Embodiment 1

[0032] Embodiment 1: a kind of cleaning method of aquatic plants disclosed by the present invention comprises the following steps:

[0033] (1) Enclosing the pond: Construct around the inner wall of the pond, build a concrete wall, enclose the entire pond, and set up a gate for discharging or entering water in the pond. 1 meter.

[0034] (2) Soil modification at the bottom of the pond before weeding: Soak with enzyme for two hours, add water, and sprinkle it into the pond. The amount of enzyme used per mu of water is 0.5kg. The enzyme neutralizes and decomposes the acidic organic matter in the bottom soil of the pond. Neutralize the PH value of the pond bottom soil; after completion, fill the pond with humus sand and let it settle for 5 days, so that the humus sand forms a layer of humus sand on the surface of the pond bottom soil.

[0035] (3) Clearing the grass: quickly clean the moss: fencaojing: the yellow sand is neutralized and stirred at a ratio of 1:2:50 to obtain the...

Embodiment 2

[0040] Embodiment 2: a kind of cleaning method of aquatic plants, wherein, the soil modification method at the bottom of the pool after cleaning grass is as follows:

[0041] The quicklime is processed into quicklime balls and evenly sprinkled in the pond. The dry sprinkle amount per mu of water is within the range of 30-40 catties. The quicklime reacts with water to generate oxygen and increase the oxygen content in the water.

Abstract

The invention relates to an aquatic plant cleaning method. The method comprises the following steps: (1) pond enclosing: constructing a concrete enclosure around the inner wall of a pond so as to enclose the whole pond, arranging a gate for discharging water or feeding water into the pond, and opening the gate to discharge water after the pond is constructed so as to allow the water surface of thepond to be reduced by 1 m or less; (2) grass clearing: neutralizing and stirring a moss quick-cleaning agent, prometryn and yellow sand according to a ratio of 1: 2: 50, uniformly spreading 53 kg ofthe formed mixture on each mu of water surface with a depth of no more than 1 m, and maintaining the mixture on the surface for 6-7 days; (3) fishing out killed and floating-up spirogyra, cladophora,green tubular grass and moss; and (4) feeding of a breeding variety: injecting water into the pond on sunny days, and putting the breeding variety into the pond for breeding after water injection is completed. The method has the advantages of good waterweed removing effect, low cost, short period and suitability for feeding of various culture varieties into ponds.

Description

technical field [0001] The invention relates to the technical field of aquatic weed removal, in particular to a method for cleaning aquatic weeds. Background technique [0002] Sometimes when the water quality is well maintained, water plants will grow wildly in the lake, which will greatly affect the lake view, and even cause the water inlet and outlet, and the vent gate to be blocked. Therefore, it is often necessary to treat the aquatic plants in the lake. The common methods of aquatic plant treatment include manual salvage and cleaning, mechanical mowing, quicklime cleaning, fish ecological method, and spraying chemicals. [0003] In the prior art, in a Chinese patent document with the publication number CN105875444A, a method for regulating aquatic plants in crab ponds is disclosed. Planting aquatic plants: a deep ditch is provided in the pond; a seine net is arranged around the deep ditch, and Plant Elodea in the deep ditch; plant Hydrilla verticillium seedlings outsi...
