32 results about "Vascular plant" patented technology

Vascular plants (from Latin vasculum: duct), also known as tracheophytes (from the equivalent Greek term trachea), form a large group of plants (c. 308,312 accepted known species) that are defined as those land plants that have lignified tissues (the xylem) for conducting water and minerals throughout the plant. They also have a specialized non-lignified tissue (the phloem) to conduct products of photosynthesis. Vascular plants include the clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants). Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato.

Technique for restraining grass and controlling sludge by using cinder

The invention aims to solve the problems of over spread of large-sized vascular plants in grass-type lakes and over-strong biological deposit-promoting effect and provide a technique and a method for restraining grass and controlling sludge for improving the growing water quality condition of aquatic plants and accelerating bottom sludge decomposition. Iron, aluminum and calcium oxides in cinder can strongly adsorb phosphate radical in the water body, the loose and porous surface of the cinder is favorable for the fixation and growth of soil microbes, and a formed biological membrane can effectively remove organic substances and ammonia nitrogen from the water body and accelerate the biological decomposition of the lake bottom sludge. The cinder is filled in a nylon bag and the nylon bag is fixed in a ground cage for facilitating reclamation and preventing physical deposition at the lake bottom. By using the existing resources in rural areas of China and using the local materials, the method is convenient and feasible, and has strong operability and wide application; and the implementation of the technique does not affect the primary ecological function of the ecosystem of the lake and has significance for maintaining the ecological health of the grass-type lakes for long term.
