Embodiment 1

[0030] S1. Paddy field selection: select a 35-mu paddy field in the downstream of the mountain area near the stream, and introduce the stream water into the paddy field, which is convenient for water supply and drainage, and the water quality is good;

[0031] S2. Paddy field improvement: Dig the inside of the paddy field ridge into a ring-shaped ditch with a width of 5 meters and a depth of 1 meter, and build ditches connecting multiple paddy fields on the outside of the paddy field; then build inlet and outlet outlets according to the pattern of high irrigation and low drainage The water flow is automatically injected into and out of the paddy field by the drop to keep water flowing in and out of the ditch; at the same time, blockages and gates are set up at the inlet and outlet to prevent the entry of harmful organisms and the escape of crayfish; High smooth anti-escape net to prevent crayfish predators such as rats, snakes and frogs from entering the rice fields;

Embodiment 2

[0037] S1. Paddy field selection: Select a paddy field with an area of ​​20 mu in the downstream of the mountain area near the stream, and introduce the stream water into the paddy field, which is convenient for water supply and drainage, and the water quality is good;

[0038] S2. Rice field improvement: Dig the inside of the paddy field ridge into a circular shrimp ditch with a width of 4 meters and a depth of 0.8 meters, and build ditches connecting multiple paddy fields on the outside of the paddy field; then build inlet and outlet outlets according to the pattern of high irrigation and low drainage. The water flow is automatically injected into and out of the paddy field by the drop to keep water flowing in and out of the ditch; at the same time, blockages and gates are set up at the inlet and outlet to prevent the entry of harmful organisms and the escape of crayfish; High smooth anti-escape net to prevent crayfish predators such as rats, snakes and frogs from entering th...

Embodiment 3

[0044] S1. Paddy field selection: select a 35-mu paddy field in the downstream of the mountain area near the stream, and introduce the stream water into the paddy field, which is convenient for water supply and drainage, and the water quality is good;

[0045] S2. Paddy field improvement: Dig the inside of the paddy field ridge into a ring-shaped ditch with a width of 6 meters and a depth of 1.2 meters, and build ditches connecting multiple paddy fields on the outside of the paddy field; then build inlet and outlet outlets according to the pattern of high irrigation and low drainage The water flow is automatically injected into and out of the paddy field by the drop, so that there is continuous water in and out of the ditch; at the same time, blockages and gates are set up at the inlet and outlet to prevent the entry of harmful organisms and the escape of crayfish; High smooth anti-escape net to prevent crayfish predators such as rats, snakes and frogs from entering the rice fi...

Abstract

A method for breeding lobsterlings in a mountainous area rice field comprises the following steps that S1, a rice field is selected; S2, the rice field is improved; S3, grass is planted with a fertilizer and water, wherein channels are disinfected before water injection and are injected with water after one week; S4, shrimp larvae are put; S5, breeding and management are performed; S6, fishing is performed. The method has the advantages that specific high-quality water resources in a mountainous area and mountain spring water micro-flow hot in winter and cold in summer are utilized to breed the lobsterlings in the rice field, a lobsterling growth environment is reasonably controlled, breeding water quality management is simple, and the lobsterling growth speed is improved, so that bred lobsterlings are bright in color and luster, delicious and high in nutrition value, meanwhile the quality and conditions of the lobsterlings are ensured, and the lobsterlings have a high market value. Lobsterling breeding and rice planting are organically combined, so that lobsterlings and rice produce mutualistic symbiosis, the productivity of farmland is fully played, the additional value of farmland management is improved, and the method has good economic, beneficial and ecological benefits.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a method for cultivating crayfish in rice fields in mountainous areas. Background technique [0002] Crayfish, scientifically known as Procambarus clarkii (Procambarus clarkii), has fast reproduction, short breeding cycle, delicious meat, rich nutrition, great market demand, and broad development prospects. [0003] In recent years, due to the sharp increase in market demand, the sharp decrease in natural resources of crayfish, and the gradual increase in market prices, artificial large-scale high-density breeding has been carried out in most provinces and cities to meet market demand. However, while large-scale farming brought high yields, it also caused frequent outbreaks of crayfish diseases, and caused water quality deterioration, drug abuse, and quality degradation, which seriously affected the economic benefits of crayfish farming. Therefore, how to solve the ...
