Breeding leeches (also known as leeches) requires selecting suitable sites to ensure their healthy growth and reproduction. The following is a detailed analysis of the required site for breeding locusts: 1. Basic requirements for the site
1. Water conditions: Grasshoppers are aquatic animals, so there needs to be a water source near the breeding site, such as lakes, rivers, streams, ponds, reservoirs, irrigation canals, etc., and the water depth should preferably be at least 1.5 meters. At the same time, the water quality should be kept as clean as possible, the dissolved oxygen content should be appropriate, the pH value should be between 6 and 5, the ammonia nitrogen should not exceed 0.1mg/L, the nitrite should not exceed 0.005mg/L, and the dissolved oxygen should be above 3.0mg/L. If the pool water has a special odor or rotting smell, it should be replaced or the pool should be emptied and cleaned in a timely manner to prevent a large number of leeches from dying.
2. Warm environment: Grasshoppers prefer warm environments, and it is best to keep the water temperature between 20 ° C and 30 ° C. Spring and autumn are the active periods for the growth of locusts, while in winter when the temperature drops below 10 ° C, locusts will stop feeding and hibernate in the soil. The breeding site should be selected in a sheltered and well lit area to meet the growth needs of the leech, and cold prevention measures should be taken in winter.
3. Quiet place: Grasshoppers prefer quiet environments, so breeding grounds should be away from noisy sources such as factories, roads, etc. 2、 Specific selection of venue
1. Reservoir aquaculture: Reservoirs usually have large water areas and abundant aquatic resources, suitable for the growth of locusts. But attention should be paid to the changes in water level and water quality management of the reservoir.
2. Pond cultivation: Pond cultivation of grasshoppers requires selecting ponds with good water quality and convenient drainage and irrigation. At the same time, it is necessary to regularly clean the debris and sediment in the pond to maintain clean water quality.
3. Swamp farming: Swamp areas have a high content of organic matter and humus in the bottom layer, and are rich in plankton and aquatic animals, making them suitable for the growth of grasshoppers. But it is necessary to pay attention to the changes in water level and water quality management in the marshland, and at the same time, it is necessary to build fences to prevent locusts from escaping.
4. Rice field farming: Rice fields have the characteristics of shallow water level, suitable water temperature, and abundant feed, which are suitable for the growth and reproduction of grasshoppers. However, attention should be paid to factors such as convenient drainage and irrigation, sufficient water sources, and soil moisture retention and fertility in paddy fields. 3、 Site planning and construction
1. Site planning: Reasonably plan the size and layout of the breeding site based on the scale of breeding and the amount of funds. At the same time, it is necessary to consider the construction of breeding ponds, the division of functional areas such as feed storage and processing zones, and disease prevention and control zones.
2. Construction of aquaculture ponds: Aquaculture ponds can be constructed in the form of cement ponds or soil ponds, but attention should be paid to the anti-seepage and drainage performance of the ponds. At the same time, shading facilities need to be installed to regulate water temperature, and oxygenation equipment needs to be installed to increase the dissolved oxygen in the water.
3. Fence construction: In order to prevent locusts from escaping and natural enemies from invading, fences need to be built around the breeding site. The height and density of the fence should be determined based on the body size and habits of the grasshopper.
Breeding locusts requires selecting suitable sites and planning and constructing breeding facilities reasonably. At the same time, attention should be paid to water quality management, temperature control, feed feeding, and disease prevention and control to ensure the healthy growth and reproduction of locusts.
