Inert matrix in aquaponic system

Abstract

The invention relates to an inert matrix in an aquaponic system. The inert matrix comprises the following ingredients in percentage by weight: ceramsite (40-70%), vermiculite (30-50%) and seaweeds (10-30%). The porous structure of the ceramsite can cause microorganisms to form bacterial colonies, the vermiculite contains microelements such as calcium, magnesium and iron, which just can supplementelements that the aquaponic system lacks, whereas the seaweeds are rich in various kinds of nutrient elements and can serve as an excellent seedling growth matrix, entire transplantation can be performed as well when the ceramsite, the vermiculite and the seaweeds are combined, and damage to the root system of a plant in the traditional transplantation process is avoided.

Description

technical field [0001] The invention relates to the field of facility agriculture, in particular to an inert substrate in an aquaponics system. Background technique [0002] Aquaponics is a new type of compound farming system, which belongs to soilless hydroponics during planting, while the traditional seedling raising method using nutrient soil or other substrates will lose the growth cycle of plants for 4-5 days. At the same time, aquaponics Among them, because its nutrient source is relatively single, it is easy for plants to lack trace elements such as iron, potassium, calcium, etc., and iron is the main raw material for the synthesis of chlorophyll in plants. Iron deficiency can easily lead to chlorosis between plant veins, especially young leaves, which are light yellow. Even whitish. Contents of the invention [0003] Based on the above situation, the inert substrate in the aquaponics system of the present invention, in addition to the traditional role of fixing th...
