The selection of aquaculture cages prior to astragalus culture is the key to avoiding the use of network cables made of toxic or hazardous materials and avoiding the use of cages with poor quality and rupture. The cages used to keep the yam are usually made of nylon mesh. At present, there are two types of meshes sold on the market in terms of quality: one is polyethylene, non-toxic, soft, resistant to sun and ice, and durable; the other is polypropylene, toxic and hard , easy to aging, in the sun exposure, the short life. The following describes the purchase and supply of cages for your reference.
There are three ways to purchase polyethylene mesh:
One is to pinch it and find out if it is soft. The second is to use fire, if the burning glue can drop like tears, and there is a strong adhesive ability, while the heat can be drawn into a line of polyethylene. If it becomes ash after burning, or its adhesive ability is small, it cannot be made from polypropylene or other raw materials.
The third is to pull hard, take a piece of mesh silk thread, pull with two hands, polyethylene wire tensile strength, elasticity. Polypropylene wire is easy to be brittle under the tensile force.
At present, there are existing cages for sale. When purchasing, it is best to choose cages that are 3 to 5 meters long, 2 to 2.5 meters wide, and 1.2 to 1.5 meters high. The cages are required to be tightly closed, and thicker pull wires are required around the box mouth.
The selection and production of cages is a key factor in breeding astragalus, and if it is not well controlled, it can also lead to the failure of aquaculture farmers. In order to raise the quality of the yellow cockroach and prevent farmers from making mistakes in raising cockles in cages, the purchase of cages is very important.
