面积第5次测量的净增长量分别为(160.313±22.129)、(0.373±0.107)和(160.313±22.129)。苦豆子种子干粉处理的伽师瓜植株总干重和叶片叶绿素含量分别为(4.220±0.157)和(0.445±0.018)。【结论】与其他豆科植物相比,苦豆子种子干粉对伽师瓜植株形态以及相关生理生化指标具有更好的促进作用。在开发伽师瓜绿肥时,苦豆子种子可以作为优先选择对象。【Objective】To careen out the leguminous plants with less inhibitory effect on seed germination and better promoting effect on plant growth by comparing the effects of Leguminosae seed dry powder leguminous plants on seed germination and plant growth in outdoor pots with a view to provide basis for the development of green fertilizer of bitter bean.【Methods】With Jiashi melon as the test crop,six legumes,including Sophoraalopecuroides,Trifoliumrepens,Medicago sativa,Pisumsativum,Vignaunguiculata and Vignaradiata were selected as test materials to study the effects of different Leguminosae seed dry powder on the germination of Jiashi melon seeds and Jiashi melon plant morphology and related physiological and biochemical indicators.【Results】Dry seed powders of 6 legumes had inhibitory effects on the germination of Jiashi melon seeds,among which cloverseeds had the strongest inhibitory effects and Vignaradiata seeds the weakest inhibitory effects.Sophoraalopecuroides seed powder had a higher promoting effect on the plant height,leaf area,dry weight and chlorophyll content of Jiashi melon than other legume seeds.【Conclusion】Compared with other leguminous plants,the dry seed powder of Sophoraalopecuroides has a better promotion effect on the plant morphology and related physiological and biochemical indexes of Jiashi melon.Therefore,in the development of Jiashi melon green manure,Sophoraalopecuroides seeds can be selected as a priority choice.
