Chinese herbal medicine preparation capable of inhibiting blue-green algae water blooms as well as preparation method and use method of Chinese herbal medicine preparation

Abstract

The invention discloses a preparation method and a use method of a Chinese herbal medicine preparation capable of inhibiting blue-green algae water blooms. The Chinese herbal medicine preparation comprises the following raw materials in parts by weight: 20-50 parts of rhizoma coptidis, 20-50 parts of cortex meliae, 10-20 parts of herba artemisiae annuae, 5-10 parts of semen strychni, 20-50 parts of radix scutellariae, 20-50 parts of cortex phellodendri, 20-50 parts of rhizoma pinelliae, 5-10 parts of radix aconiti lateralis praeparata and 5-10 parts of radix et rhizoma rhei. The Chinese herbalmedicine preparation provided by the invention is rich in allelochemicals, and active allelochemicals including alkaloid allelochemicals, phenol allelochemicals, citrin fatty acid allelochemicals, sesquiterpene diterpenoid allelochemicals, coumarin allelochemicals and flavone allelochemicals in the raw material destroy the structure and the functions of a blue-green algae cytomembrane by influencing the photosynthesis of the blue-green alga, so that the effects of killing the blue-green alga and inhibiting the water bloom phenomenon of the blue-green alga are achieved; the raw materials of the Chinese herbal medicine preparation are natural Chinese herbal medicines, so that the Chinese herbal medicine preparation is safe, efficient, nontoxic and harmless without generating secondary pollution; the Chinese herbal medicine preparation is less in use dosage, high in elimination efficiency to the blue-green algae water blooms and short in reaction time; and the Chinese herbal medicine preparation can be widely applied to the process of inhibiting blue-green algae water bloom growth or treating outbreak of the blue-green algae water blooms.

Description

technical field [0001] The invention relates to the field of water eco-environmental protection management, in particular to a Chinese herbal medicine preparation capable of inhibiting cyanobacteria blooms, a preparation method and a use method thereof. Background technique [0002] Cyanobacteria are an ancient group of prokaryotic organisms with dual characteristics of algae and bacteria. They can use sunlight, water, nitrogen, phosphorus, carbon dioxide and other nutrients for photosynthesis. They are photoautotrophic organisms. Its cells contain a relatively high concentration of algae toxins - microcystin (MC), long-term exposure will damage the liver function of the human body, and also have a certain impact on nerves, cells and skin. The cyanobacteria population is relatively large, but the single cell is very small, with a minimum diameter of only 0.1um. The pseudovacuole in the cell can provide adjustable buoyancy and control its vertical distribution in the water bo...

Problems solved by technology

As early as the early 1920s, when a large-scale outbreak of cyanobacteria blooms occurred in my country, a water hyacinth native to Brazil was introduced. Its roots can secrete N-phenylnaphthylamine, linoleic acid glyceride, acetoacetyl A large number of strong active allelochemicals such as isocyanide and propionamide destroy the algae cell structure, reduce the chlorophyll content, inhibit photosynthesis and kill them. Had to spend a lot of manpower and material resources to salvage and remove, causing secondary pollution to water bodies
