Composite nutrient solution capable of promoting propagation of crop roots as well as preparation method and application of composite nutrient solution

Abstract

The application discloses a composite nutrient solution capable of promoting the propagation of crop roots as well as a preparation method and application of the composite nutrient solution. The composite nutrient solution comprises an active ingredient and a polar cosolvent, wherein the active ingredient mainly comprises 3-indolebutyric acid, chitin and vitamin C at a weight ratio of (0.1-10) to (0.1-2.5) to (0.1-10). According to the composite nutrient solution disclosed by the application, the active ingredients are matched with one another to sufficiently develop the role, the promotion effect of the propagation of the crop roots is improved, further, strong seedling and disease resistance can be strengthened, moreover, the stress resistance of crops is improved, and finally, the purpose of increasing the crop yield is achieved. According to the composite nutrient solution disclosed by the application, the function of promoting the propagation of the crop roots is good, the use efficiency is high, and the environmental pollution caused by quantity use of the single active ingredient can be avoided while the use cost is lowered.

Description

technical field [0001] The present application relates to the field of agricultural fertilizers, in particular to a compound nutrient solution for promoting root propagation of crops and its preparation method and application. Background technique [0002] The process of plant growth and development is affected by external environmental factors, such as temperature, diseases, etc., and internal genetic factors. In recent years, extreme weather and climate factors have had a significant impact on plant growth, and have increased the number of generations of pests and diseases, seriously affecting the development of agricultural economy. [0003] Modern agriculture uses plant growth hormones to chemically regulate plant physiological and biochemical activities to ensure the process of plant growth and development. Growth regulators are a class of exogenous non-nutritional chemical substances that have similar physiological and biological effects to plant hormones. They can pr...

Problems solved by technology

[0005] At present, the pesticides applied to crops generally only have a single function of fertilizer supplementation, sterilization, and disease resistance. During the growth and development of crops, they are affected by their own physiological diseases and environmental factors, resulting in the high-frequency and large-scale use of single-function pesticides. The cost of fertilization and medicine increases, but the effect is single, and excessive use causes pollution, damages the ecological environment, affects the yield and quality of agricultural products, and affects the economic benefits of farmers
