According to the conditions of climate, humidity and the like in spring or rainy season, the method combines the manual direct elimination and the sealing of the root and stem rotting modes of miscanthus, and scientifically plants the wood species for use or economic tree species and other purposes in time sharing, batch and classification when the miscanthus occupies the forest land originally, thereby forming the alien multi-layer mixed forest stand.
The different-age multi-layer mixed forest stand has the characteristics of different tree species, diameters, heights and ages distributed in a harmonious symbiotic mode, and is a result influenced by various factors such as tree species growth habit, environmental conditions, operation activities and the like.
The alien multi-layer mixed forest stand obtained by the method has more advantages than simple forest due to more reasonable structure of the forest stand, and utilizes the overground, underground and time differences of different tree species distribution layers to better utilize multi-layer nutrition space and more effectively improve the condition of the site. Moreover, the cleared miscanthus sinensis is treated on site, and the miscanthus sinensis has rich biological diversity, complex withered matter components and the like, so that the miscanthus sinensis has stronger soil improvement effect and is an excellent stand.
By the technical scheme, the multi-layer heterogeneous-age mixed excellent forest stand can obtain a stereoscopic natural forest land with stronger light energy utilization, and the total biological yield of the forest stand can be improved. Because the nutrition utilization of the mixed forest is more sufficient, the soil improvement capability is stronger, the stress resistance of the forest stand is strong, the growth of the forest or economic tree species in the mixed forest is more excellent, and the growth vigor is more vigorous. The total accumulation is thus also higher and the wood quality is better. Because the different-age multi-layer mixed forest stand has more reasonable structure, the different-age multi-layer mixed forest stand has stronger capabilities of water and soil conservation, water conservation, wind prevention, sand fixation, air purification and the like, has more abundant biodiversity, better environmental beautifying effect and can fully exert various benefits of the forest stand.
Furthermore, the method artificially designs a high-density heterogeneous multi-layer hybrid forest, and the canopy density is high after forestation, so that the regeneration of miscanthus can be inhibited immediately. Because of the rich biodiversity, various natural enemies and excellent forest stand environment, along with the elimination process of the miscanthus, the capability of resisting fire, disease and insect pests, bad weather factors and the like is stronger.
According to the technical scheme, the method comprises the steps of manually and directly eliminating miscanthus sinensis, sealing, wrapping and removing the miscanthus sinensis by using degradable non-woven fabrics, distributing the quantity of planted tree seeds to natural good arbor and shrubs, preferably reserving the natural good arbor and shrubs, selecting the tree seeds from a miscanthus sinensis elimination zone, supplementing the harmless treatment means to the miscanthus sinensis, selecting the method from a modern planting method to season adaptability, degrading the non-woven fabrics by using black fabrics, preferably to a method of stuffy roots and rotten stems, and the like, so that labor resources are reasonably applied, and the miscanthus sinensis in a forest land is thoroughly eliminated within a long period of time (2-3 years and more), so that the alien multi-layer mixed forest stand meeting natural ecology is gradually obtained, and innovative technical service is provided for future forest land management and forest land income.
The scheme starts with the environment-friendly natural decomposition of the miscanthus, and in spring or rainy season, the germination and growth of new branches of the miscanthus are in a vigorous period, and the miscanthus with the heads cut off by the table is in a degradable non-woven fabric sealing state, and is in failure from the root part due to lack of assimilation substances, namely root-stuffiness symptoms appear; at the same time, the leaves that lose photosynthesis become fragile and wilt rapidly, and get stuck crowded on the stems and begin to decay. Because the water is sprayed to the miscanthus sinensis in advance, the whole part from the root part to the residual leaf part of the miscanthus sinensis is wetted, the degradable non-woven fabric sealing space is full of water, and the environment is contrary to the current season, the miscanthus sinensis is prevented from breathing, and the diffusion of rotting bacteria is accelerated, so that the miscanthus sinensis is further accelerated to die.
Note that: the term "harmful plants" in this embodiment means plants including miscanthus which affect forest recovery. The degradable non-woven fabric in the scheme is decomposed into organic fertilizer along with the rotted matters in a limited time after the miscanthus is completely rotten.
Compared with the prior art, the invention has the beneficial effects that: the method has the advantages that the miscanthus which needs to be recovered in the forest land is removed through means of environmental protection, safety, natural decay and the like, is made into organic fertilizer, and is planted with wood species or economic tree species in batches according to season time sharing, so that the alien multi-layer mixed good forest stand is formed, the soil is improved, the healthy growth of the forest is promoted, the total accumulation of the forest land and the quality of wood or economic crops are improved, the water and soil conservation and the air purification level are consolidated, the biological diversity is enriched, various benefits of the forest stand are fully exerted, and the fire disaster resistance, the pest control capability and the like are improved.
Detailed Description
The technical scheme of the invention is further specifically described by the following examples.
The method for eliminating miscanthus and recovering forests is carried out in spring or rainy season, the two methods of eliminating directly by manpower and eliminating by using degradable non-woven fabric sealing miscanthus are combined, and objective tree species such as wood tree species or economic tree species are planted in batches at the positions where the front and rear miscanthus are eliminated until excellent forests with different ages and mixed layers are formed.
The present embodiment includes the following:
A. analyzing the distribution condition of the miscanthus sinensis according to the current condition of the required restored forest land, and selecting the miscanthus sinensis range according to two modes of manpower and degradation: wherein, the method directly eliminates 1/3 to 1/2 of the total quantity of the miscanthus sinensis manually, and reserves 1/2 to 2/3 of the miscanthus sinensis to be removed by a degradable non-woven fabric sealing and wrapping mode.
B. According to the near natural principle, when the plant is directly eliminated manually, excellent tree species planted naturally or artificially except for harmful plants (miscanthus sinensis, thorn plants with negative effects on planted trees, small hybrid bamboos and the like) are reserved as much as possible. Among the retained miscanthus, there are natural or artificial cultivated parts of the forest where the miscanthus is to be eliminated within the range of the root system of the tree.
C. According to the near natural principle requirement, proper tree species are selected at proper point positions, and the tree species are planted in a zone which is directly eliminated manually according to the distance of 2-4 meters for the purposes of material utilization, economy and the like.
D. Synchronous with or following C, eliminating by sealing the miscanthus with degradable non-woven fabric. When covering the grass (except for manual direct elimination) which is reserved by sealing the degradable non-woven fabric: covering the front stage to a height of 0.3-0.8 m with a distance of 0.6-1 m, bundling each cluster with straw or degradable vine, and cleaning the harmful plants between clusters.
When the miscanthus sinensis is bundled, the middle part of the miscanthus sinensis is loose along the two ends of the miscanthus sinensis in the height direction, or the spacing section is tight.
E. After the step D is completed, water is sprayed on the miscanthus sinensis. When spraying water, the grass is sprayed from the root to the residual leaf to be wet and thoroughly sprayed as much as possible.
F. When the miscanthus sinensis is fully wet, sealing and covering the miscanthus sinensis by using a degradable non-woven fabric, wherein the degradable non-woven fabric is preferably black fabric, and is made into a bag-shaped body, a tying belt is arranged at the bag opening, and the degradable non-woven fabric positioned at the root of the miscanthus sinensis is tightly stuck to the ground for compacting by using gravels or soil during covering; and the fastening belt is used for fixing by using small wood piles or stones, so that the root is prevented from loosening or the whole bag body is prevented from being blown away by wind.
G. In the next year or the third year, the fully rotted miscanthus parts after sealing are planted with wood or economic tree seeds according to the distance of 1-2 meters. And the same case of the original cleaned zone is planted.
H. The method is used for continuously removing the residual miscanthus sinensis in the required recovery forest land, and reseeding the corresponding wood or economic tree species, and the like, and simultaneously, the planting is also increased in the zone manually removed.
In this embodiment, in the forest land to be restored, the part with poor illumination is preferably manually and directly removed. Because the miscanthus sinensis contains water after being clustered and sealed, sunlight irradiates the periphery of the miscanthus sinensis, and the height Wen Menshao is formed in the sealing bag, so that the rotting of the miscanthus sinensis can be accelerated.
The embodiment uses degradable non-woven fabric to seal miscanthus for elimination, and the elimination is carried out twice a year. When tree species are planted, the forest land is provided with a water source, the planted seedlings are non-woven fabric substrate container seedlings and can not be limited by seasons, and the season adaptability of the planted tree species is considered according to local conditions. When the miscanthus is sprayed wet, the rainwater in spring or rainy season is fully utilized, and the operation is performed after the rainwater is thoroughly discharged.
