1. Choose the right fertilizer.
The key to fertilizer water is to choose the right fertilizer. In spring, due to the lower temperature, the decomposition rate of organic matter is slower, so it is necessary to choose fertilizers rich in organic matter and nutrients, which decompose and absorb quickly to promote the growth of plankton. We use: multi-effect fertilizer and water pioneer, rich in a variety of amino acids and trace elements, small molecules and easy to absorb, can be low temperature and rapid fertilizer water.
2. Microbial preparations.
In order to improve fertilizer efficiency, some microbial preparations can be selected and mixed with organic fertilizers to accelerate the decomposition of organic matter and the release of nutrients, improve the ecological environment of water bodies, and promote the improvement of fertilizer and water efficiency. Experienced breeding friends recommend using: EM bacteria pioneer, high content, strong activity, can promote fertilizer water, improve the environment of fish ponds.
3. Control the amount of fertilizer.
Excessive fertilization can lead to deterioration of water quality and toxic effects on fish. Too little fertilization and insufficient nutrients to meet the growth needs of plankton. Therefore, the amount of fertilization needs to be determined according to the specific situation of the pond. When fertilizing, the principle of small amount and multiple times should be followed, and the amount of fertilizer should be adjusted in time to maintain the stability of water quality.
Fourth, reasonable combination of other nutritional elements.
In addition to organic fertilizers, it is also necessary to reasonably match other nutrients, such as nitrogen and phosphorus. These nutrients are important elements to promote the growth of plankton, and some inorganic fertilizers can be added in moderation to supplement the required nutrients. However, it should be noted that the amount of inorganic fertilizer should be added moderately, and excessive use will have a negative impact on water quality.
