Abstract

The invention belongs to the technical field of algal inhibition, and particularly discloses an algal inhibition material and application thereof in soilless culture. The algal inhibition material is nanoparticles, and the raw materials comprise plant polyphenol, metal ions, a first auxiliary agent and a second auxiliary agent. According to the algae inhibition material and the application thereof in the soilless culture, on the basis that an existing large-scale soilless culture technology is not changed, original components of the hydroponic nutrient solution are not damaged, the algal inhibition material which is environmentally friendly, high in selectivity, short in residual time and universal for various algae is provided, the problem that the hydroponic nutrient solution is harmful to the algae in the soilless culture technology is solved, the use of pesticides and secondary pollution are reduced, the damage to cultured plants is reduced, and the light transmission of the hydroponic nutrient solution is kept; and meanwhile, the material can be used as the algae inhibition material for effectively preventing the growth of algae in the hydroponic nutrient solution and mainly realizing prevention. Implementation of the algal inhibition material has important practical significance on improvement of soilless culture agricultural planting efficiency, saving of water resources, reduction of secondary pollution, reduction of labor intensity and improvement of economic benefits.

Description

technical field [0001] The invention belongs to the technical field of algae inhibition, and in particular relates to an algae inhibition material and its application in soilless cultivation. Background technique [0002] Soilless cultivation of vegetables and fruits, allowing multi-level production of fruits and vegetables, obtaining more space value and reducing land demand is one of the directions of agricultural development in my country at present. The main feature of soilless cultivation technology is that the multi-layer space planting, the yield is much higher than the traditional soil cultivation, completely separated from the attachment to the soil, thus eliminating the tedious work of land treatment, and can also greatly reduce the labor force. In addition, the industrial production mode of soilless cultivation is a self-circulating closed system, which can reduce the use of chemical fertilizers, pesticides (insecticides, herbicides, etc.), water resources, etc., ...
