摘　　要：[目的]通过水稻大田栽培垄向的调整,改善水稻田间环境,协调水稻群体与光照的关系,研究不同垄向栽培对水稻产量的影响。[方法]对南-北垄向、东-西垄向、东南-西北垄向、东北-西南垄向栽培条件下水稻的干物质积累、产量性状及产量进行研究。[结果]综合干重、产量性状和产量等主要数据,龙亢农场水稻东南-西北垄向栽培最佳,有效穗多、千粒重大、产量高,各指标分别为370.5万穗/hm^2、27.1 g、11160 kg/hm^2。[结论]东南-西北垄向栽培方式对水稻高产的获得具有重要研究意义。[Objective]The aim of this study was to improve the field environment of rice,coordinate the relationship between rice population and light,and study the effect of different ridge cultivation on rice yield.[Method]The dry matter accumulation,yield characters and yield of rice were studied under the cultivation conditions of south-north ridge,east-west ridge,southeast-northwest ridge and northeastsouthwest ridge.[Result]According to dry weight,yield characters and yield,the southeast-northwest ridge cultivation of rice in Longkang Farm was the best,with more effective panicles,large 1000 grains and high yield.Each index was 3.705 million panicles/hm^2,27.1 g and 11.160 kg/hm^2,respectively.[Conclusion]The southeast-northwest ridge cultivation was of great significance to the high yield of rice.
