Ponds are a habitat for many aquatic creatures. Proper fertilizer and water not only provide essential nutrients for aquatic organisms, but also promote the balance of aquatic ecosystems. This article will introduce several commonly used methods of pond fertilization and watering, and ** their respective advantages and disadvantages.
1. Biological fertilizer
Biofertilizer is a relatively environmentally friendly method of pond fertilizer and water, which includes microbial agents, bio-organic fertilizers, etc. More commonly used collocation: EM bacteria pioneer + multi-effect fertilizer and water pioneer. Ultra-high concentration of EM cultures can help break down organic matter and nutrients in the pond, thereby reducing the risk of deterioration of the pond's water quality. The multi-effect fertilizer and water pioneer: rich in a variety of amino acids, trace elements and other nutrients, small molecules and easy to absorb, can quickly replenish a variety of nutrients needed by aquatic organisms.
2. Organic fertilizer
Organic fertilizer is a commonly used pond fertilizer and water method, which includes livestock and poultry manure, crop straw, domestic sewage, etc. After fermentation, these organic substances can release a large amount of nutrients such as nitrogen and phosphorus into the pond, thereby promoting the growth of aquatic organisms. However, excessive use of organic fertilizers can lead to deterioration of pond water quality, such as the appearance of harmful substances such as ammonia nitrogen and nitriteSecondly, organic fertilizer contains a large number of germs and parasites, which pose a threat to aquatic life.
3. Chemical fertilizers
Chemical fertilizer is a relatively simple method of pond fertilizer and water, which includes urea, diammonium hydrogen phosphate, etc. Fertilizers can quickly release nutrients into ponds, which can promote the growth of aquatic life. However, the excessive use of chemical fertilizers will lead to the deterioration of pond water quality, such as the appearance of harmful substances such as ammonia nitrogen and nitrite, which will affect its growth. Therefore, inorganic fertilizers are generally only used in emergency fertilizer and water situations.
Fourth, mixed fertilizer
Mixed fertilizer is a more flexible pond fertilizer and water method, which can mix organic fertilizer, chemical fertilizer and biological fertilizer in a certain proportion. In this way, the advantages of various fertilizers can be combined to achieve the best fertilizer and water effect. However, there are also some problems with the use of mixed fertilizers. First of all, the mixing ratio needs to be rigorously tested and verified;Secondly, the use of mixed fertilizers requires more time and effort.
To sum up, the selection of appropriate pond fertilizer and water methods needs to be comprehensively considered according to the actual situation. In the process of breeding, the most suitable fertilizer and water method should be selected according to the growth needs of aquatic organisms, pond water quality conditions, weather and other factors. At the same time, it is also necessary to pay attention to controlling the amount and frequency of fertilization to avoid negative effects on aquatic organisms and the pond environment.
