Embodiment 1

[0025] A kind of method that the present invention proposes red crayfish paddy field culture, comprises the following steps:

[0026] a) Field engineering transformation of paddy field: After selecting the paddy field, use the winter slack season to trim the surface of the paddy field and excavate the shrimp ditch. The shrimp ditch is L-shaped, 2.0m wide and 1.0m deep, accounting for 8% of the total area of ​​the paddy field; Field ridges are trapezoidal in cross section, with a bottom width of 0.8m, a top width of 0.4m, and a top height of 0.8m above the field level; a plastic film anti-escape fence is set up around the paddy field ridge, and the base of the fence is 15 cm into the soil, 40 cm above the field ridge; A 60-mesh filter tulle is set at the water inlet.

[0027] b) Preparatory work before planting: 10 days before direct seeding or transplanting of rice, thoroughly clean and disinfect the entire paddy field after pulping with quicklime. The amount of quicklime is 1...

Embodiment 2

[0034] A kind of method that the present invention proposes the paddy field culture of red crayfish, comprises the following steps:

[0035] a) Field engineering transformation of paddy fields: After selecting paddy fields, use the winter slack season to trim the surface of the paddy fields and excavate the shrimp ditch. The field ridge has a trapezoidal cross-section, with a bottom width of 1.0m and a top width of 0.6m. A 60-mesh filter tulle is set at the water inlet.

[0036] b) Preparatory work before planting: 10 days before rice direct seeding or transplanting, thoroughly clean and disinfect the entire paddy field after pulping with quicklime. The amount of quicklime is 180 kg / mu; The dosage is 300kg / mu of farmyard manure and 30kg / mu of phosphate fertilizer. The base fertilizer is evenly spread on the field surface and plowed and raked evenly with a machine; plant Elodea, water peanut and other aquatic plants in the shrimp ditch, plant a family every 2m, and distribute ...

Embodiment 3

[0043] A kind of method that the present invention proposes the paddy field culture of red crayfish, comprises the following steps:

[0044] a) Field engineering transformation of paddy fields: After selecting paddy fields, use the winter slack season to trim the surface of the paddy fields and excavate the shrimp ditch. The shrimp ditch is L-shaped, 2.2m wide and 1.0m deep, accounting for 10% of the total area of ​​the paddy field; The field ridge has a trapezoidal cross-section, with a width of 1.0m at the bottom and 0.45m at the top, and the top is 1.0m higher than the field plane; an asbestos tile anti-escape fence is set up around the ridge of the paddy field, and the base of the fence is 15 cm into the soil and 45 cm higher than the field ridge; A 60-mesh filter tulle is set at the water inlet.

[0045] b) Preparatory work before planting: 10 days before rice direct seeding or transplanting, thoroughly clean and disinfect the entire rice field after pulping with quicklim...

Abstract

The invention discloses a method of rice field breeding of cherax quadricarinatus. The method includes the following steps that a, rice field engineering modification is conducted; b, preparation workis conducted before planting and breeding; c, rice variety selection and planting are conducted; d, cherax quadricarinatus seeds are selected and put; e, rice daily management is conducted; f, breeding management is conducted on cherax quadricarinatus; g, rice harvesting and cherax quadricarinatus group capturing are conducted. According to the method of rice field breeding of cherax quadricarinatus, the biological habit of cherax quadricarinatus and the features of rice planting are used for realizing co-existence of cherax quadricarinatus and rice, meanwhile, vetiver grass, sesame, perennial coreopsis and clovers are planted on field ridges and used for insect pest biological prevention and control over rice and landscaping, high-quality rice products and high-quality cherax quadricarinatus are obtained, and the comprehensive benefits of a rice field are effectively increased.

Description

technical field [0001] The invention belongs to the technical field of planting and breeding symbiosis, and in particular relates to a method for cultivating red-clawed crayfish in paddy fields. Background technique [0002] Red Claw Crawfish (Latin name: Cherax quadricarinatus von Martens), also known as "Australian freshwater lobster", is native to Australia and is one of the freshwater economic shrimp species. The body color of this shrimp is brown-green, and there is a membranous bright red band on the top of the outer claw, which is beautiful and beautiful, so it is also known as red claw crayfish. The shrimp lives in fresh water all its life, is omnivorous, has a fast growth rate, a high survival rate and strong disease resistance, strong adaptability, low oxygen resistance, tender meat, delicious taste, and long-distance transportation. , can be listed fresh, high market price and other characteristics. Although my country introduced trial breeding from Australia ...
