摘要
采用大区对比试验方法,研究了印刷播种方式下机插水稻光合物质生产及产量特征。结果表明,与常规播种方式相比,印刷播种方式能提前水稻播种期,延长总生育期;提高机械栽插群体起点质量,优化群体结构,促进个体生长发育,增大成熟期群体干物质积累量;通过足穗、大穗,攻取较高群体颖花量,稳定结实率和千粒重;能显著增加水稻产量5%以上。其中在印刷播种方式下,机械栽插时增大秧爪抓秧量,可提高田间基本苗的同时进一步增加水稻产量。
Field experiments were conducted to explore the characteristics of yield and photosynthetic matter production of mechanical transplanted rice under printing-sowing technology.Results showed that,compared to the conventional sowing method,sowing method with printing-sowing technology could1.advance the rice sowing date and prolong the growth duration;2.improve the seedlings population quality at transplanting date,optimize the population structure,promote individual growth and development,and increase the dry matter accumulation at maturity;3.increase the total spikelets with enough panicles and big panicle,and maintain stable seed setting rate and grain weight;4.increase the rice yield by more than5%significantly.In addition,under the sowing method with printing-sowing technology,rice yield could be higher furthermore through increase the field seedling number at transplanting date with larger seedling claws and more catch seedlings.
