Description
技术领域
本发明属于农药复配技术领域，具体涉及一种植物生长调节剂组合物及其应用。
背景技术
吲哚乙酸是一种常见的植物生长调节剂，可被植物的茎、叶和根系吸收，根据使用浓度不同，发挥作用也有所不同，既可起促进作用，也可起抑制作用。见光易分解。(1)影响细胞分裂、细胞伸长和分化；(2)影响营养器官和生殖器官的伸长、成熟和衰老；(3)用于组织培养中，诱导愈伤组织和根的形成。
在高等植物中几乎所有的器官和组织中均含有赤霉素，赤霉素促进生长具有以下特点：(1)可促进整株植物生长，尤其是对矮生突变品种的效果特别明显；(2)一般促进节间的伸长，不是促进节数增加；(3)对生长的促进作用不存在超最适浓度的抑制作用。
三十烷醇具有促进作物生根、发芽、开花、茎叶生长和早熟的作用，具有提高叶绿素含量、增强光合作用等多种生理功能。在作物生长前期使用，可提高发芽率、改善秧苗素质，增加有效分蘖。在生长中、后期使用，可增加花蕾数、座果率及千粒重。
本专利申请发明人通过深入研究，探索出植物生长调节剂组合物，该组合物在促进作物生长，尤其是提高作物结实率方面表现出协同增效的作用，且该组合物也未出现在已知的文献中，本领域普通技术人员也难以知晓该组合物用于提高作物结实率所产生的有益效果。
