Description

Aquatic weed carrier, its preparation method and special agar solution

Technical Field

The invention relates to the technical field of ecological breeding, in particular to a waterweed carrier, a manufacturing method thereof and a special agar solution.

Background

The existing aquatic weed production mode is to wrap the aquatic leaves or the aquatic leaves of aquatic weeds with asbestos or aquatic weed mud, and then put the aquatic leaves or the aquatic leaves into a special aquatic weed cup for sale. This mode of production has a number of disadvantages. For example, after the consumer purchases the aquatic weed, the aquatic weed mud or the aquatic weed cup needs to be removed, the aquatic weed, especially the aquatic weed root, which is very important for the growth of the aquatic weed, can be seriously damaged, and the damage of the aquatic weed root can directly cause the death of the aquatic weed. In addition, when the aquatic weeds are transplanted into the aquarium of the consumer, the aquatic weeds are not suitable for a new environment and die due to large environmental change difference and poor adaptability of the aquatic weeds. In addition, after asbestos, float grass or float grass is removed, nutrients are not provided, and float grass can die. In addition, the product of the production mode needs the consumers to have rich processing and planting experiences and perfectly control the planting conditions, density and other factors of the aquatic weeds, which also increases the difficulty for the planting of the consumers. If the production process is infected with pathogenic bacteria or parasites, the consumer's own aquarium is also directly affected. In addition, the method also has the disadvantages of inconvenient transportation, export and the like.

In addition, for epiphytic aquatic weeds, another mode of planting and selling by using carriers such as stainless steel mesh sheets, wood, stones and the like is provided. For example, Moss is stirred and broken, then spread on a stainless steel mesh, and then bound and fixed by fine fish wire until it grows. The production mode of using wood or stone is to bind and fix the epiphytic aquatic weeds on the stone wood by using fish wire or cotton thread, maintain the aquatic weeds in a greenhouse under a long-term spraying high-humidity environment, enable the aquatic weeds to grow leaves adapting to the environment and roots attached to a carrier, and then take the aquatic weeds to market for sale. However, the product also has the problems that the treatment of consumers is complicated, the aquatic weeds are not easy to use in a new environment, and the like. In addition, the carrier can not provide nutrient substances for the aquatic weeds at all, and is not beneficial to the growth of the aquatic weeds. Moreover, the method has large limitation and can only be applied to epiphytic aquatic weeds.

Therefore, the invention is especially provided for facilitating the planting of consumers, accelerating the aquatic weed to adapt to new environment and improving the survival rate of the aquatic weed.
