Problems solved by technology

[0005] "Fish farming first raises water". Good water quality is the premise to ensure high yield and high-quality aquatic products. In my country's aquaculture, there has been a lot of randomness in "fertilizing fish" for decades, and many products lack water quality. The understanding of characteristics, without special formula, leads to poor effect, low utilization rate of nutrient elements, and causes water pollution and environmental damage

Embodiment 1

[0033] The superfine powder aquatic product biological fertilizer in the present embodiment, used raw material and content (%) thereof are as follows: ammonium chloride 35%, urea 15%, calcium superphosphate 10%, monoammonium phosphate 25%, other mixture 5% ( That is: according to the weight ratio, manganese sulfate, magnesium sulfate, zeolite powder = 1:2:2), humic acid 10%; the above-mentioned raw materials are mixed and subjected to ultrafine pulverization (according to conventional methods, for example, adopt ultra-fine powder produced by Jiangsu Muyang Group) Micro pulverizer (machine model: SWFL130E), after the control spindle speed is 1570rpm), the particle diameter of the finished biological fertilizer obtained is 200 meshes to≤120 mesh ratio is 38%, the particle diameter of biological fertilizer≤200 mesh ratio is 37%, The particle diameter of the biological fertilizer > 120 mesh ratio is 25%, that is, the base material of the superfine powder aquatic biological fertiliz...

Embodiment 2

[0054] The superfine powder aquatic biological fertilizer formula, nutrient content and processing technology thereof in this implementation example are the same as "Example 1.

[0055] The preparation method of the Bacillus subtilis bacterial agent is obtained with reference to the method described in Example 1.

[0056] The superfine powder aquatic product biological fertilizer of the present invention was used in a reservoir in Feidong County, Anhui Province (see Table 4) in 2014, with an area of ​​1000 mu (equivalent to an area of ​​666000m2) 2 ), mainly farming grass carp, silver carp, bighead carp and round bream. According to the amount of 1.2 kg of bio-fertilizer / mu·meter (the average water depth of each mu is 1 meter), use it twice a month (fertilize once every 7-10 days), and apply it on sunny days; the method of application is to pour this product into water. The effect of the invention is shown in Table 4

Abstract

The invention particularly relates to a superfine powder biological fertilizer for aquiculture. The superfine powder biological fertilizer is characterized in that the biological fertilizer comprises effective elements in percentage by pure nutrients as follows: larger than or equal to 18.5% of nitrogen, larger than or equal to 13.0% of phosphorus pentoxide and larger than or equal to 1.0% of potassium oxide, wherein the number of living bacteria in a bacillus subtilis microbial agent is at least 108 cfu / g; after raw materials are mixed and subjected to superfine grinding, the biological fertilizer with particle diameters smaller than or equal to 120 meshes or larger than 200 meshes accounts for 38%, the biological fertilizer with particle diameters smaller than or equal to 200 meshes accounts for 37%, and the biological fertilizer with particle diameters larger than 120 meshes accounts for 25%. As for an intensive culture pond and a large water surface, the proportion of nitrogen and phosphorus in water is adjusted, and an algal phase is adjusted, so that physicochemical and biological factors of the water are more suitable for growth of fishes. The color of water in a fertilization area is good, the nutrient utilization rate is high, the culture survival rate is remarkably increased, the incidence rate is reduced by about 50%-70%, the use quantity of culture medicines is reduced by 43%-45%, and the income from every 666 m<2> of the water surface is increased by 100-200 RMB yuan.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a superfine powder biological fertilizer for aquatic products. It is related to the technical field of special fertilizer for aquatic products. Background technique [0002] my country is a big country in aquaculture, and its aquaculture production has accounted for more than 70% of the world's aquaculture production for many years. In 2014, the output of aquaculture aquatic products in my country reached 47.62 million tons, accounting for 73.8% of the total output of 64.5 million tons. Aquatic products provide more than 30% of the protein for the people. While the aquaculture industry is developing rapidly, there are also problems such as few high-quality aquatic products, declining product quality, few export-earning brands, serious waste of resources, and serious environmental damage. Food safety, food safety and environmental safety have become the main focus...
