Root-promoting and yield-increasing plant growth regulator and application

The invention relates to the field of agricultural fertilizers, in particular to a root-promoting and yield-increasing plant growth regulator and application. The growth regulator comprises an activecomponent A, an active component B and an active component C. The active component A is 2-(3-oxo-2-pentyl cyclopentyl)acetyl(2,4-dimethoxy)aniline, the active component B is naphthylacetic acid, the active component C is compound sodium nitrophenolate, and the mass ratio of the active component A to the active component B to the active component C is (1-100):(10-1000):(100-10000). The plant growthregulator composition is more remarkable in effect compared with a single agent, the crop root system development and crop growth can be promoted, the crop yield can be increased, and the crop fruitquality can be improved. 本发明涉及农业肥料领域，具体而言涉及一种促根增产的植物生长调剂及应用。生长调节剂活性成分为活性成分A、活性成分B和活性成分C；所述活性成分A为2-(3-氧代-2-戊基环戊基)乙酰(2,4-二甲氧基)苯胺，活性成分B为萘乙酸，活性成分C为复硝酚钠；其中，活性成分A：活性成分B：活性成分C的质量比为：1-100：10-1000：100-10000。本发植物生长调节剂组合物与单剂相比，效果更为显著，可促进农
