摘要: 以常规迟熟中粳品种南粳9108为材料,在钵育摆栽条件下,设置每丛2苗、3苗、4苗3个处理,研究不同丛基本苗数对钵苗摆栽常规粳稻群体质量及产量的影响,以完善安徽沿江地区“籼改粳”后机插栽培技术。试验结果表明,钵育摆栽栽后缓苗期短,新分蘖增加快,够苗及到达高峰苗期时间短;每丛3~4苗时群体结构合理,中后期群体LAI及物质积累能力较高,群体成穗多,进而促进产量的提高。

Abstract: In order to improve machincal transplanted cultivation technique after “Indica rice to Japonica rice” in the area of Yangtze River of Anhui Province, effects of basic seedling number per hill on population quality and grain yield of bowl transplanted conventional japonica rice were studied. The experiment was conducted with different seedling number per hill(2, 3, 4 seedlings per hill) using an conventional Japonica rice Nanjing 9108 under bowl transplanted. The results showed that the seedling of bowl transplanted turned green very soon and its tillers developed early. It spends very short time to arrive enough seedling and peak seedling stage. The seedling number per hill ranged from 3 to 4 could established a suitable population, and improved LAI and dry matter accumulation ablity in the middle and late growth stage. Moreover, it significantly increased effective spike number of population and grain yield. So, the seedling number per hill ranged from 3 to 4 was suitable for bowl transplanted conventional Japonica rice in the area of Yangtze River of Anhui province.

Key words: indica rice to japonica rice, bowl transplanted, basic seedling number, LAI, dry matter accumulation, yield
