A fully soluble aquatic fertilizer and its preparation method

Abstract

The present invention discloses a fully soluble aquatic fertilizer and its preparation method and pertains to aquaculture field. The aquatic fertilizer of the present invention comprises monoammonium phosphate 15-45%, sodium humate 12-20%, sodium silicate 5-12%, compound premix 8-13%, and urea 30-40%. The compound premix is mainly composed of trace elements. Firstly, the aquatic fertilizer of the present invention has comprehensive nutrition and balanced formula; secondly, the present invention has high dissolution speed and utilization rate; thirdly, the present invention features simple use method, small use amount, sufficient content, long lasting time and low cost; fourthly, the present invention can not only promote the mass propagation of food organisms of aquatic animals but also specifically cultivate helpful algae, improve water quality, increase dissolved oxygen, effectively avoid pond poisoning, reduce diseases, lower feed coefficient and enhance fish immunity; the present invention is green and environment-friendly, and has stable quality and no harm on human and animal and no pollution on environment.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to a fully soluble aquatic fertilizer and a preparation method thereof. Background technique [0002] For a long time, in aquaculture, organic fertilizers and chemical fertilizers are generally used to supplement nutrients for ponds and cultivate plankton to provide natural bait for aquatic animals. This method can significantly improve the productivity of ponds and achieve the effect of increasing production and income. But at the same time, there are many problems. Traditional organic fertilizers carry a large number of harmful bacteria, and after use, the organic matter will be fermented in water and consume a lot of oxygen, resulting in disease outbreaks or hypoxia floating heads in cultured species. Therefore, Xiaoyi should directly use them in ponds It is time-consuming and labor-intensive to apply and use after fermentation; chemical fertilizers such as ammonium bicarbo...

AI Technical Summary

Problems solved by technology

However, nitrogen (in N) and phosphorus (in P) in this fertilizer 2 o 5 The sum of the content is 15-20%, the fertility is low, and the phosphate rock powder is used as the main raw material, the production cycle is long (need to ferment for more than 14 days), the solubility of phosphorus is low, the fertilization is relatively large, and the content of chelating agent is small and other disadvantages, and only suitable for freshwater fish ponds

[0004] In short, most of the current aquatic fertilizers mostly add a single substance. For example, only some biological agents or phosphate double salts, thiophosphates, amino acids, etc. are added to the processed conventional fertilizers. It is difficult to change the breeding status as a whole. Full dissolution and incomplete nutrients lead to incomplete fertilizer effects

Some fertilizers with live bacteria can also cause a large number of rotifers in the water to multiply during use, resulting in hypoxia and floating heads of aquatic animals.
