Additive of soilless culture nutrient solution

Abstract

The invention discloses an additive of a soilless culture nutrient solution. The additive comprises the following materials in parts by weight: 35-60 parts of wood vinegar, 40-75 parts of polyhexamethylene guanidine, 10-35 parts of zinc gluconate and 5-18 parts of glucoamylase. The soilless culture nutrient solution can be rapidly sterilized by selecting polyhexamethylene guanidine as a sterilizing agent. Wood vinegar can provide multiple fertilizer efficiency and trace elements. Zinc gluconate can achieve the antiseptic effect. Glucoamylase can conduce to promoting plants to absorb nutrients and reducing diseases. Compared with the prior art, the additive has the obvious advantages that the additive is capable of rapidly eliminating diseases and thoroughly sterilizing the nutrient solution; the additive is capable of supplying nutrients to the nutrient solution and promoting the plants to rapidly absorb nutrients; the product is stable and has long shelf life.

Description

technical field [0001] The invention relates to an additive for a soilless culture nutrient solution, belonging to the technical field of sterilizing agents. 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...

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.
