The invention provides a plant growth synergist containing polyglutamic acid, and relates to the technical field of agricultural production. The plant growth synergist containing polyglutamic acid comprises the following raw materials in percentage by weight: 0.01 to 2.0 percent of gamma-polyglutamic acid, 0.1 to 30 percent of bactericide, 0.001 to 0.5 percent of plant growth regulator, 1 to 20 percent of polyphosphate and 47.5 to 98.889 percent of auxiliary material component. The compound use of the bactericide and the plant growth regulator can prevent and treat soil-borne diseases in soil and achieve a protection effect, the brassinolide belongs to a steroid compound, the plant growth can be promoted, the phytotoxicity of the bactericide to plants can be reduced, the gamma-polyglutamic acid has water retention and water absorption in the soil, water and effective components can be well locked, the loss of the bactericide, the plant growth regulator and nutritional components can be reduced, the polyphosphate is a slow-release phosphorus-potassium fertilizer, has a complexing effect, can complex the bactericide and the plant growth regulator, has a slow-release effect, and can increase the duration. |
