Soilless culture nutrient solution

Abstract

The invention discloses a soilless culture nutrient solution which comprises the following components in parts by weight: 85-115 parts of wood vinegar, 25-45 parts of urea humate, 20-40 parts of potassium metaphosphate, 15-30 parts of disodium octaborate tetrahydrate, 10-25 parts of zinc sulfate, 10-20 parts of magnesium chloride and 2000-2300 parts of pure water. The wood vinegar, which is used as the formula component, is a pure natural substance which is distilled out from perennial oak by high temperature, contains K, Ca, Mg, Zn, Ge, Mn, Fe and many other minerals, contains more than 200 organic matters, including phenols, acids, alcohols, ketones and the like, also contains vitamins B1 and B2, is a system substance with complex composition, multiple functions and relatively high stability, and has the functions of plant growth promotion, disinfection, sterilization, moth and corrosion resistance and the like.

Description

technical field [0001] The invention relates to a soilless culture nutrient solution, which belongs to the technical field of fertilizers. Background technique [0002] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The nutrient solution is a new type of nutrient solution synthesized by using the environmental biological ecological symbiosis technology and the principle of mycorrhizal symbiosis through biological fermentation, chemical chelation, physical activation and other processes. Nutrient solution is the key to soilless cultivation, and different crops require different nutrient solution formulations. The plant nutrient solution is generally a multi-component compound nutrient, which is in the form of water....

Problems solved by technology

The nutrient solution is generally used every 10 to 15 times. If the nutrient solution is left standing for a long time, many bacteria and viruses will often breed, which will endanger the health of plants.
