Description

Technical Field

[0001] The invention belongs to the technical field of forestry, and in particular relates to an "ecological afforestation" method that integrates harvesting and cultivation. Background Art

[0002] In current forestry production, felling and afforestation are usually carried out separately. The felling is carried out by the engineering team using the corresponding equipment, and the afforestation is carried out by the forestry engineering team. Generally, felling projects need more than half a year or a year to complete felling, timber making and sales before they can be handed over to the next process for bidding for afforestation.

[0003] In addition, the traditional farming techniques of forestry only consider the growth of trees, lack of biodiversity protection and original ecological maintenance, leading to forest degradation and difficulty in sustainable management. For example, in terms of afforestation and land preparation, the traditional forestry method is generally to "refine" the mountain or to cultivate the land according to the same height specifications, causing serious soil erosion; in terms of afforestation density, it is generally based on site conditions and local conditions, with plant spacing of 2m×1m, 2m×1.5m, 2m×3m, etc., and the number of plants per mu is 111-333 / mu, without standard afforestation; in terms of young forest tending, block tending is usually adopted, that is, loosening the soil, weeding and cultivating within a radius of 50-60cm around the young tree, or strip tending is adopted to loosen the soil and weed locally on both sides of the young fir to form a strip of weeding with a width of 80-100cm and the same height, and the surrounding grass, shrubs and vines that hinder the growth of the young forest are cut off, and ecological protection is not considered during the period.

[0004] It can be seen that in the traditional logging and afforestation process, the forest land will be wasted for more than half a year or a year without cultivation. During the afforestation management, there is also a lack of forest biodiversity protection measures and forest land breeding and development. As a result, the forest land continues to degrade and is not sustainable. Therefore, a new "ecological afforestation" method that takes into account both forestry production and ecological protection is urgently needed, and by adjusting the production method, time waste can be avoided and the efficiency of forest land utilization can be improved. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an "ecological afforestation" method that integrates logging and afforestation. Through the design of timber sliding hills and 1 / 3 "afforestation belts" and 2 / 3 "ecological belts" forest land, ecological priority afforestation is implemented, and logging and afforestation are carried out simultaneously, so that the forest land can be managed efficiently and sustainably.

[0006] In order to achieve the above-mentioned object of the invention, the present invention provides the following technical solutions:

[0007] An "ecological afforestation" method integrating felling and cultivation, comprising the following steps: felling and killing of stumps → ecological weed control → timbering and hill-ditching → forest land design → deep plowing and mound making → forest belt afforestation → forest belt weed control → mound protection and fertilization → ecological maintenance → thinning and timbering and hill-ditching;

[0008] The timber rolling includes: felled trees are rolled into timber in accordance with market demand specifications in the forest land, rolled down the slope to the timber collection point, and stacked for sale;

[0009] The forest land design includes: dividing the forest land into vertical "afforestation belts" and "ecological belts" distributed at intervals along the vertical direction of the mountain contour lines; the width of the "afforestation belt" is 0.8-1.2m, where trees are planted; the width of the "ecological belt" is more than 1.8m, where the original forest land ecological environment is preserved;

[0010] The deep plowing and mound making includes: deep plowing and land preparation of the "afforestation belt" to construct an "afforestation mound" 18-25cm higher than the "ecological belt";

[0011] The afforestation in the "afforestation belt" includes: planting tree seedlings in the center of the "afforestation pile".

[0012] Preferably, the forest land is cleared before felling and stump removal, including: cutting weeds, shrubs and vines in the forest before felling.

[0013] Preferably, the felling and stump killing comprises: after felling, spraying a stump killing agent on the felled stump surface, wherein the "stump killing agent" is selected from one or more of the sulfonylurea herbicides.

[0014] Preferably, the ecological weed control comprises: spraying a selective herbicide "grass-killing agent" on the entire forest, wherein the selective herbicide "grass-killing agent" is selected from one or more aromatic oxygen phenoxy propionic acid herbicides.

[0015] Preferably, during the deep tillage, the soil is plowed to a depth of 50-80 cm and an inner ditch is set in the "afforestation mound".

[0016] Preferably, the weed control in the forest belt comprises: applying "weed sealant" to the afforestation belt 20-40 days after the trees are planted, wherein the "weed sealant" is selected from Gol or Simazine.

[0017] Preferably, the mound protection and fertilization includes: in early April of the following year after the trees are planted, the "afforestation mound" is protected by soil, and fertilizers are applied in holes next to the trees.

[0019] Preferably, it also includes forest farming after weed control in the forest belt, planting grains, oils, fruits and vegetables between the trees in the "afforestation belt", and / or planting one or more of mushroom grass, Chinese herbal medicine and edible fungi in the "ecological belt".

[0020] Preferably, during the felling and stump removal and thinning, the discarded branch residues are used to cover the forest land.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The innovative concept of "ecological afforestation". The "ecological afforestation" method of the present invention combines harvesting and cultivation, and first gives priority to ecology in the afforestation process. The forest land is divided into "ecological belt" and "afforestation belt" during the afforestation process. The "ecological belt" does not require hoeing or earthwork, and is absolutely protected. It occupies about 2 / 3 of the forest area, thus protecting the original ecological environment of the forest land and the biodiversity of the forest land. It is an innovative concept first proposed and practiced in artificial afforestation.

[0023] (2) "Afforestation belt" protects the ecology. It is generally believed that vertical afforestation is not conducive to soil and water conservation. Most traditional afforestation methods adopt horizontal belt planting with equal height. The present invention changes the round afforestation mound into a horizontal long mound, which prevents soil and water loss. Deep plowing is beneficial to the growth of young trees and helps to reduce damage to the remaining trees during thinning. That is, "afforestation belt" afforestation and "ecological belt" protect the forest ecology.

[0024] (3) Promote rapid growth and high yield of trees. Deep plowing and mounding ensure that trees grow in loose soil; in their early years, under the care of the "ecological belt", trees receive sufficient sunlight and late dew, which meets the biological characteristics of trees and helps them grow healthily.

[0025] (4) "Forestation and afforestation" grain and oil go up the mountain. The present invention can plant grain, oil, fruits and vegetables between two young trees in the "afforestation belt", or plant mushroom grass, Chinese herbal medicine and edible fungi in the "ecological belt". Under the guidance of the big food concept, vigorously develop the forest economy.

[0026] (5) Ecological restoration of degraded forest land. The present invention provides the best technical method for the transformation and restoration of degraded forest land. The present invention can restore the original ecology of forest land, protect biodiversity, and achieve sustainable management. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The present invention provides an "ecological afforestation" method that integrates felling and cultivation, comprising the following steps: felling and destroying stumps → ecological weed control → timber making and hill sliding → forest land design → deep plowing and mound making → forest belt afforestation → forest belt weed control → mound protection and fertilization → ecological maintenance → thinning and timber making and hill sliding; preferably, it is further combined with forest cultivation to improve the ecological benefit, comprising the following steps: felling and destroying stumps → ecological weed control → timber making and hill sliding → forest land design → deep plowing and mound making → forest belt afforestation → forest belt weed control → forest land cultivation → mound protection and fertilization → ecological maintenance → thinning and timber making and hill sliding.

[0031] In the present invention, it is preferred to perform felling and stump removal for forest land clearing, including: cutting weeds, shrubs, and vines in the forest before felling. As an implementation method, a brush cutter is used for cutting. Forest land clearing can ensure felling safety and facilitate timber production.

[0032] In the present invention, felling and stump killing includes: after felling, spraying a stump killing agent on the felled stump surface, wherein the "stump killing agent" is selected from one or more of the sulfonylurea herbicides, and preferably the "stump killing agent" is a combination of sulfosulfuron-methyl and an organophosphorus herbicide, and more preferably a combination of sulfosulfuron-methyl and glyphosate. The present invention does not specifically limit the application amount of the "stump killing agent", and it can be applied according to the recommended amount of the relevant product. As a feasible implementation method, when felling artificial forests, the fellers carry the "stump killing agent" and spray the stump surface with the "stump killing agent" immediately after felling. Fresh felled stumps absorb the "stump killing agent" and then conduct it to the roots of the trees, inhibiting the division of root cells and dying, so that new plants cannot sprout; in addition, after the expanded roots wither and rot, they provide a large amount of organic matter and porosity for the forest soil, promote the growth of planted trees, and avoid the forest sprout removal operation.

[0033] In the present invention, ecological weed control includes: spraying the whole forest with a selective herbicide "Mite", wherein the selective herbicide "Mite" is selected from one or more aromatic oxyphenoxypropionic acid herbicides, preferably a combination of haloxyfop-butyl and clethodim, and further preferably a selective herbicide "Mite", and using a drone for ultra-low volume spraying. The present invention does not specifically limit the application amount of the selective herbicide "Mite", and it can be applied according to the recommended amount of the relevant product. After felling and killing the piles, plants such as Miscanthus fragrans, Imperata cylindrica, and bamboo shoots in the forest grow again. The selective herbicide "Mite" is used for prevention and control, which can effectively protect the biodiversity of the forest while killing weeds.

[0034] In the present invention, the timber rolling includes: felled trees are cut into timber in accordance with market demand specifications in the forest land, rolled down the slope to the timber collection point, and stacked for sale. This method avoids the problem that the general felling project needs more than half a year or a year to complete felling, timbering, sales, and then forestation, thus reducing time waste and improving forest production efficiency.

[0035] In the present invention, the forest land design includes: along the vertical direction of the mountain contour line, the forest land is divided into vertical "afforestation belts" and "ecological belts" distributed at intervals, the "afforestation belt" is 0.8-1.2m wide, and trees are planted, and the "ecological belt" is more than 1.8m wide to retain the original forest ecological environment; when the planted trees are preferably fir, the "afforestation belt" is 1m wide and the "ecological belt" is more than 2m wide; when the planted trees are nanmu, the "afforestation belt" is 1m wide and the "ecological belt" is more than 3m wide. As an implementable embodiment, the present invention constructs a vertical "afforestation belt" and a vertical "ecological belt" in the following manner: at the left and right centers of each slope of the forest land, pull a plastic colored rope (pencil thick) to lay a vertical line from the top of the mountain to the bottom of the mountain as a "center rope"; three people take a pencil-thick plastic "row spacing rope" (such as a fir row spacing rope with a marking knot every 3 meters) and straighten it horizontally at 90° from an appropriate position on the mountain to intersect with the "center rope". One person grabs the intersection at the "center rope" position, and the other two people straighten it horizontally in the left and right directions and walk to the end. When walking, the central person directs the two people on the left and right to straighten, tighten and fix it. Then the three people insert a "marking stick" at each 3-meter node (the "marking stick" is 1.5 meters long, one end is pointed and inserted into the ground, and the other end is tied with red plastic cloth for marking). It must be inserted straight and not tilted. The same method is used to insert marks in the mountain and at the bottom of the mountain for marking when the excavator is working, completing the design and positioning of the "afforestation belt" and "ecological belt". The present invention adheres to the principle of ecological priority. In the process of afforestation, 2 / 3 or more of the forest land constructs an "ecological belt" to protect the original ecology and biodiversity of the forest land, and about 1 / 3 of the forest land constructs an "afforestation belt" for afforestation. The "afforestation belt" and the "ecological belt" promote and restrict each other, and their advantages complement each other. The tree seedlings can get shade and cooling from the ecological belt during the period of afforestation, so as to achieve afforestation while taking into account the efficient and sustainable management of the forest land.

[0036] In the present invention, deep plowing and pier making include: deep plowing of the afforestation belt, land preparation to construct an "afforestation pier" 18-25cm higher than the "ecological belt", preferably the "afforestation pier" is 20cm higher than the "ecological belt". Preferably, the deep plowing is 50-80cm, and more preferably 60cm. Preferably, an inner ditch is set in the "afforestation pier", the inner ditch is perpendicular to the "afforestation belt" and leads to the "ecological belts" on both sides, and more preferably the inner ditch is 30cm deep, the inner ditch can hold water when it rains, and can block water during heavy rain, and the excess rainwater flows to the "ecological belt", and will not form surface runoff of the "afforestation belt" to cause soil and water loss. As an implementable method, the deep plowing and pier making of the present invention adopts the following method: according to the mark of the forest land design, the excavator aligns the upper and lower vertical marks to perform deep plowing to form a "forestation belt"; under the guidance of the vertical mark, the excavator walks from the bottom of the mountain to the top of the mountain for about 3m, puts down the plug plate to fix the excavator, twists the digging head and inserts it into the soil at the bottom of the mountain, retracts the hook head, and raises the soil full of the hook head to a certain height (above the ground) and throws it back to the original position, turning the original bottom soil to the table surface, and turning the table surface soil and weeds and grass seeds into the bottom and burying them deeply, After continuously turning the soil for 4-6 times, when the table surface reaches about 2m, the plane of the afforestation belt is leveled; the same operation is continued to the top of the mountain, and deep turning is carried out from the top of the mountain to the bottom of the mountain, and one slope is completed before another slope is completed; when the excavator is deep turning, "afforestation piers" are made at the same time. Different trees have different upper and lower pier distances. For example, when the excavator is deep turning the belt of fir, the hook is inserted into the soil 40cm at a distance of 1m, and the full hook of soil is dug up and thrown downwards, forming a horizontally long "afforestation pier" 18-25cm higher than the "ecological belt".

[0037] In the present invention, forest belt afforestation includes: planting tree seedlings in the center of the "afforestation mound", with different trees having different mound spacings. As an optional implementation, the preferred mound spacing for Chinese fir is 1m, and the mound spacing for nanmu is 2m. Further preferred trees are selected from good quality and strong seedlings, and the trees are planted not against the mountain, with the upper and lower seedlings aligned in a vertical line.

[0038] In the present invention, weed control in the forest belt includes: 20-40 days after the planting of trees, preferably 30 days later, the afforestation belt is applied with a "shrub sealant", the "shrub sealant" is selected from Gol or Simazine, and the application method is further preferably broadcasting or spraying, and avoiding the tree seedlings. The present invention does not specifically limit the application amount of Gol or Simazine, and can be applied according to the recommended dosage of the relevant products. Gol or Simazine can prevent the growth of shrubs (Litsea cubeba, Litsea cubeba, Saltwort, etc.) and weeds (mainly perennial weeds such as Gramineae and Cyperaceae) in the "afforestation belt", so that the above-mentioned shrubs and weeds are promptly controlled and removed when they emerge from the soil, ensuring the normal growth of young trees, and also enabling the trees planted that year to achieve no-tillage.

[0039] In the present invention, it is preferred to carry out forest farming after the grass control in the forest belt is completed, and it is further preferred to include: planting grains, oils, fruits and vegetables between the trees in the "afforestation belt", and / or planting one or more of mushroom grass, Chinese herbal medicine and edible fungi in the "ecological belt". As an implementable method, grains, oils, fruits and vegetables are selected from sorghum, corn, sunflower, pumpkin, watermelon, soybean, etc., to realize the "big food concept, grains and oils go up the mountain"; mushroom grass is selected from giant mushroom grass, royal bamboo grass, etc., which are rich in protein and are used to cultivate edible fungi, and can also be used to raise poultry such as chickens, ducks, and geese at the same time. The present invention does not specifically limit the specific field management of forest farming, and the common forest farming methods in the field can be adopted.

[0040] In the present invention, the mound protection and fertilization includes: in early April of the following year after the planting of trees, the "afforestation mound" is protected by soil, and fertilizers are applied in holes beside the trees; preferably, fertilizer holes are dug 20 cm away from the tree seedlings, and the fertilizer holes are 10 cm deep, 15 cm wide, and 25 cm long, high-nitrogen quick-acting compound fertilizer is spread, and the soil is covered.

[0041] In the present invention, ecological maintenance includes: during the forest cultivation period, when the plants in the "ecological belt" invade the "afforestation belt", the invading plants are cut off and controlled to prevent the invasive plants from affecting the growth of the forest.

[0042] In the present invention, thinning by alternating trees includes: thinning by alternating trees 6-8 years after the trees are planted, preferably thinning by alternating trees 7 years after the trees are planted, and thinning by alternating trees is used to cultivate timber again.

[0043] In the present invention, it is preferred that the discarded branch residues during felling and stump removal and thinning are used to cover the forest land. In the afforestation process, about 8,000 kg / mu of branch residues are felled before afforestation, and about 4,000 kg / mu of branch residues are thinned. A total of about 12,000 kg / mu of branch residues are used to cover the forest land in two times, which are converted into organic fertilizers at 83% to a total of 9,960 kg / mu, effectively promoting the sustainable management of forest land.

[0044] The technical solutions provided by the present invention are described in detail below in conjunction with the embodiments, but they should not be construed as limiting the protection scope of the present invention.

[0045] Example 1

[0046] An "ecological afforestation" method that integrates harvesting and cultivation, with the following specific steps:

[0047] (1) Forest clearing: Before felling, use a brush cutter to remove weeds, shrubs and vines in the forest to ensure felling safety.

[0048] (2) Felling and stump elimination: The artificial forest is clear-cut. When felling, the fellers carry a "stump elimination agent" and immediately spray the stump surface with a diluted solution of the "stump elimination agent", which is a mixture of sulfamethoxam and glyphosate. The remaining branches of the felled trees cover the forest land.

[0049] (3) Ecological weed control: After felling and killing the stumps, the Miscanthus fragrans and bamboos in the forest will grow again. In order to protect biodiversity, the selective herbicide "Miscanthus fragrans" is used for elimination. Drones are used for ultra-low volume spraying to control the roots of Miscanthus fragrans, Imperata cylindrica, bamboos and other weeds. The selective herbicide "Miscanthus fragrans" is a mixture of cypermethrin and sethoxydim.

[0050] (4) Timber rolling: felled trees are rolled down the hill into timber according to market specifications, and then piled up for sale.

[0051] (5) Design of forest belts: At the center of each slope of the forest, pull a plastic colored rope (pencil thick) from the top of the mountain to the bottom of the mountain to form a vertical line as the "center rope"; three people take a pencil-thick plastic "row rope" (such as a fir row rope with a marking knot every 3 meters) and pull it horizontally from an appropriate position on the mountain to intersect with the "center rope" at 90 degrees. One person holds the intersection point at the "center rope" position, and the other two people pull it horizontally to the left and right directions and walk to the end. While walking, the center person directs the two people on the left and right to straighten and tighten it. The three people insert a "marker stick" at each 3m node (the "marker stick" is 1.5m long, one end is pointed and inserted into the ground, and the other end is tied with red plastic cloth as a mark). The stick must be straight and not tilted. The same method is used to insert marks in the mountain and at the bottom of the mountain for the excavator to mark when operating, completing the design and positioning of the vertical "afforestation belt" and vertical "ecological belt".

[0052] (6) Deep plowing and making piers: According to the design, different trees are planted at different spacings. For example, the spacing of Chinese fir is 1m (spacing on the upper and lower slopes), and the row spacing is 3m wide. The excavator aligns the upper and lower vertical marks to deep plow, forming a "forestation belt" that is 60cm deep and 1m wide. Guided by the vertical marks, the excavator walks about 3m from the bottom of the mountain to the top of the mountain, puts down the plug plate to fix the excavator, twists the digging head and inserts it into the soil at the bottom of the mountain, retracts the hook head, and raises the soil full of the hook head to a certain height (above the ground) and throws it back to its original position, turning the original bottom soil to the table surface, and the table surface soil and weeds and grass seeds are turned into the bottom and buried deeply. After turning the soil 4-6 times in a row, when the table surface reaches about 2m, the "forestation belt" plane is leveled. The same operation is continued to the top of the mountain. Deep plowing is carried out from the top of the mountain to the bottom of the mountain. After finishing one slope, do another slope. When the excavator is deep plowing, "forestation piers" are made at the same time. When the excavator is deep-digging the belt, the hook of the fir tree is inserted into the soil 40cm at a distance of 1m, and the full hook of soil is dug up and thrown down to form a horizontal long "afforestation pile". The "afforestation pile" should be 20cm higher than the ground of the "ecological belt". There is an inner ditch inside the pile, which is 30cm deep. It can hold water when it rains and block water when it rains heavily. The excess rainwater flows to the "ecological belt" and will not form surface runoff and cause soil erosion.

[0053] (7) Forest belt afforestation: In March, deep digging is done at the center of the afforestation mound to plant strong seedlings of improved varieties of trees. The seedlings are planted in a straight line.

[0054] (8) Weed control in forest belts: One month after afforestation and before planting and breeding in the forest land, spread or spray "weed blockers" on the "afforestation belts", selected from Gol or Simazine. When spraying "weed blockers", try to avoid young trees.

[0055] (9) Forest farming: Grain, oil, melon and vegetable (such as sorghum, corn, sunflower, pumpkin, watermelon, soybean, etc.) can be planted between two trees in the "afforestation belt". Or, on the vertical center line of the "ecological belt", mushroom grass (high-nutrition forage grass containing protein) can be planted to feed chickens, ducks, geese, etc. for forest farming, or Chinese herbal medicines and edible fungi can be planted.

[0056] (10) Fertilization at the mound: In early April of the second year of afforestation, the “afforestation mound” is protected by soil (pruning the afforestation mound), and fertilizer holes 10 cm deep, 15 cm wide, and 25 cm long are dug on the left and right sides of the young trees, 20 cm away from the trees. Quick-acting fertilizers (such as high-nitrogen compound fertilizers) are spread and covered with soil.

[0057] (11) Ecological protection: One to two years after afforestation, when plants in the “ecological belt” extend into the “afforestation belt” and hinder the growth of young trees, they should be cut.

[0058] (12) Thinning: Thinning is carried out 7 years after afforestation, and the remaining branches from the thinning cover the forest land.

[0059] (13) Timber rolling: The thinned fallen trees are rolled down the slope to the timber collection point and piled up for sale.

[0060] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
