Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration in arid desertified areas, and in particular to a waterless planting method suitable for water-deficient areas. Background Art

[0002] Land desertification, soil erosion and environmental degradation have become key issues affecting the sustainable development of human society. The desertified area of ​​the world's land accounts for about 30% of the total land area, and it is getting worse with the continuous destruction of the environment and the frequent activities of human beings. The problem of land desertification has seriously threatened the living space of human beings, and the urgent need to improve the ecological environment and the demand for new planting and vegetation restoration technology is becoming stronger and stronger.

[0003] Most of the western part of my country and the "Three Norths" (Northwest, Northeast and North China) are in arid and semi-arid areas, with little precipitation and high evaporation, low survival rate of plant planting and great difficulty in vegetation restoration. Especially in the Inner Mongolia Autonomous Region and other areas in the upper reaches of the Yellow River, due to drought and little rain, the vegetation coverage and planting survival rate are low, which not only causes a lot of wind and sand, forming sandstorm weather, but also causes serious soil erosion. Among them, arsenic sandstone is a landform unique to the Loess Plateau. It is called "the world's most soil erosion" and "environmental cancer", which is extremely harmful to nature, ecology and environment.

[0004] At present, the main method for controlling desertification and soil erosion is biological method. The ecological restoration methods reported in arid and desertified areas include:

[0005] Prior art 1 (Chinese patent CN112868460A) discloses a method for planting sand-dwelling plants based on land desertification control. This planting method adds a protective box to the outside of Haloxylon ammodendron seedlings, effectively preventing the vegetation seedlings from being damaged by mice, thereby improving the survival rate of the vegetation seedlings.

[0006] Prior art 2 (Chinese patent CN112868460A) discloses a method for restoring vegetation on abandoned land in grassland areas and a method for ecological restoration in grassland areas. The technology conducts a background survey of abandoned land in advance, investigates the vegetation types in undamaged areas, establishes a native plant library, selects suitable native plant seeds for sowing based on the native plant library and the purpose of preparation and restoration, and has a good growth effect of native plants. At the same time, fences can effectively prevent animals such as cattle and sheep from trampling on grassland vegetation, which plays a good protective role on grassland vegetation, making the restoration effect of abandoned land vegetation in grassland areas good, which is conducive to repairing the damaged grassland ecosystem and restoring its ecosystem function.

[0007] However, due to the serious sandification and poor water retention in water-scarce areas such as deserts, deserts, and Gobi, the existing reported ecological restoration methods in arid and desertified areas have major defects in practical application. For example, a large amount of rooting water is required after transplanting to the open field, and a large amount of water is also required for later survival and growth, resulting in a large amount of manpower and material resources required for later maintenance, and a low survival rate of vegetation seedlings. Summary of the invention

[0008] The purpose of the present invention is to provide a waterless planting method suitable for water-scarce areas to solve the technical problems existing in the existing ecological restoration technology in arid and desertified areas, such as complicated steps, high maintenance costs and low survival rate of vegetation seedlings.

[0009] The present application provides a waterless planting method suitable for water-scarce areas, and the waterless planting method comprises:

[0010] obtaining vegetation seedlings to be planted;

[0011] Transplanting the plant seedlings into a seedling raising container for seedling raising;

[0012] When the root system of the plant seedling grows out of the seedling container by 0.5 to 6.5 cm, the plant seedling and the seedling container are planted together.

[0013] Furthermore, after planting in the field, the seedlings do not need to be irrigated with water or undergo other cultivation management.

[0014] Furthermore, before the plant seedlings are transplanted into the seedling raising container for raising the seedlings, the plant seedlings have an unearthed height of 10 to 50 cm;

[0015] When the plant seedlings and the seedling raising container are planted together, the length of the root system of the plant seedlings growing out of the seedling raising container is 1 to 5 cm, and the growth height of the plant seedlings is ≥20 cm.

[0016] Furthermore, the parameters of the seedling raising container include: the material is a degradable material, the opening diameter is ≥20 cm, and the height is ≥30 cm.

[0017] Furthermore, the seedling raising container comprises a degradable planting bag, and the degradation time of the degradable planting bag is less than 18 months.

[0018] Furthermore, the types of the vegetation seedlings include at least one of Juncao, Broussonetia papyrifera, Leymus chinensis, Elymus sibiricus, Agropyron ovata, Elymus salsa, Fescue, Leymus foetida, Pseudobulbus salsa, Bromus serrata and Poa sclerophylla.

[0019] Furthermore, the specific process of transplanting the vegetation seedlings into the seedling raising container for seedling raising includes:

[0020] Fill the seedling raising container with seedling raising nutrient soil, then transplant the plant seedlings into the seedling raising container, water them on the same day, and keep the soil moist during the subsequent seedling raising period;

[0021] Wherein, the transplanting depth of the vegetation seedlings is 8~12 cm.

[0022] Furthermore, before transplanting the plant seedlings into the seedling raising container for raising the seedlings, the plant seedlings are pre-treated;

[0023] The pre-treatment comprises: disinfecting and sterilizing the plant seedlings, and then soaking them in rooting water for 1-5 minutes.

[0024] Furthermore, the specific process of planting the vegetation seedlings and the seedling raising container together in the field includes:

[0025] Transferring the plant seedlings and the seedling raising container together into a planting pit, and then covering the planting pit with soil to fill it up;

[0026] The parameters of the planting pit include: depth ≥30 cm, diameter ≥40 cm.

[0027] Furthermore, before planting the vegetation seedlings and the seedling raising container together in the field, the waterless planting method further includes: hardening the seedlings.

[0028] Compared with the prior art, the above solution provided by the embodiment of the present application has at least the following beneficial effects:

[0029] The embodiment of the present application provides a new waterless planting method suitable for water-scarce areas. The waterless planting method first cultivates the vegetation seedlings in a seedling container to a specific growth node (i.e., when the roots of the vegetation seedlings grow 0.5 to 6.5 cm outside the seedling container), and then adopts a water and soil conservation method (i.e., the vegetation seedlings and the seedling container are planted in the ground together) for planting in the ground. After planting in the ground, the vegetation seedlings do not need to be irrigated with water or other cultivation management is required, and the planting of vegetation such as forage grass and sand-dwelling seedlings in water-scarce areas such as deserts, Gobi, etc. can be successfully achieved, which greatly reduces the existing ecological restoration steps in arid and desertified areas and the manpower, material resources and later maintenance costs invested in the entire planting process, and has the characteristics of simple planting operation, low planting cost and high survival rate of vegetation seedlings.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be described clearly and completely below. If the specific conditions are not specified in the embodiments, they are carried out according to conventional conditions or conditions recommended by the manufacturer. If the manufacturer of the reagents or instruments used is not specified, they are all conventional products that can be purchased commercially.

[0036] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to specific embodiments.

[0037] The overall idea of ​​the technical solution provided by the embodiment of the present invention is as follows:

[0038] The present application provides a method for waterless planting suitable for water-scarce areas. Figure 1 As shown, the waterless planting method comprises:

[0039] obtaining vegetation seedlings to be planted;

[0040] Transplanting the plant seedlings into a seedling raising container for seedling raising;

[0041] When the root system of the plant seedling grows out of the seedling container by 0.5 to 6.5 cm, the plant seedling and the seedling container are planted together.

[0042] The embodiment of the present application provides a new waterless planting method suitable for water-scarce areas. The waterless planting method first cultivates the vegetation seedlings in a seedling container to a specific growth node (i.e., when the roots of the vegetation seedlings grow 0.5 to 6.5 cm outside the seedling container), and then adopts a water and soil conservation method (i.e., a method of planting the vegetation seedlings and the seedling container together in the ground, or a water and soil conservation method) for ground planting. After ground planting, the vegetation seedlings do not need to be irrigated with water or other cultivation management is performed, and the planting of vegetation such as forage grass and sand-dwelling seedlings in water-scarce areas such as deserts, Gobi, etc. can be successfully achieved, which greatly reduces the existing ecological restoration steps in arid and desertified areas and the manpower, material resources and later maintenance costs invested in the entire planting process, and has the characteristics of simple planting operation, low planting cost and high survival rate of vegetation seedlings.

[0043] In the present application, the methods for obtaining the seedlings of vegetation to be planted include directly purchasing the seedlings of vegetation that have been bred and unearthed and, based on the existing disclosed breeding and seedling raising techniques and actual factors such as the vegetation to be bred, breeding land and planting time, taking appropriate measures according to local conditions, selecting appropriate breeding and seedling raising time and seedling raising matrix, breeding and raising seedlings of the vegetation to be planted by themselves, and obtaining the seedlings of vegetation to be planted.

[0044] In some specific embodiments, the specific process of obtaining the vegetation seedlings to be planted may include: breeding and raising vegetation seeds such as Juncao and Porphyry to be planted in a heat-insulating cultivation greenhouse. The nutrient medium for breeding and raising seedlings can be selected from farmland rot such as pig manure, cow manure, sheep manure, chicken manure, rabbit manure, humus soil, chaff and other farmland rot mixed with the soil. However, it should be noted that before the farmland rot is mixed with the soil, the existing technology can be used to disinfect and sterilize the above-mentioned farmland rot to improve the success rate of breeding and seedling raising. Take an appropriate amount of the above nutrient medium. Generally, it is spread or mixed into the soil layer with a thickness of 1.5~3.5 cm. The temperature in the greenhouse needs to be maintained at about 18~25℃ and the ambient humidity at about 35~50%. The success rate of breeding and seedling raising is relatively high.

[0045] In the present application, the process of transplanting the vegetation seedlings to the seedling container for seedling cultivation can be carried out according to the existing disclosed seedling cultivation technology and the actual factors such as the vegetation to be cultivated, the breeding land and the time of planting in the field, so as to ensure that the root system of the vegetation seedlings to be planted can smoothly grow 0.5~6.5 cm outside the seedling container. In some specific embodiments, in order to save costs, the cultivation matrix in the seedling container can be a mixture of farmland rot such as pig manure, cow manure, sheep manure, chicken manure, rabbit manure, humus soil, chaff, commercially available seedling compound fertilizer and soil, and in terms of mass fraction, the proportion of farmland rot is 40%~50%, the proportion of commercially available seedling compound fertilizer is 3%~5% and the proportion of soil is 50%~60%.

[0046] In the present application, "when the roots of the vegetation seedlings grow out of the seedling container by 0.5 to 6.5 cm" can be understood as the existing part of the roots of the vegetation seedlings (the number of roots can be 4 or more) naturally growing out of the seedling container (including growing out of the surroundings and bottom of the seedling container, etc.), and the length growing out of the seedling container is preferably in the range of 0.5 to 6.5 cm. At this growth node, the root system of the vegetation seedlings is full and healthy, and the vegetation seedlings are planted in the ground together with the seedling container in a water- and soil-conserving manner. The vegetation seedlings can absorb water and nutrients from the surrounding soil by their own ability, and the survival rate of the vegetation seedlings is high. Vegetation seedlings that have not grown roots or have grown roots less than 0.8 cm in length are vegetation seedlings with unhealthy root systems, and have a low survival rate after being planted in the ground; if the length of the roots is too long, the roots will be damaged after being planted in the ground, which is not conducive to the growth of the roots of the vegetation seedlings, thereby affecting the growth and survival of the vegetation seedlings.

[0047] In some specific embodiments, the root length of the vegetation seedlings growing out of the seedling container can be 0.5 cm, 0.6 cm, 0.7 cm, 0.8 cm, 0.9 cm, 1.0 cm, 1.1 cm, 1.2 cm, 1.3 cm, 1.4 cm, 1.5 cm, 1.6 cm, 1.7 cm, 1.8 cm, 1.9 cm, 2.0 cm, 2.1 cm, 2.2 cm, 2.3 cm, 2.4 cm, 2.5 cm, 2.6 cm, 2.7 cm, 2.8 cm, 2.9 cm, 3.0 cm, 3.1 cm, 3.2 cm, 3.3 cm, 3.4 cm, 3.5 cm, 3.6 cm, 3.7 cm, 3.8 cm, 3.9 cm, 4.0 cm, 4.1 cm, 4.2 cm, 4.3 cm, 4.4 cm, 4.5 cm, 4.6 cm, 4.7 cm, 4.8 cm, 4.9 cm, cm, 5.0 cm, 5.1 cm, 5.2 cm, 5.3 cm, 5.4 cm, 5.5 cm, 5.6 cm, 5.7 cm, 5.8 cm, 5.9 cm, 6.0 cm, 6.1 cm, 6.2 cm, 6.3 cm, 6.4 cm, 6.5 cm, etc.

[0048] The waterless planting method provided in the embodiment of the present application can be applied to the planting of vegetation such as forage grass and sand-dwelling seedlings in water-scarce areas such as western my country and the "Three Norths" (Northwest, Northeast and North China). After the vegetation seedlings to be planted are cultivated through this technology, they can be planted directly in the ground. After being planted in the ground, there is no need to invest a lot of manpower, material resources and later maintenance such as watering.

[0049] As an implementation method of an embodiment of the present application, after being planted in the field, the vegetation seedlings do not need to be irrigated with water or undergo other cultivation management.

[0050] The waterless planting method provided in the embodiment of the present application can be directly planted in the ground after the seedlings are cultivated through this technology. After being planted in the ground, the vegetation seedlings can absorb water and nutrients from the surrounding soil by their own ability, without the need to invest a lot of manpower, material resources and subsequent maintenance, which greatly reduces the cost of the entire planting process.

[0051] As an implementation method of the present application, before the plant seedlings are transplanted into the seedling raising container for raising the seedlings, the height of the plant seedlings emerging from the soil is 10 to 50 cm;

[0052] When the plant seedlings and the seedling raising container are planted together, the length of the root system of the plant seedlings growing out of the seedling raising container is 1 to 5 cm, and the growth height of the plant seedlings is ≥20 cm.

[0053] In the present application, the role of selecting a vegetation seedling with an unearthed height of 10 to 50 cm for transplanting is to facilitate the healthy growth of the root system of the vegetation seedling during the subsequent cultivation process in the seedling container, thereby further improving the survival rate of the vegetation seedling during the entire planting process. In some specific embodiments, on the basis of meeting the above-mentioned unearthed height requirements, the unearthed heights of different vegetation seedlings can be specifically selected according to different vegetation types. For example, the unearthed height of forage vegetation seedlings can be 10 to 25 cm (specifically 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 25 cm, etc.), and the unearthed height of tree vegetation seedlings such as seedlings can be 15 to 50 cm (specifically 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 20 cm, 25 cm, 28 cm, 30 cm, 35 cm, 38 cm, 40 cm, 48 cm, etc.).

[0054] In the present application, another growth node determination factor when the vegetation seedlings and the seedling raising container are planted in the field together is that the growth height of the vegetation seedlings is ≥20 cm. This is because this stage belongs to the vigorous growth period of the vegetation seedlings, and they have strong vitality, which is conducive to further improving the survival rate of field planting. If the growth height of the vegetation seedlings is too low, the adverse effect is that the growth and development of the vegetation seedlings are poor, especially the root development of the vegetation seedlings, which cannot withstand the harsh growth environment of water shortage in arid areas after field planting. In the present application, the upper limit of the growth height of the vegetation seedlings is related to the size (such as height and depth) of the seedling raising container and the type of vegetation. Generally speaking, the growth height of the vegetation seedlings does not exceed 2 meters.

[0055] In the present application, when the vegetation seedlings with a root length of 1 to 5 cm outside the seedling container and a growth height of ≥20 cm are planted together with the seedling container, the survival rate of the vegetation seedlings can be further improved. In some specific embodiments, the growth height of the vegetation seedlings can be 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm, 31 cm, 32 cm, 33 cm, 34 cm, 35 cm, etc.

[0056] As an implementation of an embodiment of the present application, the parameters of the seedling raising container include: the material is a degradable material, the opening diameter is ≥20 cm, and the height is ≥30 cm.

[0057] In the present application, the material of the seedling container is a degradable material, such as non-woven fabrics and geotextiles and other currently disclosed degradable and environmentally friendly materials. After it and the vegetation seedlings are planted in the soil, it will not cause harm to the environment and is green and environmentally friendly.

[0058] In this application, the purpose of controlling the opening diameter of the seedling container to be ≥20 cm and the height to be ≥30 cm is to allow the plant seedlings to grow healthily in the seedling container and to make the root system of the plant seedlings more stretched and healthy. Based on the above size requirements, the specific size of the seedling container can be determined according to the characteristics of the plant to be planted, ensuring that the root system of the plant has enough space to grow and can fully absorb the moisture and nutrients of the seedling medium in the seedling container.

[0059] As an implementation manner of an embodiment of the present application, the seedling raising container includes a degradable planting bag, and the degradation time of the degradable planting bag is less than 18 months.

[0060] In this application, the role of selecting a degradable planting bag as a seedling container is, on the one hand, to provide a suitable growth environment during the seedling raising stage of the vegetation seedlings, while utilizing the flexibility of the material of the degradable planting bag itself to provide a suitable growth resistance for the vegetation seedlings to break through the degradable planting bag, so that the vitality of the vegetation seedlings after being planted in the ground is stronger. On the other hand, it is achieved that the vegetation seedlings can be planted in the ground in a way that conserves water and soil, and in the growth stage after the vegetation seedlings are planted in the ground, especially in the early stage after planting in the ground, the water and soil conservation performance of the growth environment around the vegetation seedlings is increased, which is more conducive to the vegetation seedlings being able to absorb nutrients and water from the surrounding environment by their own ability in the future.

[0061] In some specific embodiments, the degradable planting bag may be a non-woven bag, a geotextile bag, or the like.

[0062] The purpose of selecting degradable planting bags with a degradation time of less than 18 months in this application is, on the one hand, to protect the environment; on the other hand, it is beneficial for the roots of vegetation to completely break through the limitations of the planting bags in the subsequent stage of planting, and is more conducive to the vegetation to fully absorb nutrients from the surrounding environment.

[0063] As an implementation example of the present application, the types of vegetation seedlings include at least one of Juncao, Broussonetia papyrifera, Leymus chinensis, Elymus sibiricus, Ice grass, Elymus dahliae, Fescue, Leymus foetida, Psammophila sinensis, Bromus sibiricum and Poa sclerophylla.

[0064] The waterless planting method provided in the embodiment of the present application can be applied to the vegetation that is currently disclosed to grow in water-scarce areas such as deserts, Gobi, etc., and can be reasonably selected according to the actual situation of the place to be planted and grown.

[0065] As an implementation method of the present application, the specific process of transplanting the vegetation seedlings to the seedling raising container for seedling raising includes:

[0066] Fill the seedling raising container with seedling raising nutrient soil, then transplant the plant seedlings into the seedling raising container, water them on the same day, and keep the soil moist during the subsequent seedling raising period;

[0067] Wherein, the transplanting depth of the vegetation seedlings is 8~12 cm.

[0068] In the present application, the purpose of controlling the transplanting depth of the vegetation seedlings to 8 to 12 cm is to enable the vegetation seedlings to fully grow healthily in the seedling container. If the transplanting depth of the vegetation seedlings is too low, the vegetation seedlings will be overly exposed to the air, and the nutrient soil for the seedlings cannot be fully protected after subsequent planting, and the purpose of the water-retaining and maintenance-maintaining transplanting method cannot be achieved. If the transplanting depth of the vegetation seedlings is too deep, the vegetation seedlings cannot fully absorb moisture and sunlight in the air, resulting in weakened photosynthesis, which is not conducive to the healthy development of the root system.

[0069] In some specific embodiments, the above process is specifically as follows:

[0070] Fill the seedling raising nutrient soil into the seedling raising container. At this time, the filling height of the seedling raising nutrient soil and the height of the opening of the seedling raising container are 8 to 12 cm. Then place 1 to 3 plant seedlings on the surface of the seedling raising nutrient soil and in the middle of the seedling raising container to keep the root system fully stretched. Then fill the seedling raising container with the seedling raising nutrient soil and water it on the same day to ensure that it is thoroughly watered. Keep the soil moist during the subsequent seedling raising period.

[0071] As an implementation method of the present application, before transplanting the plant seedlings to the seedling raising container for raising the seedlings, the plant seedlings are pre-treated;

[0072] The pre-treatment comprises: disinfecting and sterilizing the plant seedlings, and then soaking them in rooting water for 1-5 minutes.

[0073] The present application performs the above-mentioned pre-treatment on the vegetation seedlings, which is more conducive to the growth of the vegetation seedlings in the seedling container.

[0074] As an implementation method of the present application, the specific process of planting the vegetation seedlings and the seedling raising container together in the ground includes:

[0075] Transferring the plant seedlings and the seedling raising container together into a planting pit, and then covering the planting pit with soil to fill it up;

[0076] The parameters of the planting pit include: depth ≥30 cm, diameter ≥40 cm.

[0077] The purpose of controlling the depth of the planting pit to be ≥30 cm and the diameter to be ≥40 cm in this application is to place the nursery container containing the plant seedlings at a certain depth below the ground surface to prevent the evaporation of water and nutrients, and better play the role of water conservation and maintenance. Based on the above size requirements, the specific size of the planting pit can be determined according to the size of the nursery container to ensure that the nursery container can be smoothly moved into the planting pit. Under normal circumstances, the size of the planting pit is preferably 30~45cm deep and 40~60cm in diameter.

[0078] As an implementation mode of the embodiment of the present application, before the vegetation seedlings and the seedling raising container are planted together in the field, the waterless planting method further includes: seedling hardening.

[0079] In the present application, before the vegetation seedlings and the seedling container are planted together in the field, the existing disclosed seedling hardening technology can be used to harden the vegetation seedlings. Its function is to take measures such as ventilation, cooling, and appropriate water control to force the seedlings to exercise in the case of protected seedling cultivation, so that they can quickly adapt to the adverse environmental conditions on land after planting, shorten the seedling acclimatization time, and enhance resistance to low temperature, strong wind, etc. In some specific embodiments, the specific process of hardening the seedlings includes: within one week before planting in the field, the vegetation seedlings and the seedling container are placed outdoors to keep the soil moist.

[0080] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0081] Example 1-9 provides a waterless planting method suitable for water-deficient areas. The planting experiment site is Weiqi Town, Shandan County, Zhangye City, Gansu Province. The water content of the soil in the planting site is less than 8% by mass fraction. The waterless planting method includes:

[0082] S1. Breed and raise the seeds of vegetation to be planted in a heat-insulating greenhouse, mix the nutrient medium for breeding and raising seedlings into the soil layer with a thickness of about 2 cm, maintain the temperature in the greenhouse at about 20°C, and the ambient humidity at about 45%; wherein, in terms of mass fraction, the nutrient medium includes: 25% of sterilized cow dung, 25% of sterilized pig dung, 20% of sterilized humus soil, and 30% of sterilized husk;

[0083] S2. When the plant seedlings to be planted in S1 reach a certain height A above the soil, transfer one plant seedling to the middle position of a degradable planting bag (the degradation time of the degradable planting bag is within 18 months, and it has been disinfected and soaked in rooting water for 8 minutes before entering the bag), the transplanting depth of the plant seedling is 10 cm (that is, the distance between the root of the plant seedling and the bag opening of the planting bag is 10 cm), and after evenly filling and leveling the soil, place it in a windless and rainless place in the greenhouse. Water it on the same day, and then just keep the soil moist until the plant seedlings are cultivated to a certain growth height B and the roots grow out of the planting bag to a certain root length C, and then transfer the plant seedlings and the planting bag together to the planting pit for planting, and then cover the planting pit with soil to level it;

[0084] S3. After planting in the field, the seedlings do not need to be watered or otherwise cultivated and managed.

The waterless planting method first cultivates the vegetation seedlings in a seedling container to a specific growth node, and then uses a water and soil conservation method to plant them in the ground. After planting in the ground, the vegetation seedlings do not need to be irrigated with water or other cultivation management, and the planting of vegetation such as forage grass and sand-dwelling seedlings in water-scarce areas such as deserts, deserts, and Gobi can be successfully achieved, which greatly reduces the existing ecological restoration steps in arid and desertified areas and the manpower, material resources and subsequent maintenance costs invested in the entire planting process.
