摘　　要：在信阳市种植6个夏季绿肥品种,设接种和不接种根瘤菌2个水平、共12个处理进行小区种植试验。通过种植筛选适宜冬小麦减肥生产的夏季绿肥品种,为翻压利用做准备。从多方面对不同夏季绿肥品种进行综合评价。结果表明:12个处理的出苗期差别不大,巨丰和汾豆牧绿2号现蕾期最早,田菁现蕾期最晚。汾豆牧绿2号始花期最早,田菁始花期最晚。汾豆牧绿2号盛花期最早,田菁盛花期最晚,但均能在8月底压青沤肥。盛花期鲜草产量差异大,接种根瘤菌的田菁鲜草产量最高,巨丰和郑1307植株氮磷钾的养分含量综合比较最好。氮磷钾的养分积累量均以接种根瘤菌的田菁最高。接种根瘤菌的田菁能降低土壤温度,提高土壤湿度。增加土壤稳定性和抗风蚀能力,更能提高土壤肥力。初步筛选出与冬小麦轮作的夏季绿肥首选品种为田菁(接种根瘤菌)。Six summer green manure varieties were planted in Xinyang City,and inoculation and non-inoculation of rhizobia were set up,and a total of 12 treatments were set up for planting experiments.Summer green manure varieties suitable for fertilizer reduction of winter wheat were selected by planting and screening to prepare for the utilization.The green manure varieties were comprehensively evaluated from various aspects.The results showed that there was little difference in the emergence stage of the 12 treatments,with Jufeng and Fendou Mulv 2 budding stage being the earliest,and Tianjing budding stage being the latest.Fendou Mulv 2 had the earliest flowering period,and Tianjing had the latest flowering period.Fendou Mulv 2 has the earliest full flowering period,and Tianjing has the latest full flowering period,but both can be used for green manuring and water-logged compost at the end of August.There was a large difference in the yield of fresh grass at the peak flowering stage,and the fresh yield of Tianjing inoculated with rhizobia was the highest,and the nutrient content of nitrogen,phosphorus and potassium in Jufeng and Zheng 1307 plants was the best.The nutrient accumulation of nitrogen,phosphorus and potassium was the highest in Tianjing inoculated with rhizobia.Inoculated with rhizobia can reduce soil temperature and increase soil moisture.Increasing soil stability and wind erosion resistance can improve soil fertility.The preferred variety of summer green manure in rotation with winter wheat was preliminarily screened out as Tianjing(inoculated with rhizobia).
