specific Embodiment approach 1

[0013] Specific embodiment one: a kind of method for improving saline-alkali pond aquaculture output in this embodiment is carried out according to the following steps:

[0014] 1. The setting and layout of saline-alkali land: Divide the saline-alkali land into several pieces on average by digging ditches and building dams. Each piece of saline-alkali land is surrounded by dams 1, and the outside of dam 1 is ditches 2. Inside the ditches 2 along the length of the entire saline-alkali land And the length direction of each piece of saline-alkali land is buried with the alkali-discharge hidden pipe 3, and the alkali-discharge hidden pipe 3 buried in the ditch 2 along the length direction of the entire saline-alkali land is communicated with the alkali-discharge hidden pipe 3 buried in the length direction of each piece of saline-alkali land, along the entire saline-alkali land The alkali discharge hidden pipe 3 buried in the ditch 2 in the length direction communicates with one en...

specific Embodiment approach 2

[0018] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the saline-alkali land described in step 1 is a carbonate-type saline-alkali land.

[0019] Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0020] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the area of ​​each piece of saline-alkali land in step 1 is 1-10 mu.

[0021] Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for improving culture yield of a saline-alkali pond and relates to the technical field of pond culture. The purpose of the invention is to solve the problem of low culture yield of the existing saline-alkali water pond. The method comprises the following steps: by adopting a method of combining microorganism in-situ water quality regulation and control and pond-rice field ectopic circulating water quality regulation and control, concealed pipes are arranged in a rice field, leaked saline-alkaline water is collected after the saline-alkaline rice field is soaked, and pond ecological breeding is carried out, a microorganism water quality regulation and control technology, a scientific oxygenation technology, a scientific feeding technology and a pond bottom mud repairing and utilizing technology are integrated in the pond culture process, the pond microorganism water quality regulation and control technology is used for improving the pond water quality environment, and the content of ammonia nitrogen and nitrite nitrogen in a water body is reduced. The eutrophic water body is periodically circulated to the saline-alkali rice field, nutrient substances such as suspended solids, nitrogen and phosphorus in the water body are further removed, and the culture water body is circulated to the culture pond again through the alkali removal concealed pipe. The method for improving the culture yield of the saline-alkali pond can be obtained.

Description

technical field [0001] The invention relates to the technical field of pond cultivation, in particular to a method for increasing the production of saline-alkali pond cultivation. Background technique [0002] There are approximately 690 million mu of saline-alkali water resources in my country. Effective development and utilization of saline-alkali water resources through fisheries is of great significance for expanding aquaculture space, ensuring the supply of aquatic products, and realizing ecological restoration of saline-alkaline environments. However, in the process of aquaculture in saline-alkaline water ponds, due to the high salinity and pH of the water body, the ammoniacal nitrogen in the water body is highly toxic to the cultured animals, and the combination of high alkalinity and high pH and poor water quality environment is very difficult. Restricted the aquaculture output of saline-alkali pond to a large extent, so the output of saline-alkali pond aquaculture i...
