Crayfish (Procambarus clarkii) is an aquatic animal belonging to the family Crustacea, the order decapod and the family Cricedaceae, and is popular with people because of delicious meat flavor. Loach (Oriental Weatherfish) belongs to the genus Misgurni of the family Misgurnaceae, and has tender meat, delicious taste and rich nutrition. The microorganisms and pests produced in the production process of the rice are grains of crayfish, and the excrement of the crayfish is fertilizer of the rice and can feed back the growth of the rice.

| Comparative example 5 | 598.71 | 248.03 | 192.70 |
The results show that compared with the comparative examples 1-3, the rice field, crayfish and loach coupled breeding method provided by the invention has the advantages that the growth is mutually promoted, the yield of crayfish, loach and rice is remarkably improved, the loaches and crayfish are easy to capture, and the capture amount per mu is remarkably improved.
The average specification of crayfish and loach is as follows 2:
| average loach size (g/tail) | Average crayfish (g/tail) | |
| Example 2 | 55.6 | 51.2 |
| Example 3 | 54.2 | 50.8 |
| Example 4 | 54.8 | 50.4 |
| Comparative example 1 | 50.1 | 47.6 |
| Comparative example 2 | 51.9 | 48.7 |
| Comparative example 3 | 53.3 | 50.1 |
| Comparative example 4 | 51.6 | 48.4 |
| Comparative example 5 | 52.9 | 49.2 |
The results show that compared with the comparative examples 1-3, the coupled breeding method for the rice field, the crayfish and the loaches promotes the growth of the crayfish and the loaches, and obviously improves the specifications of the crayfish and the loaches.
In comparative example 1, the crayfish a area, the loach area, and the crayfish B area were not provided according to the present invention, and the specifications and the yields of crayfish and loach were significantly reduced, and the rice yield was also significantly reduced. Comparative example 2 loach seedlings and crayfish were put in faster after the seedlings were planted, the effect of breeding was also significantly reduced, and mutual growth promotion was not facilitated. The crayfish area A, the loach area and the crayfish area B are arranged, so that the crayfish and the loach are mutually promoted to grow and breed, the rice can absorb nutrients, the loach and the crayfish can be captured easily, the specifications and the capturing amount of the crayfish and the loach are obviously improved, and the rice acre yield is improved. Moreover, the loach seedlings and the crayfishes are respectively put in the rice field at certain time intervals after the seedlings are planted, so that the growth of rice is facilitated, and the growth of the crayfishes and the loaches is promoted better.
Comparative example 3 the yield of crayfish, loach and rice was reduced without the fertilizer I formulated in the present invention. According to the invention, potassium chloride, calcium superphosphate and ammonium sulfate are combined with passion fruit shell leavening, the proportion is optimized, the disease resistance of rice is improved, the growth is promoted, the growth of crayfish and loach is promoted, and the planting and breeding effect is effectively improved.
Comparative example 4 the compound microbial inoculum prepared by the invention is not adopted, the output of crayfish, loach and rice is obviously reduced, and the specifications of the crayfish and loach are also reduced. And the comparative example 5 has short time for spraying the composite microbial inoculum twice, reduces the spraying amount each time, and obviously reduces the effect. By adopting the compound microbial inoculum with a certain proportion, the disease resistance of the crayfishes and the loaches is synchronously improved, the growth of the crayfishes, the loaches and the rice is promoted, and the yield of the crayfishes, the loaches and the rice is obviously improved. In addition, the invention sets certain spraying interval time, preferably spraying amount each time, and fully exerts the efficacy of the composite microbial inoculum.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the scope of the present invention.
