Problems solved by technology

[0010] (2) The composition of organic agricultural miscellaneous fertilizers varies greatly, and the fertilizer effects are inconsistent. It is difficult to grasp the accurate dosage of various fertilizers when using them, that is, there are certain difficulties in quantitative use.
[0011] (3) Organic agricultural miscellaneous fertilizers (especially agricultural miscellaneous fertilizers that have not been fully matured) contain a large number of pathogenic bacteria, spoilage bacteria, pests and eggs. If they are directly applied to shrimp ponds, it will not only cause frequent breeding diseases and affect The survival of shrimp seedlings may cause the spread and prevalence of major diseases, which is extremely harmful
[0012] (4) The use of organic fertilizers is large and the operation is heavy
[0015] It can be seen that the control of water quality in artificial shrimp ponds has become a key issue restricting the development of shrimp farming industry, but there is still no practical and effective way in China

Embodiment 1

[0030] The first step is to add 50kg of phosphoric acid with a water content of 50% and 30kg of tap water to the high-temperature reactor, heat the acid solution to 85°C, and put in 10kg of low-temperature soybean meal (passed through a 100-mesh sieve) and 10kg of tea seed cake powder (passed through a 100-mesh sieve) , stirring while feeding; after the feeding is completed, the temperature starts to rise, and the temperature rises to 114°C within 1 hour, and the material is discharged after constant temperature for 12 hours to obtain liquid A;

[0031] The second step takes 25kg of fresh beer yeast mud (about 75% of water content), adds 25kg of tap water, 1kg of salt, passes through a 100-mesh non-woven fabric sieve after mixing; heats up to 55°C, and adds 0.1kg of papain (the activity is 600,000 u / gram), stir evenly, discharge after constant temperature for 15 hours, obtain B liquid;

[0032] The third step is to mix 100kg of liquid A and 50kg of liquid B, control the temper...

Embodiment 2

[0035] The first step is to add 50kg of phosphoric acid with a water content of 50% and 30kg of tap water to the high-temperature reactor, heat the acid solution to 82°C, and put in 10kg of low-temperature soybean meal (passed through a 100-mesh sieve) and 10kg of tea seed cake powder (passed through a 100-mesh sieve) , stirring while feeding; after the feeding is completed, the temperature starts to rise, and the temperature rises to 117°C within 1.5 hours, and the material is discharged after constant temperature for 8 hours to obtain liquid A;

[0036] The second step takes 25kg of fresh beer yeast mud (about 75% of water content), adds 30kg of tap water, 1kg of salt, passes through a 100-mesh non-woven fabric sieve after mixing; heats up to 55°C, and adds 0.2kg of papain (the activity is 500,000 u / gram), stir evenly, discharge after constant temperature 18 hours, obtain B liquid;

[0037] The third step is to mix 100kg of liquid A and 50kg of liquid B, control the temperat...

Embodiment 3

[0040] The first step is to add 100kg of phosphoric acid with a water content of 50% and 60kg of tap water to the high-temperature reactor, heat the acid solution to 100°C, and put in 20kg of low-temperature soybean meal (passed through a 200-mesh sieve) and 20kg of tea seed cake powder (passed through a 200-mesh sieve) , stirring while feeding; after the feeding is completed, the temperature starts to rise, and the temperature rises to 115°C within 1.5 hours, and the material is discharged after constant temperature for 11 hours to obtain liquid A;

[0041] The second step takes 50kg of fresh beer yeast mud (about 75% of water content), adds 75kg of tap water, 2kg of salt, passes through a 100-mesh non-woven fabric sieve after mixing; heats up to 53°C, and adds 0.3kg of papain (the activity is 500,000 u / gram), stir evenly, discharge after constant temperature 20 hours, obtain B liquid;

[0042] The third step is to mix 200kg of liquid A and 100kg of liquid B, control the temp...

Abstract

An ecological organic regulator for the water in pond used to artificially culture shrimp is prepared from low-temp bean cake and beer yeast mud through controllable hydrolysis by acidic enzyme method, and high temp polymerizing and chelating reactions. It contains N,P, free amino acids, soluble protein, polyose, minerals, vitamines, etc. It benefits the great reproduction of animal plankton for increasing the utilization rate of feed.

Description

(1) Technical field [0001] The invention relates to the technical field of aquaculture, in particular to an organic ecological regulator for artificial shrimp pond water and a preparation method thereof. (2) Background technology [0002] In the past 20 years, with the depletion of natural aquatic resources and the intensification of water pollution, the amount of aquatic animals captured from natural water bodies has become less and less, which is far from meeting people's growing demand for aquatic products. At the same time, the rapid development of the global aquaculture industry has become the most effective way to solve the above contradictions. The most important feature of this development is the transformation from traditional open farming methods to semi-intensive or even intensive, facility-based, and intensive farming methods. The application of high and new technologies such as bioengineering technology, water treatment technology, automatic monitoring and comp...
