As the saying goes: "If crabs are raised well, they mainly look at aquatic plants." This statement shows the importance of aquatic plants in the Pingtian embankment. Planting aquatic plants in the Pingtian embankment pond will not only benefit the clams of the crabs, but also provide shelter for crabs in the summer heat season, and it can also provide plant foods for detaining crabs and purify water. To prevent diseases, in order to have a good pool of grass, in the entire process of farming crabs, we should pay attention to the following factors that affect the growth of crab ponds for reference:
1, improper use of drugs, affecting the growth of aquatic plants: At present, some deducted crab farmers use a large number of insecticide, killing moss and other drugs, and did not promptly detoxify after use, resulting in water plants stop growing, so that water plants yellow, rot, rotten first phenomenon.
2. Poor environmental conditions in ponds affect the growth of aquatic plants: According to the survey, some farmers used organic fertilizers in the early stage of fertilizer and water processes, resulting in excessive water quality, low transparency, insufficient water in plants, slow metabolism, poor nutrition, and impeded growth. .
3. The increase of harmful substances will affect the growth of aquatic plants: In the middle and later stages of crab farming, the amount of residual baits and excreta at the bottom of the pool will continue to increase. As the temperature continues to rise, the bottoms will stink if the temperature is continuously increased. Layers of low oxygen, poor ventilation, water grass roots are easy to black, withered, decay.
4. The increase of pests and diseases will affect the growth of aquatic plants. The spring and summer season is the breeding season for various diseases and insect pests. Many flying insects will spawn on aquatic plants. The hatched larvae will eat large amounts of plants, making it difficult for aquatic plants to grow.
In addition: in the hot season, the rapid growth of aquatic plants will also affect their own light, causing the water plants to rot due to poor lighting conditions. In short, the growth of aquatic weeds is closely related to pond bottom quality, water quality, light, etc., and they maintain an ecological balance with each other. If any part of a plant has problems, it may affect the growth of aquatic weeds.
