Use of purslane in fishery

With purslane feeding fish, fish love to eat, easy digestion and absorption, fish healthy growth, for this, special introduction of purslane cultivation methods.

First, the cultivation characteristics of purslane. Purslane for human consumption, also known as longevity food, is an annual succulent herb, has wild in all parts of the country, hills and mountains suitable for growth, fast growth, high yield. Purslane is characterized by high humidity, drought tolerance, strong adaptability and vitality, and has the concept of "sun is not dead". The germination temperature is above 20°C, the optimum temperature is 25-30°C, and the optimum temperature for plant growth is 20-30°C. With the increase of temperature, the growth and development are accelerated, the soil requirements are not strict, and nitrogen fertilizers should be used in cultivation. And ensure moisture supply.

Second, the cultivation method of purslane. The purslane cultivation can be divided into roots, layers and seed propagation, transplantation of wild seedlings.

1, split the roots to reproduce. Use mature and old plants to breed, and split them from the base of the branches. Each branch must carry fibrous roots. After drying, the plants can be planted. The distance between the rows is 20 cm and 10 cm. After the planting, the soil is filled with water, and it can be 3-5 days. Slow seedlings, then top-dressing watering, promote its long.

2, layering. The strips with longer peripheries of the mother plants were used as the tamping strips. Each 4-5 cm was piled with wet earth to form a small mound of 4-5 cm in diameter. Leave 3-4 knots in front of the mound, and the upcoming part of the ground, after the branches under the mound is rooted, can be separated from the mother plant to form an independent plant seed.

3, seed breeding. Leave the seedlings and wait for their flowering results. When the fruit has not been opened, harvest the seed. If the fruit is opened, the black seed will fall on its own. Seed sowing after the night frost period. Soil fertigation applies 2,000 kg of farmyard fertilizer and 50 kg of superphosphate per 0.067 ha of land. After watering and hoeing, artificially plowing 15 cm, shredding and squeezing it to make a width of 1-1.2 meters. Flatten the sorghum surface, and open the seeding ditch with a distance of 20 cm, a width of 23 cm, and a ditch depth of 1 cm on the sorghum surface. Mix the seed with 5-10 times fine sand and evenly spread it into the ditch. The soil covers the seed. If the soil is dry, use a watering can to dive in water. You can also sprinkle seeds on the surface of the planter, cover the soil after sowing, lightly press on the surface of the soil, and cover with a thin layer of moisture-retaining straw. Use 500 grams of seed per 0.067 hectare. When the temperature and humidity are appropriate, 2-4 days after sowing. Can emerge.

4. Collect wild seedlings for planting. After the valley rain, the purslane seedlings will be grown in the alluvial soil of hilly mountainous regions. The purslane seedlings with green leaves and stout stalks will be selected. Artificial mulberry seedlings will be used for excavation, with more soil and less roots to facilitate early planting. Fast hair.

5. Strengthen fertilizer and water management. No matter what kind of cultivation method, after 7-10 days of planting, when the seedlings turn green, they can start to top-dressing. Every 15-20 days, every 56.7 hectares of urea is used for 5 kg, water is added for 3000 kg, or biogas. Fertilizer 300-500 kg ensures that the seedlings thrive.

Third, use

1, high-quality feed. Purslane has high nutritional value. According to the determination, per 100g of dry purslane contains 2.3g of protein, 0.5g of fat, 3g of carbohydrate, 0.7g of crude fiber, 85mg of calcium, 56mg of phosphorus, 2.32mg of carotene, Thiamine 0.03 mg, riboflavin 0.11 mg, nicotinic acid 0.7 mg, ascorbic acid 2.3 mg and rich in vitamins are used to feed fish, eat fish, easily digested and absorbed, and fish grow well.

2, health care function. Purslane contains a certain amount of norepinephrine, dicarboxyphenylethylamine, and dicarboxyphenylalanine. These substances have heat-clearing and detoxifying effects. The fish can kill pathogenic bacteria in the body and inhibit the reproduction and invasion of pathogenic bacteria. Dyeing, it has a certain therapeutic effect on fish gut, at the same time, purslane has detoxification, loose blood, swelling, stop phlegm, stop bleeding, anthelmintic effect.

3, use methods. The purslane can be directly fed into fish ponds to feed fish. In order to increase the efficiency of utilization, for each 0.067 hectare of fish ponds, 5 kg of thick and young purslane can be used. After beaten with a beater, add appropriate amount of water to boil for 10-15 minutes. Knead into a pellet, cool and put it in the food table for fish consumption. If the fish has enteritis, enteritis disease cures after 2-3 days of feeding.

Fourth, the effectiveness of fish farming. When feeding fish, it is often used together with appropriate amount of purslane to ensure that fish have enough nutrients and can promote the digestion and utilization of other feeds, thereby promoting the growth of fish, enhancing physical fitness and disease resistance, and expanding the new aquaculture industry The feed source. The use of purslane as feed for fish farming is an effective way to increase aquaculture production, reduce production costs, and increase economic efficiency.
