[0020] The utility model will be further described in connection with the drawing and specific implementation example:

[0021] Specific implementation example such as Figure 1As shown, the utility model relates to a kind of afforestation nursery stock water supply device, for continuously supplying water to the root of nursery stock, including water storage container 1, extension pipe 2 and water-absorbing strip 3, extension pipe 2 is connected with water storage container 1 and extends upwards, the upper end of extension pipe 2 is higher than the top of water storage container 1, the upper end of water-absorbing strip 3 is inserted in extension pipe 2 and blocks extension pipe 2, reduce silt into water storage container 1 so that moisture escapes outward;Water-absorbing strip 3 is in contact with the lateral root 8 of nursery stock, and water-absorbing strip 3 slowly releases moisture around the lateral root 8 of nursery stock by capillary action, so that the lateral root 8 can continuously absorb moisture, meet the moisture demand of nursery stock in the early afforestation;On the other hand, the lateral root 8 does not need to be directly inserted into water storage container 1, to prevent the lateral root 8 from being soaked for a long time, effectively avoid lateral root 8 waterlogged root rot;The lower end of water-absorbing strip 3 is in contact with the bottom of water storage container 1, and the lower end of water-absorbing strip 3 is in contact with the bottom of water storage container 1, which can fully absorb the water in water storage container 1 and supply to nursery stock, effectively prevent the lateral root 8 from being unable to fully absorb the moisture in water storage container 1 when the growth is limited.

[0022] Preferably, water-absorbing strip 3 is made of soft and water-absorbing material such as cotton or sponge, and cotton is preferred in the embodiment.

[0023] The upper end of extension pipe 2 is higher than the top of water storage container 1, which prevents the water in water storage container 1 from flowing out, and also helps to increase the burial depth of water storage container 1, reduce the micro-greenhouse effect in water storage container, and avoid high temperature stress on the root.

[0024] Preferably, a suitable lateral root 8 is selected from the afforestation nursery stock, and the lateral root 8 is inserted into extension pipe 2 and in contact with water-absorbing strip 3, so that water-absorbing strip 3 can accurately deliver moisture to the lateral root 8 after being inserted into extension pipe 2 and forming close contact with the lateral root 8. The nursery stock is planted according to conventional planting measures, and water storage container 1 and extension pipe 2 are buried in afforestation hole, and the root of nursery stock cannot be exposed to the surface of afforestation hole.

[0025] Preferably, water storage container 1 is also connected with water supplement pipe 4, the upper end of water supplement pipe 4 is exposed to the ground, and the upper end of water supplement pipe 4 is provided with pipe cover 5, so that water supplement pipe 4 can be used to regularly supplement water in water storage container 1 for the lateral root 8 of nursery stock to absorb, which can effectively reduce water evaporation caused by direct irrigation, improve the utilization rate of water by nursery stock, and greatly reduce the frequency of manual irrigation. After the nursery stock grows, the position of water supplement pipe 4 can be used to dig down to the position of water storage container 1, and the water storage container 1 is taken out, which reduces environmental pollution.

[0026] Preferably, water storage container 1 is a discarded mineral water bottle, and the lower end of extension pipe 2 is connected with the bottle opening of the mineral water bottle, which realizes the recycling of discarded plastic bottles and reduces the afforestation cost. A water supplement hole is formed on the bottle of the mineral water bottle, and water supplement pipe 4 is inserted into the water supplement hole and integrated by hot melting or gluing.

[0027] Preferably, the mineral water bottle is placed horizontally in the planting hole. The extension tube 2 is a curved tube with its opening facing upwards. The total length of the extension tube 2 is approximately 8-10 cm. The horizontal end of the extension tube 2 is the lower end, which connects to the mouth of the mineral water bottle. The upper end of the extension tube 2 extends upwards towards the mineral water bottle to prevent water from flowing out naturally. The absorbent strip 3 is approximately 15 cm long and extends from the upper end of the extension tube 2 into the bottom of the mineral water bottle when it is placed horizontally.

[0028] The lower end of the extension tube 2 is provided with an internal thread that matches the mouth of the mineral water bottle. The extension tube 2 is directly screwed into the mouth of the mineral water bottle using the internal thread, which makes it easy to assemble and disassemble, provides good sealing performance, and prevents water leakage.

[0029] Furthermore, such as Figure 2 , Figure 3 As shown, the upper end of the extension tube 2 forms a set of arc-shaped pieces 6 spaced circumferentially by means of a notch. The arc-shaped pieces 6 are sealed by wrapping with a film 7 or connected to the film 7 in sequence to form a ring structure, preventing soil from entering the extension tube 2 and the water storage container 1. The upper end of the water-absorbing strip 3 has a T-shaped structure that is wider at the top and narrower at the bottom or an inverted L-shaped structure. The large diameter part of the water-absorbing strip 3 blocks the extension tube 2, and the small diameter part of the water-absorbing strip 3 overlaps with the notch in height. In this embodiment, a layer of film 7 is wrapped around the circumference of the extension tube 2 on the outside of the arc-shaped pieces 6. The arc-shaped pieces 6 provide support for the film 7, so that the film 7 forms a ring structure. The upper part of the arc-shaped pieces 6 contacts the large diameter part of the water-absorbing strip 3, and the lower part of the arc-shaped pieces 6 overlaps with the small diameter part of the water-absorbing strip 3 in height. As the seedlings grow, the lateral roots 8 gradually thicken. The lateral roots 8 compress the film 7 and penetrate the film 7 into the surrounding soil, realizing the natural expansion of the root system.

[0030] Preferably, the film 7 can be a biodegradable film, such as a starch film, which helps reduce plastic pollution in afforestation. The starch film is easy for roots to penetrate during decomposition, and the opening at the upper end of the extension tube 2 is exposed after decomposition, which facilitates the roots to grow into the soil.

[0031] This utility model relates to a water supply device for afforestation seedlings. Workers can select water storage containers 1 of different capacities according to the actual terrain and soil conditions. After the water storage container 1 is filled with water, it can be buried once or water can be added to the water storage container 1 in the middle to maintain the absorption of afforestation seedlings for more than 15 days. There is no need for frequent manual irrigation, and the water utilization rate in the water supply device is close to 100%. It can continuously supply the water required for the growth of seedlings in the early stage when the root system is not developed, which significantly improves the survival rate of seedlings, saves labor and water, and has obvious economic advantages.
