Description

Technical Field

[0001] The invention belongs to the technical field of environmental ecological protection, and specifically relates to a method for three-dimensional greening of coastal ecological protection windbreak forests using thick rattan, which strengthens the ecological functions of the windbreak forests in terms of windbreak, temperature reduction, salt blocking, and carbon sink increase. Background Art

[0002] Coastal windbreaks refer to a special type of shelterbelt located in coastal areas. Its important significance mainly includes the following aspects: Windbreak and sand fixation: Coastal windbreaks can block wind and sand, reduce wind speed, effectively fix sand dunes and beaches, and reduce the damage of wind and sand to the surrounding environment. Protect the ecological environment: Coastal windbreaks are an important part of the coastal ecosystem. They can provide habitats and food sources, maintain and protect the biodiversity of coastal areas. Maintain farmland production: Coastal windbreaks can protect farmland from strong winds, reduce wind damage to crops, and increase the yield and quality of farmland. Tourism landscape value: Coastal windbreaks have unique natural scenery and provide an important part of sightseeing and leisure services. Therefore, protecting and building high-quality coastal windbreaks is an important task of environmental protection and ecological construction.

[0003] Vertical greening refers to a means of greening urban spaces or other vertical surfaces, which used to be of great significance in urban environments. Vertical greening can increase the area of ​​urban green space, enrich urban vegetation types, provide more oxygen release and air purification functions, and thus improve the ecological environment. Vertical greening can also reduce the temperature of the surrounding environment through transpiration and shade effects, alleviate the heat island effect, and improve the comfort of the city. At the same time, vertical greening provides more habitats and food sources, attracts and supports various plants and animals, and promotes the balance and diversity of the ecosystem. This plays a positive role in protecting birds, insects and other wild animals and plants in the city. In summary, vertical greening is of great significance in the urban environment. It can not only improve the ecological environment and urban climate, but also improve the quality of human life and the sustainable development of the city.

[0004] The vertical greening of coastal windbreaks is an ecological governance method for coastal areas. It aims to green the vertical space through the planting and management of vegetation, further reduce the wind force in coastal areas, and enrich the ecological function and aesthetics of windbreaks. Traditional coastal windbreaks are usually formed by ground vegetation, while vertical greening can use vertical space to expand the greening range of coastal windbreaks to more spatial areas. At present, most of the vertical greening of coastal windbreaks has not been fully developed and applied. The vertical greening of coastal windbreaks can further enhance the ecological function of windbreaks. By planting various plants in the vertical space, the diversity of plant species can be increased, more habitats and food sources can be provided, and the protection of biodiversity can be promoted. In addition, vertical greening can also increase the green coverage area, provide more oxygen release and air purification functions, and improve environmental quality.

[0005] At present, there are four obvious shortcomings and deficiencies in the existing methods of building three-dimensional greening of coastal windbreaks: 1. Plant growth restrictions: Due to environmental erosion and damage, as well as insufficient soil, water and nutrient supply, plant growth will be restricted. How to better guide the three-dimensional growth of greening plants is the key technology to improve the benefits of three-dimensional greening. 2. Plant selection and adaptability: Due to the particularity of the coastal environment, the selection of suitable native species is very limited. The vines that have been adopted are often introduced plants from foreign countries, which are prone to risks such as biological invasion. 3. Difficult maintenance and high cost: Three-dimensional greening requires regular management and maintenance, including watering, pruning, fertilization, and pest and disease control. However, due to the limitations of vertical space, these management and maintenance tasks may be more difficult and time-consuming, requiring more manpower and resources. At the same time, compared with traditional ground greening, the three-dimensional greening of coastal windbreaks involves investment in structural design, plant selection, irrigation systems, etc., and the construction cost is relatively high. 4. It is impossible to work synergistically with shelterbelts to effectively improve the ecological and ecological functions of shelterbelts. Summary of the invention

[0006] Based on the problems existing in the background technology, the purpose of the present invention is to provide a method for three-dimensional greening of coastal ecological protection windbreak forests using thick rattan.

[0012] In the preferred embodiment, the method for three-dimensional greening of coastal ecological protection windbreak forests of the present invention, step 1) is specifically to cultivate 2 to 3 thick vine cuttings or collected seeds in each pot, and use a cultivation pot with a diameter of 20 to 30 cm and a depth of 15 to 25 cm. The soil pH is selected to be >6, and the soil organic carbon content is 0.4% to 6%. At the same time, compound fertilizer is added one month after planting, and the cultivation is carried out for one year under outdoor conditions (annual average temperature >20°C). During the cultivation process, the side branches are cut off in time, gravel or dead branches are laid under the main stem of the thick vine, and the side branches and leaves on the main stem are removed one week before transplanting, leaving only the buds at the top.

[0013] Preferably, the seedling raising process uses a cultivation pot with a diameter of 25 cm and a depth of 20 cm.

[0014] Preferably, the seedling raising process uses a diameter of 25 cm and a soil organic carbon content of 0.52%.

[0015] Preferably, during the seedling raising process, compound fertilizer (N:P2O5:K2O=25:12:8) is added one month after planting.

[0016] Preferably, the seedlings are grown to a base diameter > 8 mm and a main stem creeping length > 2 m.

[0017] In the preferred embodiment, the method for three-dimensional greening of coastal ecological protection windbreak forests of the present invention, step 2) is specifically as follows:

[0018] Identify trees suitable for construction in coastal windbreaks or scenic forests as the working space for three-dimensional greening under the forest, clear the side branches on the tree trunks that hinder light and plant growth, build 3 to 4 support frames for the trees. The support frames are made of tubular materials, and the top of the support frames is fixed on the main trunk of the tree 0.5 to 1.5 m above the ground. A hole is opened every 5 to 25 cm above the tube, and soft materials are filled between the connecting parts and the trunks of the trees. Half of the 15 to 25 cm part of the bottom of the support frame steel pipe is cut longitudinally and removed for the laying of thick vines. After the thick vines are transplanted, they are buried in the soil 15 to 18 cm with the inside facing down.

[0019] Preferably, coconut trees, Casuarina equisetifolia, Acacia macrophylla and Terminalia tatarinowii are selected as the working space for three-dimensional greening under the forest, with newly planted trees being given priority.

[0020] Preferably, the support frame is a steel pipe, preferably a rust-proofed steel pipe, and a further preferred material is a plastic-sprayed galvanized steel pipe.

[0021] Preferably, the top end of the steel pipe of the support frame is fixed to the trunk of the tree at a distance of 1 to 1.5 m from the ground by screws and metal connectors.

[0022] Preferably, a hole with a diameter of 5 mm is opened every 20 cm on the top of the tube.

[0023] Preferably, soft materials such as palm trees are filled between the connecting member and the tree trunk.

[0024] Preferably, half of the bottom 20 cm portion of the support frame steel pipe is longitudinally cut and removed.

[0025] In the preferred embodiment, the method step 3 of three-dimensional greening of coastal ecological protection windbreak forest of the present invention is specifically to dig a cultivation pit on the ground where each support frame base is located, put the cultivated thick vine from the culture pot into the cultivation pit with roots and seedlings, and let the main stem of the thick vine pass through the support frame steel pipe from bottom to top, so that the base of the main stem of the thick vine is placed on the inner side of the support frame steel pipe, and fill the gap with guest soil until the support pipe steel frame is fixed, and bury the part of the thick vine exposed at the base of the pipe with soil to facilitate the later weeding management. The four legs of the support frame can be constructed in sequence according to the specific situation. Due to the high survival rate, usually 2-3 pots can be transplanted and laid, and 1 pot can also be transplanted and laid under the condition of good soil moisture conditions.

[0026] Preferably, the size of the cultivation pit is 30×30×30 cm.

[0027] Preferably, only two thick vines are retained in each pot, and the main stem with the best growth is retained.

[0028] In the preferred embodiment, the method of three-dimensional greening of coastal ecological protection windbreak forest of the present invention, step 4) is specifically to mix the soil for planting thick vines with dry coconut husk to form a filling matrix, fill the matrix into the steel pipe where the main stem of the thick vine is laid, and then water it thoroughly in small amounts and multiple times, and prune the main stem of the thick vine that is longer than the steel pipe. In addition, 2-3 circles of gardening wire can be fixed 30cm below the top of each support frame root steel pipe to support the unfolded thick vine, so that it can give full play to the effect of three-dimensional greening. After one month of planting in the plant growth season, the initial effect can be seen, and a small amount of conventional management can be supplemented at the same time.

[0029] Preferably, the soil is mixed with dry coconut husk in a weight ratio of 1:8, and 0.5% of slow-release fertilizer is added.

[0030] Preferably, the substrate is kept dry before filling, and 300 to 500 g of dry substrate is filled from the upper end into the steel pipe where the thick vine main stem is laid.

[0031] Preferably, the thick vine main stems that are longer than the steel pipes are pruned, and each main stem that is exposed at the top retains 3 to 4 internodes (about 20 cm).

[0032] Preferably, the number of watering times is based on thorough watering.

[0033] On the other hand, the present invention provides the use of thick rattan in strengthening the ecological functions of coastal ecological protection windbreaks such as windbreak, temperature reduction, salt resistance, and increased carbon sink, and the application is implemented according to the above-mentioned method.

[0034] On the other hand, the present invention provides a method for screening green plants that enhance the ecological functions of windbreak, temperature reduction, salt blocking, and carbon sink enhancement in coastal ecological protection windbreaks, characterized in that it comprises the following steps:

[0035] 1) Plant the cuttings of the selected species in pots.

[0036] 2) After being stable for one month, place it at a height of more than 20 cm above the ground and expose it to sea breeze and salt spray.

[0037] 3) Select plants with the highest survival rate as candidate greening plants.

[0039] 0.52%, and regularly add slow-release compound fertilizer (N:P2O5:K2O=25:12:8).

[0040] In the preferred embodiment, the plants are planted in a flower pot with a diameter of 15 cm and a height of 20 cm.

[0041] In the preferred solution, after being stabilized for one month, the sample is fixedly placed 100 cm above the ground and exposed to sea breeze and salt spray for 6 weeks.

[0042] In the preferred embodiment, water is applied thoroughly before the start of the test and no water is applied during the test.

[0043] In a preferred embodiment, plants with a survival rate higher than 90% and a biomass growth higher than 100% are selected as candidate greening plants, and the preferred survival rate is 96%.

[0044] Compared with the prior art, the present invention has the following advantages:

[0045] 1) The present invention uses the method of adding a support, and does not need to fill the soil in the vertical direction, which solves the trade-off problem of water utilization of three-dimensional greening plants. During the implementation process, the top dominance of the main root and main stem of the thick vine is maintained, and the side branches and roots are prevented from growing wildly. It also takes into account water conservation and plant growth, and improves the survival rate and biomass;

[0046] 2) Utilize the biological characteristics of thick vines and salt-resistant plants to achieve adaptability to salt spray, strong winds, drought, etc., and strengthen the ecological functions of windbreaks in terms of windbreak, temperature reduction, salt blocking, and carbon sink enhancement;

[0047] 3) As a native species, thick rattan not only has stable effects, beautiful appearance and few pests, but also can avoid the potential risk of invasion of alien species;

[0048] 4) Comprehensive utilization of native species and tree support schemes as well as simple post-management have the advantages of high feasibility, low construction and maintenance costs, and large-scale promotion and use to enhance the protective function of coastal defense forests, while also having certain ecological, economic and social benefits.

DETAILED DESCRIPTION

[0054] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0056] Example 1: Method for three-dimensional greening of coastal windbreak forests - Taking Hainan coral islands and reefs as an example

[0057] Step 1. Species selection and cultivation

[0058] By consulting literature, common stem-node rooting greening plants in the coastal areas of Guangdong and Hainan, such as red-leafed syngonium, colorful-leafed sweet potato, ficus pumila, sea bean, and simple-leafed vitex, were used as comparisons with thick vines to conduct cultivation screening tests in coastal windbreak areas. From September to October (average temperature above 25°C), 30 cm long cuttings of the selected species were planted in pots with a diameter of 15 cm and a height of 20 cm. It is usually a mixture of coral sand and guest soil, with a pH>6 and a soil organic carbon content of 0.52%. At the same time, a slow-release compound fertilizer (N:P2O5:K2O=25:12:8) is added one month after planting. After one month of stable planting, it is fixedly placed 100 cm above the ground ( Figure 1 ), exposed to sea breeze and salt spray for 6 weeks, watered thoroughly before the start of the experiment, and no watering during the experiment. The results showed that among the four candidate species, Thick Teng had the highest survival rate (96%) and the highest biomass growth (298%) (see Table 1).

[0059] Table 1

[0060]

[0061] Thick vines used for constructing three-dimensional greening were selected as planting materials. The planting method is cutting, with thick vine long branches as the main ones (seeds can also be collected to cultivate seedlings), and the survival rate can usually reach more than 70%. Therefore, cultivating 2 to 3 thick vines in each pot can ensure a seedling rate of >90%. During the cultivation process, a cultivation pot with a diameter of 25 cm and a depth of 20 cm is used. The soil pH is selected to be >6, and the soil organic carbon content is 0.52%. At the same time, compound fertilizer (N:P2O5:K2O=25:12:8) is added regularly. After one year of cultivation under outdoor natural conditions (optimal average temperature above 25 degrees Celsius), the base diameter is >8mm and the main stem creeping length is >2m. During the cultivation process, the side branches are cut off in time to retain the top growth advantage of the main stem. Stone dead branches are laid under the main stem of the thick vine. On a sunny day one week before transplanting, the side branches and leaves on the main stem are removed, leaving only the top buds.

[0062] Step 2. Build the tree support

[0063] Determine the trees suitable for construction in the coastal windbreak forest or landscape forest (usually coconut trees, Casuarina, Acacia macrophylla and Terminalia macrophylla, etc.) as the working space for the three-dimensional greening under the forest, and newly planted trees are preferred. Clear the side branches on the tree trunks that hinder light and plant growth, and build a tree support frame. The material of the support frame is spray-coated galvanized steel pipe, or other types of steel pipes with surface anti-rust treatment to increase the aesthetics and extend the service life. The top of the support frame steel pipe (usually 3 to 4 pieces) is fixed to the main trunk of the tree 1 to 1.5m from the ground with screws and metal connectors. A 5mm diameter hole is opened every 20 cm above the pipe for drainage and ventilation. Soft materials such as palm are filled between the connector and the tree trunk. Half of the 20cm part of the bottom of the support frame steel pipe is cut longitudinally and removed for the laying of thick rattan. After the thick rattan is transplanted, it is buried in the soil with the inner side facing down for 15 to 18cm. The schematic diagram of the present invention using a tree support frame to plant thick rattan to achieve the three-dimensional greening effect of the windbreak is as shown in the following figure Figure 4 shown.

[0064] Step 3. Transplanting and laying of thick vines

[0065] Dig a 30×30×30cm cultivation pit on the ground where each foot of the support frame steel pipe is located, and put the cultivated thick vine from the culture pot into the cultivation pit with roots and seedlings. Only 2 thick vines are kept in each pot, and the main stem with the best growth is kept. The main stem of the thick vine is passed through the support frame steel pipe from bottom to top, and the base of the thick vine main stem is placed on the inner side of the support frame steel pipe. Fill the gap with fertile guest soil until the support pipe steel frame is fixed, and bury the part of the thick vine exposed at the base of the pipe with soil to facilitate the later weeding management. The four legs of the support frame can be constructed in sequence according to the specific situation. Due to the high survival rate, usually 2 to 3 pots are enough for transplanting and laying. Under the condition of good soil moisture conditions, 1 pot can also be transplanted and laid.

[0066] Step 4. Matrix loading and management

[0067] The soil for planting thick vines (usually a mixture of coral sand and foreign soil, pH>6, organic carbon content>0.52%, plus slow-release compound fertilizer (N:P2O5:K2O=25:12:8)) is mixed with dry coconut bran in the optimal ratio of 1:8 by weight, and 0.5% slow-release fertilizer is added to form a filling matrix. This matrix uses the good water retention, air permeability and slow decomposition of coconut bran to provide lateral roots and resources for the thick vines passing through the steel pipe of the support frame. 300-500g of dry matrix is ​​filled into the steel pipe where the main stem of the thick vine is laid from the top, and then water is poured from the top in small amounts and multiple times to make the coconut bran matrix in the tube fully foamed and fluffy. The main stem of the thick vine that is longer than the steel pipe is pruned, and each main stem exposed at the top retains 3-4 internodes for sprouting new branches (about 20cm). In addition, 2 to 3 circles of gardening wire can be fixed 30 cm below the top of the 4 steel pipes of the support frame to support the thick vines after they are spread out, so that they can fully exert the effect of three-dimensional greening. The initial effect can be seen one month after the plant is planted during the growing season, and a small amount of routine management can be supplemented at the same time.

[0068] Example 2 Optimization of tree support frame

[0069] To determine the appropriate height of the tree support frame and the density of drainage holes, the top of the support frame steel pipe (usually 3-4 pieces) is fixed with screws and metal connectors to the tree trunk at 0.5, 1.0, 1.5, 2.0, and 2.5m from the ground. Cross-control experiments are carried out every 5, 10, 15, 20, and 25cm above the pipe.

[0070] One month after planting, the results showed that the top of the support frame steel pipe was fixed with screws and metal connectors to the tree trunk 0.5 to 1.5 meters above the ground, and the survival rate was as high as >60%, and as high as more than 80% ( Figure 2 ), the hole density has an impact on the survival rate and plant growth. The plant survival rate and growth are best when a 5 mm diameter hole is opened every 20 cm above the tube ( Figure 2 , Table 2).

[0071] Table 2 Growth of top plant biomass at different heights and opening densities

[0072]

[0073] Example 3 Optimization of cultivation substrate

[0074] The soil for planting thick vine (usually a mixture of coral sand and imported soil, pH>6, organic carbon content>0.52%) was mixed with dry coconut bran at a weight ratio of 1:8, and 0.5% slow-release fertilizer (N:P2O5:K2O=25:12:8) was added to form a filling matrix. By comparison, this matrix has a significant promoting effect on the survival and growth of thick vine under the support tube condition (Table 3 and Figure 3).
