A method for using pond bottom mud fertilizer and water in the early stage of aquaculture

Abstract

The invention provides a method for using the pond bottom mud water at an early stage of aquaculture. The method is characterized by mainly comprising a pond (1), a foam box (2), a wooden row (3), a wooden pile (4), a rope (5), a woven bag (6), an angle iron (7), a first steel bar ring (8), a steel bar (9), a second steel bar ring (10), a processing barrel (11), a handle (12), a steel grille (13),an open bottom (14), a handle (15), a collecting bucket (16), a sealed bottom ( 17), a handle bar (18) and an elliptical head (19). The method is advantaged in that the organic matter and the inorganic matter contained in the pond bottom mud are transformed into a nutrient salt which can be absorbed by the phytoplankton in the pool water through drying, powder mashing, oxidizing and decomposing so as to cultivate bait organisms in the pool water, no chemical fertilizers and no organic fertilizers are utilized, low carbon and environmental protection are realized, and healthy and efficient pond farming is realized.

Description

technical field [0001] The invention relates to the technical field of pond culture, in particular to a method for using pond bottom mud fertilizer and water in the early stage of aquaculture. Background technique [0002] In the pre-culture pond fertilizer water, the inorganic fertilizer is usually dissolved in the water and poured into the pond, or the fermented organic fertilizer is put into the pond to cultivate the plankton in the pond, provide biological bait for the fish fry and shrimp fry, and improve The survival rate of cultured seed is improved, and the output and benefit of breeding production are increased. Using inorganic fertilizers and water, the speed of fertilizer and water is fast, and a large number of phytoplankton can be cultivated in a short period of time. It needs to consume a lot of nutrients to ensure growth and reproduction. After the fertilizers put into the pond are absorbed and utilized, if there is no Re-investment, a large number of phytopla...

AI Technical Summary

Problems solved by technology

Using inorganic fertilizers and water, the speed of fertilizer and water is fast, and a large number of phytoplankton can be cultivated in a short period of time. It needs to consume a lot of nutrients to ensure growth and reproduction. After the fertilizers put into the pond are absorbed and utilized, if there is no Re-investment, a large number of phytoplankton died due to lack of nutrient absorption, sank to the bottom of the pond, and the zooplankton that depended on it could not reproduce, resulting in a decrease in the number of plankton in the pond and a decrease in the survival rate of seedlings

Use organic fertilizer and water, the speed of fertilizer and water is slow, it is difficult to control, if the dosage is small, the plankton cultivation process in the pond is slow, the water color is not easy to change, the seedlings cannot prey on the bait organisms in time, if the dosage is too large, the plankton in the pond will multiply excessively , Excessive fertilizer and water, the pond water environment will easily deteriorate, which will easily lead to the occurrence of diseases and affect the growth and survival rate of seedlings
