Description

Technical Field

[0001] The invention relates to shrimp and crab farming, and in particular to an aquatic grass planting device suitable for shrimp and crab farming ponds. Background Art

[0002] A waterweed planting positioning device CN201922395927.0 discloses a waterweed planting positioning device, which uses a method of moving the breeding trough up and down to solve the problem that when the transparency of the water body is low, the waterweed cannot get light and gradually dies, and the waterweed is displaced by wind and waves, and the roots of the waterweed leave the soil layer and die. This patent requires that the waterweed be planted in a fixed device, and the depth of the waterweed be controlled to solve the problem that the waterweed cannot see the light. This method is feasible for landscape waterweed and a small amount of waterweed. When planting in large quantities, it not only requires high construction costs but also maintenance costs, which cannot meet the needs of breeding production. It is also easy to cause the death of waterweed in hot weather, so it is not suitable for shrimp and crab farming.

[0003] Waterweed planting frame CN202021943378.2 discloses a waterweed planting frame, in which a sponge block is embedded on the top of a steel frame, and a plurality of through holes are formed in the sponge block to fix the waterweed in the through holes. While fixing the waterweed, the roots of the waterweed are rooted in the waterweed mud, which is beneficial for the waterweed to absorb nutrients, promotes the development of the waterweed root system, and thus promotes the growth of the entire plant. This patented technology fixes the waterweed in the sponge block, which is suitable for the planting of a small number of small clumps of ornamental waterweed, but cannot be used for shrimp and crab farming, which requires large clumps of large-scale planting in water bodies. Summary of the invention

[0004] The invention proposes an aquatic grass planting device suitable for shrimp and crab breeding ponds, aiming to solve the problem of aquatic grass planting and maintenance in shrimp and crab ponds.

When the aquatic planter is planted, each claw penetrates into the bottom of the pond, the aquatic plant blocks are attached to the frame, and the fixing nails pass through the frame and nail the frame to the bottom of the pond.

[0016] Experiment 1, from March to October 2024, a total of 12 Chinese mitten crab breeding ponds were tested. The waterweed planter used: the frame is a 30 cm diameter circle with a grid spacing of 10 cm. The frame is a solid flat shape with a width of 1 cm; the fixing nail is 30 cm long and the anti-drop cap is 2 cm in diameter. The light guide used: the light collector is polygonal, made of acrylic material, with a diameter of 30 cm; the optical fiber is 1 meter long, 0.5 cm in diameter, and there are 30 pieces.

[0017] Divided into: experimental group, group without light guide, control group, the experimental group, using water grass planter and guide device (water grass planting device of the present application); the group without light guide, using water grass planter but without light guide; the control group, ordinary planting (no water grass planter and guide device); After 8 months of breeding, the average root breaking and floating rate of the control group reached 52.35%; in the group without light guide, the average proportion of root breaking and floating was 16.09%; the average root breaking and floating rate of the experimental group was 4.14%. After supplementary light, the aquatic plants grew well, the vitality of the aquatic plants was high, the effect of purifying water quality was better, and the crab farming effect was significant.

[0018] The growth effect of aquatic plants is as follows: Pond No. Area / mu Number of grass balls planted Number of root-cut aquatic plants Proportion of root-destroyed aquatic plants / % Experimental Group 5 360 11 3.05 Experimental Group 6 410 19 4.63 Experimental Group 8 540 21 3.89 Experimental Group 12 860 43 5.00 No light guide assembly 14 980 93 9.49 No light guide assembly 6 380 83 21.84 No light guide assembly 8 510 69 13.53 No light guide assembly 5 400 78 19.50 Control group 7 460 330 71.74 Control group 9 640 258 40.31 Control group 13 920 425 46.19 Control group 20 1200 614 51.17 In experiment 2, the river was 1-2 meters deep and naturally grew water plants such as waterweed and elodea. Starting from June, the water plants tended to die and rot, and the water quality of the river was poor.

The frame is a solid flat shape with a width of 1 cm; the fixing nail is 30 cm long and the anti-drop cap has a diameter of 2 cm. The light guide used: the light collector is polygonal, made of acrylic material, with a diameter of 40 cm; the optical fiber is 1.5 meters long, 0.2 cm in diameter, and there are 50 of them.

[0020] A waterweed planter was placed in the middle of the river. The water level in the river fluctuated, from about 1 meter in May to June to about 1.5 meters in July to August. The water sometimes flowed and sometimes remained still, and the flow rate was slow when it flowed. After observation experiments from May to September, waterweeds around the waterweed planter grew vigorously.

[0021] Experiment 3 (light guide effect test of light guide), The water depth of the experimental environment pond is 1 meter. The light intensity at the outlet is measured with a illuminometer during the summer day. The light collector is polygonal, made of acrylic material, with a diameter of 30-50 mm; the diameter of the optical fiber is 5 mm.
