Abstract
The invention relates to a cleaning method of aquatic weeds in a river crab aquaculture pond. The cleaning method is characterized by comprising the following technique steps according to parts by weight: (1) dissolving 0.1-0.2 parts of sodium lauryl sulfate in 99.8-99.9 parts of water to obtain a sodium lauryl sulfate solution for future use; (2) dissolving 1.8-1.9 parts of polymeric ferric sulfate in 98.1-98.2 parts of water to obtain a polymeric ferric sulfate solution for future use; and (3) selecting a clear weather, uniformly splashing the sodium lauryl sulfate solution into the river crab aquaculture pond, and then, uniformly splashing the polymeric ferric sulfate solution, wherein the dosage of the sodium lauryl sulfate solution is 40-50kg in each mu of river crab aquaculture pond, and the dosage of the polymeric ferric sulfate solution is 40-50kg in each mu of river crab aquaculture pond. The cleaning method provided by the invention accelerates the stripping of the attachments, and meanwhile improves the transparency of the water body and deposits the suspended solids in the water to the bottom part of the pond to prevent the suspended solids from continuously depositing on the leaves of the aquatic weeds.
Description
Technical field
The present invention relates to the cleaning method of a kind of pasture and water, the cleaning method of pasture and water belongs to technical field of aquaculture in especially a kind of river crab cultivation pond.
Background technology
Along with applying of ecologically breeding river crabs technology, the raiser recognizes the importance of pasture and water in the foster crab of ecology day by day, as the saying goes: " the crab size is seen pasture and water ", visible pasture and water are determining ecological success or failure of supporting crab.At first, pasture and water carry out photosynthesis as waterplant and have increased dissolved oxygen in water, and propagating artificially for river crab pond high-density provides assurance; Secondly, self metabolizable energy of pasture and water promotes the absorption of the nutrient fertilizer in the water and soil earth, can also adsorb a part of objectionable impurities simultaneously, thereby purify water; In addition, pasture and water can stop and absorb a part of illumination, reduce water temperature, for river crab is built a suitable living environment; And pasture and water still are the natural good to eat bait of river crab, are the important sources of VITAMIN in the river crab food composition, are assurances balanced in nutrition.
The pond is because situation difference separately, and the situation of pasture and water growth also is not quite similar.Culturing the middle and later periods, increase along with charging capacity, the rising of temperature, transparency reduces gradually in the water body, suspension organic matter in the water body and dead algae etc. can be deposited on the surface of pasture and water, suppress the photosynthesis of pasture and water, and then cause the pasture and water vigor to reduce, progressively dead, thus the growth and breeding of river crab influenced.
Mainly be to add flocculation agent in water body in the prior art, purifying water body prevents that the suspension organic matter in the water body from continuing to deposit on the blade face, but does not have obvious removal effect for the settling that is attached to the pasture and water blade face.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the cleaning method of pasture and water in a kind of river crab cultivation pond is provided, accelerate peeling off of dirt settling, improve the transparency of water body.
According to technical scheme provided by the invention, the cleaning method of pasture and water in a kind of river crab cultivation pond, feature is to comprise following processing step: its formula rate by weight:
(1) 0.1～0.2 part of Sodium Lauryl Sulphate BP/USP is dissolved in 99.8～99.9 parts of water, obtains sodium lauryl sulfate solution, standby;
(2) 1.8～1.9 parts of bodied ferric sulfates are dissolved in 98.1～98.2 parts of water, obtain polymeric ferrous sulphate solution, standby;
(3) select bright day gas, the sodium lauryl sulfate solution of evenly splashing in the river crab cultivation pond earlier evenly splashes into polymeric ferrous sulphate solution again; The consumption of described sodium lauryl sulfate solution is every mu of river crab cultivation pond 40～50kg that splashes, and the consumption of polymeric ferrous sulphate solution is pond, the every mu of culture of Chinese mitten crab pond 40～50kg that splashes.
The mass concentration of described sodium lauryl sulfate solution is 0.1%～0.2%.
The mass concentration of described polymeric ferrous sulphate solution is 1.8%～1.9%.
The cleaning method of pasture and water in the river crab cultivation pond of the present invention by the surface tension between Sodium Lauryl Sulphate BP/USP reduction pasture and water blade face and the dirt settling, carries out oxidation by bodied ferric sulfate earlier again, accelerates peeling off of dirt settling; The powerful flocculating properties of bodied ferric sulfate can improve the transparency of water body simultaneously, makes the suspended substance sedimentation in the water arrive pond bottom, prevents that it from continuing to deposit on the pasture and water blade face.
Embodiment
The invention will be further described below in conjunction with specific embodiment.
Bodied ferric sulfate of the present invention is faint yellow unformed powdery solid, very easily water-soluble, it is a kind of novel inorganic polymeric flocculant that occurs the eighties in 20th century, it is fast to have hydrolysis rate, flocs unit density is big, the wide characteristics such as (4～10) of applicable pH range, have very strong in and the ability of electric charge on the suspended particle, very big specific surface area and very strong adsorptive power are arranged, can remove suspended substance in the water well, organism, sulfide, impurity such as heavy metal ion, has decolouring, deodorizing, function such as deemulsification and sludge dewatering, thereby be widely used in the mine, printing and dyeing, Industrial Wastewater Treatment such as papermaking.The present invention mainly utilizes the characteristics of bodied ferric sulfate flocculence and oxidisability, in purifying water body, and the dirt settling on the oxidizing water blade of grass face.
