In the pond where lobsters are farmed, fertilized water can not only promote the growth of aquatic plants and provide abundant food for lobsters**, but also regulate water quality and maintain the ecological balance of the pond. So, how to choose fertilizer and water products?The following is introduced from several aspects.
1. Choose the right fertilizer and water products
Organic fertilizer:Organic fertilizer is the most common way to fertilize water, including animal manure, plant residues, etc. The decomposition of these organic substances releases large amounts of nutrients that provide nutrients for the algae while promoting the growth of microorganisms. However, it should be noted that organic fertilizer should be used after full fermentation to avoid diseases and the production of harmful substances such as ammonia nitrogen. In addition, most farmers will choose organic amino acid fertilizer: multi-effect fertilizer water pioneer, rich in a variety of amino acids, trace elements and other nutrients, small molecules are easy to absorb, can be low temperature and rapid fertilizer water.
Inorganic fertilizer:Inorganic fertilizers include chemical fertilizers such as urea and potassium dihydrogen phosphate. These fertilizers have a single nutrient and fast fertilizer efficiency, but excessive use will lead to eutrophication of the water body and affect the growth of crayfish. Therefore, the amount of inorganic fertilizer should be strictly controlled, and the principle of small amount and many times should be followed.
Bio-fertilizer:Biofertilizer is an environmentally friendly fertilizer that converts organic matter into nutrients available to algae mainly through the action of microorganisms. Commonly used biofertilizers are: EM bacteria pioneer, ultra-high concentration EM bacteria, which can effectively reduce ammonia nitrogen, hydrogen sulfide and other harmful substances in the water body and improve water quality. At the same time, EM bacteria can also inhibit the growth of harmful bacteria, promote the reproduction of beneficial microorganisms, and help to establish a stable pond ecosystem.
Second, master the correct fertilization method
When using fertilizer and water products, it is necessary to master the correct fertilization method. In general, choose sunny and windless weather when applying fertilizer, and avoid fertilizing in rainy or windy weather. At the same time, the amount of fertilizer should be determined according to the size of the pond and the breeding density to avoid the deterioration of water quality caused by excessive fertilization.
In addition, it is necessary to sprinkle evenly when fertilizing to avoid local excess or insufficiency. After fertilization, the aerator should be properly turned on to increase the dissolved oxygen content of the water body and improve the absorption rate of the fertilizer.
3. Use other water treatment agents in combination
At the same time as the use of fertilizer and water products, other water treatment agents, such as quicklime, copper sulfate, etc., can be used. Quicklime can adjust the pH value of water quality and increase the hardness of water bodiesCopper sulphate can prevent and control aquatic plant diseases and inhibit algae overgrowth. When using these water treatment agents, it is necessary to strictly follow the usage method and dosage on the instructions to avoid causing harm to lobsters.
4. Regularly monitor water quality
After using fertilizer and water products, the water quality should be monitored regularly, including pH value, dissolved oxygen, ammonia nitrogen, nitrite and other indicators. If a problem with water quality is found, measures should be taken to adjust it in time. At the same time, the amount and frequency of fertilization should be adjusted according to the monitoring results to ensure that the water quality of the pond is stable.
