    • PROBLEM TO BE SOLVED: To obtain a vegetation net which is not destroyed by running water, avalanche or the like and does not create pollution problems by attaching a wire-netting to one surface of a palm net, attaching a vegetation sheet to other surface, and sewing to one united body with adequate knotting. SOLUTION: A net N is made by sequentially superimposing wire-netting 1, a palm net 2, vegetation sheet 5 a net-like body 7 and sewing them to one united body. For the wire-netting 1, hexagonal or the like is used which has the knotting of 10 to 70 mm and the diameter of wire material of 0.5 to 3 mm. The palm net 2 has the size of raw material of 1 to 10 mm and 5 to 15 members per 10 cm×10 cm. The vegetation sheet 5 has vegetation base materials 6 such as seeds, fertilizer, soil conditioner or the like adhered between two sheets of hydrolytic or water-soluble paper and cloth pieces 3, 4 and raw material for a net-like body 7 is hessian cloth or the like. Sewing thread 8 is biodegradable resin fibrous thread or hemp thread by anticorrosive polyester thread or the like may be also. Thereby, when the net N is laid on the face of slope in a river water zone, its automorphic character is good and the net can be stable adhered to the face of slope.

    • PROBLEM TO BE SOLVED: To obtain a vegetation mat which does not leave residue on the face of slope by attaching a plastic net to one surface of palm mat and attaching a vegetation sheet adhering vegetation base material on hydrolytic paper cloth pieces on the other surface and sewing them together to one united body. SOLUTION: A mat M is made by superimposing a plastic mat 1, palm mat 2, water-soluble or hydrolytic paper and cloth pieces 3, 4, in which vegetation basic materials 6 such as seeds, fertilizers, soil conditioners or the like are adhered, and net body 7 and vegetation sheet 5 are sequentially arranged and formed in one united body. Plastic net 1 is woven to a net with meshes from 5 to 300 mm and is made of a biodegradable synthetic resin. The palm mat 2 is made of palm fibers adhered with an adhesive to a mat shape with the thickness of 0.3 to 10 mm and meshes of 100 to 500 g/m . Sewing thread 8 is a thread of biodegradable resin fibers, hemp thread, cotton thread or the like. Thereby, when the mat M is laid on the face of slope in a region easy to water, the mat is not cut off by the running water without leaving residue thereby creating no water pollution problem.

    • PROBLEM TO BE SOLVED: To successfully vegetate plants, prevent the collapse of a slope, and leave no residual material by fitting a hydrolytic vegetation sheet to one face of a coarse coconut net, and integrally sewing them. SOLUTION: A hydrolytic vegetation sheet 3 is fitted to one face of a coarse coconut net 2, and they are integrally sewn at proper knots to form a vegetation net 1. Coconut fiber strands with the diameter 1-10 mm are woven at the rate of 5-15 strands in 10×10 cm to form the coconut net 2, and a biodegradable synthetic resin fiber thread is used as a suture. The vegetation sheet 3 is constituted of water-soluble paper 4a, 4b, a vegetation substrate 5, and a mosquito net texture 6. When the vegetation net 1 is arranged in the low water area of a river, the sprouting and growth of seeds are accelerated, plants are successfully vegetated, and the collapse of a slope surface is effectively prevented. The vegetation net 1 is corroded after 2-5 years, and it does not leave a residual material affecting the environment of the river.
