为完善盘锦稻区机插水稻精确定量栽培技术体系,探讨机插秧高产适宜播量。以盐丰47为供试材料,采用小区对比试验,通过设置不同播量处理,测定不同播量对水稻群体生长发育和产量的影响,结果表明,播量为97.5 g/盘的B3处理秧苗素质最好,本田群体生长量适宜,齐穗期和成熟期干物质产量最大,实际产量最高为10.95 t/hm2,比B2、B4、B1、B5处理分别高3.01%、5.80%、8.96%、12.77%。
In order to improve the precise and quantitative cultivation technology system of rice planting in Panjin rice planting area, Using salt abundance 47 as test material, the plot comparison experiment was conducted to determine the effects of different sowing rates on the growth and yield of rice population by setting different sowing rates. The results showed that the quality of B3 seedlings treated with sowing rate 97.5 g / The best Honda population had the most suitable growth and the highest dry matter yield at full heading and maturity. The actual yield was 10.95 t / hm2, which was 3.01%, 5.80%, 8.96% and 12.77 higher than that of B2, B4, B1 and B5, respectively %.
