To sow seeds very easily on a slope such as the created ground by forming net legs made of seeder tapes to wrap plant seeds on a net texture main body.

Net legs made of seeder tapes wrapping plant seeds are formed on a net texture main body. The installation work itself of a net texture becomes the sowing work, seeds can be sown very easily, and a net for protecting a slope can be concurrently installed without causing dispersion in the seed quantity. The net legs made of the seeder tapes wrapping plant seeds and net legs made of decomposable fibers or indecomposable fibers are formed on the net texture main body. When the net legs are made of decomposable fibers, they can protect the slope of the soft ground until the decomposable fibers are decomposed after the seeds sprout out. When the net legs are made of indecomposable fibers, they can protect the slope over a long period.
