Problems solved by technology

[0002] The main disadvantages of the existing shrimp-rice continuous cropping technology are: 1. After the rice is harvested, the paddy field does not leave Procambarus clarkii, and before the paddy is planted again, the paddy field needs to be plowed and plowed; 2. Intermittent breeding, the utilization of farmland 3. The fertility of the farmland during the rest period is reduced; 4. The eggs are easy to reproduce, which brings hidden dangers of plant diseases and insect pests to the rice; 5. Recultivation after a period of time intermittently changes the living and breeding environment of the shrimp, and the yield is low; 6. The rice field structure is not conducive to the reproduction and growth of shrimp

Embodiment 1

[0032] Example 1: Such as figure 1 , 2 Shown is a basic embodiment of the invention. A rice field ecological planting method, which is a shrimp-rice co-cropping method in which Procambarus clarkii is cultured and rice planted in a circular manner in a rice field. The steps include: paddy field preparation, shrimp seed feeding, adult shrimp feeding, rice cultivation, paddy field Management and harvesting of adult shrimp, and retention of broodstock; the steps described are specifically:

[0033] A, paddy field preparation: include paddy field selection and construction, wherein paddy field ring ditch 5 is disinfected and planted grass after paddy field ring ditch 5 is completed;

[0034] B. Dropping of shrimp seeds: including the first throwing and subsequent retention of seedlings; when putting in, treat the shrimp seeds first, then evenly take points on the field surface 4, and finally put the shrimp seeds lightly into the shallow water area where the points are taken or ...

Embodiment 2

[0040] Embodiment 2, It is a further example. The difference from Example 1 is that the paddy field has sufficient water sources, no pollution to the water body, no drying up in the dry season, no flooding in the rainy season, good water retention performance, loamy soil, no silting of the bottom fertilizer, and irrigation Easy and convenient one-season rice paddy. The paddy field construction includes: excavating ring ditches 5 , heightening and widening field ridges 2 , improving water intake and drainage systems, and establishing anti-escape nets 3 . The annular ditch 5 is an annular ditch excavated along the inner side of the paddy field ridge 2 with a certain width and depth as a place for Procambarus clarkii to move, escape from the heat, avoid drought and forage; The outlets 6 are respectively located at both ends of the paddy field, wherein the water inlet 1 is on the ridge 2, and the outlet 6 is at the bottom of the ring ditch 5; the anti-escape equipment includes a...

Embodiment 3

[0041] Embodiment 3,It is a further embodiment, and different from Embodiment 2, taking the south of the Yellow River and the middle and lower reaches of the Yangtze River as an example: the shrimp species are released in three stages: the first stage is to release them from the market in March-April. Several kilograms of juvenile shrimps purchased directly from the Internet or artificially caught in the wild; the second price segment is to put broodstock shrimps in July to August, and put in a certain number of broodstock shrimps according to the number of shrimps per kilogram; the third stage During the first month to the last month after the mid-season rice is harvested, according to the specification that each one has a certain length as the shrimp, a certain number of artificially propagated shrimp seedlings are put in. The operation of adding shrimp seeds is as follows: first soak the shrimp seeds in rice field water, then lift them up and put them on hold, then soak th...

Abstract

The invention relates to a rice field ecological planting and breeding method. By means of the rice field ecological planting and breeding method, Procambarus clarkii are bred and rice is planted in a rice field circularly. The rice field ecological planting and breeding method includes the steps of preparation of the rice field, putting of shrimp seeds, feeding of shrimps, rice cultivation, management of the rice field, fishing for shrimps and reservation of parent shrimp seeds. Circular grooves of the rice filed are disinfected and grass is planted in the circular grooves immediately after the circular grooves of the rice field are finished, the reservation of parent shrimp seeds is mainly carried out in the later period of finishing, and parent shrimps are guaranteed to be reserved in the field for breeding parent shrimps of the next year. The rice field ecological planting and breeding method has the advantages that the Procambarus clarkii are reserved after rice is harvested, and the rice field does not need to be turned over, ploughed or harrowed, planting and breeding are jointly carried out continuously and the utilization rate of farmlands is high; fertility of the farmlands is uniform; worm eggs are eaten by the shrimps so that diseases and insect pests of the rice can be prevented; the survival and breeding environment of the shrimps is stable, and the yield is high; the structure of the rice field is favorable for breeding and growth of the shrimps; chemical inorganic fertilizer and chemical pesticides are not used, so that the natural ecological environment is effectively protected.

Description

technical field [0001] The invention relates to a paddy field ecological planting and breeding method, in particular to a shrimp-rice co-cropping method in which Procambarus clarkii is cyclically cultivated and rice is planted in the paddy field, and belongs to the technical field of shrimp-rice breeding and planting. Background technique [0002] The main disadvantages of the existing shrimp-rice continuous cropping technology are: 1. After the rice is harvested, the paddy field does not leave Procambarus clarkii, and before the paddy is planted again, the paddy field needs to be plowed and plowed; 2. Intermittent breeding, the utilization of farmland 3. The fertility of the farmland during the rest period is reduced; 4. The eggs are easy to reproduce, which brings hidden dangers of plant diseases and insect pests to the rice; 5. Recultivation after a period of time intermittently changes the living and breeding environment of the shrimp, and the yield is low; 6. The rice f...
