Polymer material is a multi-phase composite system with polymer as the main body, that is, few products are made of pure polymer, and most of them are used together with Polymer Additives. The purpose of adding polymer Additives is: 1. to meet the performance requirements; 2. to meet the molding requirements; 3. to meet the economic requirements. Polymer additives include plasticizers (DBP, DOP), phosphate esters (TCP trimethylphenyl phosphate), aliphatic dicarboxylic acids, lubricants, heat stabilizers, processing aids, reinforcing agents, toughening agents, curing agents, antioxidants, light stabilizers, fillers, solvents, foaming agents, and resistances. Propellant, coupling agent and antistatic agent.

First, preferred, appropriate dilute, grading rearing. The fish species will be screened and different fish species will be selected. The fish species of 16.5 cm to 23 cm were placed in a pond for adult fish production; the fish species of 6.6 cm, 9 cm, and 12 cm were individually diluted and intensively cultivated. For ponds with a depth of 1.5 meters, 3000 to 6000 tails per 667 square meters are appropriate.
Second, ensure adequate feed, carefully reared. In addition to fertilizing the water and fertilizing the fish to ensure proper water and good water quality, the fish ponds, which are mainly squid and squid, should also be fed with timely and appropriate amounts of concentrated feed. Usually, they are fed at about 9:00 and 16:00. , rice noodles, distiller's grains, vegetable oil cakes, bean cakes, cotton cakes, etc., for each 1,000 fish species, each feeding 0.3 ~ 0.5 kg. Grass-fish-based fishing ponds should be fed with green materials such as duckweed, aquatic plants, and dry grass, and then fed with fine material to avoid competing for food.
Under conditions permitting, it is best to use artificial grain bait or puffed bait.
Third, strengthen the fine management, pay attention to disease prevention and treatment. During the period of intensive cultivation, the fish species should adhere to the daily patrol ponds, perform detailed management, observe the eating and feeding conditions of the fish, and observe the changes in the water quality. The groundwater should be added or changed frequently. Usually, the new water is added in 7 to 10 days. , each 10 to 20 cm. For grass-fish-based fishing ponds, we must keep the water fresh, remove debris and other materials in time, and often wash the food table. About half a month, we must disinfect the food table with bleach, and regularly use bleach, copper sulfate and other drugs around the food market. Hang bags, hang baskets, prevent fish diseases, find diseased fish, dead fish, timely remove and check, treat the disease, and treat them to ensure a good harvest.
Small size fish species intensified cultivation in late autumn
Whether it is a large area of ​​ponds, banks, rice fields, or intensive fish farming, the size and physical strength of fish species are directly related to the next year's adult fish production. Therefore, fish species must be screened, classified, and taken measures for intensive cultivation in the late fall season to meet the requirements of adult fish production. The post-autumn cultivation methods for small-scale fish species are described below.
