Embodiment 1

[0020] The polyculture method of red-clawed crayfish and lotus root described in the present embodiment may further comprise the steps:

[0021] Step 1: lotus root field selection and field engineering: select a field with high soil fertility, close to a high-quality water source, easy to drain, flat and fertile, dig a circular breeding ditch around the field, and use the excavated excess soil to reinforce the ridge. Dig a "ten"-shaped ditch between ponds in the middle of the field;

[0022] Step 2: Lotus root planting: The lotus root field used for the first time needs to be disinfected. After the water is drained by the water pump, it is exposed to the sun, then disinfected with quicklime, and filled with water to 30-40cm;

[0023] Step 3: Stocking and management of red crayfish: In early March, a simple greenhouse was built at the water inlet of the breeding ditch for rough labeling of red crayfish. -3cm red crayfish seedlings are introduced into the ditch of the lotus fie...

Embodiment 2

[0027] Present embodiment is object with the lotus root field of 10 mu, and the polyculture method of red claw crayfish and lotus root described in the present embodiment comprises the following steps:

[0028] Step 1: Lotus root field selection and field engineering: select a flat and fertile field with an area of ​​10 mu with high soil fertility. A ring-shaped breeding ditch is dug around the field with a width of 4-5m and a depth of 1-1.2m; a "ten"-shaped ditch between ponds is dug in the middle of the field with a width of 3-4m and a depth of 0.5-0.6m. It communicates with the breeding ditch. The excavated soil is used to reinforce the ridge. The slope ratio of the ridge is 1:2, and the width of the ridge is 2.5m. The ditch can be used as a breeding area for red crayfish to avoid the symbiosis of crayfish and lotus root in the same field and damage the growth of lotus root. Affect benefits. Choose a calcium-plastic plate with strong anti-oxidation ability, and bury it al...

Embodiment 3

[0033] This embodiment takes the lotus root field of 25 mu as the object, and the difference with embodiment 2 is: (1) the length and width of the ditch that needs to be framed properly is 7-8m wide, and the depth is 1-1.2m; The "well" shaped ditch between the ponds is 5-6m wide and 0.5-0.6m deep, and the surrounding ditch is connected with the breeding ditch. The excavated soil is used to reinforce the ridge, the slope ratio of the ridge is 1:2, and the width of the ridge is 2.5m. (2) Due to the increase in the planting area of ​​aquatic plants, it is necessary to remove the dead aquatic plants in the lotus root fields and ditches in time in the middle and late May to avoid water pollution caused by the death of aquatic plants. (3) For large-scale lotus root cultivation, it is possible to dig and build small sheds around the lotus field for temporary breeding. (4) With the increase of the breeding area, a 1.5kw impeller is installed at the four corners and the center of the ...

Abstract

The invention discloses a cherax quadricarinatus and lotus root polyculture method. The method comprises the following steps: step 1, lotus root field selection and field engineering: a field which is high in soil fertility and close to a high-quality water source, facilitates water feed and discharge and is flat and fertile is selected; step 2, lotus root planting: the lotus root field used for the first time needs to be disinfected, after water is pumped by a water pump, the lotus root field is exposed to the sun, then quick lime is used for disinfection, and water is injected to 30-40 cm; step 3, breeding and managing of cherax quadricarinatus: a simple greenhouse is constructed at a water inlet of a breeding ditch at the beginning of March for temporary culture of the cherax quadricarinatus, the greenhouse is removed after lotus roots are planted in the middle ten days of April, and 2500-3000 cherax quadricarinatus seeds of 2-3 cm after temporary culture are introduced into the ditch of the lotus root field per mu; feed is applied on the second day after the shrimps are put; and step 4, harvesting and fishing: manual collection is conducted on the lotus root field from the middle ten days of June to the last ten days of July; ground cage catching and pond cleaning catching are conducted on the cherax quadricarinatus in mid-to-late October. The polyculture method is remarkable in economic benefit effect.

Description

technical field [0001] The invention relates to a method for polyculture of red-clawed crayfish and lotus root, in particular to a method for polyculture of red-clawed crayfish and lotus root with remarkable economic benefits. Background technique [0002] Lotus root is the aquatic vegetable with the largest planting area in my country, and it is planted on a large scale in traditional lotus root producing areas such as the Yangtze River Basin and the Pearl River Basin. Fresh lotus root is rich in various nutrients such as starch, protein, fat, crude fiber, stachyose, fructose and polyphenol compounds, and is an ideal food material. In recent years, the planting area of ​​lotus root has continued to increase with the adjustment of the industrial structure, the price of fresh lotus root has fluctuated greatly, and the economic benefits of simply planting lotus root are low. The interbreeding of other aquatic economic animals in lotus ponds is one of the effective ways to sol...
