试验针对我国南方地区频频发生的季节性干旱灾害气候,在江西省双季稻种植区,以双季晚稻为研究对象,研究了农业抗旱节水用多功能拌种剂与同类产品(蓝精灵、生根壮秧剂)对提高水稻秧苗素质影响的对比,及其节水增产的应用效果。结果表明,与蓝精灵和生根壮秧剂相比,农业抗旱节水用多功能拌种剂能够更加有效的矮化株高、增加茎粗、提高叶龄、增加根条数和根长、提高根干物质重;使用农业抗旱节水用多功能拌种剂较未拌种处理增产8.47%,节水18.18%,水分利用效率提高32.03%。
In order to study the seasonal drought disasters frequently occurring in the south of our country, we studied the double-season late rice as the research object in the double cropping rice planting area of Jiangxi Province, studied the effects of multifunctional seed dressing and similar products (such as Smurf, Rooting strong agent) to improve the quality of rice seedling quality comparison, and its application of water saving and yield increase. The results showed that, compared with the Smurf and rooting seedling agent, the multi-functional seed dressing for agricultural drought-resistance and water-saving could more effectively reduce plant height, increase stem diameter, increase leaf age, increase root number and root length, Root dry matter weight. The multi-functional seed dressing with agricultural drought-resistance and water-saving increased 8.47%, 18.18% and water use efficiency by 32.03% compared with that without seed dressing.
