中文摘要:
      为探明杂交晚稻可降解秧盘育秧所需的适宜播种量,以杂交晚稻品种‘天优华9’为材料,设置每盘干种60,70,80 g 3个播种量水平,展开试验。结果表明,不同的播种量对可降解秧盘育秧的秧苗素质具有显著影响,供试水稻的叶龄、单株根数、倒二叶SPAD值、苗茎基宽、苗干重等随着播种量的增加均降低,株高增加,叶、茎、穗的干物质量和收获指数减小;播种量越少,根系生长速度越快,分蘖早发,70 g/盘最高分蘖数和有效分蘖多;不同播种量育秧对水稻的穗粒数、千粒重和结实率各处理间差异较小,播种量为60 g/盘和70 g/盘的实际产量分别比80 g/盘增产237.75 kg/hm2和228.15 kg/hm2,增产率分别为2.97%和2.85%。综合考虑各指标结果,杂交晚稻可降解秧盘育秧的最适播种量为60 g/盘。该研究结果可为南方双季杂交稻机插育秧技术提供理论基础和技术支撑。
英文摘要:
      To investigate the optimum sowing rate for biodegradable tray of hybrid late rice, using‘Tianyouhua 9’as the test material, the research was conducted with the sowing rate of 60, 70 and 80 g/tray. The results indicated that the sowing rate had significant effect on the quality of seedlings raised by biodegradable tray. With sowing rate increasing, leaf age, the number of root per plant,SPAD of penultimate leaf, stem width and the dry weight of seedling decreased; plant height increased; the dry matter amount of leaf, stem and panicle, as well as the harvest index reduced. The less the sowing rate, the faster the roots grew; the earlier the tillering was. The treatment of 70 g/tray had the maximum tiller number and effective tillers. With different sowing rates, the difference between grains per panicle, 1000-grain weight and seed setting rate was not obvious. The yield of 60 g/tray and 70 g/tray increased by 237.75 and 228.15 kg/hm2, respectively, compared with that of 80 g/tray, and the growth rate was 2.97% and 2.85% , respectively. Taken together, the optimum sowing rate for biodegradable tray of hybrid late rice is 60 g/tray.
