Cake-shaped ecologic fish guano

Abstract

The invention discloses cake-shaped ecologic fish guano which is characterized by comprising 60% of half-dry cow dung, 15% of straw powder, 10% of humus, 12% of fowl manure and 3% of night soil. The cake-shaped ecologic fish guano is prepared by sufficiently mixing the raw materials, wherein the water content is 60%; uniformly mixing and stacking the raw materials; spraying 2% of EM (Effective Microorganism) bacterium; adding a water solution containing 3kg of urea and monopotassium phosphate respectively; pressing the materials into the cake-shaped ecologic fish guano by using a mold; and drying the cake-shaped ecologic fish guano. Each piece of the cake-shaped ecologic fish guano is 5kg in weight; when the cake-shaped ecologic fish guano is used, a polyethylene rope threads through the middle of the cake-shaped ecologic fish guano so as to tie and suspend the cake in water. One piece of the cake-shaped ecologic fish guano is used in each 100 m<2> pool, and the cake-shaped ecologic fish guano is suspended in the water by using a stick or a buoy; the nutrient elements are constantly and slowly released, so that the plankton in the water can obtain sufficient nutritional ingredients, thereby prompting the growth of hypophthalmichthys nobilis; and the cake-shaped ecologic fish guano has easily-accessible raw materials, is convenient to implement and remarkable in effect, and has popularization values.

Description

technical field [0001] The invention relates to the technical field of aquatic products, in particular to a circular cake-shaped ecological fish fertilizer. Background technique [0002] Silver carp and bighead carp feed on plankton. Silver carp mainly feed on phytoplankton in the water body, and bighead carp mainly feed on zooplankton in the water body. Under artificial breeding conditions, due to the high density of silver carp and bighead carp, the plankton in the water body Biology is far from meeting the requirements of silver carp and bighead carp. Artificial application of large amounts of organic fertilizers will cause pollution and have an impact on the water quality environment. Application of inorganic fertilizers, due to the single nutrient composition and quick release of fertilizer effect, will cause excessive nutrient composition in some waters in a short period of time, forming Fertilizer pollution makes it difficult to balance the reproduction of plankton.

[0002] Silver carp and bighead carp feed on plankton. Silver carp mainly feed on phytoplankton in the water body, and bighead carp mainly feed on zooplankton in the water body. Under artificial breeding conditions, due to the high density of silver carp and bighead carp, the plankton in the water body Biology is far from meeting the requirements of silver carp and bighead carp. Artificial application of large amounts of organic fertilizers will cause pollution and have an impact on the water quality environment. Application of inorganic fertilizers, due to the single nutrient composition and quick release of fertilizer effect, will cause excessive nutrient composition in some waters in a short period of time, forming Fertilizer pollution makes it difficult to balance the reproduction of plankton. Although there are many types of biological fish fertilizers in use at present, the biological fish fertilizers used are not targeted, the composition is not clear, the form is not suitable, and the method of use is inappropriate. The effect of reproductive growth is limited, and the supply of biological feed for reproductive growth is insufficient, which affects the normal growth of silver carp and bighead carp
