Description
Technical Field
The invention belongs to the technical field of forest land development, and particularly relates to a method for improving the yield of vegetation under a forest in an under-forest economic forest and grass mode.
Background
The under-forest economy mainly refers to under-forest planting industry, breeding industry, collection industry, forest tourism and health-care industry developed by taking forest land resources and forest ecological environment as the basis. The under-forest planting industry also comprises a forest and poultry mode, a forest and livestock mode, a forest and grass mode, a forest and drug mode, a forest and oil mode and a forest and grain mode.
The mode of forest and grass is characterized in that pasture is planted or naturally grown weeds are reserved in fast-growing forests of returning forests, the influence of the growth of trees on the pasture is small, and the pasture is fed to livestock and poultry after being harvested. Generally speaking, 600 kg of green pasture can be harvested in 1 mu of forest land, and the economic income of about 300 yuan can be obtained.
The cogongrass, also called perfect weeds, has jagged leaves and granular structure, even if goats eat all the grass cannot touch the cogongrass, and the cogongrass burns very violently when being ignited. The cogongrass grass, which likes yang and is drought-enduring, mostly grows on the roadside, hillside and grassland, and the root name thereof is 'cogongrass rhizome'.
Although the cogongrass is generally considered to be one of the most virulent 10 weeds in the world in human eyes, the cogongrass can invade the land, forest and farmland, destroy crops, destroy indigenous plants, overturn the ecosystem and simultaneously be hard to completely kill and remove abnormal stubborn diseases, the cogongrass still has certain medicinal value and commercial value.
The recorded Baimao grass in Shanhai Jing is used as a seat of spirit, a shrine, can be buried randomly and is used for covering a white house. The record of the materia medica justice: bai Mao Gen, cold and cool but sweet in flavor, can clear heat in blood system without damaging dryness or stickiness and greasiness, so it can cool blood without worrying about its accumulation and stasis, so it is indicated for hematemesis, epistaxis and hematemesis. The rhizome of the cogongrass rhizome can be used as a medicine and has the effects of clearing heat, promoting fluid production, cooling blood and stopping bleeding.
Meanwhile, the couch grass leaves can be woven into couch grass sheets for the decoration and rain prevention of the lodging and the couch grass roof, and the market price of the couch grass sheets is about 15 yuan per square meter at present.
However, due to the yang-loving and drought-enduring habit of the cogongrass and the strong ecological destructiveness thereof, the following technical prejudices always exist in the field:
1. the field considers that the open space in the forest is very cool and shady, and the sunshine is insufficient, so that the method is not suitable for planting the cogongrass;
2. the ecological destructiveness of the cogongrass can destroy the original ecology under the forest, damage the original plants on the forest land, and even if the economy under the forest is developed, the cogongrass cannot be considered as the planting object under the forest in the mode of the forest grass.
Disclosure of Invention
Based on the problems in the field, the invention provides a method for improving the yield of the vegetation under the forest in an under-forest economic forest and grass mode, which successfully breaks through the technical bias existing in the prior art, makes the planting of the cogongrass under the forest possible, and simultaneously can obviously improve the yield of the vegetation under the forest and improve the economic benefit.
The technical scheme of the invention is as follows:
a method for enhancing understory vegetation yield for an understory economic forest and grass mode, comprising: and (5) planting the cogongrass in the forest.
The planting refers to scattering grass seeds of the cogongrass in the forest and/or scattering roots and stems of the cogongrass in the forest.
The grass of cogongrassThe scattering density of the seeds is 8000-2Preferably 10000 particles/m2The number of the stem nodes of the rhizome of the cogongrass is 2500-2. The grass seed scattering density of the cogongrass is 10000 grains/m2. The density has the advantages that the growth density of the cogongrass can be controlled within a reasonable range, so that the cogongrass cannot grow and expand too much, and the underground can grow with a large amount of the cogongrass, so that the utilization efficiency of the underground vacant land is highest.
The diameter of the rhizome of the cogongrass is 0.3-0.7cm, preferably 0.5cm, and the rhizome of the cogongrass with the diameter is selected to be sowed and propagated best.
The under forest refers to the under forest open space.
The forest refers to the open space under the rubber forest;
preferably, the forest is selected from the group consisting of rubberwood, elm forest, ailanthus forest, poplar forest, willow forest, birch forest, maple forest, pinus sylvestris forest, oak forest, hornbeam forest, basswood forest, alstonia forest, ash forest, ginkgo forest, eucommia forest.
The yield of the cogongrass in the forest is 2500-2。
The method for improving the yield of the vegetation under the forest in the under-forest economic forest and grass mode is characterized by further comprising the following steps of: harvesting as grass when the height of the cogongrass plant grows to 1.2-1.5 m.
The method for improving the yield of the vegetation under the forest in the under-forest economic forest and grass mode is characterized by further comprising the following steps of: weaving the harvested stalk leaves of the cogongrass into the cogongrass slices.
The invention unexpectedly discovers that the rhizoma imperatae which is grown into the sheet of the rhizoma imperatae after the rhizome of the rhizoma imperatae carelessly scattered under the rubber forest is grown for a period of time is good in growth vigor and does not cause any threat to the original forest of the forest land, because the root system depth of the rhizoma imperatae is shallow and is only 0-0.15m below the ground surface, the root system of the rubber tree is very deep and can usually go deep into the ground by 0.5-3m, and the root systems are not in one layer and do not influence each other. The cogongrass rhizome root system is staggered on the earth surface, so that the ecological effect of solidifying the earth surface to prevent water and soil loss is achieved. In the flowering season, white flowers of a large amount of couch grass are bloomed, and the method is very suitable for providing a beautiful environment that the couch grass blooms one white flower and the rhododendron blooms red for the health-care industry of under-forest economy. Moreover, compared with the original method for planting the grass under the forest, the method for planting the cogongrass under the forest is obviously improved in economic yield, and has the characteristics of vigorous vitality of the cogongrass and no need of extra cost of manpower and material resources for cultivation and supervision, so that the method has the outstanding advantages of effectiveness, simplicity, practicability, low cost, considerable return and the like.
