摘　　要：为筛选出适宜豫南地区弱筋小麦轮作的夏季绿肥品种,选择鲁菁1号田菁、印度柽麻、羊角豆、决明、赤小豆、铜山小绿豆和小槐花园叶绿豆7个夏季绿肥品种进行小区种植试验,并分析不同绿肥品种生育期、农艺性状及盛花期养分含量等指标。结果表明:鲁菁1号鲜重为31032 kg/hm^(2),氮的养分积累量41.39 kg/hm^(2),磷的养分积累量43.28 kg/hm^(2),钾的养分积累量8.66 kg/hm^(2),其养分积累量最高,是弱筋小麦轮作夏季绿肥的首选品种。In order to screen out summer green manure varieties suitable for weak gluten wheat rotation in southern Henan,this paper selected seven summer green manure varieties(including Sesbania cannabina Lujing No.1,Tamarix indica,Abelmoschus esculentus,Cassia obtusifolia,Vigna umbellata,Tongshan small mung bean,Small Robinia-flower Round-leaf)for plot planting test,and analyzed the growth period,agronomic characters and nutrient content in flowering period of different green manure varieties.The results showed that the fresh weight of Lujing No.1 was 31032 kg/hm2,the nutrient accumulation of N was 41.39 kg/hm2,P was 43.28 kg/hm2,and K was 8.66 kg/hm2,its nutrient accumulation was the highest,which was the first choice for weak gluten wheat rotation in summer.
