Fertilizer and water management in ponds is essential for aquaculture production, and choosing the right fertilizer can not only promote the growth of aquatic organisms, but also maintain the stability of water quality. The following will be ideal for deep pond fertilizer water.
Microbial fertilizersAdvantages:
In recent years, the application of microbial fertilizers in pond fertilizer water has gradually attracted people's attention. Commonly used are EM Pioneers, which contain a large number of beneficial microorganisms that can break down organic matter in the pond and release nutrients for plants to absorb. At the same time, these microorganisms can also inhibit the growth of harmful microorganisms and reduce the occurrence of diseases. It is recommended to use microbial fertilizer with multi-effect fertilizer and water pioneer for better effect.
Advantages of organic fertilizers
For pond fertilizer water, organic fertilizer is a recommended choice. Chicken manure, cow manure, etc. are all common types. They are rich in nutrients such as nitrogen, phosphorus, and potassium, which are necessary for the growth of aquatic plants. Compared with chemical fertilizers, organic fertilizers release more slowly, which can reduce the loss of nutrients, so that nutrients can be absorbed by aquatic plants for a longer period of time.
Proper "fertilizer water" is an important part of pond farming, and here are a few key steps:
Determine the amount of fertilizer to be applied:The amount of fertilizer is determined based on factors such as the area, depth, substrate and water temperature of the pond. Generally speaking, the amount of fertilizer applied each time should be controlled at about 1-2 kg per mu.
Choose the right product:According to the breeding needs and pond conditions, choose the right fertilizer and water products. For example, if there are few aquatic plants in the pond, you can choose a fertilizer based on nitrogen and phosphorus;If there are many aquatic plants in the pond, you can choose fertilizers based on organic matter and microbial fertilizers.
Master the fertilization time:The fertilization time should be selected in the morning or evening on a sunny day, and fertilizer should be avoided at noon or in rainy weather. In addition, the amount and frequency of fertilization should be adjusted in time according to the changes in water quality during the breeding process.
Keep the water fresh:In the process of fertilizing water, the water quality should be kept fresh, and new water should be replaced in time or water purification agent should be used to maintain the stability of water quality.
Monitoring water quality:Water quality should be regularly monitored in the process of fertilizer and water, including ammonia nitrogen, phosphorus content, dissolved oxygen and other indicators. If abnormal water quality is found, measures should be taken to deal with it in time.
In short, choosing the right fertilizer and water products is the key link in pond fertilizer and water. When choosing fertilizer and water products, it is necessary to consider the specific situation of the pond and the breeding needs, choose natural, efficient and environmentally friendly fertilizer and water products, and control the amount and frequency at the same time to avoid adverse effects on aquatic organisms and water quality.
