Description

Technical Field

[0001] The invention belongs to the technical field of plant sowing, and in particular relates to a submerged plant seed bag device. Background Art

[0002] Generally, when treating eutrophic water bodies, the water purification function of aquatic plants is often used to purify the water bodies. Among them, submerged plants are an important component of lake ecosystems and are of great significance to maintaining lake ecosystems and controlling lake eutrophication.

[0003] At present, most submerged plants are suitable for living in shallow water areas of 1.0-1.5m, such as coastal wetlands. In the existing technology, when sowing submerged plants, most of them adopt the method of directly throwing seeds into the water or adopting the planting method that workers take a boat and fork the stems of the plants and fork them into the water. The former planting method has a low seed germination rate, and the seeds are easy to flow with the water flow, and the growth position is relatively random. The latter planting method is time-consuming and labor-intensive, and is not suitable for use in large-scale planting. Moreover, it can only be planted through the rhizomes of plants in a targeted manner, and cannot be planted directly with seeds. Summary of the invention

[0004] The object of the present invention is to provide a submerged plant seed bag device in view of the above problems.

DETAILED DESCRIPTION

[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This embodiment provides a submerged plant seed bag device, combined with Figure 1 and Figure 3As shown, the device body 2 includes a device body 2 for storing nutrient soil 1 mixed with seeds, the device body 2 includes a base 21, the upper surface of the base 21 has a culture groove 22 recessed into the inside of the base 21, the nutrient soil 1 is located in the culture groove 22, and also includes two oppositely arranged cover mechanisms 23 with arc-shaped sides, one end of the cover mechanism 23 is rotatably connected to the edge of the base 21, and the other end is provided with a snap-on mechanism 24. The cover mechanism 23 is rotated, and the cover mechanism 23 can be snap-fitted with another cover mechanism 23 through the snap-on mechanism 24. The two cover mechanisms 23 enclose a growth cavity 25 connected to the culture groove 22, and the growth cavity 25 is located directly above the culture groove 22, so as to facilitate the growth of submerged plant seeds into the growth cavity 25 after germination.

[0028] The nutrient soil 1 includes 40 parts by mass of humus soil, 15 parts of seaweed mud, 30 parts of coconut bran, 15 parts of sawdust, 8 parts of animal manure and 13 parts of slow-release fertilizer. The animal manure can be easily obtained poultry manure, such as chicken manure, duck manure and goose manure.

[0029] When the present invention is used, submerged plant seeds, such as duckweed seeds, Vallisneria seeds, black algae seeds, foxtail algae seeds, Potamogeton combi seeds, and crinum seeds, are mixed evenly with dry nutrient soil 1, and the mixed seeds are placed in a culture tank 22, and the cover mechanism 23 is rotated so that the cover mechanism 23 is mutually engaged and fixed, and the seed bag device is placed as a whole in the water of the coastal wetland, waiting for the submerged plant seeds in the nutrient soil 1 to germinate. The present invention utilizes a seed bag device with a culture tank 22 that can hold the nutrient soil 1 to realize the planting of submerged plants, thereby improving the germination rate of submerged plant seeds sown in the coastal wetland. At the same time, this method is suitable for the planting of seeds or rhizomes, and is suitable for use in large-scale planting.

[0030] Preferably, the base 21 includes a skeleton layer 211 and a water-absorbent resin layer 212 located on both sides of the skeleton layer 211, the water-absorbent resin layer 212 is in contact with the culture trough 22, the water-absorbent resin layer 212 can be made of a polymer water-absorbent resin, and the skeleton layer 211 can be made of a commonly used plastic material or alloy material. The base 21 of the present invention is composed of a water-absorbent resin layer 212, a skeleton layer 211 and a water-absorbent resin layer 212 in sequence, and has a good water-locking and moisturizing effect. It can also supply water to submerged plants for a long time under drought conditions, thereby improving the survival rate of submerged plants in harsh environments.

[0031] Combination Figure 1 and Figure 2As shown, the cover mechanism 23 includes an arc segment 28, and each end of the cover mechanism 23 is provided with a horizontal positioning rod 26 and a vertical positioning rod 27 that are interconnected. The horizontal positioning rod 26 and the vertical positioning rod 27 are both connected to the arc segment 28. Rotating the cover mechanism 23 can make the horizontal positioning rod 26 fit against the upper edge of the base 21, and rotating the cover mechanism 23 can make the vertical positioning rods 27 of the two cover mechanisms 23 fit against each other, so that it can be ensured that the cover mechanism 23 can be rotated to a suitable position when in use.

[0032] Preferably, the side wall of the base 21 close to the vertical positioning rod 27 has a locking hole 11 that passes through the side wall of the base 21. The locking holes 11 on the side walls on both sides of the base 21 are symmetrically arranged. The vertical positioning rod 27 can be locked to the surface of the base 21 by passing an iron wire through the locking hole 11 to prevent the cover mechanism 23 from being opened when the seed package device is placed in water.

[0033] like Figure 2 As shown, a plurality of connecting rods 29 are provided between the vertical positioning rod 27 and the arc segment 28. The connecting rods 29, the vertical positioning rod 27 and the arc segment 28 enclose a horizontal flow groove connected to the growth cavity 25. The arc segment 28 is provided with a plurality of vertical flow holes 30 passing through the arc segment 28. The vertical flow holes 30 are connected to the growth cavity 25. In this way, water still flows in all directions on the surface of the nutrient soil 1, which is similar to the real aquatic growth environment and is more in line with the natural growth environment. At the same time, it also facilitates the exchange of water and gas between the inside and outside of the seed bag device, which is beneficial to the germination of submerged plant seeds.

[0034] Combination Figure 1 and Figure 2 As shown, the snap-fit ​​mechanism 24 includes a dovetail groove 241 and a snap-fit ​​block 242 that can be snapped together. The dovetail groove 241 and the snap-fit ​​block 242 are respectively arranged at relative positions of the two cover mechanisms 23. Rotating the cover mechanism 23 can make the snap-fit ​​block 242 located in the dovetail groove 241. After snapping, the two cover mechanisms 23 can be prevented from separating in the horizontal direction.

[0035] Combination Figure 3 and Figure 4As shown, the inner surface of the base 21 near one end of the growth cavity 25 has a groove 4 for accommodating the edge of the plastic film 3 and recessed toward the inside of the side wall, the bottom surface of the groove 4 and the side wall of the base 21 form a pressing step 5, the nutrient soil 1 presses the end of the plastic film 3 on the pressing step 5, the plastic film 3 covers the nutrient soil 1, and the two ends of the groove 4 have rectangular convex ridges 6, the outer surface of the plastic film 3 is fitted with the side of the convex ridge 6, the edge of the plastic film 3 is pressed by the nutrient soil 1, and the plastic film 3 at the center position covers the surface of the nutrient soil 1, so that in the process of sinking the seed bag device into the water, the nutrient soil 1 can be prevented from diffusing into the water, and the convex ridge 6 can change the direction of the water pressure on the corners of the plastic film 3, so that the plastic film 3 is less likely to separate from the nutrient soil 1 during the process of sinking the seed bag device into the water.

[0036] Combination Figure 2 and Figure 3 As shown, it also includes a pipe splicing piece 7 fixedly connected to the cover mechanism 23 and one end of which passes through the cover mechanism 23. The pipe splicing piece 7 is a hollow semicircle. The pipe splicing piece 7 is arranged at the relative positions of the two cover mechanisms 23. Rotating the cover mechanism 23 can make the two pipe splicing pieces 7 fit together to form a guide pipe 8. The guide pipe 8 is located directly above the plastic film 3. One end of the pull wire 9 is fixedly connected to the plastic film 3, and the other end passes through the guide pipe 8 and extends to the outside of the cover mechanism 23. After the seed bag device sinks to the specified position, the plastic film 3 only needs to be pulled out through the guide pipe 8 by pulling the pull wire 9, thereby achieving contact between the nutrient soil 1 and the water. The end of the pull wire 9 located outside the cover mechanism 23 is provided with a limiting expansion portion 10. The diameter of the limiting expansion portion 10 is larger than the diameter of the guide pipe 8. The expansion portion 10 can prevent the pull wire 9 from falling into the guide pipe 8 as a whole.
