Problems solved by technology

At present, the coverage of aquatic plants in the main shrimp ponds is less than 30%, and even many shrimp ponds do not grow aquatic plants. Although the pond water is easy to fertilize, there will be algae blooms at high temperatures, and the water quality is difficult to control, affecting the yield and quality of freshwater shrimp. The quantity and management of aquatic plants in freshwater shrimp ponds are the technical "bottlenecks" of freshwater shrimp ponds

Embodiment 1

[0021] A method for planting composite aquatic plants in freshwater shrimp ponds, comprising the steps of:

[0022] (a) Disinfection of the clear pond: after the spring shrimps are caught at the end of June, drain the pond water, remove excess silt, reinforce the ridge, and expose the pond to the sun for 9 days; use 125 kg / mu of quicklime or 9 kg / mu of bleaching powder to splash the whole pond disinfect;

[0023] (b) planting aquatic plants: in July, after the pond is cleared and disinfected, select a non-polluted water source, filter it with a 60-mesh gauze, and then enter the pond at a height of 30 centimeters; Ribbon-like throwing seed-wrapped hydrilla bundles, the strip width of the hydrilla bundles is 3.0 meters, the interval between the strips is 6.0 meters, and the distance between the bundles is 1.5× 1.5 meters, every bundle of Hydrilla verticillium bundle is made up of 5-10 Hydril algae branch sections, and the long 20-30 centimetre of described Hydrilla verticillium...

Abstract

The invention discloses a method for planting composite aquatic plants in a freshwater shrimp pond. The method comprises the steps of pond cleaning and disinfection, aquatic plant planting, topdressing and water regulation, aquatic plant management and protection and the like. Low-temperature-resistant and high-temperature-resistant aquatic plants are planted in the freshwater shrimp main culturepond in a matched mode, the amount of the aquatic plants is controlled to account for 55%-65% of the area of the pond through stubble cutting, water fertilizing and other measures, the growth activityspace of freshwater shrimps is enlarged to the maximum extent, pond ecology is created, and the yield, quality and benefits of freshwater shrimp culture are improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for planting compound aquatic plants in freshwater shrimp ponds. Background technique [0002] Freshwater shrimp, scientific name Macrobrachium japonica, belongs to the phylum Arthropoda, Crustacea, Decapoda, Longarm Shrimpidae, and Macrobrachium genus. It is a freshwater cultured shrimp with delicious meat, rich nutrition, short breeding cycle and high economic value. kind. Freshwater shrimp like to inhabit freshwater lakes, ponds, and areas with lush aquatic plants along the banks of rivers, but their swimming ability is weak, and they often climb and crawl among aquatic plants. [0003] In the main breeding mode of freshwater shrimp in ponds, planting aquatic plants can effectively increase the activity space of freshwater shrimps, increase the carrying capacity of freshwater shrimps in ponds, and increase aquaculture production. In addition, aquatic plants can c...
