| 中文摘要: |
| 为探索适宜的稻茬小麦栽培模式，基于本课题组近13年的田间试验数据，分析了播期、基本苗和肥料运筹对稻茬小麦产量及经济效益的影响，进而构建不同高产栽培模式，并比较其高产、稳产、节本增效的能力。结果表明，适播（10月29日-11月4日）条件下稻茬小麦产量、净效益和产投比均显著高于早播（10月17日-10月26日）和晚播（11月6日-11月20日），增幅分别为12%～13%、24%～27%和22%～27%，但不同播期之间的投入差异不显著。在适播条件下基本苗和施氮量、晚播条件下基本苗与产量和净收益均呈抛物线关系。适播基本苗210×10～240×10株·hm-2和施氮量180~225 kg·hm-2、晚播基本苗240×10～270×10株·hm-2和施氮量240～270 kg·hm-2构建的高产模式下产量分别达8.21和7.46 t·hm-2 ，这两种模式均具有高经济效益和低投入特点，在不同年度、地点和品种下稳产性好。 |

| The main aim of this study is to provide a reference to wheat production for high yield,stable production,low cost,and high efficiency in rice-wheat rotation system. The experimental data of 13 years on wheat production in rice-wheat rotation system was collected,to analyze the effects of sowing date,seedling rates and fertilization application on grain yield and economic efficiency,and then to establish different high-yield cultivation modes. Furthermore,the capacities of high yield,stable production,low cost,and high efficiency were compared between/among these modes. The grain yield, economic income and input-output ratio under the condition of suitable sowing （October 29 to November 4）was 12%-13%,24%-27% and 22%-27% higher than those under the condition of early sowing (October 17 to October 26)and late sowing(November 6 to November 20). But there was no significant difference among different sowing dates. There was a parabola function relation between seedling rates and nitrogen rates under the condition of suitable sowing,and a parabola funvtion relation between seedling rates and grain yield and economic income under the condition of late sowing. According to the analyses,the high-yield modes with seedling rates 210×10-240×10 plants·hm-2 and nitrogen rates 180-225 kg·hm-2 under the condition of suitable sowing,and with seedling rates 240×10-270×10 plants·hm-2 and nitrogen rates 240-270 kg·hm-2 under the condition of late sowing were respectively established,which gained the grain yield of 8.21 and 7.46 t·hm-2. Additionally,compared to other modes,these modes showed higher economic income,lower input,and better stable production in different years,locations and varieties. |
