Description

Technical Field

[0001] The present invention relates to the technical field of tree breeding and seedling raising, and more specifically to an auxiliary device for direct seeding afforestation in difficult sites and a method for using the device. Background Art

[0002] For a long time, seedling planting has been considered a way to quickly restore forest vegetation. However, since seedlings are easily damaged in the process of cultivation, transportation and planting, the seedlings have a long acclimatization period and reduced root function, resulting in poor adaptability of the seedlings and poor anti-interference ability of the created forest vegetation.

[0003] Seed direct seeding afforestation has the characteristics of keeping the root system of seedlings intact, strong environmental adaptability, and being conducive to retaining excellent individual plants. It is also simple to construct and cost-saving. It is a afforestation method that cultivates long-term, healthy and stable forest communities. However, seed direct seeding afforestation has strict requirements on the site conditions and post-maintenance of the afforestation site. It usually requires afforestation sites with good site conditions, such as moist and loose soil, not too dense shrubs and weeds, and areas where bird and animal damage and other catastrophic factors are not serious. Post-afforestation care and management requirements are high. For example, it is necessary to overcome the fact that seeds are easily harmed by birds and animals, trampled by livestock and destroyed by humans after sowing, and the slow growth of seedlings in the early stage requires a long period of care and management. At present, my country continues to carry out large-scale land greening actions, involving a large part of difficult site afforestation. These afforestation sites are usually located in remote areas with inconvenient transportation and far away from water sources. They are characterized by drought, barrenness, high temperature, etc., which directly threaten the success of direct seeding afforestation.

[0004] Based on this, providing a simple, low-cost, safe and reliable device and method for protecting direct seeding in difficult sites has become a technical problem to be solved urgently, which is of great significance for creating a healthy and stable forest ecosystem and scientifically restoring forest and grass vegetation. The purpose of the present invention is to provide an auxiliary device and method for direct seeding in difficult sites, aiming to solve the problems of incomplete root system and poor adaptability of seedlings in the seedling planting method in difficult sites, as well as technical problems such as susceptibility to bird and animal damage during direct seeding, low water resource utilization efficiency, and difficult management and maintenance.

[0045] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0046] It should be understood that the terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0047] As shown in the figure, the present invention provides an auxiliary device for direct seeding afforestation in difficult sites, comprising: a protector 1, used to prevent seeds and seedlings from being harmed by birds and animals;

[0048] The water supply device is arranged on the protector 1 and is detachably connected to the protector 1. It is used to replenish water for seeds and seedlings in the protector 1 and reduce water evaporation. Because the present invention is usually used for direct seeding afforestation in difficult sites, the water supply device usually uses artificial water replenishment. In areas with abundant water resources, water pipes, water pumps and other equipment can also be used for non-artificial water supply.

[0049] At the same time, the present invention also provides a method for using an auxiliary device for direct seeding in difficult sites. Before implementing the method, the project volume and the sowing pattern (density, distribution) are calculated according to the actual implementation area, and sufficient raw materials (auxiliary devices, seeds, etc. described in the present invention) are prepared in advance; the sowing density and distribution state (forest patches, forest belts, random distribution) are determined according to the local water resources and natural forest distribution patterns. The steps are as follows:

[0050] S1: Make protector 1 and water supply device, prepare seeds, and prepare the land for sowing;

[0051] S2: insert the water supply device into the ground, pull it out after it reaches the designated position, clean the soil in the water supply device, insert it into the soil again until it reaches the designated position, insert the bottom of the protector 1 into the soil, and ensure that the seed is located inside the protector 1, and connect the water supply device to the protector 1;

[0052] S3: Regularly check the growth of seeds and seedlings, and replenish water through the water supply device when there is a lack of water. When the seedlings become lignified, remove the protector 1 and the water supply device.

[0053] The working principle and beneficial effects of the above technical solution:

[0054] (1) Protector 1 prevents seeds and seedlings from being harmed by birds and animals, causing less disturbance to the habitat, which is conducive to the stability of species diversity;

[0055] (2) The water supply device can provide shade, reduce water evaporation and promote seed germination. It is also conducive to the diffusion of water into the deep soil layer, guiding the root system to grow downward and improving drought resistance;

[0056] (3) The pits are prepared to facilitate the flow of runoff into the roots of the seedlings, fully collecting precipitation to promote the survival and growth of independent plants;

[0057] (4) Auxiliary devices can be reused, reducing production costs;

[0058] (5) The required materials are low in cost and easy to purchase, process and transport. The construction operation is convenient, saving time and effort, and can be completed by simple manual operation;

[0059] (6) Later maintenance is simple. Water can be transported deep into the soil by adding water to the water supply device. In addition, fertilizers or soil conditioners can be added to the water supply device to promote root growth.

[0060] Furthermore, in order to optimize the structure and production cost of the protector 1, the protector 1 is a mesh cage with an opening at the bottom, and the water supply device is arranged on the top of the protector 1 and extends into the protector 1. The protector 1 is a closed cylinder with openings at the top and bottom surrounded by a rigid wire mesh sheet, such as Figure 1 As one of the embodiments, the protector 1 can be a rigid wire mesh sheet of 4-8 mesh, 62.8 cm long and 30 cm wide, and two buckles are installed on the wide side, which can be used to form a closed cylinder with a diameter of 20 cm. The protector 1 can be made of stainless steel or plastic, as long as it can be enclosed into a closed cylinder and can support the water supply device, which is arranged at the top opening of the protector 1.

[0061] Further, the water supply device is composed of a water injection device 2 and a water delivery device 3. The water injection device 2 is arranged at the top of the protector 1, and the bottom of the water injection device 2 is connected to the top of the water delivery device 3. The water injection device 2 is composed of a receiving device 21 and a first tube 22. The first tube 22 is arranged at the bottom of the receiving device 21 and extends in a direction away from the receiving device 21. The receiving device 21 is connected to the water delivery device 3 through the first tube 22. The top surface of the receiving device 21 is a concave surface, and the connection point between the first tube 22 and the top surface is located at the lowest point of the concave surface. Usually, the receiving device 21 can be directly placed on the protector 1 that is formed into a closed cylinder. The protector 1 supports the receiving device 21. The protector 1 is located within the coverage of the receiving device 21 (that is, the edge of the receiving device 21 will extend outside the protector 1), so that the receiving device 21 has a larger water receiving area, and when pouring water into the receiving device 21, it will not spill outside the receiving device 21. At the same time, the larger coverage area of ​​the receiving device 21 can shade the seeds and soil in the protector 1, slow down the evaporation rate of water, and improve the survival rate of seed germination and seedling growth.

[0062] Because the receiving device 21 is usually directly placed on the top opening of the protector 1, such as Figure 1As shown, although birds can be prevented from entering the protector 1, some small animals, such as squirrels, can easily climb over the protector 1 and open the receiving device 21 to enter the protector 1. In extreme weather such as strong winds or heavy rains, the receiving device 21 directly placed on the protector 1 is at risk of being overturned and blown away. For this reason, we provide a structural optimization of the receiving device 21.

[0063] In this embodiment, if Figure 5 and Figure 6 As shown, the receiving device 21 can be made of a flexible material with elasticity such as soft silicone, or a soft and foldable structure can be separately provided on the receiving device 21. When in use, after the receiving device 21 is placed on the protector 1, the receiving device 21 is folded so that the portion of the receiving device 21 extending outside the protector 1 can be folded and attached to the outer wall of the protector 1, and the protector 1 can be tightly embraced by its own elasticity, thereby increasing the firmness of the connection between the receiving device 21 and the protector 1.

[0064] Furthermore, the receiving device 21 made of a flexible and elastic material has certain requirements for the diameter of the closed cylinder surrounded by the protector 1. If the diameter of the protector 1 is larger, the width of the "flange" of the receiving device 21 will be reduced, and the radial pressure of the receiving device 21 on the top opening of the protector 1 will also increase, causing the receiving device 21 to fall off from the opening of the protector 1.

[0065] If the diameter of the closed cylinder surrounded by the protector 1 is small, the width of the "flange" of the receiving device 21 will increase, and the water receiving area of ​​the concave surface on the top of the receiving device 21 will be reduced, which is easy to overflow when pouring water. Therefore, we have optimized and adjusted the above implementation method.

[0066] In this embodiment, the receiving device 21 is also made of a flexible material, and may be partially made of a rigid material and partially made of a flexible material. A material that can be shaped, such as a wire, is added to the opening edge of the receiving device 21, and the flexible material is made of a material that is not elastic or has low elasticity, so as to avoid the "flange" from generating a radial force on the opening of the protector 1 after folding, thereby preventing the protector 1 from being "deformed".

[0067] When this embodiment is in use, it is the same as the aforementioned embodiment, and the portion extending outside the protector 1 is also folded. Because a flexible material with no elasticity or low elasticity is selected, the radial force on the protector 1 at the opening is small after folding, and the plastic material at the opening edge of the receiving device 21 is bent so that the "flange" has a protrusion extending toward the center of the protector 1, and the protrusion is pressed into the grid of the protector 1, so that the protrusion can limit the position of the receiving device 21 in the vertical and circumferential directions. Therefore, there are no excessive requirements on the diameter of the closed cylinder formed after the protector 1 is enclosed, and because of the addition of the plastic material, even if the protector 1 is used in inclined areas such as hillsides, the receiving device 21 and the protector 1 can have good firmness.

[0068] Furthermore, the water delivery device 3 is a tubular structure, such as Figure 3 As shown, the top of the water delivery device 3 is connected to the bottom of the first pipe 22. In order to allow the water to diffuse into the deep soil layer, the bottom surface of the water delivery device 3 has a non-zero angle with the horizontal plane, so that the bottom of the water delivery device 3 is a "pointed head" for easy insertion into the soil and transporting water to the deep soil. At the same time, in order to increase the penetration range of water, the side wall of the water delivery device 3 is provided with a plurality of seepage holes 31.

[0069] Furthermore, considering the climate issues in difficult-to-site areas, areas with large temperature differences between morning and evening will form condensed water on the receiving device 21, and most of the condensed water will drip and remain on the soil surface, evaporating as the temperature rises, and only a very small part will seep into the underground soil. In order to reduce the number of times the water supply device is replenished, and also to effectively utilize the condensed water formed by the temperature difference, the bottom of the receiving device 21 is a cone with a larger top and a smaller bottom. Increasing the area of ​​the bottom of the receiving device 21 can form more condensed water, and at the same time, the cone with a larger top and a smaller bottom can effectively guide the condensed water to the outer wall of the first tube 22. In order to allow the condensed water to enter the deep soil from the water delivery device 3, the first tube 22 and the water delivery device 3 are connected and communicated through a collector 4. The collector 4 is tubular, and the inner wall of the collector 4 is provided with a connector 41 connected to the outer wall of the first tube 22, such as Figure 3 and Figure 4As shown, as one of the embodiments of the collector 4, the connector 41 is composed of a second pipe that can be sleeved on the outer wall of the first pipe 22 and a connecting rod. The outer wall of the second pipe is connected to the inner wall of the collector 4 through the connecting rod, so that a gap with a first distance is formed between the outer wall of the first pipe 22 and the inner wall of the collector 4. When the condensed water slides from the receiving device 21 to the outer wall of the first pipe 22, under the action of gravity, the condensed water will enter the water supply device 3 through the gap between the outer wall of the first pipe 22 and the inner wall of the collector 4. The top of the collector 4 is connected to the bottom of the first pipe 22, and a second distance is reserved between the top surface of the collector 4 and the bottom surface of the receiving device 21 to prevent the condensed water from flowing from the outer wall of the collector 4 to the ground. The bottom of the collector 4 is connected to the water supply device 3. Usually, there is a third distance between the bottom surface of the connecting rod and the bottom surface of the collector 4 for the water supply device 3 to be inserted into the collector 4, as Figure 4 shown, the bottom of the collector 4 can also be inserted into the top of the water supply device 3.

[0070] Furthermore, the collector 4 mentioned in the above embodiment is only one of many embodiments. Its advantages are simple production process, easy to carry, and not easily damaged. However, there are certain requirements for the insertion depth of the water supply device 3. When the water supply device 3 is inserted deep into the soil, there may be a situation where the collector 4 cannot connect the first pipe 22 and the water supply device 3 at the same time (that is, one end may be connected while the other end is disconnected). To improve this technical problem, we optimized the collector 4.

[0071] In this embodiment, the collector 4 is still a tubular structure, and the connector 41 is still arranged on the inner wall of the collector 4. The connector 41 is a sheet-like spiral, as Fig.13 shown, the rotation center of the spiral forms a jack for the first pipe 22 to be inserted. There is a fourth distance between the top surface of the spiral and the top surface of the collector 4. The bottom surface of the spiral extends from the bottom of the collector 4 to the outside of the collector 4, and there is a fifth distance between the bottom surface of the spiral and the bottom surface of the collector 4. The fifth distance is equal to the fourth distance, so that two collectors 4 can be inserted into each other up and down, as Fig.12 shown. Through the design of the above structure, no matter how deep the water supply device 3 is inserted into the soil, the first pipe 22 can be connected to it through the collector 4. The spiral structure design of the connector 41 can be used for the connection between two collectors 4, the connection with the first pipe 22, and the connection with the water supply device 3. Usually, the number of connectors 41 is 3, which can play a good connection role and effectively reduce the opening area of the water supply device 3, reducing the evaporation amount of the moisture in the deep soil from the opening of the water supply device 3.

[0072] We provide a specific auxiliary device and a method for using the auxiliary device. In the selected afforestation land, a random scattering or neatly distributed live broadcast mode can be selected according to the land conditions. This embodiment selects the strip live broadcast mode. The method of use is as follows:

[0073] S1: Make a protector 1 and a water supply device;

[0074] In this embodiment, the protector 1 is a closed cylinder with a diameter of 20 cm formed by a rigid wire mesh sheet of 4-8 mesh with a length of 62.8 cm and a width of 30 cm;

[0075] The receiving device 21 is made of iron or stainless steel. The conical top diameter of the bottom of the receiving device 21 is 20.5 cm, the height is 10 cm, the diameter of the connection with the first tube 22 (i.e., the outer diameter of the top of the first tube 22) is 1.2 cm, the outer wall of the first tube 22 is tapered, the outer diameter of the bottom of the first tube 22 is 1.0 cm, and the length is 5 cm;

[0076] The collector 4 adopts the first embodiment and is made of anti-aging plastic. The second tube is 1 cm high and has an inner diameter of 1.1 cm. The collector 4 has an inner diameter of 1.5 cm and a height of 3 cm.

[0077] The water delivery device 3 is a hard tube (stainless steel or anti-aging plastic tube) with an outer diameter of 1.5 cm and a length of 40 cm and open at both ends, and has two water seepage holes 31 at 10 cm and 30 cm from the upper opening.

[0078] S201: Seed preparation. Select native tree species that germinate quickly, have fast seedling growth, strong adaptability and resistance, abundant seed sources, and low prices. Seed pretreatment includes:

[0079] (1) Germination: Deep dormant seeds sown in spring should be germinated in advance so that the seedlings can emerge neatly from the soil that year and fully lignify before the end of autumn, thus achieving the purpose of safe wintering.

[0080] (2) Seed soaking: Seeds that are forced to dormant during spring sowing should generally be soaked to encourage the seedlings to emerge from the soil as quickly and neatly as possible, forming seedlings with deep roots and a high degree of lignification of the above-ground parts, so as to enhance their ability to resist high temperatures, drought and other adverse environmental factors.

[0081] (3) Seed treatment with pesticides: In areas where pests and diseases are serious, seeds should be treated with powders or liquid pesticides before sowing to prevent and control infectious diseases and underground pests.

[0082] S202: Land preparation and sowing. Make a pit with a diameter of 40cm and a depth of 15cm at the sowing location, remove the surrounding weeds, sow the treated seeds at the bottom of the pit and water them sufficiently. The soil covering the seeds is generally 2-3cm thick, and the thickness of the soil covering is adjusted according to the size of the seeds.

[0083] S203: First, fasten the collector 4 to the upper end of the water delivery device 3, and then insert the water delivery device 3 halfway into the soil at a distance of about 2 cm from the seeds. Note that the water delivery device 3 must be inserted into place twice. After the first insertion, take it out, clean the soil in the tube and insert it again to prevent a large amount of soil from clogging the drainage port at the bottom; press the cylinder formed by the protector 1 down 2-3 cm into the soil with the water delivery device 3 as the center, and finally insert the first tube 22 of the receiving device 21 into the second tube of the collector 4, press down to tighten and adjust the position of the protector 1 so that the receiving device 21 presses the protector 1 firmly, and the bottom of the protector 1 is in the soil to form a closed cover.

[0084] S3: Post-maintenance. The growth of seeds and seedlings is monitored regularly. When water is scarce, water is supplemented through the receiving device 21 and the water delivery device 3 to induce root growth. When the seedlings grow and become lignified, the auxiliary device is removed to strengthen fertilizer and water management to promote the rapid growth of independent plants.

[0085] By using auxiliary devices, the protector 1 can prevent seeds and seedlings from being harmed by birds and animals, and has a weaker disturbance on the habitat, which is beneficial to the stability of species diversity; the receiving device 21 can provide shade, reduce evaporation and promote seed germination, and can collect condensed water for utilization and facilitate later water replenishment; the water supply device 3 is conducive to the diffusion of water into the deep soil layer, guiding the root system to grow downward, and improving drought resistance.

[0086] In some other embodiments, fertilizer water and bacterial agents may be added to promote root growth and nutrient circulation. The fertilizer water may be a 15-15-15 compound fertilizer or humic acid fertilizer water of appropriate concentration, and the bacterial agent may be an EM bacterial agent that promotes the decomposition of organic matter.

[0087] After implementation, the seed germination rate reached over 92%, and the preservation rate reached over 90%, achieving regreening in the same year and forming independent plants in the second year. The number of watering times was reduced by more than 30%, the amount of fertilizer used was reduced by 20%, and the cost was reduced by more than 50%. In addition, the root system of the trees grew completely downward, improving drought resistance and soil stabilization function; the number of surface insects increased.
