Embodiment 1

[0015] In the embodiment of the present invention, alpha-naphthalene acetic acid is taken as: 5%, potassium sulfate: 20%, EDTA chelated iron: 0.5%, EDTA chelated copper: 0.5%, pure water 74%. Weigh the above components according to the total amount of 1000g, then heat the pure water to 60°C, dissolve α-naphthaleneacetic acid, and after the solution is cooled to room temperature, add the remaining potassium sulfate, EDTA chelated iron and EDTA chelated copper The materials are then dissolved one by one, stirred evenly and then filled. Finally packed into storage.

[0016] The action principle of each component among the present invention is as follows:

[0017] 1. α-Naphthylacetic acid: Molecular formula is C 12 h 10 o 2 , the molecular weight is 186.2, the pure product is a colorless crystal, the melting point is 130°C, it is easily soluble in acetone, ether, chloroform and other organic solvents, almost insoluble in cold water, and easily soluble in hot water. Stored at ...

Embodiment 2

[0024] A kind of aquatic plant growth promoter in aquaculture pond of the present invention, its component distribution ratio (by weight percentage):

[0025] In the embodiment of the present invention, take α-naphthyl acetic acid: 5%, potassium sulfate: 15%, EDTA chelated iron: 0.5%, EDTA chelated copper: 0.5%, pure water 79%. The above components were weighed according to the proportion of the total amount of 1000g, and then the pure water was heated to 62°C, and α-naphthaleneacetic acid was dissolved. After the solution is cooled to room temperature, dissolve the remaining materials one by one, stir evenly and fill. Finally packed into storage.

Embodiment 3

[0027] A kind of aquaculture pond waterweed growth promoter of the present invention, its component distribution ratio (by weight percentage): in the embodiment of the present invention, α-naphthalene acetic acid is: 4.8%, potassium sulfate is: 18%, EDTA chelated iron is: : 0.6%, EDTA chelated copper: 0.6%, pure water 76%. The above components were weighed according to the proportion of the total amount of 1000g, and then the pure water was heated to 60°C, and α-naphthaleneacetic acid was dissolved. After the solution is cooled to room temperature, dissolve the remaining materials one by one, stir evenly and fill. Finally packed into storage.

[0028] Use effect of the present invention is as follows:

[0029] It is used in a river crab breeding pond in Yixing, Jiangsu Province, with an area of ​​5 mu, and Elodea is planted in the pond. The biomass of Elodea was 420g / m in early April 2 , plant height 33cm. At that time, the water color of the pond was not good, the ammoni...

Abstract

The invention relates to an aquaculture pond float grass growth-promoting agent, belonging to the aquaculture technical field. The compositions in percentage by weight of the growth-promoting agent are: 4 to 6 percent of alpha-naphthylacetic acid, 15 to 20 percent of potassium sulphate, 0.4 to 0.6 percent of EDTA iron chelate, 0.4 to 0.6 percent of EDTA copper chelate and 74 to 80 percent of pure water, wherein pure water is heated up and then alpha-naphthylacetic acid is added in and dissolved in the pure water; when the solution is cooled down, potassium sulphate, EDTA iron chelate and EDTA copper chelate are added in and stirred evenly so as to obtain a finished product. The aquaculture pond float grass growth-promoting agent is free from the influence of environmental conditions and has convenient use and low application amount which is only 1 KG for every mu of water surface and every meter in depth; when used, the growth-promoting agent has quick returns and stable effects, and can quickly promote the growth of the float grass in a pond so as to reduce the content of nitrogen and phosphorous in water and to improve the environmental quality of the pond and the survival conditions of aquaculture organisms; therefore, the growth-promoting agent can effectively prevent aquaculture organism diseases and paroxysmal death, and increases the output and the quality of aquaculture organisms.

Description

technical field [0001] The invention relates to a growth promoter for aquatic plants in aquaculture ponds, belonging to the technical field of aquaculture. Background technique [0002] Because of its simple structure and strong controllability, the pond ecosystem has become the main water body of aquaculture production, and occupies a pivotal position in the fishery economy of our country. In my country's pond culture, especially the culture of shrimp and crabs, the growth of aquatic plants is of great significance for maintaining the stability of the pond ecosystem and improving the production and efficiency of culture. First of all, aquatic plants can provide abundant natural bait for aquaculture organisms. On the one hand, aquatic plants themselves are good plant-based bait for aquaculture organisms, such as: bitter grass, squid, hydrilla, duckweed, water peanuts, etc.; on the other hand, where aquatic plants are abundant, various plankton, aquatic insects, small fish ...
