Abstract

The invention provides a vegetable hydroponic nutrient solution containing amino acids as well as a preparation method and application thereof, and belongs to the field of plant growth. The inventionprovides the organic and inorganic composite nutrient solution, which breaks through the conventional pure inorganic mineral nutrient solution and is supplemented with organic components such as aminoacids. The disclosed hydroponic nutrient solution contains compound amino acids, has the fertilizer efficiency higher than that of simple substance amino acids, and has the effects of strengthening root systems, promoting greening, increasing tillering and improving stress resistance, thereby improving the crop yield. The amino acids have a special promotion effect on root development of crops,can be directly absorbed by a root system in a complete molecular form and can be assimilated in crop bodies through transamination, deamination and other processes to synthesize protein or form metabolism energy, and form organic acids, carbohydrate and other nutrients; in addition, amino acids can promote the activity of nitrate reductase in crop leaves, and meanwhile, the amino acids are used as a nitrogen source to partially replace nitrate, so that the content of nitrate in crops can be reduced, and the quality of the crops can be improved.

Description

technical field [0001] The invention relates to the technical field of plant growth, in particular to an amino acid-containing vegetable hydroponic nutrient solution and a preparation method and application thereof. Background technique [0002] Nutrient solution is a key technology in hydroponic planting, which plays a decisive role in the growth of vegetables. The state of the root system reflects the growth trend of vegetables. General hydroponic fertilizers are completely mineral and inorganic nutrients, which have a weak effect on promoting root growth. In order to blindly pursue rooting, some fertilizer manufacturers add hormone rooting agents, which deviates from the concept of food safety. Moreover, the nitrogen in pure inorganic fertilizers is mainly nitrate, and the nitrate content of hydroponic vegetables is relatively high. After being ingested by the human body, nitrite will be generated through denitrification, which is not conducive to health. The above prob...
