Detailed Description

The following embodiments are described in detail with reference to the accompanying drawings, so that how to implement the technical features of the present invention to solve the technical problems and achieve the technical effects can be fully understood and implemented.

The invention discloses a construction method of a lobster autumn breeding greenhouse based on a rice and shrimp comprehensive breeding mode, which comprises the following steps in some embodiments:

in step 1, referring to fig. 1 to 6, a paddy field 1 includes a plurality of paddy field units 2, and ridges 3 surround the periphery of the paddy field 1. Corners are arranged between four corners of the paddy field 1 and the ridges 3, wherein 1-4 corners are provided with the shrimp collecting ponds 4, namely, one corner of the shrimp collecting pond 4 can be arranged, and the shrimp collecting ponds 4 can also be arranged at 4 corners as shown in figure 1.

One or more field ditches 5 are arranged between the adjacent paddy field units 2, a circulating ditch 6 is arranged between the paddy field units 2 and the ridges 3, and the field ditches 5, the circulating ditch 6 and the shrimp collecting ponds 4 are communicated. The ratio of the ditch and the pit of the comprehensive rice and shrimp planting field block is less than 10 percent. Further, the depth of the shrimp collecting pond 4 is larger than that of the field ditch 5 and the circulating ditch 6.

And 2, arranging a first arched shed 7 on the field ditch 5 and the circulation ditch 6, constructing in the middle and last ten days of 11 months, and removing in the next year in 3 months. The bottom edge of the covering film of the first arched shed 7 at least extends into the water surface for 2cm, so that the temperature in the small environment is kept to be over 13 ℃, and the lobster growth is suitable.

In some other embodiments, during cold winter conditions, a second arched shed may be installed in the first arched shed 7, and the bottom edge of the covering film of the second arched shed is not higher than the water surface. Further, the bottom edge of the covering film of the second dome is flush with the water surface to ensure that the temperature in the small environment is maintained above 13 ℃.

And 3, arranging a vertical column-shaped first warm shed 8 on the shrimp collecting pond 4, wherein the height of the first warm shed 8 is 2.5cm, and the side surface of the first warm shed 8 is provided with an inlet and an outlet which are communicated with the field ditch 5 and the circulating ditch 6, so that the crayfish can enter the shrimp collecting pond 4. The first greenhouse 8 is built in the middle and last 11 months and removed in the second year, 3 months. The bottom edge of the covering film of the first greenhouse 8 at least extends into the water surface for 2cm, so that the temperature in the crayfish environment is kept to be over 13 ℃ to be suitable for the growth of the crayfish, and the movement of the crayfish is not influenced.

In some other embodiments, a second greenhouse can be erected in the first greenhouse 8 when the winter is particularly cold, and the bottom edge of the covering film of the second greenhouse is not higher than the water surface. Furthermore, the bottom edge of the covering film of the second greenhouse is flush with the water surface, so that the temperature in the crayfish environment is kept to be over 13 ℃ to be suitable for the growth of the crayfish and the movement of the crayfish is not influenced.
