摘要 超级稻新品种松粳15为研究对象,以松粳9为对照,设置4个栽培密度和5个施肥水平处理,分别对有效穗数、实粒数、瘪粒数、穗长和千粒重等农艺性状及干物质质量、叶面积指数开展调查,探讨松粳15的最适栽培技术条件及高产机理。结果表明,松粳15在栽培密度为30 cm×13.2 cm,施纯氮13 kg·(667 m^(2))^(-1)条件下产量最高。对不同肥力下各生育期的干物质和叶面积指数进行分析,表明松粳15能够在抽穗期和灌浆期保持较高的叶面积指数和SPAD值,极大地增加了干物质积累量,并为产量提高奠定基础。 In this paper,the Songjing 15,a new super rice variety identified by the Ministry of Agriculture and Rural Affairs,and Songjing 9 were selected as the research object and as the control material respectively,4 cultivation densities and 5 fertilization levels were set to investigate the agronomic traits including effective panicle number,solid grain number,flat grain number,panicle length and 1000-grain weight,dry matter mass and leaf area.And,the optimum cultivation conditions and high yield mechanism of Songjing 15 were also discussed.The results showed that Songjing 15 had the highest yield under the cultivation density of 30 cm×13.2 cm and pure nitrogen application of 13 kg·(667 m^(2))^(-1).The analysis of dry matter mass and leaf area index(LAI)at different growth stages under different fertility showed that Songjing 15 could maintain high LAI and SPAD values at heading stage and grain filling stage,which greatly increased the dry matter accumulation and laid the foundation for the increase of yield.
