Water-fertilizing agent for shrimp ponds

Abstract

The invention provides a water-fertilizing agent for shrimp ponds, which mainly comprises the following components in percentage by weight: 55-95% of sodium nitrate, 1-40% of zeolite powder and 0.5-7% of potassium chloride. Compared with common water-fertilizing products for ponds, the water-fertilizing agent for shrimp ponds disclosed by the invention has the advantages that: through combining with fertilizers for enhancing the growth of beneficial microalgae, selecting a nitrogen compound (sodium nitrate) which is high in algae bioavailability and has oxidation property, and supplementing a moderate amount of silicate (zeolite powder) and potassium salt (KCl), the problems of generating ammonia by using other water-fertilizing products and consuming oxygen in the process of ammonia generation are solved, the oxygen supply of a pond can be ensured, and an appropriate biological control can be performed; and the water-fertilizing agent for shrimp ponds is easy to operate, causes no harm to the environment, and accords with the requirements of sustainability.

Description

technical field [0001] The invention relates to a pond fertilizer and aquatic product, in particular to a fertilizer and water agent for shrimp ponds. Background technique [0002] Shrimp is a pillar species of my country's aquaculture industry. It has developed rapidly in recent years. By 2010, the aquaculture area will exceed 5 million mu and the output will exceed 1 million tons. Fertilizer water refers to the cultivation of plankton in shrimp ponds as basic biological bait, especially single-celled algae such as diatoms and green algae. Fertilizer and water are important management measures in the process of shrimp farming. The more complex the algal phase is, the more stable the water color will be. In layman's terms, "shrimp farming first raises water", the success of shrimp farming is inseparable from the quality of fertilizer and water work before seedlings are released. [0003] At present, the fertilizers used in the early stages of shrimp ponds are mainly urea o...

Problems solved by technology

For example, ammonia will be released when urea is hydrolyzed, which has certain toxicity to aquatic animals; and ammonium nitrogen needs to be oxidized into nitrate before being used by microalgae, which needs to consume a lot of oxygen. In addition, 1g of ammonia will also consume 7g of nitrate in the pond. Calcium carbonate, resulting in the lack of alkali content in the water body, resulting in a decrease in the pH value of the water body, which is also detrimental to the success of shrimp farming
