为探索化学氮肥减量配施条件下双季稻田较优的绿肥混作方式,以早稻品种中早39和晚稻品种泰优390为材料,于2016-2017年采用定位试验研究了不同绿肥混作方式（紫云英单作,AS;紫云英与满园花混作,AR;紫云英与黑麦草混作,AL;紫云英与满园花与黑麦草混作,ARL;冬闲处理,CK）与氮肥减量配施对双季早、晚稻产量形成特性的影响。结果表明:各绿肥还田处理绿肥替代化肥氮比例,2016年为28. 98%～39. 68%,2017年为30. 55%～39. 47%,以AS处理较大,AL处理最低。绿肥替代部分基施化肥对水稻分蘖动态无显著影响,但各绿肥还田处理均有较好的增产效果,不同模式间差异明显,2016年早、晚稻均以AS处理增产效果最好（分...

To probe the optimal green manure mixed cropping modes under condition of chemical fertilizer reduction,the effects of different green manure mixed cropping modes(Astragalus smicus monoculture,AS;Astragalus smicus + Ro-phanus sativus L.mixed cultivation,AR;Astragalus smicus + Lolium perenne L.,AL;Astragalus smicus + Ro-phanus sativus L.+ Lolium perenne L.mixed cultivation,ARL;Winter fallow,CK) and nitrogen reduction application on yield formation characters of early and late rice were studied with Zhongzao 39 and Taiyou 390 as early and late rice materials,respectively.The results showed that:...
