- 摘要:
- 为了提高水稻田肥料应用效率,减施增效,提高水稻抗性及产量,本研究采用田间随机区组试验,分别在水稻苗期、生长期、成熟期进行三段式高产化控施肥技术处理和常规施肥处理,比较添加微生物菌剂、纳米硅及磷酸二氢钾的三段式高产化控施肥技术对水稻农艺性状和产量的影响。结果表明:三段式高产化控施肥技术通过添加微生物菌剂、纳米硅肥及磷酸二氢钾比常规施肥处理显著提高了水稻分蘖数、叶绿素值、叶面积、根长、千粒重、有效穗数和穗粒数,水稻倒伏面积比降低了82.15%,产量提高了6.74%,出米率提高了7.66%。
- Abstract:
- In order to improve the application efficiency of fertilizer in rice field,reduce fertilizer application and increase efficiency,and improve rice resistance and yield,a field randomized block experiment was conducted to carry out three-stage high-yield chemical controlled fertilization and conventional fertilization at rice seedling stage,growth stage and mature stage,effects of three-stage high-yield chemical controlled fertilization technology of nano silicon and potassium dihydrogen phosphate on agronomic characters and yield of rice.The results showed that the three-stage high-yield chemical controlled fertilization technology significantly increased the number of tillers,chlorophyll value,leaf area,root length,1 000 grains weight,effective panicles and grains per panicle of rice by adding microbial agents,nano silicon fertilizer and potassium dihydrogen phosphate.The lodging area ratio of rice decreased by 82.15%,the yield increased by 6.74% and the rice yield increased by 7.6%.
