Composite type alien earth sparging wood fiber, and fabricating method

Abstract

This invention relates to a method for producing composite wood fibers for guest soil spray seeding. The composite wood fibers are composed of: wood fibers, water, surfactant, plant growth regulator and composite fertilizer. Woods fibers with lengths of 40-60 mm and diameters of 1-1.5 mm constitute 65-70%, wood fibers with lengths of 10-40 mm and diameters of 0.3-1.0 mm 25-30%, and wood fibers with lengths of 0.5-10 mm and diameters of 0.1-0.3 mm less than or equal to 5%. The content of the surfactant is 30-60 ppm. The content of the plant growth regulator is less than or equal to 15 ppm. The content of the composite fertilizer is less than or equal to 5%. The water content is less than or equal to 15%. The wood fibers can improve the adhering stability of guest soil to slopes, and can make the matrix covering material moist in a long time, thus can promote the germination and growth of seeds. Besides, the wood fibers do not favor the multiplication of diseases, pests and bacteria.

Description

technical field [0001] The invention relates to a compound guest soil spraying wood fiber used for spraying and sowing herb and woody mixed plant seeds on steep landforms, rocky or earth-rock mixed slopes and a manufacturing method thereof. Background technique [0002] In some areas, due to vegetation damage or ecological damage caused by development and construction, soil loss is extremely serious, and often even the topsoil cannot be maintained. In order to restore the ecology, the methods generally used are: use foamed cement to make a honeycomb structure on the construction surface, and then fill the honeycomb structure with soil and grass seeds; there are also rice straw, wheat straw, degradable chemical fiber, etc. mixed with peat soil, sprayed Applied to wire mesh covered construction surfaces to form a clingable base, providing a topsoil-like effect. But the above methods all have deficiencies. The honeycomb structure formed by foamed cement is not connected to ea...

AI Technical Summary

Problems solved by technology

The honeycomb structure formed by foamed cement is not connected to each other, and cannot form a large area of ​​vegetation, which is not conducive to the growth of plant roots, and larger plants such as shrubs and trees cannot survive; use straw, wheat straw, degradable chemical fiber, etc. and peat The method of soil mixing and spraying can avoid the disadvantages of foamed cement, but rice straw and wheat straw have a layer of wax shell on the surface, which is hydrophobic, and the mixing performance with peat soil is not good, and it is easy to cause the separation of water and mud, and cannot form Uniform and stable mud has short fibers, poor interweaving performance, low organic matter content, and low water retention performance. During and after construction, it will be lost or agglomerated due to the erosion of rainwater. The construction effect and vegetation growth quality are poor, and water and soil regeneration cannot be prevented. At the same time, the grass fiber decays slowly and cannot provide nutrients for new plants; degradable chemical fibers only have the ability to form a network, but cannot provide nutrients or retain water, and the degradation process will inevitably cause damage to the soil and the environment.
