[0057] Step six, when the distribution notch containing the eco-bag is facing the top end of the telescopic hose 2, the eco-bag enters the telescopic hose 2 and slides along the telescopic hose 2 to the furrowing tip 21, and then falls into the furrowing groove. As the sowing box 1 drives a pair of load-bearing rollers 35 to move in the grassland, it drives the covering rollers 33 to cover the sown eco-bag with soil.

[0058] The present invention adjusts the sowing row spacing of the eco-bags to provide strong support for the recovery of the grassland ecosystem.
