Abstract

The invention provides a nutrient solution suitable for hydroponic medicinal cannabis sativa, and application thereof. The nutrient solution comprises a solution A and a solution B; the solution A comprises potassium nitrate, monopotassium phosphate, magnesium sulfate, manganese sulfate, borax, copper sulfate, zinc sulfate and sodium molybdate; and the solution B comprises calcium ammonium nitrate, EDTA, EDDHA, fulvic acid, compound amino acid and a trace additive. The nutrient solution suitable for hydroponic medicinal cannabis sativa can obviously improve the yield of floral leaves and the stability of the content of medicinal components.

Description

technical field [0001] The invention belongs to the technical field of hemp cultivation, and in particular relates to a nutrient solution suitable for hydroponic medicinal hemp and an application thereof. Background technique [0002] Industrial hemp, also known as hemp, refers to hemp varieties with a tetrahydrocannabinol (THC) content of less than 0.3%. In China, the use of industrial hemp involves fields such as health food, medicine, textiles, building materials, and papermaking. According to the National Bureau of Statistics, the total output value of industrial hemp in my country was about 7.5 billion yuan in 2017, of which textile fibers accounted for 76%, food accounted for 7%, and medicinal products accounted for only 5%. Cannabidiol (CBD) is one of the main chemical components in medicinal industrial hemp. Unlike THC, CBD not only has no hallucinogenic effect, but also has a variety of pharmacological effects on the nervous system, and has great application value...
