摘要
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%。
Aiming at the frequent occurrence of the seasonal drought disasters climate in southern China,the double cropping rice is selected as the research object to carry out the comparative study on the effects of multifunctional(water-saving and drought-resistant)seed-dressing agent and other similar products,including LanJinglin agent and the rooting seedling strengthen agent,on seeding quality-improving and water-saving and yield-increasing cultivation of rice in Jiangxi Province double-crop rice growing areas.The results show that compared with the LanJinglin agent and rooting seedling strengthen agent,the multifunctional seed-dressing agent can be more effective in dwarfing plant height,increasing the stem width,promoting the leaf age,raising the root number and length and enhancing the root dry weight.Meanwhile,compared with the unused seed dressing treatment,the multifunctional seeding dressing agent can increase yield by 8.47%,save water by 18.18%and raise water use efficiency by 32.03%.
