Problems solved by technology

[0003] Because hydroponic plants are planted by soaking the roots of plants in nutrient solution, hydroponic plants mainly rely on nutrient solution to provide plants with water, nutrients, oxygen and other materials. Therefore, hydroponic plants should generally apply special nutrient solution quantitatively, nutrient solution It is formulated according to the nutrient ratio, concentration and pH required by plants. If the nutrient solution is not properly configured, there will be rotten roots and green moss in the water, which will cause the plants to die easily.

Abstract

The invention relates to the technical field of biogas slurry, and discloses a plant hydroponic nutrient solution prepared from biogas slurry and a preparation method, the plant hydroponic nutrient solution comprises the following raw materials by weight: 1-2 parts of main elements, 1-2 parts of secondary elements, 100-150 parts of water, 2-2.5 parts of adjusting elements, and 1-1.5 parts of eliminating elements. According to the invention, main elements and secondary elements are diluted in water, and meanwhile, calcium nitrate, potassium nitrate, magnesium sulfate, monopotassium phosphate, manganese sulfate, magnesium chloride, potassium permanganate, zinc sulfate, copper sulfate and boric acid in the main elements and the secondary elements are absorbed by water, so that the main elements and the secondary elements can supplement elements contained in the water; the water contains richer nutrition, the nutrition of the plants is supplemented, the root systems of the plants are more developed, the plants grow better, and the effect of improving the survival rate of the plants is achieved.

Description

technical field [0001] The invention relates to the technical field of biogas slurry, in particular to a plant hydroponic nutrient solution prepared by using biogas slurry and a preparation method. Background technique [0002] Biogas slurry is a bright brown liquid formed by the fermentation of organic substances, containing various amino acids, vitamins, proteins, auxins, sugars, nucleic acids, and antibiotics. Biogas slurry is mainly used for soaking seeds, spraying fertilizer on foliage, mixing nutrient soil and flower and fruit preservation agents, mother liquor for soilless cultivation, planting flowers, etc. Biogas slurry not only contains rich nitrogen, phosphorus, potassium and other large nutrients and zinc, etc. Micronutrients, and contains 17 kinds of amino acids, active enzymes. These nutrients basically exist in the form of quick-acting nutrients. Therefore, biogas slurry has strong quick-acting nutrient capacity and high nutrient availability. It is a multi-v...
